*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> CHETRD_2STAGE reduces a complex Hermitian matrix A to real symmetric
*> tridiagonal form T by a unitary similarity transformation:
*> Q1**H Q2**H* A * Q2 * Q1 = T.
*> \endverbatim
*
* Arguments:
* ==========
*
*> \param[in] VECT
*> \verbatim
*> VECT is CHARACTER*1
*> = 'N': No need for the Housholder representation,
*> in particular for the second stage (Band to
*> tridiagonal) and thus LHOUS2 is of size max(1, 4*N);
*> = 'V': the Householder representation is needed to
*> either generate Q1 Q2 or to apply Q1 Q2,
*> then LHOUS2 is to be queried and computed.
*> (NOT AVAILABLE IN THIS RELEASE).
*> \endverbatim
*>
*> \param[in] UPLO
*> \verbatim
*> UPLO is CHARACTER*1
*> = 'U': Upper triangle of A is stored;
*> = 'L': Lower triangle of A is stored.
*> \endverbatim
*>
*> \param[in] N
*> \verbatim
*> N is INTEGER
*> The order of the matrix A. N >= 0.
*> \endverbatim
*>
*> \param[in,out] A
*> \verbatim
*> A is COMPLEX array, dimension (LDA,N)
*> On entry, the Hermitian matrix A. If UPLO = 'U', the leading
*> N-by-N upper triangular part of A contains the upper
*> triangular part of the matrix A, and the strictly lower
*> triangular part of A is not referenced. If UPLO = 'L', the
*> leading N-by-N lower triangular part of A contains the lower
*> triangular part of the matrix A, and the strictly upper
*> triangular part of A is not referenced.
*> On exit, if UPLO = 'U', the band superdiagonal
*> of A are overwritten by the corresponding elements of the
*> internal band-diagonal matrix AB, and the elements above
*> the KD superdiagonal, with the array TAU, represent the unitary
*> matrix Q1 as a product of elementary reflectors; if UPLO
*> = 'L', the diagonal and band subdiagonal of A are over-
*> written by the corresponding elements of the internal band-diagonal
*> matrix AB, and the elements below the KD subdiagonal, with
*> the array TAU, represent the unitary matrix Q1 as a product
*> of elementary reflectors. See Further Details.
*> \endverbatim
*>
*> \param[in] LDA
*> \verbatim
*> LDA is INTEGER
*> The leading dimension of the array A. LDA >= max(1,N).
*> \endverbatim
*>
*> \param[out] D
*> \verbatim
*> D is REAL array, dimension (N)
*> The diagonal elements of the tridiagonal matrix T.
*> \endverbatim
*>
*> \param[out] E
*> \verbatim
*> E is REAL array, dimension (N-1)
*> The off-diagonal elements of the tridiagonal matrix T.
*> \endverbatim
*>
*> \param[out] TAU
*> \verbatim
*> TAU is COMPLEX array, dimension (N-KD)
*> The scalar factors of the elementary reflectors of
*> the first stage (see Further Details).
*> \endverbatim
*>
*> \param[out] HOUS2
*> \verbatim
*> HOUS2 is COMPLEX array, dimension LHOUS2, that
*> store the Householder representation of the stage2
*> band to tridiagonal.
*> \endverbatim
*>
*> \param[in] LHOUS2
*> \verbatim
*> LHOUS2 is INTEGER
*> The dimension of the array HOUS2. LHOUS2 = MAX(1, dimension)
*> If LWORK = -1, or LHOUS2=-1,
*> then a query is assumed; the routine
*> only calculates the optimal size of the HOUS2 array, returns
*> this value as the first entry of the HOUS2 array, and no error
*> message related to LHOUS2 is issued by XERBLA.
*> LHOUS2 = MAX(1, dimension) where
*> dimension = 4*N if VECT='N'
*> not available now if VECT='H'
*> \endverbatim
*>
*> \param[out] WORK
*> \verbatim
*> WORK is COMPLEX array, dimension LWORK.
*> \endverbatim
*>
*> \param[in] LWORK
*> \verbatim
*> LWORK is INTEGER
*> The dimension of the array WORK. LWORK = MAX(1, dimension)
*> If LWORK = -1, or LHOUS2=-1,
*> then a workspace query is assumed; the routine
*> only calculates the optimal size of the WORK array, returns
*> this value as the first entry of the WORK array, and no error
*> message related to LWORK is issued by XERBLA.
*> LWORK = MAX(1, dimension) where
*> dimension = max(stage1,stage2) + (KD+1)*N
*> = N*KD + N*max(KD+1,FACTOPTNB)
*> + max(2*KD*KD, KD*NTHREADS)
*> + (KD+1)*N
*> where KD is the blocking size of the reduction,
*> FACTOPTNB is the blocking used by the QR or LQ
*> algorithm, usually FACTOPTNB=128 is a good choice
*> NTHREADS is the number of threads used when
*> openMP compilation is enabled, otherwise =1.
*> \endverbatim
*>
*> \param[out] INFO

Package fmt implements formatted I/O with functions analogous
to C's printf and scanf. The format 'verbs' are derived from C's but
are simpler.
Printing
The verbs:
General:
%v the value in a default format
when printing structs, the plus flag (%+v) adds field names
%#v a Go-syntax representation of the value
%T a Go-syntax representation of the type of the value
%% a literal percent sign; consumes no value
Boolean:
%t the word true or false
Integer:
%b base 2
%c the character represented by the corresponding Unicode code point
%d base 10
%o base 8
%q a single-quoted character literal safely escaped with Go syntax.
%x base 16, with lower-case letters for a-f
%X base 16, with upper-case letters for A-F
%U Unicode format: U+1234; same as "U+%04X"
Floating-point and complex constituents:
%b decimalless scientific notation with exponent a power of two,
in the manner of strconv.FormatFloat with the 'b' format,
e.g. -123456p-78
%e scientific notation, e.g. -1234.456e+78
%E scientific notation, e.g. -1234.456E+78
%f decimal point but no exponent, e.g. 123.456
%F synonym for %f
%g whichever of %e or %f produces more compact output
%G whichever of %E or %f produces more compact output
String and slice of bytes:
%s the uninterpreted bytes of the string or slice
%q a double-quoted string safely escaped with Go syntax
%x base 16, lower-case, two characters per byte
%X base 16, upper-case, two characters per byte
Pointer:
%p base 16 notation, with leading 0x
There is no 'u' flag. Integers are printed unsigned if they have unsigned type.
Similarly, there is no need to specify the size of the operand (int8, int64).
The default format for %v is:
bool: %t
int, int8 etc.: %d
uint, uint8 etc.: %d, %x if printed with %#v
float32, complex64, etc: %g
string: %s
chan: %p
pointer: %p
For compound objects, the elements are printed using these rules, recursively,
laid out like this:
struct: {field0 field1 ...}
array, slice: [elem0 elem1 ...]
maps: map[key1:value1 key2:value2]
pointer to above: &{}, &[], &map[]
Width is specified by an optional decimal number immediately following the verb.
If absent, the width is whatever is necessary to represent the value.
Precision is specified after the (optional) width by a period followed by a
decimal number. If no period is present, a default precision is used.
A period with no following number specifies a precision of zero.
Examples:
%f: default width, default precision
%9f width 9, default precision
%.2f default width, precision 2
%9.2f width 9, precision 2
%9.f width 9, precision 0
Width and precision are measured in units of Unicode code points,
that is, runes. (This differs from C's printf where the
units are always measured in bytes.) Either or both of the flags
may be replaced with the character '*', causing their values to be
obtained from the next operand, which must be of type int.
For most values, width is the minimum number of runes to output,
padding the formatted form with spaces if necessary.
For strings, byte slices and byte arrays, however, precision
limits the length of the input to be formatted (not the size of
the output), truncating if necessary. Normally it is measured in
runes, but for these types when formatted with the %x or %X format
it is measured in bytes.
For floating-point values, width sets the minimum width of the field and
precision sets the number of places after the decimal, if appropriate,
except that for %g/%G it sets the total number of digits. For example,
given 123.45 the format %6.2f prints 123.45 while %.4g prints 123.5.
The default precision for %e and %f is 6; for %g it is the smallest
number of digits necessary to identify the value uniquely.
For complex numbers, the width and precision apply to the two
components independently and the result is parenthesized, so %f applied
to 1.2+3.4i produces (1.200000+3.400000i).
Other flags:
+ always print a sign for numeric values;
guarantee ASCII-only output for %q (%+q)
- pad with spaces on the right rather than the left (left-justify the field)
# alternate format: add leading 0 for octal (%#o), 0x for hex (%#x);
0X for hex (%#X); suppress 0x for %p (%#p);
for %q, print a raw (backquoted) string if strconv.CanBackquote
returns true;
write e.g. U+0078 'x' if the character is printable for %U (%#U).
' ' (space) leave a space for elided sign in numbers (% d);
put spaces between bytes printing strings or slices in hex (% x, % X)
0 pad with leading zeros rather than spaces;
for numbers, this moves the padding after the sign
Flags are ignored by verbs that do not expect them.
For example there is no alternate decimal format, so %#d and %d
behave identically.
For each Printf-like function, there is also a Print function
that takes no format and is equivalent to saying %v for every
operand. Another variant Println inserts blanks between
operands and appends a newline.
Regardless of the verb, if an operand is an interface value,
the internal concrete value is used, not the interface itself.
Thus:
var i interface{} = 23
fmt.Printf("%v\n", i)
will print 23.
Except when printed using the verbs %T and %p, special
formatting considerations apply for operands that implement
certain interfaces. In order of application:
1. If an operand implements the Formatter interface, it will
be invoked. Formatter provides fine control of formatting.
2. If the %v verb is used with the # flag (%#v) and the operand
implements the GoStringer interface, that will be invoked.
If the format (which is implicitly %v for Println etc.) is valid
for a string (%s %q %v %x %X), the following two rules apply:
3. If an operand implements the error interface, the Error method
will be invoked to convert the object to a string, which will then
be formatted as required by the verb (if any).
4. If an operand implements method String() string, that method
will be invoked to convert the object to a string, which will then
be formatted as required by the verb (if any).
For compound operands such as slices and structs, the format
applies to the elements of each operand, recursively, not to the
operand as a whole. Thus %q will quote each element of a slice
of strings, and %6.2f will control formatting for each element
of a floating-point array.
To avoid recursion in cases such as
type X string
func (x X) String() string { return Sprintf("<%s>", x) }
convert the value before recurring:
func (x X) String() string { return Sprintf("<%s>", string(x)) }
Infinite recursion can also be triggered by self-referential data
structures, such as a slice that contains itself as an element, if
that type has a String method. Such pathologies are rare, however,
and the package does not protect against them.
Explicit argument indexes:
In Printf, Sprintf, and Fprintf, the default behavior is for each
formatting verb to format successive arguments passed in the call.
However, the notation [n] immediately before the verb indicates that the
nth one-indexed argument is to be formatted instead. The same notation
before a '*' for a width or precision selects the argument index holding
the value. After processing a bracketed expression [n], arguments n+1,
n+2, etc. will be processed unless otherwise directed.
For example,
fmt.Sprintf("%[2]d %[1]d\n", 11, 22)
will yield "22 11", while
fmt.Sprintf("%[3]*.[2]*[1]f", 12.0, 2, 6),
equivalent to
fmt.Sprintf("%6.2f", 12.0),
will yield " 12.00". Because an explicit index affects subsequent verbs,
this notation can be used to print the same values multiple times
by resetting the index for the first argument to be repeated:
fmt.Sprintf("%d %d %#[1]x %#x", 16, 17)
will yield "16 17 0x10 0x11".
Format errors:
If an invalid argument is given for a verb, such as providing
a string to %d, the generated string will contain a
description of the problem, as in these examples:
Wrong type or unknown verb: %!verb(type=value)
Printf("%d", hi): %!d(string=hi)
Too many arguments: %!(EXTRA type=value)
Printf("hi", "guys"): hi%!(EXTRA string=guys)
Too few arguments: %!verb(MISSING)
Printf("hi%d"): hi %!d(MISSING)
Non-int for width or precision: %!(BADWIDTH) or %!(BADPREC)
Printf("%*s", 4.5, "hi"): %!(BADWIDTH)hi
Printf("%.*s", 4.5, "hi"): %!(BADPREC)hi
Invalid or invalid use of argument index: %!(BADINDEX)
Printf("%*[2]d", 7): %!d(BADINDEX)
Printf("%.[2]d", 7): %!d(BADINDEX)
All errors begin with the string "%!" followed sometimes
by a single character (the verb) and end with a parenthesized
description.
If an Error or String method triggers a panic when called by a
print routine, the fmt package reformats the error message
from the panic, decorating it with an indication that it came
through the fmt package. For example, if a String method
calls panic("bad"), the resulting formatted message will look
like
%!s(PANIC=bad)
The %!s just shows the print verb in use when the failure
occurred.
Scanning
An analogous set of functions scans formatted text to yield
values. Scan, Scanf and Scanln read from os.Stdin; Fscan,
Fscanf and Fscanln read from a specified io.Reader; Sscan,
Sscanf and Sscanln read from an argument string. Scanln,
Fscanln and Sscanln stop scanning at a newline and require that
the items be followed by one; Scanf, Fscanf and Sscanf require
newlines in the input to match newlines in the format; the other
routines treat newlines as spaces.
Scanf, Fscanf, and Sscanf parse the arguments according to a
format string, analogous to that of Printf. For example, %x
will scan an integer as a hexadecimal number, and %v will scan
the default representation format for the value.
The formats behave analogously to those of Printf with the
following exceptions:
%p is not implemented
%T is not implemented
%e %E %f %F %g %G are all equivalent and scan any floating point or complex value
%s and %v on strings scan a space-delimited token
Flags # and + are not implemented.
The familiar base-setting prefixes 0 (octal) and 0x
(hexadecimal) are accepted when scanning integers without a
format or with the %v verb.
Width is interpreted in the input text (%5s means at most
five runes of input will be read to scan a string) but there
is no syntax for scanning with a precision (no %5.2f, just
%5f).
When scanning with a format, all non-empty runs of space
characters (except newline) are equivalent to a single
space in both the format and the input. With that proviso,
text in the format string must match the input text; scanning
stops if it does not, with the return value of the function
indicating the number of arguments scanned.
In all the scanning functions, a carriage return followed
immediately by a newline is treated as a plain newline
(\r\n means the same as \n).
In all the scanning functions, if an operand implements method
Scan (that is, it implements the Scanner interface) that
method will be used to scan the text for that operand. Also,
if the number of arguments scanned is less than the number of
arguments provided, an error is returned.
All arguments to be scanned must be either pointers to basic
types or implementations of the Scanner interface.
Note: Fscan etc. can read one character (rune) past the input
they return, which means that a loop calling a scan routine
may skip some of the input. This is usually a problem only
when there is no space between input values. If the reader
provided to Fscan implements ReadRune, that method will be used
to read characters. If the reader also implements UnreadRune,
that method will be used to save the character and successive
calls will not lose data. To attach ReadRune and UnreadRune
methods to a reader without that capability, use
bufio.NewReader.

@deprecated

In order to store defaults for a class, a prototype may need to create
a default meta object, which will be inherited by any objects instantiated
from the class's constructor.
However, the properties of that meta object are only shallow-cloned,
so if a property is a hash (like the event system's `listeners` hash),
it will by default be shared across all instances of that class.
This method allows extensions to deeply clone a series of nested hashes or
other complex objects. For instance, the event system might pass
`['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
walk down the keys provided.
For each key, if the key does not exist, it is created. If it already
exists and it was inherited from its constructor, the constructor's
key is cloned.
You can also pass false for `writable`, which will simply return
undefined if `prepareMetaPath` discovers any part of the path that
shared or undefined.

The purpose of the Ember Instrumentation module is
to provide efficient, general-purpose instrumentation
for Ember.
Subscribe to a listener by using `Ember.subscribe`:
```javascript
Ember.subscribe("render", {
before: function(name, timestamp, payload) {
},
after: function(name, timestamp, payload) {
}
});
```
If you return a value from the `before` callback, that same
value will be passed as a fourth parameter to the `after`
callback.
Instrument a block of code by using `Ember.instrument`:
```javascript
Ember.instrument("render.handlebars", payload, function() {
// rendering logic
}, binding);
```
Event names passed to `Ember.instrument` are namespaced
by periods, from more general to more specific. Subscribers
can listen for events by whatever level of granularity they
are interested in.
In the above example, the event is `render.handlebars`,
and the subscriber listened for all events beginning with
`render`. It would receive callbacks for events named
`render`, `render.handlebars`, `render.container`, or
even `render.handlebars.layout`.

JavaScript (before ES6) does not have a Map implementation. Objects,
which are often used as dictionaries, may only have Strings as keys.
Because Ember has a way to get a unique identifier for every object
via `Ember.guidFor`, we can implement a performant Map with arbitrary
keys. Because it is commonly used in low-level bookkeeping, Map is
implemented as a pure JavaScript object for performance.
This implementation follows the current iteration of the ES6 proposal for
maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
with two exceptions. First, because we need our implementation to be pleasant
on older browsers, we do not use the `delete` name (using `remove` instead).
Second, as we do not have the luxury of in-VM iteration, we implement a
forEach method for iteration.
Map is mocked out to look like an Ember object, so you can do
`Ember.Map.create()` for symmetry with other Ember classes.

NOTE: This is a low-level method used by other parts of the API. You almost
never want to call this method directly. Instead you should use
`Ember.mixin()` to define new properties.
Defines a property on an object. This method works much like the ES5
`Object.defineProperty()` method except that it can also accept computed
properties and other special descriptors.
Normally this method takes only three parameters. However if you pass an
instance of `Ember.Descriptor` as the third param then you can pass an
optional value as the fourth parameter. This is often more efficient than
creating new descriptor hashes for each property.
## Examples
```javascript
// ES5 compatible mode
Ember.defineProperty(contact, 'firstName', {
writable: true,
configurable: false,
enumerable: true,
value: 'Charles'
});
// define a simple property
Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
// define a computed property
Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
return this.firstName+' '+this.lastName;
}).property('firstName', 'lastName'));
```
@method defineProperty
@for Ember
@param {Object} obj the object to define this property on. This may be a prototype.
@param {String} keyName the name of the property
@param {Ember.Descriptor} [desc] an instance of `Ember.Descriptor` (typically a
computed property) or an ES5 descriptor.
You must provide this or `data` but not both.
@param {*} [data] something other than a descriptor, that will
become the explicit value of this property.

Ember.run.scheduleOnce('actions', myContext, function() { console.log("Closure"); });
}
scheduleIt();
scheduleIt();

```javascript
Ember.run.next(myContext, function(){
// code to be executed in the next run loop, which will be scheduled after the current one
});
```
Multiple operations scheduled with `Ember.run.next` will coalesce
into the same later run loop, along with any other operations
scheduled by `Ember.run.later` that expire right around the same
time that `Ember.run.next` operations will fire.
Note that there are often alternatives to using `Ember.run.next`.
For instance, if you'd like to schedule an operation to happen
after all DOM element operations have completed within the current
run loop, you can make use of the `afterRender` run loop queue (added
by the `ember-views` package, along with the preceding `render` queue
where all the DOM element operations happen). Example:
```javascript
App.MyCollectionView = Ember.CollectionView.extend({
didInsertElement: function() {
Ember.run.scheduleOnce('afterRender', this, 'processChildElements');
},
processChildElements: function() {
// ... do something with collectionView's child view
// elements after they've finished rendering, which
// can't be done within the CollectionView's
// `didInsertElement` hook because that gets run
// before the child elements have been added to the DOM.
}
});
```
One benefit of the above approach compared to using `Ember.run.next` is
that you will be able to perform DOM/CSS operations before unprocessed
elements are rendered to the screen, which may prevent flickering or
other artifacts caused by delaying processing until after rendering.
The other major benefit to the above approach is that `Ember.run.next`
introduces an element of non-determinism, which can make things much
harder to test, due to its reliance on `setTimeout`; it's much harder
to guarantee the order of scheduled operations when they are scheduled
outside of the current run loop, i.e. with `Ember.run.next`.

/**
An `Ember.Binding` connects the properties of two objects so that whenever
the value of one property changes, the other property will be changed also.
## Automatic Creation of Bindings with `/^*Binding/`-named Properties
You do not usually create Binding objects directly but instead describe
bindings in your class or object definition using automatic binding
detection.
Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
instances. The value of this property should be a string representing a path
to another object or a custom binding instanced created using Binding helpers
(see "One Way Bindings"):
```
valueBinding: "MyApp.someController.title"
```
This will create a binding from `MyApp.someController.title` to the `value`
property of your object instance automatically. Now the two values will be
kept in sync.
## One Way Bindings
One especially useful binding customization you can use is the `oneWay()`
helper. This helper tells Ember that you are only interested in
receiving changes on the object you are binding from. For example, if you
are binding to a preference and you want to be notified if the preference
has changed, but your object will not be changing the preference itself, you
could do:
```
bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
```
This way if the value of `MyApp.preferencesController.bigTitles` changes the
`bigTitles` property of your object will change also. However, if you
change the value of your `bigTitles` property, it will not update the
`preferencesController`.
One way bindings are almost twice as fast to setup and twice as fast to
execute because the binding only has to worry about changes to one side.
You should consider using one way bindings anytime you have an object that
may be created frequently and you do not intend to change a property; only
to monitor it for changes (such as in the example above).
## Adding Bindings Manually
All of the examples above show you how to configure a custom binding, but the
result of these customizations will be a binding template, not a fully active
Binding instance. The binding will actually become active only when you
instantiate the object the binding belongs to. It is useful however, to
understand what actually happens when the binding is activated.
For a binding to function it must have at least a `from` property and a `to`
property. The `from` property path points to the object/key that you want to
bind from while the `to` path points to the object/key you want to bind to.
When you define a custom binding, you are usually describing the property
you want to bind from (such as `MyApp.someController.value` in the examples
above). When your object is created, it will automatically assign the value
you want to bind `to` based on the name of your binding key. In the
examples above, during init, Ember objects will effectively call
something like this on your binding:
```javascript
binding = Ember.Binding.from(this.valueBinding).to("value");
```
This creates a new binding instance based on the template you provide, and
sets the to path to the `value` property of the new object. Now that the
binding is fully configured with a `from` and a `to`, it simply needs to be
connected to become active. This is done through the `connect()` method:
```javascript
binding.connect(this);
```
Note that when you connect a binding you pass the object you want it to be
connected to. This object will be used as the root for both the from and
to side of the binding when inspecting relative paths. This allows the
binding to be automatically inherited by subclassed objects as well.
Now that the binding is connected, it will observe both the from and to side
and relay changes.
If you ever needed to do so (you almost never will, but it is useful to
understand this anyway), you could manually create an active binding by
using the `Ember.bind()` helper method. (This is the same method used by
to setup your bindings on objects):
```javascript
Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
```
Both of these code fragments have the same effect as doing the most friendly
form of binding creation like so:
```javascript
MyApp.anotherObject = Ember.Object.create({
valueBinding: "MyApp.someController.value",
// OTHER CODE FOR THIS OBJECT...
});
```
Ember's built in binding creation method makes it easy to automatically
create bindings for you. You should always use the highest-level APIs
available, even if you understand how it works underneath.

The `property` extension of Javascript's Function prototype is available
when `Ember.EXTEND_PROTOTYPES` or `Ember.EXTEND_PROTOTYPES.Function` is
`true`, which is the default.
Computed properties allow you to treat a function like a property:
```javascript
MyApp.president = Ember.Object.create({
firstName: "Barack",
lastName: "Obama",
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Call this flag to mark the function as a property
}.property()
});
MyApp.president.get('fullName'); // "Barack Obama"
```
Treating a function like a property is useful because they can work with
bindings, just like any other property.
Many computed properties have dependencies on other properties. For
example, in the above example, the `fullName` property depends on
`firstName` and `lastName` to determine its value. You can tell Ember
about these dependencies like this:
```javascript
MyApp.president = Ember.Object.create({
firstName: "Barack",
lastName: "Obama",
fullName: function() {
return this.get('firstName') + ' ' + this.get('lastName');
// Tell Ember.js that this computed property depends on firstName
// and lastName
}.property('firstName', 'lastName')
});
```
Make sure you list these dependencies so Ember knows when to update
bindings that connect to a computed property. Changing a dependency
will not immediately trigger an update of the computed property, but
will instead clear the cache so that it is updated when the next `get`
is called on the property.

/**
This mixin defines the common interface implemented by enumerable objects
in Ember. Most of these methods follow the standard Array iteration
API defined up to JavaScript 1.8 (excluding language-specific features that
cannot be emulated in older versions of JavaScript).
This mixin is applied automatically to the Array class on page load, so you
can use any of these methods on simple arrays. If Array already implements
one of these methods, the mixin will not override them.
## Writing Your Own Enumerable
To make your own custom class enumerable, you need two items:
1. You must have a length property. This property should change whenever
the number of items in your enumerable object changes. If you using this
with an `Ember.Object` subclass, you should be sure to change the length
property using `set().`
2. If you must implement `nextObject().` See documentation.
Once you have these two methods implement, apply the `Ember.Enumerable` mixin
to your class and you will be able to enumerate the contents of your object
like any other collection.
## Using Ember Enumeration with Other Libraries
Many other libraries provide some kind of iterator or enumeration like
facility. This is often where the most common API conflicts occur.
Ember's API is designed to be as friendly as possible with other
libraries by implementing only methods that mostly correspond to the
JavaScript 1.8 API.

/**
Implement this method to make your class enumerable.
This method will be call repeatedly during enumeration. The index value
will always begin with 0 and increment monotonically. You don't have to
rely on the index value to determine what object to return, but you should
always check the value and start from the beginning when you see the
requested index is 0.
The `previousObject` is the object that was returned from the last call
to `nextObject` for the current iteration. This is a useful way to
manage iteration if you are tracing a linked list, for example.
Finally the context parameter will always contain a hash you can use as
a "scratchpad" to maintain any other state you need in order to iterate
properly. The context object is reused and is not reset between
iterations so make sure you setup the context with a fresh state whenever
the index parameter is 0.
Generally iterators will continue to call `nextObject` until the index
reaches the your current length-1. If you run out of data before this
time for some reason, you should simply return undefined.
The default implementation of this method simply looks up the index.
This works great on any Array-like objects.
@method nextObject
@param {Number} index the current index of the iteration

/**
This module implements Observer-friendly Array-like behavior. This mixin is
picked up by the Array class as well as other controllers, etc. that want to
appear to be arrays.
Unlike `Ember.Enumerable,` this mixin defines methods specifically for
collections that provide index-ordered access to their contents. When you
are designing code that needs to accept any kind of Array-like object, you
should use these methods instead of Array primitives because these will
properly notify observers of changes to the array.
Although these methods are efficient, they do add a layer of indirection to
your application so it is a good idea to use them only when you need the
flexibility of using both true JavaScript arrays and "virtual" arrays such
as controllers and collections.
You can use the methods defined in this module to access and modify array
contents in a KVO-friendly way. You can also be notified whenever the
membership of an array changes by changing the syntax of the property to
`.observes('*myProperty.[]')`.
To support `Ember.Array` in your own class, you must override two
primitives to use it: `replace()` and `objectAt()`.
Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
mixin. All `Ember.Array`-like objects are also enumerable.

/**
The `Ember.Freezable` mixin implements some basic methods for marking an
object as frozen. Once an object is frozen it should be read only. No changes
may be made the internal state of the object.
## Enforcement
To fully support freezing in your subclass, you must include this mixin and
override any method that might alter any property on the object to instead
raise an exception. You can check the state of an object by checking the
`isFrozen` property.
Although future versions of JavaScript may support language-level freezing
object objects, that is not the case today. Even if an object is freezable,
it is still technically possible to modify the object, even though it could
break other parts of your application that do not expect a frozen object to
change. It is, therefore, very important that you always respect the
`isFrozen` property on all freezable objects.
## Example Usage
The example below shows a simple object that implement the `Ember.Freezable`
protocol.
```javascript
Contact = Ember.Object.extend(Ember.Freezable, {
firstName: null,
lastName: null,
// swaps the names
swapNames: function() {
if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
var tmp = this.get('firstName');
this.set('firstName', this.get('lastName'));
this.set('lastName', tmp);
return this;
}
});
c = Context.create({ firstName: "John", lastName: "Doe" });
c.swapNames(); // returns c
c.freeze();
c.swapNames(); // EXCEPTION
```
## Copying
Usually the `Ember.Freezable` protocol is implemented in cooperation with the
`Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
return a frozen object, if the object implements this method as well.
@class Freezable
@namespace Ember
@extends Ember.Mixin
@since Ember 0.9
*/
Ember.Freezable = Ember.Mixin.create(/** @scope Ember.Freezable.prototype */ {
/**
Set to `true` when the object is frozen. Use this property to detect
whether your object is frozen or not.
@property isFrozen
@type Boolean
*/
isFrozen: false,
/**

no longer allow any properties to be edited.
@method freeze
@return {Object} receiver
*/
freeze: function() {
if (get(this, 'isFrozen')) return this;
set(this, 'isFrozen', true);
return this;
}
});
Ember.FROZEN_ERROR = "Frozen object cannot be modified.";

@submodule ember-runtime
*/
var forEach = Ember.EnumerableUtils.forEach;
/**
This mixin defines the API for modifying generic enumerables. These methods
can be applied to an object regardless of whether it is ordered or
unordered.
Note that an Enumerable can change even if it does not implement this mixin.
For example, a MappedEnumerable cannot be directly modified but if its
underlying enumerable changes, it will change also.
## Adding Objects
To add an object to an enumerable, use the `addObject()` method. This
method will only add the object to the enumerable if the object is not
already present and is of a type supported by the enumerable.
```javascript
set.addObject(contact);
```
## Removing Objects
To remove an object from an enumerable, use the `removeObject()` method. This
will only remove the object if it is present in the enumerable, otherwise
this method has no effect.
```javascript
set.removeObject(contact);
```

tests, be sure to apply the Ember.MutableEnumerableTests to your object.

## Overview
This mixin provides properties and property observing functionality, core
features of the Ember object model.
Properties and observers allow one object to observe changes to a
property on another object. This is one of the fundamental ways that
models, controllers and views communicate with each other in an Ember
application.
Any object that has this mixin applied can be used in observer
operations. That includes `Ember.Object` and most objects you will
interact with as you write your Ember application.
Note that you will not generally apply this mixin to classes yourself,
but you will use the features provided by this module frequently, so it
is important to understand how to use it.
## Using `get()` and `set()`
Because of Ember's support for bindings and observers, you will always
access properties using the get method, and set properties using the
set method. This allows the observing objects to be notified and
computed properties to be handled properly.
More documentation about `get` and `set` are below.
## Observing Property Changes
You typically observe property changes simply by adding the `observes`
call to the end of your method declarations in classes that you write.
For example:
```javascript
Ember.Object.extend({
valueObserver: function() {
// Executes whenever the "value" property changes
}.observes('value')
});
```
Although this is the most common way to add an observer, this capability
is actually built into the `Ember.Object` class on top of two methods
defined in this mixin: `addObserver` and `removeObserver`. You can use
these two methods to add and remove observers yourself if you need to
do so at runtime.
To add an observer for a property, call:
```javascript
object.addObserver('propertyKey', targetObject, targetAction)
```
This will call the `targetAction` method on the `targetObject` whenever
the value of the `propertyKey` changes.
Note that if `propertyKey` is a computed property, the observer will be
called when any of the property dependencies are changed, even if the
resulting value of the computed property is unchanged. This is necessary
because computed properties are not computed until `get` is called.
@class Observable
@namespace Ember
@extends Ember.Mixin
*/
Ember.Observable = Ember.Mixin.create(/** @scope Ember.Observable.prototype */ {
/**
Retrieves the value of a property from the object.
This method is usually similar to using `object[keyName]` or `object.keyName`,
however it supports both computed properties and the unknownProperty
handler.
Because `get` unifies the syntax for accessing all these kinds
of properties, it can make many refactorings easier, such as replacing a
simple property with a computed property, or vice versa.
### Computed Properties
Computed properties are methods defined with the `property` modifier
declared at the end, such as:
```javascript
fullName: function() {
return this.getEach('firstName', 'lastName').compact().join(' ');
}.property('firstName', 'lastName')
```
When you call `get` on a computed property, the function will be
called and the return value will be returned instead of the function
itself.
### Unknown Properties
Likewise, if you try to call `get` on a property whose value is
`undefined`, the `unknownProperty()` method will be called on the object.
If this method returns any value other than `undefined`, it will be returned
instead. This allows you to implement "virtual" properties that are
not defined upfront.
@method get
@param {String} keyName The property to retrieve
@return {Object} The property value or undefined.
*/
get: function(keyName) {
return get(this, keyName);
},
/**
To get multiple properties at once, call `getProperties`
with a list of strings or an array:
```javascript
record.getProperties('firstName', 'lastName', 'zipCode'); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
is equivalent to:
```javascript
record.getProperties(['firstName', 'lastName', 'zipCode']); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
@method getProperties
@param {String...|Array} list of keys to get
@return {Hash}
*/
getProperties: function() {
var ret = {};
var propertyNames = arguments;
if (arguments.length === 1 && Ember.typeOf(arguments[0]) === 'array') {
propertyNames = arguments[0];
}
for(var i = 0; i < propertyNames.length; i++) {
ret[propertyNames[i]] = get(this, propertyNames[i]);
}
return ret;
},
/**
Sets the provided key or path to the value.
This method is generally very similar to calling `object[key] = value` or
`object.key = value`, except that it provides support for computed
properties, the `unknownProperty()` method and property observers.
### Computed Properties
If you try to set a value on a key that has a computed property handler
defined (see the `get()` method for an example), then `set()` will call
that method, passing both the value and key instead of simply changing
the value itself. This is useful for those times when you need to
implement a property that is composed of one or more member
properties.
### Unknown Properties
If you try to set a value on a key that is undefined in the target
object, then the `unknownProperty()` handler will be called instead. This
gives you an opportunity to implement complex "virtual" properties that
are not predefined on the object. If `unknownProperty()` returns
undefined, then `set()` will simply set the value on the object.
### Property Observers
In addition to changing the property, `set()` will also register a property
change with the object. Unless you have placed this call inside of a
`beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
(i.e. observer methods declared on the same object), will be called
immediately. Any "remote" observers (i.e. observer methods declared on
another object) will be placed in a queue and called at a later time in a
coalesced manner.
### Chaining
In addition to property changes, `set()` returns the value of the object
itself so you can do chaining like this:
```javascript
record.set('firstName', 'Charles').set('lastName', 'Jolley');
```
@method set
@param {String} keyName The property to set
@param {Object} value The value to set or `null`.
@return {Ember.Observable}
*/
set: function(keyName, value) {
set(this, keyName, value);
return this;
},
/**
To set multiple properties at once, call `setProperties`
with a Hash:
```javascript
record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
```

@param {Hash} hash the hash of keys and values to set

setProperties: function(hash) {
return Ember.setProperties(this, hash);
},

addBeforeObserver: function(key, target, method) {

/**
Adds an observer on a property.
This is the core method used to register an observer for a property.
Once you call this method, any time the key's value is set, your observer
will be notified. Note that the observers are triggered any time the
value is set, regardless of whether it has actually changed. Your
observer should be prepared to handle that.
You can also pass an optional context parameter to this method. The
context will be passed to your observer method whenever it is triggered.
Note that if you add the same target/method pair on a key multiple times
with different context parameters, your observer will only be called once
with the last context you passed.
### Observer Methods
Observer methods you pass should generally have the following signature if
you do not pass a `context` parameter:
```javascript
fooDidChange: function(sender, key, value, rev) { };
```
The sender is the object that changed. The key is the property that
changes. The value property is currently reserved and unused. The rev
is the last property revision of the object when it changed, which you can
use to detect if the key value has really changed or not.
If you pass a `context` parameter, the context will be passed before the
revision like so:
```javascript
fooDidChange: function(sender, key, value, context, rev) { };
```
Usually you will not need the value, context or revision parameters at
the end. In this case, it is common to write observer methods that take
only a sender and key value as parameters or, if you aren't interested in
any of these values, to write an observer that has no parameters at all.

@param {String} key The key to observer

Defines the properties that will be concatenated from the superclass
(instead of overridden).
By default, when you extend an Ember class a property defined in
the subclass overrides a property with the same name that is defined
in the superclass. However, there are some cases where it is preferable
to build up a property's value by combining the superclass' property
value with the subclass' value. An example of this in use within Ember
is the `classNames` property of `Ember.View`.
Here is some sample code showing the difference between a concatenated
property and a normal one:
```javascript
App.BarView = Ember.View.extend({
someNonConcatenatedProperty: ['bar'],
classNames: ['bar']
});
App.FooBarView = App.BarView.extend({
someNonConcatenatedProperty: ['foo'],
classNames: ['foo'],
});
var fooBarView = App.FooBarView.create();
fooBarView.get('someNonConcatenatedProperty'); // ['foo']
fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
```
This behavior extends to object creation as well. Continuing the
above example:
```javascript
var view = App.FooBarView.create({
someNonConcatenatedProperty: ['baz'],
classNames: ['baz']
})
view.get('someNonConcatenatedProperty'); // ['baz']
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Adding a single property that is not an array will just add it in the array:
```javascript
var view = App.FooBarView.create({
classNames: 'baz'
})
view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
```
Using the `concatenatedProperties` property, we can tell to Ember that mix
the content of the properties.
In `Ember.View` the `classNameBindings` and `attributeBindings` properties
are also concatenated, in addition to `classNames`.
This feature is available for you to use throughout the Ember object model,
although typical app developers are likely to use it infrequently.

An ArrayProxy wraps any other object that implements `Ember.Array` and/or

/**
An unordered collection of objects.
A Set works a bit like an array except that its items are not ordered. You
can create a set to efficiently test for membership for an object. You can
also iterate through a set just like an array, even accessing objects by
index, however there is no guarantee as to their order.
All Sets are observable via the Enumerable Observer API - which works
on any enumerable object including both Sets and Arrays.
## Creating a Set
You can create a set like you would most objects using
`new Ember.Set()`. Most new sets you create will be empty, but you can
also initialize the set with some content by passing an array or other
enumerable of objects to the constructor.
Finally, you can pass in an existing set and the set will be copied. You
can also create a copy of a set by calling `Ember.Set#copy()`.
```javascript
// creates a new empty set
var foundNames = new Ember.Set();
// creates a set with four names in it.
var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
// creates a copy of the names set.
var namesCopy = new Ember.Set(names);
// same as above.
var anotherNamesCopy = names.copy();
```
## Adding/Removing Objects
You generally add or remove objects from a set using `add()` or
`remove()`. You can add any type of object including primitives such as
numbers, strings, and booleans.
Unlike arrays, objects can only exist one time in a set. If you call `add()`
on a set with the same object multiple times, the object will only be added
once. Likewise, calling `remove()` with the same object multiple times will
remove the object the first time and have no effect on future calls until
you add the object to the set again.
NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
so will be ignored.
In addition to add/remove you can also call `push()`/`pop()`. Push behaves
just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
object, remove it and return it. This is a good way to use a set as a job
queue when you don't care which order the jobs are executed in.
## Testing for an Object
To test for an object's presence in a set you simply call
`Ember.Set#contains()`.
## Observing changes
When using `Ember.Set`, you can observe the `"[]"` property to be
alerted whenever the content changes. You can also add an enumerable
observer to the set to be notified of specific objects that are added and
removed from the set. See `Ember.Enumerable` for more information on
enumerables.
This is often unhelpful. If you are filtering sets of objects, for instance,
it is very inefficient to re-filter all of the items each time the set
changes. It would be better if you could just adjust the filtered set based
on what was changed on the original set. The same issue applies to merging
sets, as well.
## Other Methods
`Ember.Set` primary implements other mixin APIs. For a complete reference
on the methods you will use with `Ember.Set`, please consult these mixins.
The most useful ones will be `Ember.Enumerable` and
`Ember.MutableEnumerable` which implement most of the common iterator
methods you are used to on Array.
Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
modified. The benefit of this is that when you call `frozenCopy()` on it,
Ember will avoid making copies of the set. This allows you to write
code that can know with certainty when the underlying set data will or
will not be modified.

/**
`Ember.ArrayController` provides a way for you to publish a collection of
objects so that you can easily bind to the collection from a Handlebars
`#each` helper, an `Ember.CollectionView`, or other controllers.
The advantage of using an `ArrayController` is that you only have to set up
your view bindings once; to change what's displayed, simply swap out the
`content` property on the controller.
For example, imagine you wanted to display a list of items fetched via an XHR
request. Create an `Ember.ArrayController` and set its `content` property:
```javascript
MyApp.listController = Ember.ArrayController.create();
$.get('people.json', function(data) {
MyApp.listController.set('content', data);
});
```
Then, create a view that binds to your new controller:
```handlebars
{{#each MyApp.listController}}
{{firstName}} {{lastName}}
{{/each}}
```
Although you are binding to the controller, the behavior of this controller
is to pass through any methods or properties to the underlying array. This
capability comes from `Ember.ArrayProxy`, which this class inherits from.
Sometimes you want to display computed properties within the body of an
`#each` helper that depend on the underlying items in `content`, but are not
present on those items. To do this, set `itemController` to the name of a
controller (probably an `ObjectController`) that will wrap each individual item.
For example:
```handlebars
{{#each post in controller}}
<li>{{title}} ({{titleLength}} characters)</li>
{{/each}}
```
```javascript
App.PostsController = Ember.ArrayController.extend({
itemController: 'post'
});
App.PostController = Ember.ObjectController.extend({
// the `title` property will be proxied to the underlying post.
titleLength: function() {
return this.get('title').length;
}.property('title')
});
```
In some cases it is helpful to return a different `itemController` depending
on the particular item. Subclasses can do this by overriding
`lookupItemController`.
For example:
```javascript
App.MyArrayController = Ember.ArrayController.extend({
lookupItemController: function( object ) {
if (object.get('isSpecial')) {
return "special"; // use App.SpecialController
} else {
return "regular"; // use App.RegularController
}
}
});
```
The itemController instances will have a `parentController` property set to
either the the `parentController` property of the `ArrayController`
or to the `ArrayController` instance itself.

/**
`Ember.View` is the class in Ember responsible for encapsulating templates of
HTML content, combining templates with data to render as sections of a page's
DOM, and registering and responding to user-initiated events.
## HTML Tag
The default HTML tag name used for a view's DOM representation is `div`. This
can be customized by setting the `tagName` property. The following view
class:
```javascript
ParagraphView = Ember.View.extend({
tagName: 'em'
});
```
Would result in instances with the following HTML:
```html
<em id="ember1" class="ember-view"></em>
```
## HTML `class` Attribute
The HTML `class` attribute of a view's tag can be set by providing a
`classNames` property that is set to an array of strings:
```javascript
MyView = Ember.View.extend({
classNames: ['my-class', 'my-other-class']
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view my-class my-other-class"></div>
```
`class` attribute values can also be set by providing a `classNameBindings`
property set to an array of properties names for the view. The return value
of these properties will be added as part of the value for the view's `class`
attribute. These properties can be computed properties:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['propertyA', 'propertyB'],
propertyA: 'from-a',
propertyB: function(){
if(someLogic){ return 'from-b'; }
}.property()
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view from-a from-b"></div>
```
If the value of a class name binding returns a boolean the property name
itself will be used as the class name if the property is true. The class name
will not be added if the value is `false` or `undefined`.
```javascript
MyView = Ember.View.extend({
classNameBindings: ['hovered'],
hovered: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view hovered"></div>
```
When using boolean class name bindings you can supply a string value other
than the property name for use as the `class` HTML attribute by appending the
preferred value after a ":" character when defining the binding:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['awesome:so-very-cool'],
awesome: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view so-very-cool"></div>
```
Boolean value class name bindings whose property names are in a
camelCase-style format will be converted to a dasherized format:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['isUrgent'],
isUrgent: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view is-urgent"></div>
```
Class name bindings can also refer to object values that are found by
traversing a path relative to the view itself:
```javascript
MyView = Ember.View.extend({
classNameBindings: ['messages.empty']
messages: Ember.Object.create({
empty: true
})
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view empty"></div>
```
If you want to add a class name for a property which evaluates to true and
and a different class name if it evaluates to false, you can pass a binding
like this:
```javascript
// Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
Ember.View.create({
classNameBindings: ['isEnabled:enabled:disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view enabled"></div>
```
When isEnabled is `false`, the resulting HTML reprensentation looks like
this:
```html
<div id="ember1" class="ember-view disabled"></div>
```
This syntax offers the convenience to add a class if a property is `false`:
```javascript
// Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
Ember.View.create({
classNameBindings: ['isEnabled::disabled']
isEnabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view"></div>
```
When the `isEnabled` property on the view is set to `false`, it will result
in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view disabled"></div>
```
Updates to the the value of a class name binding will result in automatic
update of the HTML `class` attribute in the view's rendered HTML
representation. If the value becomes `false` or `undefined` the class name
will be removed.
Both `classNames` and `classNameBindings` are concatenated properties. See
`Ember.Object` documentation for more information about concatenated
properties.
## HTML Attributes
The HTML attribute section of a view's tag can be set by providing an
`attributeBindings` property set to an array of property names on the view.
The return value of these properties will be used as the value of the view's
HTML associated attribute:
```javascript
AnchorView = Ember.View.extend({
tagName: 'a',
attributeBindings: ['href'],
href: 'http://google.com'
});
```
Will result in view instances with an HTML representation of:
```html
<a id="ember1" class="ember-view" href="http://google.com"></a>
```
If the return value of an `attributeBindings` monitored property is a boolean
the property will follow HTML's pattern of repeating the attribute's name as
its value:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: true
});
```
Will result in view instances with an HTML representation of:
```html
<input id="ember1" class="ember-view" disabled="disabled" />
```
`attributeBindings` can refer to computed properties:
```javascript
MyTextInput = Ember.View.extend({
tagName: 'input',
attributeBindings: ['disabled'],
disabled: function(){
if (someLogic) {
return true;
} else {
return false;
}
}.property()
});
```
Updates to the the property of an attribute binding will result in automatic
update of the HTML attribute in the view's rendered HTML representation.
`attributeBindings` is a concatenated property. See `Ember.Object`
documentation for more information about concatenated properties.
## Templates
The HTML contents of a view's rendered representation are determined by its
template. Templates can be any function that accepts an optional context
parameter and returns a string of HTML that will be inserted within the
view's tag. Most typically in Ember this function will be a compiled
`Ember.Handlebars` template.
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('I am the template')
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I am the template</div>
```
Within an Ember application is more common to define a Handlebars templates as
part of a page:
```html
<script type='text/x-handlebars' data-template-name='some-template'>
Hello
</script>
```
And associate it by name using a view's `templateName` property:
```javascript
AView = Ember.View.extend({
templateName: 'some-template'
});
```
Using a value for `templateName` that does not have a Handlebars template
with a matching `data-template-name` attribute will throw an error.
Assigning a value to both `template` and `templateName` properties will throw
an error.
For views classes that may have a template later defined (e.g. as the block
portion of a `{{view}}` Handlebars helper call in another template or in
a subclass), you can provide a `defaultTemplate` property set to compiled
template function. If a template is not later provided for the view instance
the `defaultTemplate` value will be used:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default'),
template: null,
templateName: null
});
```
Will result in instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">I was the default</div>
```
If a `template` or `templateName` is provided it will take precedence over
`defaultTemplate`:
```javascript
AView = Ember.View.extend({
defaultTemplate: Ember.Handlebars.compile('I was the default')
});
aView = AView.create({
template: Ember.Handlebars.compile('I was the template, not default')
});
```
Will result in the following HTML representation when rendered:
```html
<div id="ember1" class="ember-view">I was the template, not default</div>
```
## View Context
The default context of the compiled template is the view's controller:
```javascript
AView = Ember.View.extend({
template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
});
aController = Ember.Object.create({
firstName: 'Barry',
excitedGreeting: function(){
return this.get("content.firstName") + "!!!"
}.property()
});
aView = AView.create({
controller: aController,
});
```
Will result in an HTML representation of:
```html
<div id="ember1" class="ember-view">Hello Barry!!!</div>
```
A context can also be explicitly supplied through the view's `context`
property. If the view has neither `context` nor `controller` properties, the
`parentView`'s context will be used.
## Layouts
Views can have a secondary template that wraps their main template. Like
primary templates, layouts can be any function that accepts an optional
context parameter and returns a string of HTML that will be inserted inside
view's tag. Views whose HTML element is self closing (e.g. `<input />`)
cannot have a layout and this property will be ignored.
Most typically in Ember a layout will be a compiled `Ember.Handlebars`
template.
A view's layout can be set directly with the `layout` property or reference
an existing Handlebars template by name with the `layoutName` property.
A template used as a layout must contain a single use of the Handlebars
`{{yield}}` helper. The HTML contents of a view's rendered `template` will be
inserted at this location:
```javascript
AViewWithLayout = Ember.View.extend({
layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
template: Ember.Handlebars.compile("I got wrapped"),
});
```
Will result in view instances with an HTML representation of:
```html
<div id="ember1" class="ember-view">
<div class="my-decorative-class">
I got wrapped
</div>
</div>
```
See `Handlebars.helpers.yield` for more information.
## Responding to Browser Events
Views can respond to user-initiated events in one of three ways: method
implementation, through an event manager, and through `{{action}}` helper use
in their template or layout.
### Method Implementation
Views can respond to user-initiated events by implementing a method that
matches the event name. A `jQuery.Event` object will be passed as the
argument to this method.
```javascript
AView = Ember.View.extend({
click: function(event){
// will be called when when an instance's
// rendered element is clicked
}
});
```
### Event Managers
Views can define an object as their `eventManager` property. This object can
then implement methods that match the desired event names. Matching events
that occur on the view's rendered HTML or the rendered HTML of any of its DOM
descendants will trigger this method. A `jQuery.Event` object will be passed
as the first argument to the method and an `Ember.View` object as the
second. The `Ember.View` will be the view whose rendered HTML was interacted
with. This may be the view with the `eventManager` property or one of its
descendent views.
```javascript
AView = Ember.View.extend({
eventManager: Ember.Object.create({
doubleClick: function(event, view){
// will be called when when an instance's
// rendered element or any rendering
// of this views's descendent
// elements is clicked
}
})
});
```
An event defined for an event manager takes precedence over events of the
same name handled through methods on the view.
```javascript
AView = Ember.View.extend({
mouseEnter: function(event){
// will never trigger.
},
eventManager: Ember.Object.create({
mouseEnter: function(event, view){
// takes presedence over AView#mouseEnter
}
})
});
```
Similarly a view's event manager will take precedence for events of any views
rendered as a descendent. A method name that matches an event name will not
be called if the view instance was rendered inside the HTML representation of
a view that has an `eventManager` property defined that handles events of the
name. Events not handled by the event manager will still trigger method calls
on the descendent.
```javascript
OuterView = Ember.View.extend({
template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
eventManager: Ember.Object.create({
mouseEnter: function(event, view){
// view might be instance of either
// OuterView or InnerView depending on
// where on the page the user interaction occured
}
})
});
InnerView = Ember.View.extend({
click: function(event){
// will be called if rendered inside
// an OuterView because OuterView's
// eventManager doesn't handle click events
},
mouseEnter: function(event){
// will never be called if rendered inside
// an OuterView.
}
});
```
### Handlebars `{{action}}` Helper
See `Handlebars.helpers.action`.
### Event Names
All of the event handling approaches described above respond to the same set
of events. The names of the built-in events are listed below. (The hash of
built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
can be registered by using `Ember.Application.customEvents`.
Touch events:
* `touchStart`
* `touchMove`
* `touchEnd`
* `touchCancel`
Keyboard events
* `keyDown`
* `keyUp`
* `keyPress`
Mouse events
* `mouseDown`
* `mouseUp`
* `contextMenu`
* `click`
* `doubleClick`
* `mouseMove`
* `focusIn`
* `focusOut`
* `mouseEnter`
* `mouseLeave`
Form events:
* `submit`
* `change`
* `focusIn`
* `focusOut`
* `input`
HTML5 drag and drop events:
* `dragStart`
* `drag`
* `dragEnter`
* `dragLeave`
* `drop`
* `dragEnd`
## Handlebars `{{view}}` Helper
Other `Ember.View` instances can be included as part of a view's template by
using the `{{view}}` Handlebars helper. See `Handlebars.helpers.view` for
additional information.

/**
A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
allowing programatic management of its child views.
## Setting Initial Child Views
The initial array of child views can be set in one of two ways. You can
provide a `childViews` property at creation time that contains instance of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: [Ember.View.create(), Ember.View.create()]
});
```
You can also provide a list of property names whose values are instances of
`Ember.View`:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', 'bView', 'cView'],
aView: Ember.View.create(),
bView: Ember.View.create(),
cView: Ember.View.create()
});
```
The two strategies can be combined:
```javascript
aContainer = Ember.ContainerView.create({
childViews: ['aView', Ember.View.create()],
aView: Ember.View.create()
});
```
Each child view's rendering will be inserted into the container's rendered
HTML in the same order as its position in the `childViews` property.
## Adding and Removing Child Views
The container view implements `Ember.MutableArray` allowing programatic management of its child views.
To remove a view, pass that view into a `removeObject` call on the container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Removing a view
```javascript
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.removeObject(aContainer.get('bView'));
aContainer.toArray(); // [aContainer.aView]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
</div>
```
Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
container view.
Given an empty `<body>` the following code
```javascript
aContainer = Ember.ContainerView.create({
classNames: ['the-container'],
childViews: ['aView', 'bView'],
aView: Ember.View.create({
template: Ember.Handlebars.compile("A")
}),
bView: Ember.View.create({
template: Ember.Handlebars.compile("B")
})
});
aContainer.appendTo('body');
```
Results in the HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
</div>
```
Adding a view
```javascript
AnotherViewClass = Ember.View.extend({
template: Ember.Handlebars.compile("Another view")
});
aContainer.toArray(); // [aContainer.aView, aContainer.bView]
aContainer.pushObject(AnotherViewClass.create());
aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
```
Will result in the following HTML
```html
<div class="ember-view the-container">
<div class="ember-view">A</div>
<div class="ember-view">B</div>
<div class="ember-view">Another view</div>
</div>
```
## Templates and Layout
A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
`defaultLayout` property on a container view will not result in the template
or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
representation will only be the rendered HTML of its child views.
## Binding a View to Display
If you would like to display a single view in your ContainerView, you can set
its `currentView` property. When the `currentView` property is set to a view
instance, it will be added to the ContainerView. If the `currentView` property
is later changed to a different view, the new view will replace the old view.
If `currentView` is set to `null`, the last `currentView` will be removed.
This functionality is useful for cases where you want to bind the display of
a ContainerView to a controller or state manager. For example, you can bind
the `currentView` of a container to a controller like this:
```javascript
App.appController = Ember.Object.create({
view: Ember.View.create({
templateName: 'person_template'
})
});
```
```handlebars
{{view Ember.ContainerView currentViewBinding="App.appController.view"}}
```

/**
`Ember.CollectionView` is an `Ember.View` descendent responsible for managing
a collection (an array or array-like object) by maintaining a child view object
and associated DOM representation for each item in the array and ensuring
that child views and their associated rendered HTML are updated when items in
the array are added, removed, or replaced.
## Setting content
The managed collection of objects is referenced as the `Ember.CollectionView`
instance's `content` property.
```javascript
someItemsView = Ember.CollectionView.create({
content: ['A', 'B','C']
})
```
The view for each item in the collection will have its `content` property set
to the item.
## Specifying itemViewClass
By default the view class for each item in the managed collection will be an
instance of `Ember.View`. You can supply a different class by setting the
`CollectionView`'s `itemViewClass` property.
Given an empty `<body>` and the following code:
```javascript
someItemsView = Ember.CollectionView.create({
classNames: ['a-collection'],
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
someItemsView.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view a-collection">
<div class="ember-view">the letter: A</div>
<div class="ember-view">the letter: B</div>
<div class="ember-view">the letter: C</div>
</div>
```
## Automatic matching of parent/child tagNames
Setting the `tagName` property of a `CollectionView` to any of
"ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
in the item views receiving an appropriately matched `tagName` property.
Given an empty `<body>` and the following code:
```javascript
anUndorderedListView = Ember.CollectionView.create({
tagName: 'ul',
content: ['A','B','C'],
itemViewClass: Ember.View.extend({
template: Ember.Handlebars.compile("the letter: {{view.content}}")
})
});
anUndorderedListView.appendTo('body');
```
Will result in the following HTML structure
```html
<ul class="ember-view a-collection">
<li class="ember-view">the letter: A</li>
<li class="ember-view">the letter: B</li>
<li class="ember-view">the letter: C</li>
</ul>
```
Additional `tagName` pairs can be provided by adding to
`Ember.CollectionView.CONTAINER_MAP `
```javascript
Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
```
## Programatic creation of child views
For cases where additional customization beyond the use of a single
`itemViewClass` or `tagName` matching is required CollectionView's
`createChildView` method can be overidden:
```javascript
CustomCollectionView = Ember.CollectionView.extend({
createChildView: function(viewClass, attrs) {
if (attrs.content.kind == 'album') {
viewClass = App.AlbumView;
} else {
viewClass = App.SongView;
}
return this._super(viewClass, attrs);
}
});
```
## Empty View
You can provide an `Ember.View` subclass to the `Ember.CollectionView`
instance as its `emptyView` property. If the `content` property of a
`CollectionView` is set to `null` or an empty array, an instance of this view
will be the `CollectionView`s only child.
```javascript
aListWithNothing = Ember.CollectionView.create({
classNames: ['nothing']
content: null,
emptyView: Ember.View.extend({
template: Ember.Handlebars.compile("The collection is empty")
})
});
aListWithNothing.appendTo('body');
```
Will result in the following HTML structure
```html
<div class="ember-view nothing">
<div class="ember-view">
The collection is empty
</div>
</div>
```
## Adding and Removing items
The `childViews` property of a `CollectionView` should not be directly
manipulated. Instead, add, remove, replace items from its `content` property.
This will trigger appropriate changes to its rendered HTML.
## Use in templates via the `{{collection}}` `Ember.Handlebars` helper
`Ember.Handlebars` provides a helper specifically for adding
`CollectionView`s to templates. See `Ember.Handlebars.collection` for more
details

An `Ember.Component` is a view that is completely
isolated. Property access in its templates go
to the view object and actions are targeted at
the view object. There is no access to the
surrounding context or outer controller; all
contextual information is passed in.
The easiest way to create an `Ember.Component` is via
a template. If you name a template
`controls/my-foo`, you will be able to use
`{{my-foo}}` in other templates, which will make
an instance of the isolated control.
```html
{{app-profile person=currentUser}}
```
```html
<!-- app-profile template -->
<h1>{{person.title}}</h1>
<img {{bindAttr src=person.avatar}}>
<p class='signature'>{{person.signature}}</p>
```
You can also use `yield` inside a template to
include the **contents** of the custom tag:
```html
{{#my-profile person=currentUser}}
<p>Admin mode</p>
{{/my-profile}}
```
```html
<!-- app-profile template -->
<h1>{{person.title}}</h1>
{{yield}} <!-- block contents -->
```
If you want to customize the control, in order to
handle events or actions, you implement a subclass
of `Ember.Component` named after the name of the
control.
For example, you could implement the action
`hello` for the `app-profile` control:
```js
App.AppProfileComponent = Ember.Component.extend({
hello: function(name) {
console.log("Hello", name)
}
});
```
And then use it in the control's template:
```html
<!-- app-profile template -->
<h1>{{person.title}}</h1>
{{yield}} <!-- block contents -->
<button {{action 'hello' person.name}}>
Say Hello to {{person.name}}
</button>
```
Components must have a `-` in their name to avoid
conflicts with built-in controls that wrap HTML
elements. This is consistent with the same
requirement in web components.

`Ember.ViewTargetActionSupport` is a mixin that can be included in a
view class to add a `triggerAction` method with semantics similar to
the Handlebars `{{action}}` helper. It provides intelligent defaults
for the action's target: the view's controller; and the context that is
sent with the action: the view's context.
Note: In normal Ember usage, the `{{action}}` helper is usually the best
choice. This mixin is most often useful when you are doing more complex
event handling in custom View subclasses.
For example:
```javascript
App.SaveButtonView = Ember.View.extend(Ember.ViewTargetActionSupport, {
action: 'save',
click: function(){
this.triggerAction(); // Sends the `save` action, along with the current context

Register a bound helper or custom view helper.

```javascript

The above bound helper can be used inside of templates as follows:

In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
For more examples of bound helpers, see documentation for
`Ember.Handlebars.registerBoundHelper`.
## Custom view helper example
Assuming a view subclass named `App.CalenderView` were defined, a helper
for rendering instances of this view could be registered as follows:
```javascript
Ember.Handlebars.helper('calendar', App.CalendarView):
```
The above bound helper can be used inside of templates as follows:

{{calendar}}

/**
Register a bound handlebars helper. Bound helpers behave similarly to regular
handlebars helpers, with the added ability to re-render when the underlying data
changes.
## Simple example
```javascript
Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
return value.toUpperCase();
});
```
The above bound helper can be used inside of templates as follows:
```handlebars
{{capitalize name}}
```
In this case, when the `name` property of the template's context changes,
the rendered value of the helper will update to reflect this change.
## Example with options
Like normal handlebars helpers, bound helpers have access to the options
passed into the helper call.
```javascript
Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
var count = options.hash.count;
var a = [];
while(a.length < count){
a.push(value);
}
return a.join('');
});
```
This helper could be used in a template as follows:
```handlebars
{{repeat text count=3}}
```
## Example with bound options
Bound hash options are also supported. Example:
```handlebars
{{repeat text countBinding="numRepeats"}}
```
In this example, count will be bound to the value of
the `numRepeats` property on the context. If that property
changes, the helper will be re-rendered.
## Example with extra dependencies
The `Ember.Handlebars.registerBoundHelper` method takes a variable length
third parameter which indicates extra dependencies on the passed in value.
This allows the handlebars helper to update when these dependencies change.
```javascript
Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
return value.get('name').toUpperCase();
}, 'name');
```
## Example with multiple bound properties
`Ember.Handlebars.registerBoundHelper` supports binding to
multiple properties, e.g.:
```javascript
Ember.Handlebars.registerBoundHelper('concatenate', function() {
var values = arguments[arguments.length - 1];
return values.join('||');
});
```
Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
`{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
the helpr will re-render. Note that dependency keys cannot be
using in conjunction with multi-property helpers, since it is ambiguous
which property the dependent keys would belong to.
## Use with unbound helper
The `{{unbound}}` helper can be used with bound helper invocations
to render them in their unbound form, e.g.
```handlebars
{{unbound capitalize name}}
```
In this example, if the name property changes, the helper
will not re-render.
## Use with blocks not supported
Bound helpers do not support use with Handlebars blocks or
the addition of child views of any kind.

/**
`bindAttr` allows you to create a binding between DOM element attributes and
Ember objects. For example:
```handlebars
<img {{bindAttr src="imageUrl" alt="imageTitle"}}>
```
The above handlebars template will fill the `<img>`'s `src` attribute will
the value of the property referenced with `"imageUrl"` and its `alt`
attribute with the value of the property referenced with `"imageTitle"`.
If the rendering context of this template is the following object:
```javascript
{
imageUrl: 'http://lolcats.info/haz-a-funny',
imageTitle: 'A humorous image of a cat'
}
```
The resulting HTML output will be:
```html
<img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
```
`bindAttr` cannot redeclare existing DOM element attributes. The use of `src`
in the following `bindAttr` example will be ignored and the hard coded value
of `src="/failwhale.gif"` will take precedence:
```handlebars
<img src="/failwhale.gif" {{bindAttr src="imageUrl" alt="imageTitle"}}>
```
### `bindAttr` and the `class` attribute
`bindAttr` supports a special syntax for handling a number of cases unique
to the `class` DOM element attribute. The `class` attribute combines
multiple discreet values into a single attribute as a space-delimited
list of strings. Each string can be:
* a string return value of an object's property.
* a boolean return value of an object's property
* a hard-coded value
A string return value works identically to other uses of `bindAttr`. The
return value of the property will become the value of the attribute. For
example, the following view and template:
```javascript
AView = Ember.View.extend({
someProperty: function(){
return "aValue";
}.property()
})
```
```handlebars
<img {{bindAttr class="view.someProperty}}>
```
Result in the following rendered output:
```html
<img class="aValue">
```
A boolean return value will insert a specified class name if the property
returns `true` and remove the class name if the property returns `false`.
A class name is provided via the syntax
`somePropertyName:class-name-if-true`.
```javascript
AView = Ember.View.extend({
someBool: true
})
```
```handlebars
<img {{bindAttr class="view.someBool:class-name-if-true"}}>
```
Result in the following rendered output:
```html
<img class="class-name-if-true">
```
An additional section of the binding can be provided if you want to
replace the existing class instead of removing it when the boolean
value changes:
```handlebars
<img {{bindAttr class="view.someBool:class-name-if-true:class-name-if-false"}}>
```
A hard-coded value can be used by prepending `:` to the desired
class name: `:class-name-to-always-apply`.
```handlebars
<img {{bindAttr class=":class-name-to-always-apply"}}>
```
Results in the following rendered output:
```html
<img class="class-name-to-always-apply">
```
All three strategies - string return value, boolean return value, and
hard-coded value – can be combined in a single declaration:
```handlebars
<img {{bindAttr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
```

/**
`{{view}}` inserts a new instance of `Ember.View` into a template passing its
options to the `Ember.View`'s `create` method and using the supplied block as
the view's own template.
An empty `<body>` and the following template:
```handlebars
A span:
{{#view tagName="span"}}
hello.
{{/view}}
```
Will result in HTML structure:
```html
<body>
<!-- Note: the handlebars template script
also results in a rendered Ember.View
which is the outer <div> here -->
<div class="ember-view">
A span:
<span id="ember1" class="ember-view">
Hello.
</span>
</div>
</body>
```
### `parentView` setting
The `parentView` property of the new `Ember.View` instance created through
`{{view}}` will be set to the `Ember.View` instance of the template where
`{{view}}` was called.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
});
aView.appendTo('body');
```
Will result in HTML structure:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view">
my parent: ember1
</div>
</div>
```
### Setting CSS id and class attributes
The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
the `id` option. This option will _not_ be passed to `Ember.View.create`.
```handlebars
{{#view tagName="span" id="a-custom-id"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="a-custom-id" class="ember-view">
hello.
</span>
</div>
```
The HTML `class` attribute can be set on the `{{view}}`'s resulting element
with the `class` or `classNameBindings` options. The `class` option will
directly set the CSS `class` attribute and will not be passed to
`Ember.View.create`. `classNameBindings` will be passed to `create` and use
`Ember.View`'s class name binding functionality:
```handlebars
{{#view tagName="span" class="a-custom-class"}}
hello.
{{/view}}
```
Results in the following HTML structure:
```html
<div class="ember-view">
<span id="ember2" class="ember-view a-custom-class">
hello.
</span>
</div>
```
### Supplying a different view class
`{{view}}` can take an optional first argument before its supplied options to
specify a path to a custom view class.
```handlebars
{{#view "MyApp.CustomView"}}
hello.
{{/view}}
```
The first argument can also be a relative path accessible from the current
context.
```javascript
MyApp = Ember.Application.create({});
MyApp.OuterView = Ember.View.extend({
innerViewClass: Ember.View.extend({
classNames: ['a-custom-view-class-as-property']
}),
template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
});
MyApp.OuterView.create().appendTo('body');
```
Will result in the following HTML:
```html
<div id="ember1" class="ember-view">
<div id="ember2" class="ember-view a-custom-view-class-as-property">
hi
</div>
</div>
```
### Blockless use
If you supply a custom `Ember.View` subclass that specifies its own template
or provide a `templateName` option to `{{view}}` it can be used without
supplying a block. Attempts to use both a `templateName` option and supply a
block will throw an error.
```handlebars
{{view "MyApp.ViewWithATemplateDefined"}}
```
### `viewName` property
You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
will be referenced as a property of its parent view by this name.
```javascript
aView = Ember.View.create({
template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
});
aView.appendTo('body');
aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
```
@method view
@for Ember.Handlebars.helpers

EmberHandlebars.registerHelper('view', function(path, options) {
// If no path is provided, treat path param as options.
if (path && path.data && path.data.isRenderData) {
options = path;
path = "Ember.View";

/**
`{{collection}}` is a `Ember.Handlebars` helper for adding instances of
`Ember.CollectionView` to a template. See `Ember.CollectionView` for
additional information on how a `CollectionView` functions.
`{{collection}}`'s primary use is as a block helper with a `contentBinding`
option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
instance will be created for each item in its `content` property. Each view
will have its own `content` property set to the appropriate item in the
collection.
The provided block will be applied as the template for each item's view.
Given an empty `<body>` the following template:
```handlebars
{{#collection contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
And the following application code
```javascript
App = Ember.Application.create()
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Hi Dave</div>
<div class="ember-view">Hi Mary</div>
<div class="ember-view">Hi Sara</div>
</div>
```
### Blockless Use
If you provide an `itemViewClass` option that has its own `template` you can
omit the block.
The following template:
```handlebars
{{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
```
And application code
```javascript
App = Ember.Application.create();
App.items = [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
];
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Specifying a CollectionView subclass
By default the `{{collection}}` helper will create an instance of
`Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
the helper by passing it as the first argument:
```handlebars
{{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
Hi {{view.content.name}}
{{/collection}}
```
### Forwarded `item.*`-named Options
As with the `{{view}}`, helper options passed to the `{{collection}}` will be
set on the resulting `Ember.CollectionView` as properties. Additionally,
options prefixed with `item` will be applied to the views rendered for each
item (note the camelcasing):
```handlebars
{{#collection contentBinding="App.items"
itemTagName="p"
itemClassNames="greeting"}}
Howdy {{view.content.name}}
{{/collection}}
```
Will result in the following HTML structure:
```html
<div class="ember-view">
<p class="ember-view greeting">Howdy Dave</p>
<p class="ember-view greeting">Howdy Mary</p>
<p class="ember-view greeting">Howdy Sara</p>
</div>

/**
The `{{#each}}` helper loops over elements in a collection, rendering its
block once for each item. It is an extension of the base Handlebars `{{#each}}`
helper:
```javascript
Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
```
```handlebars
{{#each Developers}}
{{name}}
{{/each}}
```
`{{each}}` supports an alternative syntax with element naming:
```handlebars
{{#each person in Developers}}
{{person.name}}
{{/each}}
```
When looping over objects that do not have properties, `{{this}}` can be used
to render the object:
```javascript
DeveloperNames = ['Yehuda', 'Tom', 'Paul']
```
```handlebars
{{#each DeveloperNames}}
{{this}}
{{/each}}
```
### {{else}} condition
`{{#each}}` can have a matching `{{else}}`. The contents of this block will render
if the collection is empty.
```
{{#each person in Developers}}
{{person.name}}
{{else}}
<p>Sorry, nobody is available for this task.</p>
{{/each}}
```
### Specifying a View class for items
If you provide an `itemViewClass` option that references a view class
with its own `template` you can omit the block.
The following template:
```handlebars
{{#view App.MyView }}
{{each view.items itemViewClass="App.AnItemView"}}
{{/view}}
```
And application code
```javascript
App = Ember.Application.create({
MyView: Ember.View.extend({
items: [
Ember.Object.create({name: 'Dave'}),
Ember.Object.create({name: 'Mary'}),
Ember.Object.create({name: 'Sara'})
]
})
});
App.AnItemView = Ember.View.extend({
template: Ember.Handlebars.compile("Greetings {{name}}")
});
```
Will result in the HTML structure below
```html
<div class="ember-view">
<div class="ember-view">Greetings Dave</div>
<div class="ember-view">Greetings Mary</div>
<div class="ember-view">Greetings Sara</div>
</div>
```
### Representing each item with a Controller.
By default the controller lookup within an `{{#each}}` block will be
the controller of the template where the `{{#each}}` was used. If each
item needs to be presented by a custom controller you can provide a
`itemController` option which references a controller by lookup name.
Each item in the loop will be wrapped in an instance of this controller
and the item itself will be set to the `content` property of that controller.
This is useful in cases where properties of model objects need transformation
or synthesis for display:
```javascript
App.DeveloperController = Ember.ObjectController.extend({
isAvailableForHire: function(){
return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
}.property('isEmployed', 'isSeekingWork')
})
```
```handlebars
{{#each person in developers itemController="developer"}}
{{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
{{/each}}
```
Each itemController will receive a reference to the current controller as
a `parentController` property.

`template` allows you to render a template from inside another template.
This allows you to re-use the same template in multiple places. For example:

{{#with loggedInUser}}
Last Login: {{lastLogin}}
User Info: {{template "user_info"}}

/**
The `Ember.Select` view class renders a
[select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
allowing the user to choose from a list of options.
The text and `value` property of each `<option>` element within the
`<select>` element are populated from the objects in the `Element.Select`'s
`content` property. The underlying data object of the selected `<option>` is
stored in the `Element.Select`'s `value` property.
### `content` as an array of Strings
The simplest version of an `Ember.Select` takes an array of strings as its
`content` property. The string will be used as both the `value` property and
the inner text of each `<option>` element inside the rendered `<select>`.
Example:
```javascript
App.names = ["Yehuda", "Tom"];
```
```handlebars
{{view Ember.Select contentBinding="App.names"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
You can control which `<option>` is selected through the `Ember.Select`'s
`value` property directly or as a binding:
```javascript
App.names = Ember.Object.create({
selected: 'Tom',
content: ["Yehuda", "Tom"]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.names.content"
valueBinding="App.names.selected"
}}
```
Would result in the following HTML with the `<option>` for 'Tom' selected:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom" selected="selected">Tom</option>
</select>
```
A user interacting with the rendered `<select>` to choose "Yehuda" would
update the value of `App.names.selected` to "Yehuda".
### `content` as an Array of Objects
An `Ember.Select` can also take an array of JavaScript or Ember objects as
its `content` property.
When using objects you need to tell the `Ember.Select` which property should
be accessed on each object to supply the `value` attribute of the `<option>`
and which property should be used to supply the element text.
The `optionValuePath` option is used to specify the path on each object to
the desired property for the `value` attribute. The `optionLabelPath`
specifies the path on each object to the desired property for the
element's text. Both paths must reference each object itself as `content`:
```javascript
App.programmers = [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
];
```
```handlebars
{{view Ember.Select
contentBinding="App.programmers"
optionValuePath="content.id"
optionLabelPath="content.firstName"}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2">Tom</option>
</select>
```
The `value` attribute of the selected `<option>` within an `Ember.Select`
can be bound to a property on another object by providing a
`valueBinding` option:
```javascript
App.programmers = [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
];
App.currentProgrammer = Ember.Object.create({
id: 2
});
```
```handlebars
{{view Ember.Select
contentBinding="App.programmers"
optionValuePath="content.id"
optionLabelPath="content.firstName"
valueBinding="App.currentProgrammer.id"}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `id` value of `App.currentProgrammer`
to match the `value` property of the newly selected `<option>`.
Alternatively, you can control selection through the underlying objects
used to render each object providing a `selectionBinding`. When the selected
`<option>` is changed, the property path provided to `selectionBinding`
will be updated to match the content object of the rendered `<option>`
element:
```javascript
App.controller = Ember.Object.create({
selectedPerson: null,
content: [
Ember.Object.create({firstName: "Yehuda", id: 1}),
Ember.Object.create({firstName: "Tom", id: 2})
]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.controller.content"
optionValuePath="content.id"
optionLabelPath="content.firstName"
selectionBinding="App.controller.selectedPerson"}}
```
Would result in the following HTML with a selected option:
```html
<select class="ember-select">
<option value="1">Yehuda</option>
<option value="2" selected="selected">Tom</option>
</select>
```
Interacting with the rendered element by selecting the first option
('Yehuda') will update the `selectedPerson` value of `App.controller`
to match the content object of the newly selected `<option>`. In this
case it is the first object in the `App.controller.content`
### Supplying a Prompt
A `null` value for the `Ember.Select`'s `value` or `selection` property
results in there being no `<option>` with a `selected` attribute:
```javascript
App.controller = Ember.Object.create({
selected: null,
content: [
"Yehuda",
"Tom"
]
});
```
``` handlebars
{{view Ember.Select
contentBinding="App.controller.content"
valueBinding="App.controller.selected"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```
Although `App.controller.selected` is `null` and no `<option>`
has a `selected` attribute the rendered HTML will display the
first item as though it were selected. You can supply a string
value for the `Ember.Select` to display when there is no selection
with the `prompt` option:
```javascript
App.controller = Ember.Object.create({
selected: null,
content: [
"Yehuda",
"Tom"
]
});
```
```handlebars
{{view Ember.Select
contentBinding="App.controller.content"
valueBinding="App.controller.selected"
prompt="Please select a name"
}}
```
Would result in the following HTML:
```html
<select class="ember-select">
<option>Please select a name</option>
<option value="Yehuda">Yehuda</option>
<option value="Tom">Tom</option>
</select>
```

/**
The collection of functions, keyed by name, available on this route as
action targets.
These functions will be invoked when a matching `{{action}}` is triggered
from within a template and the application's current route is this route.
Events can also be invoked from other parts of your application via `Route#send`
or `Controller#send`.
The context of the event will be this route.
## Bubbling
By default, an event will stop bubbling once a handler defined
on the `events` hash handles it. To continue bubbling the event,
you must return `true` from the handler.
## Built-in events
There are a few built-in events pertaining to transitions that you
can use to customize transition behavior: `willTransition` and
`error`.
### `willTransition`
The `willTransition` event is fired at the beginning of any
attempted transition with a `Transition` object as the sole
argument. This event can be used for aborting, redirecting,
or decorating the transition from the currently active routes.
A good example is preventing navigation when a form is
half-filled out:
```js
App.ContactFormRoute = Ember.Route.extend({
events: {
willTransition: function(transition) {
if (this.controller.get('userHasEnteredData')) {
this.controller.displayNavigationConfirm();
transition.abort();
}
}
}
});
```
You can also redirect elsewhere by calling
`this.transitionTo('elsewhere')` from within `willTransition`.
Note that `willTransition` will not be fired for the
redirecting `transitionTo`, since `willTransition` doesn't
fire when there is already a transition underway. If you want
subsequent `willTransition` events to fire for the redirecting
transition, you must first explicitly call
`transition.abort()`.
### `error`
When attempting to transition into a route, any of the hooks
may throw an error, or return a promise that rejects, at which
point an `error` event will be fired on the partially-entered
routes, allowing for per-route error handling logic, or shared
error handling logic defined on a parent route.
Here is an example of an error handler that will be invoked
for rejected promises / thrown errors from the various hooks
on the route, as well as any unhandled errors from child
routes:
```js
App.AdminRoute = Ember.Route.extend({
beforeModel: function() {
throw "bad things!";
// ...or, equivalently:
return Ember.RSVP.reject("bad things!");
},
events: {
error: function(error, transition) {
// Assuming we got here due to the error in `beforeModel`,
// we can expect that error === "bad things!",
// but a promise model rejecting would also
// call this hook, as would any errors encountered
// in `afterModel`.
// The `error` hook is also provided the failed
// `transition`, which can be stored and later
// `.retry()`d if desired.
this.transitionTo('login');
}
}
});
```
`error` events that bubble up all the way to `ApplicationRoute`
will fire a default error handler that logs the error. You can
specify your own global default error handler by overriding the
`error` handler on `ApplicationRoute`:
```js
App.ApplicationRoute = Ember.Route.extend({
events: {
error: function(error, transition) {
this.controllerFor('banner').displayError(error.message);
}
}
});

*/
redirect: Ember.K,
/**
This hook is the first of the route entry validation hooks
called when an attempt is made to transition into a route
or one of its children. It is called before `model` and
`afterModel`, and is appropriate for cases when:
1) A decision can be made to redirect elsewhere without
needing to resolve the model first.
2) Any async operations need to occur first before the
model is attempted to be resolved.
This hook is provided the current `transition` attempt
as a parameter, which can be used to `.abort()` the transition,
save it for a later `.retry()`, or retrieve values set
on it from a previous hook. You can also just call
`this.transitionTo` to another route to implicitly
abort the `transition`.
You can return a promise from this hook to pause the
transition until the promise resolves (or rejects). This could
be useful, for instance, for retrieving async code from
the server that is required to enter a route.
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
return Ember.$.getScript('/models/post.js');
}
}
});
```
If `App.Post` doesn't exist in the above example,
`beforeModel` will use jQuery's `getScript`, which
returns a promise that resolves after the server has
successfully retrieved and executed the code from the
server. Note that if an error were to occur, it would
be passed to the `error` hook on `Ember.Route`, but
it's also possible to handle errors specific to
`beforeModel` right from within the hook (to distinguish
from the shared error handling behavior of the `error`
hook):
```js
App.PostRoute = Ember.Route.extend({
beforeModel: function(transition) {
if (!App.Post) {
var self = this;
return Ember.$.getScript('post.js').then(null, function(e) {
self.transitionTo('help');
// Note that the above transitionTo will implicitly
// halt the transition. If you were to return
// nothing from this promise reject handler,
// according to promise semantics, that would
// convert the reject into a resolve and the
// transition would continue. To propagate the
// error so that it'd be handled by the `error`
// hook, you would have to either
return Ember.RSVP.reject(e);
// or
throw e;
});
}
}
});
```
@param {Transition} transition
@return {Promise} if the value returned from this hook is
a promise, the transition will pause until the transition
resolves. Otherwise, non-promise return values are not
utilized in any way.
*/

/**

A hook you can implement to convert the URL into the model for
this route.
```js
App.Router.map(function() {
this.resource('post', {path: '/posts/:post_id'});
});
```
The model for the `post` route is `App.Post.find(params.post_id)`.
By default, if your route has a dynamic segment ending in `_id`:
* The model class is determined from the segment (`post_id`'s
class is `App.Post`)
* The find method is called on the model class with the value of
the dynamic segment.
Note that for routes with dynamic segments, this hook is only
executed when entered via the URL. If the route is entered
through a transition (e.g. when using the `linkTo` Handlebars
helper), then a model context is already provided and this hook
is not called. Routes without dynamic segments will always
execute the model hook.
This hook follows the asynchronous/promise semantics
described in the documentation for `beforeModel`. In particular,
if a promise returned from `model` fails, the error will be
handled by the `error` hook on `Ember.Route`.

This means that your template will get a proxy for the model as its

As an example, consider the router:

The name of the `PostRoute`, as defined by the router, is `post`.
By default, render will:

outlet: 'detail', // the name of the outlet in that template
controller: 'blogPost' // the controller to use for the template
});

/**
The `{{linkTo}}` helper renders a link to the supplied
`routeName` passing an optionally supplied model to the
route as its `model` context of the route. The block
for `{{linkTo}}` becomes the innerHTML of the rendered
element:
```handlebars
{{#linkTo photoGallery}}
Great Hamster Photos
{{/linkTo}}
```
```html
<a href="/hamster-photos">
Great Hamster Photos
</a>
```
### Supplying a tagName
By default `{{linkTo}}` renders an `<a>` element. This can
be overridden for a single use of `{{linkTo}}` by supplying
a `tagName` option:
```handlebars
{{#linkTo photoGallery tagName="li"}}
Great Hamster Photos
{{/linkTo}}
```
```html
<li>
Great Hamster Photos
</li>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Handling `href`
`{{linkTo}}` will use your application's Router to
fill the element's `href` property with a url that
matches the path to the supplied `routeName` for your
routers's configured `Location` scheme, which defaults
to Ember.HashLocation.
### Handling current route
`{{linkTo}}` will apply a CSS class name of 'active'
when the application's current route matches
the supplied routeName. For example, if the application's
current route is 'photoGallery.recent' the following
use of `{{linkTo}}`:
```handlebars
{{#linkTo photoGallery.recent}}
Great Hamster Photos from the last week
{{/linkTo}}
```
will result in
```html
<a href="/hamster-photos/this-week" class="active">
Great Hamster Photos
</a>
```
The CSS class name used for active classes can be customized
for a single use of `{{linkTo}}` by passing an `activeClass`
option:
```handlebars
{{#linkTo photoGallery.recent activeClass="current-url"}}
Great Hamster Photos from the last week
{{/linkTo}}
```
```html
<a href="/hamster-photos/this-week" class="current-url">
Great Hamster Photos
</a>
```
To override this option for your entire application, see
"Overriding Application-wide Defaults".
### Supplying a model
An optional model argument can be used for routes whose
paths contain dynamic segments. This argument will become
the model context of the linked route:
```javascript
App.Router.map(function(){
this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
})
```
```handlebars
{{#linkTo photoGallery aPhoto}}
{{aPhoto.title}}
{{/linkTo}}
```
```html
<a href="/hamster-photos/42">
Tomster
</a>
```
### Supplying multiple models
For deep-linking to route paths that contain multiple
dynamic segments, multiple model arguments can be used.
As the router transitions through the route path, each
supplied model argument will become the context for the
route with the dynamic segments:
```javascript
App.Router.map(function(){
this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function(){
this.route("comment", {path: "comments/:comment_id"});
});
});
```
This argument will become the model context of the linked route:
```handlebars
{{#linkTo photoGallery.comment aPhoto comment}}
{{comment.body}}
{{/linkTo}}
```
```html
<a href="/hamster-photos/42/comment/718">
A+++ would snuggle again.
</a>
```
### Overriding Application-wide Defaults
``{{linkTo}}`` creates an instance of Ember.LinkView
for rendering. To override options for your entire
application, reopen Ember.LinkView and supply the
desired values:
``` javascript
Ember.LinkView.reopen({
activeClass: "is-active",
tagName: 'li'
})
```
It is also possible to override the default event in
this manner:
``` javascript
Ember.LinkView.reopen({
eventName: 'customEventName'
});
```

The `outlet` helper is a placeholder that the router will fill in with

``` handlebars

```
By default, a template based on Ember's naming conventions will be rendered
into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
You can render a different template by using the `render()` method in the
route's `renderTemplate` hook. The following will render the `favoritePost`
template into the `outlet`.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost');
}
});
```
You can create custom named outlets for more control.
``` handlebars
{{outlet favoritePost}}
{{outlet posts}}
```
Then you can define what template is rendered into each outlet in your
route.
``` javascript
App.PostsRoute = Ember.Route.extend({
renderTemplate: function() {
this.render('favoritePost', { outlet: 'favoritePost' });
this.render('posts', { outlet: 'posts' });
}
});

You can specify the view class that the outlet uses to contain and manage the
templates rendered into it.

{{outlet viewClass=App.SectionContainer}}

tagName: 'section',

/**
The `{{action}}` helper registers an HTML element within a template for DOM
event handling and forwards that interaction to the view's controller
or supplied `target` option (see 'Specifying a Target').
If the view's controller does not implement the event, the event is sent
to the current route, and it bubbles up the route hierarchy from there.
User interaction with that element will invoke the supplied action name on
the appropriate target.
Given the following Handlebars template on the page
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName}}>
click me
</div>
</script>
```
And application code
```javascript
AController = Ember.Controller.extend({
anActionName: function() {}
});
AView = Ember.View.extend({
controller: AController.create(),
templateName: 'a-template'
});
aView = AView.create();
aView.appendTo('body');
```
Will result in the following rendered HTML
```html
<div class="ember-view">
<div data-ember-action="1">
click me
</div>
</div>
```
Clicking "click me" will trigger the `anActionName` method of the
`AController`. In this case, no additional parameters will be passed.
If you provide additional parameters to the helper:
```handlebars
<button {{action 'edit' post}}>Edit</button>
```
Those parameters will be passed along as arguments to the JavaScript
function implementing the action.
### Event Propagation
Events triggered through the action helper will automatically have
`.preventDefault()` called on them. You do not need to do so in your event
handlers.
To also disable bubbling, pass `bubbles=false` to the helper:
```handlebars
<button {{action 'edit' post bubbles=false}}>Edit</button>
```
If you need the default handler to trigger you should either register your
own event handler, or use event methods on your view class. See `Ember.View`
'Responding to Browser Events' for more information.
### Specifying DOM event type
By default the `{{action}}` helper registers for DOM `click` events. You can
supply an `on` option to the helper to specify a different DOM event name:
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName on="doubleClick"}}>
click me
</div>
</script>
```
See `Ember.View` 'Responding to Browser Events' for a list of
acceptable DOM event names.
NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
only function if an `Ember.EventDispatcher` instance is available. An
`Ember.EventDispatcher` instance will be created when a new `Ember.Application`
is created. Having an instance of `Ember.Application` will satisfy this
requirement.
### Specifying whitelisted modifier keys
By default the `{{action}}` helper will ignore click event with pressed modifier
keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName allowedKeys="alt"}}>
click me
</div>
</script>
```
This way the `{{action}}` will fire when clicking with the alt key pressed down.
### Specifying a Target
There are several possible target objects for `{{action}}` helpers:
In a typical Ember application, where views are managed through use of the
`{{outlet}}` helper, actions will bubble to the current controller, then
to the current route, and then up the route hierarchy.
Alternatively, a `target` option can be provided to the helper to change
which object will receive the method call. This option must be a path
to an object, accessible in the current context:
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action anActionName target="MyApplication.someObject"}}>
click me
</div>
</script>
```
Clicking "click me" in the rendered HTML of the above template will trigger
the `anActionName` method of the object at `MyApplication.someObject`.
If an action's target does not implement a method that matches the supplied
action name an error will be thrown.
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
<div {{action aMethodNameThatIsMissing}}>
click me
</div>
</script>
```
With the following application code
```javascript
AView = Ember.View.extend({
templateName; 'a-template',
// note: no method 'aMethodNameThatIsMissing'
anActionName: function(event) {}
});
aView = AView.create();
aView.appendTo('body');
```
Will throw `Uncaught TypeError: Cannot call method 'call' of undefined` when
"click me" is clicked.
### Additional Parameters
You may specify additional parameters to the `{{action}}` helper. These
parameters are passed along as the arguments to the JavaScript function
implementing the action.
```handlebars
<script type="text/x-handlebars" data-template-name='a-template'>
{{#each person in people}}
<div {{action edit person}}>
click me
</div>
{{/each}}
</script>
```
Clicking "click me" will trigger the `edit` method on the current view's
controller with the current person as a parameter.

The DefaultResolver defines the default lookup rules to resolve
container lookups before consulting the container for registered
items:
* templates are looked up on `Ember.TEMPLATES`
* other names are looked up on the application after converting
the name. For example, `controller:post` looks up
`App.PostController` by default.
* there are some nuances (see examples below)
### How Resolving Works
The container calls this object's `resolve` method with the
`fullName` argument.
It first parses the fullName into an object using `parseName`.
Then it checks for the presence of a type-specific instance
method of the form `resolve[Type]` and calls it if it exists.
For example if it was resolving 'template:post', it would call
the `resolveTemplate` method.
Its last resort is to call the `resolveOther` method.
The methods of this object are designed to be easy to override
in a subclass. For example, you could enhance how a template
is resolved like so:
```javascript
App = Ember.Application.create({
resolver: Ember.DefaultResolver.extend({
resolveTemplate: function(parsedName) {
var resolvedTemplate = this._super(parsedName);
if (resolvedTemplate) { return resolvedTemplate; }
return Ember.TEMPLATES['not_found'];
}
})
});
```
Some examples of how names are resolved:
```
'template:post' //=> Ember.TEMPLATES['post']
'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
'template:blogPost' //=> Ember.TEMPLATES['blogPost']
// OR
// Ember.TEMPLATES['blog_post']
'controller:post' //=> App.PostController
'controller:posts.index' //=> App.PostsIndexController
'controller:blog/post' //=> Blog.PostController
'controller:basic' //=> Ember.Controller
'route:post' //=> App.PostRoute
'route:posts.index' //=> App.PostsIndexRoute
'route:blog/post' //=> Blog.PostRoute
'route:basic' //=> Ember.Route
'view:post' //=> App.PostView
'view:posts.index' //=> App.PostsIndexView
'view:blog/post' //=> Blog.PostView
'view:basic' //=> Ember.View
'foo:post' //=> App.PostFoo

/**
An instance of `Ember.Application` is the starting point for every Ember
application. It helps to instantiate, initialize and coordinate the many
objects that make up your app.
Each Ember app has one and only one `Ember.Application` object. In fact, the
very first thing you should do in your application is create the instance:
```javascript
window.App = Ember.Application.create();
```
Typically, the application object is the only global variable. All other
classes in your app should be properties on the `Ember.Application` instance,
which highlights its first role: a global namespace.
For example, if you define a view class, it might look like this:
```javascript
App.MyView = Ember.View.extend();
```
By default, calling `Ember.Application.create()` will automatically initialize
your application by calling the `Ember.Application.initialize()` method. If
you need to delay initialization, you can call your app's `deferReadiness()`
method. When you are ready for your app to be initialized, call its
`advanceReadiness()` method.
You can define a `ready` method on the `Ember.Application` instance, which
will be run by Ember when the application is initialized.
Because `Ember.Application` inherits from `Ember.Namespace`, any classes
you create will have useful string representations when calling `toString()`.
See the `Ember.Namespace` documentation for more information.
While you can think of your `Ember.Application` as a container that holds the
other classes in your application, there are several other responsibilities
going on under-the-hood that you may want to understand.
### Event Delegation
Ember uses a technique called _event delegation_. This allows the framework
to set up a global, shared event listener instead of requiring each view to
do it manually. For example, instead of each view registering its own
`mousedown` listener on its associated element, Ember sets up a `mousedown`
listener on the `body`.
If a `mousedown` event occurs, Ember will look at the target of the event and
start walking up the DOM node tree, finding corresponding views and invoking
their `mouseDown` method as it goes.
`Ember.Application` has a number of default events that it listens for, as
well as a mapping from lowercase events to camel-cased view method names. For
example, the `keypress` event causes the `keyPress` method on the view to be
called, the `dblclick` event causes `doubleClick` to be called, and so on.
If there is a browser event that Ember does not listen for by default, you
can specify custom events and their corresponding view method names by
setting the application's `customEvents` property:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the loadedmetadata media
// player event
'loadedmetadata': "loadedMetadata"
}
});
```
By default, the application sets up these event listeners on the document
body. However, in cases where you are embedding an Ember application inside
an existing page, you may want it to set up the listeners on an element
inside the body.
For example, if only events inside a DOM element with the ID of `ember-app`
should be delegated, set your application's `rootElement` property:
```javascript
window.App = Ember.Application.create({
rootElement: '#ember-app'
});
```
The `rootElement` can be either a DOM element or a jQuery-compatible selector
string. Note that *views appended to the DOM outside the root element will
not receive events.* If you specify a custom root element, make sure you only
append views inside it!
To learn more about the advantages of event delegation and the Ember view
layer, and a list of the event listeners that are setup by default, visit the
[Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
### Initializers
Libraries on top of Ember can register additional initializers, like so:
```javascript
Ember.Application.initializer({
name: "store",
initialize: function(container, application) {
container.register('store:main', application.Store);
}
});
```
### Routing
In addition to creating your application's router, `Ember.Application` is
also responsible for telling the router when to start routing. Transitions
between routes can be logged with the LOG_TRANSITIONS flag, and more
detailed intra-transition logging can be logged with
the LOG_TRANSITIONS_INTERNAL flag:
```javascript
window.App = Ember.Application.create({
LOG_TRANSITIONS: true, // basic logging of successful transitions
LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
});
```
By default, the router will begin trying to translate the current URL into
application state once the browser emits the `DOMContentReady` event. If you
need to defer routing, you can call the application's `deferReadiness()`
method. Once routing can begin, call the `advanceReadiness()` method.
If there is any setup required before routing begins, you can implement a
`ready()` method on your app that will be invoked immediately before routing
begins.

If you would like additional events to be delegated to your
views, set your `Ember.Application`'s `customEvents` property
to a hash containing the DOM event name as the key and the
corresponding view method name as the value. For example:
```javascript
App = Ember.Application.create({
customEvents: {
// add support for the loadedmetadata media

'loadedmetadata': "loadedMetadata"

/**
StateManager is part of Ember's implementation of a finite state machine. A
StateManager instance manages a number of properties that are instances of
`Ember.State`,
tracks the current active state, and triggers callbacks when states have changed.
## Defining States
The states of StateManager can be declared in one of two ways. First, you can
define a `states` property that contains all the states:
```javascript
managerA = Ember.StateManager.create({
states: {
stateOne: Ember.State.create(),
stateTwo: Ember.State.create()
}
})
managerA.get('states')
// {
// stateOne: Ember.State.create(),
// stateTwo: Ember.State.create()
// }
```
You can also add instances of `Ember.State` (or an `Ember.State` subclass)
directly as properties of a StateManager. These states will be collected into
the `states` property for you.
```javascript
managerA = Ember.StateManager.create({
stateOne: Ember.State.create(),
stateTwo: Ember.State.create()
})
managerA.get('states')
// {
// stateOne: Ember.State.create(),
// stateTwo: Ember.State.create()
// }
```
## The Initial State
When created a StateManager instance will immediately enter into the state
defined as its `start` property or the state referenced by name in its
`initialState` property:
```javascript
managerA = Ember.StateManager.create({
start: Ember.State.create({})
})
managerA.get('currentState.name') // 'start'
managerB = Ember.StateManager.create({
initialState: 'beginHere',
beginHere: Ember.State.create({})
})
managerB.get('currentState.name') // 'beginHere'
```
Because it is a property you may also provide a computed function if you wish
to derive an `initialState` programmatically:
```javascript
managerC = Ember.StateManager.create({
initialState: function(){
if (someLogic) {
return 'active';
} else {
return 'passive';
}
}.property(),
active: Ember.State.create({}),
passive: Ember.State.create({})
})
```
## Moving Between States
A StateManager can have any number of `Ember.State` objects as properties
and can have a single one of these states as its current state.
Calling `transitionTo` transitions between states:
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({}),
poweredUp: Ember.State.create({})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
robotManager.get('currentState.name') // 'poweredUp'
```
Before transitioning into a new state the existing `currentState` will have
its `exit` method called with the StateManager instance as its first argument
and an object representing the transition as its second argument.
After transitioning into a new state the new `currentState` will have its
`enter` method called with the StateManager instance as its first argument
and an object representing the transition as its second argument.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
exit: function(stateManager){
console.log("exiting the poweredDown state")
}
}),
poweredUp: Ember.State.create({
enter: function(stateManager){
console.log("entering the poweredUp state. Destroy all humans.")
}
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
// will log
// 'exiting the poweredDown state'
// 'entering the poweredUp state. Destroy all humans.'
```
Once a StateManager is already in a state, subsequent attempts to enter that
state will not trigger enter or exit method calls. Attempts to transition
into a state that the manager does not have will result in no changes in the
StateManager's current state:
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
exit: function(stateManager){
console.log("exiting the poweredDown state")
}
}),
poweredUp: Ember.State.create({
enter: function(stateManager){
console.log("entering the poweredUp state. Destroy all humans.")
}
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
// will log
// 'exiting the poweredDown state'
// 'entering the poweredUp state. Destroy all humans.'
robotManager.transitionTo('poweredUp') // no logging, no state change
robotManager.transitionTo('someUnknownState') // silently fails
robotManager.get('currentState.name') // 'poweredUp'
```
Each state property may itself contain properties that are instances of
`Ember.State`. The StateManager can transition to specific sub-states in a
series of transitionTo method calls or via a single transitionTo with the
full path to the specific state. The StateManager will also keep track of the
full path to its currentState
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
charging: Ember.State.create(),
charged: Ember.State.create()
}),
poweredUp: Ember.State.create({
mobile: Ember.State.create(),
stationary: Ember.State.create()
})
})
robotManager.get('currentState.name') // 'poweredDown'
robotManager.transitionTo('poweredUp')
robotManager.get('currentState.name') // 'poweredUp'
robotManager.transitionTo('mobile')
robotManager.get('currentState.name') // 'mobile'
// transition via a state path
robotManager.transitionTo('poweredDown.charging')
robotManager.get('currentState.name') // 'charging'
robotManager.get('currentState.path') // 'poweredDown.charging'
```
Enter transition methods will be called for each state and nested child state
in their hierarchical order. Exit methods will be called for each state and
its nested states in reverse hierarchical order.
Exit transitions for a parent state are not called when entering into one of
its child states, only when transitioning to a new section of possible states
in the hierarchy.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown',
poweredDown: Ember.State.create({
enter: function(){},
exit: function(){
console.log("exited poweredDown state")
},
charging: Ember.State.create({
enter: function(){},
exit: function(){}
}),
charged: Ember.State.create({
enter: function(){
console.log("entered charged state")
},
exit: function(){
console.log("exited charged state")
}
})
}),
poweredUp: Ember.State.create({
enter: function(){
console.log("entered poweredUp state")
},
exit: function(){},
mobile: Ember.State.create({
enter: function(){
console.log("entered mobile state")
},
exit: function(){}
}),
stationary: Ember.State.create({
enter: function(){},
exit: function(){}
})
})
})
robotManager.get('currentState.path') // 'poweredDown'
robotManager.transitionTo('charged')
// logs 'entered charged state'
// but does *not* log 'exited poweredDown state'
robotManager.get('currentState.name') // 'charged
robotManager.transitionTo('poweredUp.mobile')
// logs
// 'exited charged state'
// 'exited poweredDown state'
// 'entered poweredUp state'
// 'entered mobile state'
```
During development you can set a StateManager's `enableLogging` property to
`true` to receive console messages of state transitions.
```javascript
robotManager = Ember.StateManager.create({
enableLogging: true
})
```
## Managing currentState with Actions
To control which transitions are possible for a given state, and
appropriately handle external events, the StateManager can receive and
route action messages to its states via the `send` method. Calling to
`send` with an action name will begin searching for a method with the same
name starting at the current state and moving up through the parent states
in a state hierarchy until an appropriate method is found or the StateManager
instance itself is reached.
If an appropriately named method is found it will be called with the state
manager as the first argument and an optional `context` object as the second
argument.
```javascript
managerA = Ember.StateManager.create({
initialState: 'stateOne.substateOne.subsubstateOne',
stateOne: Ember.State.create({
substateOne: Ember.State.create({
anAction: function(manager, context){
console.log("an action was called")
},
subsubstateOne: Ember.State.create({})
})
})
})
managerA.get('currentState.name') // 'subsubstateOne'
managerA.send('anAction')
// 'stateOne.substateOne.subsubstateOne' has no anAction method
// so the 'anAction' method of 'stateOne.substateOne' is called
// and logs "an action was called"
// with managerA as the first argument
// and no second argument
someObject = {}
managerA.send('anAction', someObject)
// the 'anAction' method of 'stateOne.substateOne' is called again
// with managerA as the first argument and
// someObject as the second argument.
```
If the StateManager attempts to send an action but does not find an appropriately named
method in the current state or while moving upwards through the state hierarchy, it will
repeat the process looking for a `unhandledEvent` method. If an `unhandledEvent` method is
found, it will be called with the original event name as the second argument. If an
`unhandledEvent` method is not found, the StateManager will throw a new Ember.Error.
```javascript
managerB = Ember.StateManager.create({

```
Action detection only moves upwards through the state hierarchy from the current state.
It does not search in other portions of the hierarchy.
```javascript
managerC = Ember.StateManager.create({
initialState: 'stateOne.substateOne.subsubstateOne',
stateOne: Ember.State.create({
substateOne: Ember.State.create({
subsubstateOne: Ember.State.create({})
})
}),
stateTwo: Ember.State.create({
anAction: function(manager, context){
// will not be called below because it is
// not a parent of the current state
}
})
})
managerC.get('currentState.name') // 'subsubstateOne'
managerC.send('anAction')
// Error: <Ember.StateManager:ember132> could not
// respond to event anAction in state stateOne.substateOne.subsubstateOne.
```
Inside of an action method the given state should delegate `transitionTo` calls on its
StateManager.
```javascript
robotManager = Ember.StateManager.create({
initialState: 'poweredDown.charging',
poweredDown: Ember.State.create({
charging: Ember.State.create({
chargeComplete: function(manager, context){
manager.transitionTo('charged')
}
}),
charged: Ember.State.create({
boot: function(manager, context){
manager.transitionTo('poweredUp')
}
})
}),
poweredUp: Ember.State.create({
beginExtermination: function(manager, context){
manager.transitionTo('rampaging')
},
rampaging: Ember.State.create()
})
})
robotManager.get('currentState.name') // 'charging'
robotManager.send('boot') // throws error, no boot action
// in current hierarchy
robotManager.get('currentState.name') // remains 'charging'
robotManager.send('beginExtermination') // throws error, no beginExtermination
// action in current hierarchy
robotManager.get('currentState.name') // remains 'charging'
robotManager.send('chargeComplete')
robotManager.get('currentState.name') // 'charged'
robotManager.send('boot')
robotManager.get('currentState.name') // 'poweredUp'
robotManager.send('beginExtermination', allHumans)
robotManager.get('currentState.name') // 'rampaging'
```
Transition actions can also be created using the `transitionTo` method of the `Ember.State` class. The
following example StateManagers are equivalent:
```javascript
aManager = Ember.StateManager.create({
stateOne: Ember.State.create({
changeToStateTwo: Ember.State.transitionTo('stateTwo')
}),
stateTwo: Ember.State.create({})
})
bManager = Ember.StateManager.create({
stateOne: Ember.State.create({
changeToStateTwo: function(manager, context){
manager.transitionTo('stateTwo', context)
}
}),
stateTwo: Ember.State.create({})
})
```

/*
* Internal implementation notes.
*
* The exchange manager is one by default in libfc but LLD may choose
* to have one per CPU. The sequence manager is one per exchange manager
* and currently never separated.
*
* Section 9.8 in FC-FS-2 specifies: "The SEQ_ID is a one-byte field
* assigned by the Sequence Initiator that shall be unique for a specific
* D_ID and S_ID pair while the Sequence is open." Note that it isn't
* qualified by exchange ID, which one might think it would be.
* In practice this limits the number of open sequences and exchanges to 256
* per session. For most targets we could treat this limit as per exchange.
*
* The exchange and its sequence are freed when the last sequence is received.
* It's possible for the remote port to leave an exchange open without
* sending any sequences.
*
* Notes on reference counts:
*
* Exchanges are reference counted and exchange gets freed when the reference
* count becomes zero.
*
* Timeouts:
* Sequences are timed out for E_D_TOV and R_A_TOV.
*
* Sequence event handling:
*
* The following events may occur on initiator sequences:
*
* Send.
* For now, the whole thing is sent.
* Receive ACK
* This applies only to class F.
* The sequence is marked complete.
* ULP completion.
* The upper layer calls fc_exch_done() when done
* with exchange and sequence tuple.
* RX-inferred completion.
* When we receive the next sequence on the same exchange, we can
* retire the previous sequence ID. (XXX not implemented).
* Timeout.
* R_A_TOV frees the sequence ID. If we're waiting for ACK,
* E_D_TOV causes abort and calls upper layer response handler
* with FC_EX_TIMEOUT error.
* Receive RJT
* XXX defer.
* Send ABTS
* On timeout.
*
* The following events may occur on recipient sequences:
*
* Receive
* Allocate sequence for first frame received.
* Hold during receive handler.
* Release when final frame received.
* Keep status of last N of these for the ELS RES command. XXX TBD.
* Receive ABTS
* Deallocate sequence
* Send RJT
* Deallocate
*
* For now, we neglect conditions where only part of a sequence was
* received or transmitted, or where out-of-order receipt is detected.
*/
/*
* Locking notes:
*
* The EM code run in a per-CPU worker thread.
*
* To protect against concurrency between a worker thread code and timers,
* sequence allocation and deallocation must be locked.
* - exchange refcnt can be done atomicly without locks.
* - sequence allocation must be locked by exch lock.
* - If the EM pool lock and ex_lock must be taken at the same time, then the

<br>
<br><b>Errors</b>
<p>The DBcursor->count method
may fail and return one of the following non-zero errors:</p>
<br>
<b>DB_REP_HANDLE_DEAD</b><ul compact><li>The database handle has been invalidated because a replication election
unrolled a committed transaction.</ul>
<br>
<br>
<b>DB_REP_LOCKOUT</b><ul compact><li>The operation was blocked by client/master synchronization.</ul>
<br>
<br>
<b>EINVAL</b><ul compact><li>If the cursor has not been initialized; or if an

このセクションではルータの高度なフィーチャーとどのようにしてアプリケーション内の複雑な非同期のロジックを扱えるようにしているかを紹介します。
### プロミスについて...
Emberは、ルーターの非同期のロジックを扱うのにプロミスの概念を多用しています。 一言で言えば、プロミスはのちに起こる値を表すオブジェクトです。 プロミスは*成功*(値の解決に成功) または *リジェクト* (値の解決に失敗) のいずれかとなります。 最終の値を取得する、またはプロミスがリジェクトされた場合のハンドリングは成功、リジェクトの二つのコールバックを受け取ることのできる、プロミスの[`then()`](http://emberjs.com/api/classes/RSVP.Promise.html#method_then)メソッドで処理します。 もし、プロミスが成功すれば、成功の値とともに、成功時のハンドロラーが呼び出されます、また、プロミスがリジェクトされた場合はリジェクトされた理由とともに、リジェクトハンドラーが呼び出されます。 例えば
```js
var promise = fetchTheAnswer();
promise.then(fulfill, reject);
function fulfill(answer) {
console.log(`The answer is ${answer}`);
}
function reject(reason) {
console.log(`Couldn't get the answer! Reason: ${reason}`);
}
```
プロミスの力点は、非同期のオペレーションを次々と処理される、列として処理できることです。
```js
// Note: jQuery AJAX メソッドはプロミスを返します。
var usernamesPromise = Ember.$.getJSON('/usernames.json');
usernamesPromise.then(fetchPhotosOfUsers)
.then(applyInstagramFilters)
.then(uploadTrendyPhotoAlbum)
.then(displaySuccessMessage, handleErrors);
```
上記の例では、もし`fetchPhotosOfUsers` `applyInstagramFilters` `uploadTrendyPhotoAlbum`のいずれかのメソッドがプロミスのリジェクトを返したら、`handleErrors`が失敗の理由とともに呼び出されます。 このようにして、プロミスはコールバックが右に深くなっていくのを回避して、アプリケーションの非同期のロジックへのアプローチを容易にするtry-catchステートメントが行う非同期の方法に似ています。
このガイドはプロミスを利用できる様々な方法を全て深堀することはしません、しかし[RSVP](https://github.com/tildeio/rsvp.js)のreadmeを見れば、より深くプロミスを紹介しています。
### プロミスのためのルーターの停止
Ember router (Ember ルーター)は route (ルート)間の transitio (遷移)では、transitio (遷移)の完了時にroute (ルート)の controller (コントラーラ)に渡される、models (モデル) (`model` hook (モデルフック)経由で)を回収します。 もし`model` hook (または、関連する `beforeModel` あるいは`afterModel` hooks) が通常のオブジェクト(プロミスではない) を返した場合は、transition (遷移) は即座に完了します。 しかし、もし`model` hook (`モデル` フック) (あるいは、関係のある `beforeModel` hook (`ビフォーモデル` フック) または、<0>afterModel</0> hook (<0>アフターモデル</0> フック) ) がプロミス (あるいは、<0>transitionTo</0>の要素として、プロミスが提供された場合) を返した場合、 transition (遷移) はプロミスが、成功またはリジェクトされるまで一時停止します。
router (ルーター) は`then()`メソッドで定義されているものを、 promise (プロミス) であると判断します。
promise (プロミス) が成功した場合、 transition (遷移) が中断していたところから再開し、次の (子) route (ルート) の model (モデル) を解決します、次が promise (プロミス) の場合は一旦中断をする、この一連の動きを繰り返し全ての route model(ルート モデル) が解決されるまで繰り返します。 各 route (ルート) に渡される[`setupController()`](http://emberjs.com/api/classes/Ember.Route.html#method_setupController) hook <0>setupController()</0> hook (<0>セットアップコントローラー</0> フック) の値は、成功した promise (プロミス) の値になります。
簡単な例:
```app/routes/tardy.js export default Ember.Route.extend({ model() { return new Ember.RSVP.Promise(function(resolve) { Ember.run.later(function() { resolve({ msg: 'Hold Your Horses' }); }, 3000); }); },
setupController(controller, model) { console.log(model.msg); // "Hold Your Horses" } });
<br />`route:tardy`に transition (遷移) するとき、3秒経つまで満たされることのない、promise (プロミス) として`model()` hook (`モデル()` フック) が呼ばれ、 その間、 router (ルーター) は mid-transition (遷移中) として一時中断されます。 最終的に、 promise (プロミス) が満たされると、 router (ルーター) は transition (遷移) を継続して、最終的に`route:tardy`の `setupController()` hook (`setupController()`フック)を呼び出し、オブジェクトを解決します。
pause-on-promise (プロミスを中断) の動作は、 route (ルート) の新しいデータが、新しい template (テンプレート) を確実に表示するようにしたいときなどに有効です。
### Promises (プロミス)がリジェクトされたとき...
すでに、promise (プロミス)が成功したときについては紹介しましたが、リジェクトされた場合はどうでしょうか？
デフォルトで、transition (遷移)中に、model promise (モデル プロミス)がリジェクトされると、transition (遷移)は中止されます、新しく対象のroute templates (ルート テンプレート)が描画されることはありません、そしてコンソールにエラーが出力されます。
この、エラーハンドリングのロジックは、route (ルート)の`actions` hash (アクションハッシュ)の`error` handler (エラーハンドラー)経由で設定できます。 プロミスが拒否すると、ルートで`error` イベントが発生しカスタムエラーハンドラーで処理しないがぎり、`route:application`'のデフォルトのエラーハンドラーまで遡ります、例:
```app/routes/good-for-nothing.js
export default Ember.Route.extend({
model() {
return Ember.RSVP.reject("FAIL");
},
actions: {
error(reason) {
alert(reason); // "FAIL"
// Can transition to another route here, e.g.
// this.transitionTo('index');
// Uncomment the line below to bubble this error event:
// return true;
}
}
});
上記の例では、error event (エラーイベント)は`route:good-for-nothing`の error handler (エラーハンドラー)で止まり、上昇していくのは止まります。 `route:application`まで、イベントの上昇を続けるにはerror handler (エラーハンドラー)からtrueを返すことで可能になります。
### リジェクトからの回復
モデルのプロミスがリジェクトされた場合遷移は中断されますが、プロミスは連結することができため、プロミスのリジェクトを`モデル`フック自身で受け取り、遷移を中断しない成功として遷移の中断が発生しないように成功に変換することができます。
app/routes/funky.js
export default Ember.Route.extend({
model() {
return iHopeThisWorks().catch(function() {
// Promise rejected, fulfill with some default value to
// use as the route's model and continue on with the transition
return { msg: 'Recovered from rejected promise' };
});
}
});

title: Toetav Mõte
date: 17/01/2020

On õpetlik märkida, et Tn 2. ptk kuju on tehtud kullast ja hõbedast, majanduslikku võimsust näitavatest metallidest. Samuti on see tehtud vasest ja rauast, mida kasutatakse tööriistade ja relvade valmistamisel, ning savist, mida kasutati muistsel ajal kirjanduse vallas ja kodumajapidamises. Nii annab kuju ereda pildi inimlikkusest ja selle saavutustest. Kuju erinevad kehaosad näitavad väga otstarbekalt maailmariikide järgnevust ja viimaks lõhenemist, mis valitseb maailmaajaloo lõpupäevil. Kivi kujutatakse aga selgelt millenagi, mis on ilma „[inimese] käte abita“ (Tn 2:45); see tuletab meile jõuliselt meelde üleloomulikku lõppu, mis sellele lühiaegsele maailmale ja kõigile inimeste saavutustele saabub.
„Kuigi puht inimliku silmaga vaadates võib inimsoo ajalugu näida kaootilise jõudude koosmõju ja vastasmõjuna…, kinnitab Taanieli raamat meile, et kõige taga seisab Jumal, kes hoiab kõigel pilku peal ja liigub toimuva keskel, et viia edukalt lõpule see, mida Tema näeb parima olevat.“ – William H. Shea, „Daniel: A Reader’s Guide“ (Nampa, ID: Pacific Press, 2005), lk 98.
Üks Nigeeria üliõpilane kaotas kogu omandi tulekahjus, mis sulatas üles isegi raudtorud tema korteris, kuid ta oli rabatud, kui leidis, et tulest puutumata oli jäänud üks Ellen G. White’i raamat – „Suur lootus“.
Üliõpilane, Olajide Oluwatobi Igbinyemi, luges raamatu hoobilt läbi ja tõttas kohalikku seitsmenda päeva adventistide kogudusse, kelle liikmed olid talle kirjandusevangelismi hingamispäeval raamatu andnud.
„See raamat on imeline, suurepärane,“ rääkis Igbinyemi üllatunud koguduseliikmetele, hoides samal ajal käes puutumata jäänud „Suurt lootust“,
11 peatükile lühendatud varianti „Suurest võitlusest“.
„Ma ei ole varem sedasorti raamatut näinud!“ ütles ta. „See ime pani mind raamatut kaanest kaaneni läbi lugema.“
Koguduseliikmed kinkisid raamatu 30aastasele Igbinyemile Edes, linnas, mis asub Nigeeria pealinnast Lagosest umbes 220 km põhja pool. Koguduseliikmed, kes võtsid osa ülemaailmsest koguduse projektist „Misjon linnadele“, levitasid linnades üle kogu maailma miljard väljaannet. Nad jagasid tuhandeid „Suure lootuse“ eksemplare kord veerandaastas „suure lootuse päeval“, erilisel raamatute jagamiseks mõeldud hingamispäeval Nigeeria osariigis Osunis, ütles Joseph Adebomi, adventkoguduste Osuni Liidu esimees,
Kuid seejärel läks Igbinyemi, kes oli Edes asuva Nigeeria kõrgkooli, Föderaalse Polütehnikumi üliõpilane 2018. aastal reisile ja jättis raamatu üürile võetud ühetoalisse korterisse. Kui ta tagasi tuli, leidis ta, et tuli oli majas möllanud. Tema kooliraamatud, mööbel ja madrats olid hävinud.
„Isegi raud sulas,“ ütles Adebomi.
Tulekahju põhjus ei olnudki päris selge.
Kuid kui Igbinyemi tuhas sobras, leidis ta „Suure lootuse“.
Sellel päeval luges ta õhinal lõpuni raamatu, kus räägitakse ajaloost ja prohvetikuulutusest, mis seletab lahti tänapäeva maailma kaose mõtte. Siis jooksis ta adventkogudusse, et oma lugu rääkida.
„Te ei teagi, mis raamatut te jagate,“ oli ta Adebomi sõnade kohaselt öelnud. „Selles on Jumala vägi.“
Igbinyemi põlvitas koguduse ees ja ülistas Jumalat.
See lugu puudutab südant ja kasvatab inimeste usku Nigeeria osariigis Osunis.
„Olen kuulnud Piiblitest, mis on jäänud tules põlemata, aga eales varem pole ma kuulnud ühestki teisest põlemata jäänud raamatust,“ ütles Onaolapo Ajibade, emeriitpastor ning kunagine Lääne- ja Kesk-Aafrika Divisjoni täitevsekretär, kelle territooriumile Nigeeria jääb. Ta elab Osuni osariigis Inisas. „See ime on suurendanud minu armastust prohvetikuulutamise vaimu raamatute vastu.“
## Küsimused aruteluks:
`1. Kui hea on teada, et kogu selle maailma kaose ja kannatuste keskel on Jumala käes lõplik kontroll ja ta viib kõik aulise lõpuni. Milline osa on meil sinnamaani kogu selle hea poole püüdlemises ja kuidas saame aidata pattulangenud maailmas olevate kannatuste leevendamisel?`
`2. Kuidas selgitad seda, et Taaniel ja teised vangid tegid tihedat ning ilmselt ustavat koostööd paganliku juhiga, kes oli Taanieli rahvale nii suure hävingu toonud?`
`3. Nagu nägime, on osa inimesi väitnud, et käte abita lahti murdunud kivi osutab evangeeliumi levitamisele maailmas. See ei saa olla tõene mitmel põhjusel, kaasa arvatud Tn 2:35 öeldu, kus on kirjas, et kivi purustas eelnevad riigid ja need „said aganate sarnaseks suviselt rehealuselt: tuul viis need ära ja neist ei leidunud jälgegi“. Pärast risti ei toimunud nii. Lisaks luhtuvad püüded samastada kivi-riiki kogudusega, sest kivi-riik tuleb kõikide teiste inimlike valitsusvormide asemele. Tegemist on riigiga, mis haarab kogu maailma. Seega saab ainult Jeesuse taastulek käivitada protsessi, millega see prohvetlik unenägu tipneb. Miks on Jeesuse teine tulemine ainus mõistlik tõlgendus selle kohta, mida kivi lõpuajal teeb?`

# Getting Started with Angular: Your First App
Welcome to Angular!
This tutorial introduces you to the essentials of Angular by walking you through a simple e-commerce site with a catalog, shopping cart, and check-out form.
To help you get started right away, this guide uses a simple ready-made application that you can examine and play with interactively.
<div class="callout is-helpful">
<header>New to web development?</header>
There are many resources to complement the Angular docs. Mozilla's MDN docs include both [HTML](https://developer.mozilla.org/en-US/docs/Learn/HTML "Learning HTML: Guides and tutorials") and [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript "JavaScript") introductions. [TypeScript's docs](https://www.typescriptlang.org/docs/home.html "TypeScript documentation") include a 5-minute tutorial. Various online course platforms, such as [Udemy](http://www.udemy.com "Udemy online courses") and [Codecademy](https://www.codecademy.com/ "Codecademy online courses"), also cover web development basics.
</div>
{@a new-project}
## Create a new project
<h4>
<live-example name="getting-started-v0" noDownload>Click here to create the ready-made sample project in StackBlitz.</live-example>
</h4>
<div class="lightbox">
<img src="generated/images/guide/start/new-app-all.gif" alt="Starter online store app">
</div>
* The preview pane on the right shows the starting state of the sample Angular app.
It defines a frame with a top bar (containing the store name and checkout icon) and the title for a product list (which will be populated and dynamically updated with data from the application).
* The project pane on the left shows the source files that make up the application, including all of the infrastructure and configuration files. The currently selected file shows up in the editor pane in the middle.
Before going into the source structure, the next section shows how to fill out the HTML *template* for the product list, using the provided sample data.
This should give you an idea how easy it is to modify and update the page dynamically.
<div class="callout is-helpful">
<header>StackBlitz tips</header>
* Log into StackBlitz so you can save and resume your work.
If you have a GitHub account, you can log into StackBlitz
with that account. In order to save your progress, first
fork the project using the Fork button at the top left,
then you'll be able to save your work to your own StackBlitz
account by clicking the Save button.
* To copy a code example from this tutorial, click the icon
at the top right of the code example box, and then paste the
code snippet from the clipboard into StackBlitz.
* If the StackBlitz preview pane isn't showing what you
expect, save and then click the refresh button.
* StackBlitz is continually improving, so there may be
slight differences in generated code, but the app's
behavior will be the same.
* When you generate the StackBlitz example apps that
accompany the tutorials, StackBlitz creates the starter
files and mock data for you. The files you'll use throughout
the tutorials are in the `src` folder of the StackBlitz
example apps.
</div>
<div class="alert is-helpful">
If you go directly to the [StackBlitz online development environment](https://stackblitz.com/) and choose to [start a new Angular workspace](https://stackblitz.com/fork/angular), you get a generic stub application, rather than this [illustrative sample](#new-project). Once you have been introduced to the basic concepts here, this can be helpful for working interactively while you are learning Angular.
In actual development you will typically use the [Angular CLI](guide/glossary#command-line-interface-cli), a powerful command-line tool that lets you generate and modify applications. For more information, see the [CLI Overview](cli).
</div>
{@a template-syntax}
## Template syntax
Angular's template syntax extends HTML and JavaScript.
This section introduces template syntax by enhancing the "Products" area.
<div class="alert is-helpful">
To help you get going, the following steps use predefined product data from the `products.ts` file (already created in StackBlitz example) and methods from the `product-list.component.ts` file.
</div>
1. In the `product-list` folder, open the template file `product-list.component.html`.
1. Modify the product list template to display a list of product names.
1. Each product in the list displays the same way, one after another on the page. To iterate over the predefined list of products, put the `*ngFor` directive on a `<div>`, as follows:
<code-example header="src/app/product-list/product-list.component.html" path="getting-started/src/app/product-list/product-list.component.2.html" region="ngfor">
</code-example>
With `*ngFor`, the `<div>` repeats for each product in the list.
<div class="alert is-helpful">
`*ngFor` is a "structural directive". Structural directives shape or reshape the DOM's structure, typically by adding, removing, and manipulating the elements to which they are attached. Directives with an asterisk, `*`, are structural directives.
</div>
1. To display the names of the products, use the interpolation syntax `{{ }}`. Interpolation renders a property's value as text. Inside the `<div>`, add an `<h3>` to display the interpolation of the product's name property:
<code-example path="getting-started/src/app/product-list/product-list.component.2.html" header="src/app/product-list/product-list.component.html" region="interpolation">
</code-example>
The preview pane immediately updates to display the name of each product in the list.
<div class="lightbox">
<img src="generated/images/guide/start/template-syntax-product-names.png" alt="Product names added to list">
</div>
1. To make each product name a link to product details, add the `<a>` element and set its title to be the product's name by using the property binding `[ ]` syntax, as follows:
<code-example path="getting-started/src/app/product-list/product-list.component.2.html" header="src/app/product-list/product-list.component.html">
</code-example>
In the preview pane, hold the pointer over a product
name to see the bound name property value, which is
the product name plus the word "details".
Interpolation `{{ }}` lets you render the
property value as text; property binding `[ ]` lets you
use the property value in a template expression.
<div class="lightbox">
<img src="generated/images/guide/start/template-syntax-product-anchor.png" alt="Product name anchor text is product name property">
</div>
4. Add the product descriptions. On the `<p>` element, use an `*ngIf` directive so that Angular only creates the `<p>` element if the current product has a description.
<code-example path="getting-started/src/app/product-list/product-list.component.3.html" header="src/app/product-list/product-list.component.html">
</code-example>
The app now displays the name and description of each product in the list. Notice that the final product does not have a description paragraph. Because the product's description property is empty, Angular doesn't create the `<p>` element—including the word "Description".
<div class="lightbox">
<img src="generated/images/guide/start/template-syntax-product-description.png" alt="Product descriptions added to list">
</div>
5. Add a button so users can share a product with friends. Bind the button's `click` event to the `share()` method (in `product-list.component.ts`). Event binding uses a set of parentheses, `( )`, around the event, as in the following `<button>` element:
<code-example path="getting-started/src/app/product-list/product-list.component.4.html" header="src/app/product-list/product-list.component.html">
</code-example>
Each product now has a "Share" button:
<div class="lightbox">
<img src="generated/images/guide/start/template-syntax-product-share-button.png" alt="Share button added for each product">
</div>
Test the "Share" button:
<div class="lightbox">
<img src="generated/images/guide/start/template-syntax-product-share-alert.png" alt="Alert box indicating product has been shared">
</div>
The app now has a product list and sharing feature.
In the process, you've learned to use five common features of Angular's template syntax:
* `*ngFor`
* `*ngIf`
* Interpolation `{{ }}`
* Property binding `[ ]`
* Event binding `( )`
<div class="alert is-helpful">
For more information about the full capabilities of Angular's
template syntax, see [Template Syntax](guide/template-syntax "Template Syntax").
</div>
{@a components}
## Components
*Components* define areas of responsibility in the user interface, or UI,
that let you reuse sets of UI functionality.
You've already built one with the product list component.
A component consists of three things:
* **A component class** that handles data and functionality. In the previous section, the product data and the `share()` method in the component class handle data and functionality, respectively.
* **An HTML template** that determines the UI. In the previous section, the product list's HTML template displays the name, description, and a "Share" button for each product.
* **Component-specific styles** that define the look and feel.
Though product list does not define any styles, this is where component CSS
resides.
<!--
### Class definition
Let's take a quick look a the product list component's class definition:
1. In the `product-list` directory, open `product-list.component.ts`.
1. Notice the `@Component` decorator. This provides metadata about the component, including its templates, styles, and a selector.
* The `selector` is used to identify the component. The selector is the name you give the Angular component when it is rendered as an HTML element on the page. By convention, Angular component selectors begin with the prefix such as `app-`, followed by the component name.
* The template and style filename also are provided here. By convention each of the component's parts is in a separate file, all in the same directory and with the same prefix.
1. The component definition also includes an exported class, which handles functionality for the component. This is where the product list data and `Share()` method are defined.
### Composition
-->
An Angular application comprises a tree of components, in which each Angular component has a specific purpose and responsibility.
Currently, the example app has three components:
<div class="lightbox">
<img src="generated/images/guide/start/app-components.png" alt="Online store with three components">
</div>
* `app-root` (orange box) is the application shell. This is the first component to load and the parent of all other components. You can think of it as the base page.
* `app-top-bar` (blue background) is the store name and checkout button.
* `app-product-list` (purple box) is the product list that you modified in the previous section.
The next section expands the app's capabilities by adding a new component—a product alert—as a child of the product list component.
<div class="alert is-helpful">
For more information about components and how they interact with templates, see [Introduction to Components](guide/architecture-components "Architecture > Introduction to Components").
</div>
{@a input}
## Input
Currently, the product list displays the name and description of each product.
The product list component also defines a `products` property that contains imported data for each product from the `products` array in `products.ts`.
The next step is to create a new alert feature that takes a product as an input. The alert checks the product's price, and, if the price is greater than $700, displays a "Notify Me" button that lets users sign up for notifications when the product goes on sale.
1. Create a new product alerts component.
1. Right click on the `app` folder and use the `Angular Generator` to generate a new component named `product-alerts`.
<div class="lightbox">
<img src="generated/images/guide/start/generate-component.png" alt="StackBlitz command to generate component">
</div>
The generator creates starter files for all three parts of the component:
* `product-alerts.component.ts`
* `product-alerts.component.html`
* `product-alerts.component.css`
1. Open `product-alerts.component.ts`.
<code-example header="src/app/product-alerts/product-alerts.component.ts" path="getting-started/src/app/product-alerts/product-alerts.component.1.ts" region="as-generated"></code-example>
1. Notice the `@Component()` decorator. This indicates that the following class is a component. It provides metadata about the component, including its selector, templates, and styles.
* The `selector` identifies the component. The selector is the name you give the Angular component when it is rendered as an HTML element on the page. By convention, Angular component selectors begin with the prefix `app-`, followed by the component name.
* The template and style filenames reference the HTML and CSS files that StackBlitz generates.
1. The component definition also exports the class, `ProductAlertsComponent`, which handles functionality for the component.
1. Set up the new product alerts component to receive a product as input:
1. Import `Input` from `@angular/core`.
<code-example path="getting-started/src/app/product-alerts/product-alerts.component.1.ts" region="imports" header="src/app/product-alerts/product-alerts.component.ts"></code-example>
1. In the `ProductAlertsComponent` class definition, define a property named `product` with an `@Input()` decorator. The `@Input()` decorator indicates that the property value passes in from the component's parent, the product list component.
<code-example path="getting-started/src/app/product-alerts/product-alerts.component.1.ts" region="input-decorator" header="src/app/product-alerts/product-alerts.component.ts"></code-example>
1. Define the view for the new product alert component.
1. Open the `product-alerts.component.html` template and replace the placeholder paragraph with a "Notify Me" button that appears if the product price is over $700.
<code-example header="src/app/product-alerts/product-alerts.component.html" path="getting-started/src/app/product-alerts/product-alerts.component.1.html"></code-example>
1. Display the new product alert component as a child of the product list.
1. Open `product-list.component.html`.
1. To include the new component, use its selector, `app-product-alerts`, as you would an HTML element.
1. Pass the current product as input to the component using property binding.
<code-example header="src/app/product-list/product-list.component.html" path="getting-started/src/app/product-list/product-list.component.5.html" region="app-product-alerts"></code-example>
The new product alert component takes a product as input from the product list. With that input, it shows or hides the "Notify Me" button, based on the price of the product. The Phone XL price is over $700, so the "Notify Me" button appears on that product.
<div class="lightbox">
<img src="generated/images/guide/start/product-alert-button.png" alt="Product alert button added to products over $700">
</div>
<div class="alert is-helpful">
See [Component Interaction](guide/component-interaction "Components & Templates > Component Interaction") for more information about passing data from a parent to child component, intercepting and acting upon a value from the parent, and detecting and acting on changes to input property values.
</div>
{@a output}
## Output
To make the "Notify Me" button work, you need to configure two things:
- the product alert component to emit an event when the user clicks "Notify Me"
- the product list component to act on that event
1. Open `product-alerts.component.ts`.
1. Import `Output` and `EventEmitter` from `@angular/core`:
<code-example header="src/app/product-alerts/product-alerts.component.ts" path="getting-started/src/app/product-alerts/product-alerts.component.ts" region="imports"></code-example>
1. In the component class, define a property named `notify` with an `@Output()` decorator and an instance of `EventEmitter()`. This allows the product alert component to emit an event when the value of the notify property changes.
<div class="alert is-helpful">
When the Angular CLI generates a new component, it includes an empty constructor, the `OnInit` interface, and the `ngOnInit()` method.
Since the following example isn't using them, they are omitted here for brevity.
</div>
<code-example path="getting-started/src/app/product-alerts/product-alerts.component.ts" header="src/app/product-alerts/product-alerts.component.ts" region="input-output"></code-example>
1. In the product alert template, `product-alerts.component.html`, update the "Notify Me" button with an event binding to call the `notify.emit()` method.
<code-example header="src/app/product-alerts/product-alerts.component.html" path="getting-started/src/app/product-alerts/product-alerts.component.html"></code-example>
1. Next, define the behavior that should happen when the user clicks the button. Recall that it's the parent, product list component—not the product alerts component—that acts when the child raises the event. In `product-list.component.ts`, define an `onNotify()` method, similar to the `share()` method:
<code-example header="src/app/product-list/product-list.component.ts" path="getting-started/src/app/product-list/product-list.component.ts" region="on-notify"></code-example>
1. Finally, update the product list component to receive output from the product alerts component.
In `product-list.component.html`, bind the `app-product-alerts` component (which is what displays the "Notify Me" button) to the `onNotify()` method of the product list component.
<code-example header="src/app/product-list/product-list.component.html" path="getting-started/src/app/product-list/product-list.component.6.html" region="on-notify"></code-example>
1. Try the "Notify Me" button:
<div class="lightbox">
<img src="generated/images/guide/start/product-alert-notification.png" alt="Product alert notification confirmation dialog">
</div>
<div class="alert is-helpful">
See [Component Interaction](guide/component-interaction "Components & Templates > Component Interaction") for more information about listening for events from child components, reading child properties or invoking child methods, and using a service for bi-directional communication between components.
</div>
{@a next-steps}
## Next steps
Congratulations! You've completed your first Angular app!
You have a basic online store catalog with a product list, "Share" button, and "Notify Me" button.
You've learned about the foundation of Angular: components and template syntax.
You've also learned how the component class and template interact, and how components communicate with each other.
To continue exploring Angular, choose either of the following options:
* [Continue to the "Routing" section](start/start-routing "Getting Started: Routing") to create a product details page that can be accessed by clicking a product name and that has its own URL pattern.
* [Skip ahead to the "Deployment" section](start/start-deployment "Getting Started: Deployment") to move to local development, or deploy your app to Firebase or your own server.

<div class="refsect1">
<a name="idp7808080"></a><h2>Description</h2>
<p>trait = the name of the metafunction. ... = variadic parameters.</p>
<p>The first variadic parameter is the inner class template name.</p>
<p>Following variadic parameters are optional.</p>
<p>If no following variadic parameters exist, then the inner class template being introspected must be all template type parameters ( template parameters starting with `class` or `typename` ) and any number of template type parameters can occur.</p>
<p>If the second variadic parameter is BOOST_PP_NIL and no other variadic parameter is given, then just as in the previous case the inner class template being introspected must be all template type parameters ( template parameters starting with `class` or `typename` ) and any number of template type parameters can occur. This form is allowed in order to be consistent with using the non-variadic form of this macro.</p>
<p>If the second variadic parameter is a Boost preprocessor library array and no other variadic parameter is given, then the inner class template must have its template parameters matching the sequence in the tuple portion of the Boost PP array. This form is allowed in order to be consistent with using the non-variadic form of this macro.</p>
<p>Otherwise the inner class template must have its template parameters matching the sequence of the optional variadic parameters.</p>
<p>generates a metafunction called "trait" where 'trait' is the first macro parameter.</p>
<p>template<class BOOST_TTI_TP_T> struct trait { static const value = unspecified; typedef mpl::bool_<true-or-false> type; };</p>
<p>The metafunction types and return:</p>
<p>BOOST_TTI_TP_T = the enclosing type in which to look for our 'name'.</p>
<p>returns = 'value' is true if the 'name' template exists within the enclosing type, otherwise 'value' is false.</p>
<p>Examples:</p>
<p>1) Search for an inner class template called 'MyTemplate', with all template type parameters, nested within the class 'MyClass' using a metafunction name of 'MyMeta'.</p>
<p>BOOST_TTI_TRAIT_HAS_TEMPLATE(MyMeta,MyTemplate)</p>
<p>or</p>
<p>BOOST_TTI_TRAIT_HAS_TEMPLATE(MyMeta,MyTemplate,BOOST_PP_NIL) // Non-variadic macro form</p>
<p>MyMeta<MyClass>::value</p>
<p>is a compile time boolean constant which is either 'true' or 'false' if the nested template exists.</p>
<p>2) Search for an inner class template called 'MyTemplate', with template parameters of 'class T,int x,template<class> class U', nested within the class 'MyClass' using a metafunction name of 'MyMeta'.</p>
<p>BOOST_TTI_TRAIT_HAS_TEMPLATE(MyMeta,MyTemplate,class,int,template<class> class)</p>
<p>or</p>
<p>BOOST_TTI_TRAIT_HAS_TEMPLATE(MyMeta,MyTemplate,(3,(class,int,template<class> class))) // Non-variadic macro form</p>

<h2 id="synopsis">SYNOPSIS</h2>
<pre><code>npm.commands.bugs(package, callback)
</code></pre><h2 id="description">DESCRIPTION</h2>
<p>This command tries to guess at the likely location of a package's
bug tracker URL, and then tries to open it using the <code>--browser</code>
config param.</p>
<p>Like other commands, the first parameter is an array. This command only
uses the first element, which is expected to be a package name with an
optional version number.</p>
<p>This command will launch a browser, so this command may not be the most
friendly for programmatic use.</p>

/***************************************************/
/*! \class FileWvIn
\brief STK audio file input class.
This class inherits from WvIn. It provides a "tick-level"
interface to the FileRead class. It also provides variable-rate
playback functionality. Audio file support is provided by the
FileRead class. Linear interpolation is used for fractional read
rates.
FileWvIn supports multi-channel data. It is important to
distinguish the tick() method that computes a single frame (and
returns only the specified sample of a multi-channel frame) from
the overloaded one that takes an StkFrames object for
multi-channel and/or multi-frame data.
FileWvIn will either load the entire content of an audio file into
local memory or incrementally read file data from disk in chunks.
This behavior is controlled by the optional constructor arguments
\e chunkThreshold and \e chunkSize. File sizes greater than \e
chunkThreshold (in sample frames) will be read incrementally in
chunks of \e chunkSize each (also in sample frames).
When the file end is reached, subsequent calls to the tick()
functions return zeros and isFinished() returns \e true.
See the FileRead class for a description of the supported audio
file formats.

<h4 align=center>OS/161 Reference Manual</h4>
<h3>Name</h3>
cp - copy files
<h3>Synopsis</h3>
/bin/cp <em>oldfile</em> <em>newfile</em>
<h3>Description</h3>
cp copies the file <em>oldfile</em> to the file <em>newfile</em>,
overwriting <em>newfile</em> if it already exists.
<p>
cp supports no options.
<p>
<h3>Requirements</h3>
cp uses the following syscalls:
<ul>
<li><A HREF=../syscall/open.html>open</A>
<li><A HREF=../syscall/read.html>read</A>
<li><A HREF=../syscall/write.html>write</A>
<li><A HREF=../syscall/close.html>close</A>
<li><A HREF=../syscall/_exit.html>_exit</A>
</ul>
cp should function properly once the basic system calls assignment is
completed.

# Code Generation
## Swagger to SDK
This section describes what SDK should be generated by the automatic system.
This is not used by Autorest itself.
``` yaml $(swagger-to-sdk)
swagger-to-sdk:
- repo: azure-sdk-for-go
- repo: azure-sdk-for-python
- repo: azure-sdk-for-node
- repo: azure-sdk-for-ruby
after_scripts:
- bundle install && rake arm:regen_all_profiles['azure_cognitiveservices_websearch']
```
## CSharp Settings
These settings apply only when `--csharp` is specified on the command line.
``` yaml $(csharp)
csharp:
namespace: Microsoft.Azure.CognitiveServices.Search.WebSearch
output-folder: $(csharp-sdks-folder)/CognitiveServices/dataPlane/Search/BingWebSearch/BingWebSearch/Generated/WebSearch
sync-methods: none
```
## Python
These settings apply only when `--python` is specified on the command line.
Please also specify `--python-sdks-folder=<path to the root directory of your azure-sdk-for-python clone>`.
Use `--python-mode=update` if you already have a setup.py and just want to update the code itself.
``` yaml $(python)
python-mode: create
python:
license-header: MICROSOFT_MIT_NO_VERSION
add-credentials: true
payload-flattening-threshold: 2
namespace: azure.cognitiveservices.search.websearch
package-name: azure-cognitiveservices-search-websearch
clear-output-folder: true
```
``` yaml $(python) && $(python-mode) == 'update'
python:
no-namespace-folders: true
output-folder: $(python-sdks-folder)/azure-cognitiveservices-search-websearch/azure/cognitiveservices/search/websearch
```
``` yaml $(python) && $(python-mode) == 'create'
python:
basic-setup-py: true
output-folder: $(python-sdks-folder)/azure-cognitiveservices-search-websearch
```
## Go
These settings apply only when `--go` is specified on the command line.
``` yaml $(go)
go:
license-header: MICROSOFT_APACHE_NO_VERSION
namespace: websearch
clear-output-folder: true
```
### Go multi-api
``` yaml $(go) && $(multiapi)
batch:
- tag: release_1_0
```
### Tag: release_1_0 and go
These settings apply only when `--tag=release_1_0 --go` is specified on the command line.
Please also specify `--go-sdk-folder=<path to the root directory of your azure-sdk-for-go clone>`.
``` yaml $(tag) == 'release_1_0' && $(go)
output-folder: $(go-sdk-folder)/services/cognitiveservices/v1.0/websearch
```
## Java
These settings apply only when `--java` is specified on the command line.
Please also specify `--azure-libraries-for-java-folder=<path to the root directory of your azure-libraries-for-java clone>`.
``` yaml $(java)
java:
azure-arm: true
namespace: com.microsoft.azure.cognitiveservices.search.websearch
license-header: MICROSOFT_MIT_NO_CODEGEN
payload-flattening-threshold: 1
output-folder: $(azure-libraries-for-java-folder)/azure-cognitiveservices/search/bingwebsearch
with-optional-parameters: true
prefix-model-type: Bing
with-single-async-method: true

# UPGRADE FROM 1.x to 2.0
## PHP requirements
* MongoDB ODM 2.0 requires PHP 7.2 or newer. If you're not running PHP 7.2 yet,
it's recommended that you upgrade to PHP 7.2 before upgrading ODM. You can use
`alcaeus/mongo-php-adapter` to use ODM 1.x with PHP 7.
* Most methods have been updated to include type hints where applicable. Please
check your extension points to make sure the function signatures are correct.
* All files in ODM 2.0 use strict typing. Please make sure to not rely on type
coercion.
## MongoDB driver change
* MongoDB ODM 2.0 now requires the new MongoDB extension, `ext-mongodb`. If
you've been using `alcaeus/mongo-php-adapter` you can remove it completely and
use ODM 2.0 directly.
* `doctrine/mongodb` is no longer used by ODM. If you've been relying on its
functionality, please update accordingly. Most utility classes from
`doctrine/mongodb` have been merged into their ODM counterparts. Classes
handling connections to MongoDB servers are being replaced by the MongoDB
library (`mongodb/mongodb`).
* The constructor signature of `Doctrine\ODM\MongoDB\DocumentManager` as well as
the `create`, `getClient`, `getDocumentDatabase`, `getDocumentCollection`, and
`getDocumentCollections` methods have been updated to handle classes from
`mongodb/mongodb` instead of `doctrine/mongodb`.
## Commands
* The `--depth` option in the `odm:query` command was dropped without
replacement.
* The `--timeout` option for all schema commands was dropped. You should use the
`--maxTimeMs` option instead.
## Aggregation builder
* The `debug` method in `Doctrine\ODM\MongoDB\Aggregation\Stage\Match` was dropped
without replacement.
## Configuration
* The `setDefaultRepositoryClassName` and `getDefaultRepositoryClassName` methods
in `Doctrine\ODM\MongoDB\Configuration` have been renamed to
`setDefaultDocumentRepositoryClassName` and
`getDefaultDocumentRepositoryClassName` respectively.
* The `setAutoGenerateProxyClasses` and `setAutoGenerateHydratorClasses` methods
no longer accept `bool` arguments. Use one of the `AUTOGENERATE_*` constants
from the `Configuration` class instead.
* The `setRetryConnect` and `setRetryQuery` methods have been dropped without
replacement. You should implement proper error handling instead of simply
re-running queries or connection attempts.
* The `AUTOGENERATE_ALWAYS` and `AUTOGENERATE_NEVER` generation strategies for
proxy objects have been removed. Use `AUTOGENERATE_EVAL` and
`AUTOGENERATE_FILE_NOT_EXISTS` instead. This does not affect hydrator or
collection generation strategies.
## Cursor changes
* Methods that previously returned a `MongoCursor` instance no longer return a
cursor directly but rather compose the cursor in iterators implementing the
`Doctrine\ODM\MongoDB\Iterator\Iterator` interface. This class provides a
`toArray` method in addition to the methods provided in PHP core's `Iterator`
interface.
* The `Doctrine\ODM\MongoDB\Cursor`, `Doctrine\ODM\MongoDB\EagerCursor`, and
`Doctrine\ODM\MongoDB\CommandCursor` classes has been dropped without
replacement. You should always use the iterator interface mentioned above in
type hints.
## Document manager
* The `flush` method in `Doctrine\ODM\MongoDB\DocumentManager` no longer takes a
`$document` as its first argument. Flushing single documents has been removed.
If you don't want to implicitly flush changes in all documents to the
database, consider using a different changeset computation strategy (e.g.
explicit).
* The `createDBRef` method has been dropped in favor of `createReference`. This
new method handles the creation of different kinds of references, not only
`DBRef`.
* The `$id` argument in `Doctrine\ODM\MongoDB\DocumentPersister::refresh` has
been dropped as it was never used.
## GridFS
GridFS support has been adapted to the new GridFS specification. The following
are no longer possible:
* Metadata must be stored in a `metadata` embedded document. Storing additional
metadata in the root document is no longer supported. If you have documents
that store metadata in the root document, migrate those documents to the new
format.
* New files are no longer persisted by flushing the DocumentManager. Instead,
they are uploaded using special methods in the new
`Doctrine\ODM\MongoDB\Repository\GridFSRepository` class.
* The mapping of GridFS files has changed significantly: GridFS files are no
longer mapped as documents but as files and there are specific annotations for
the GridFS metadata fields.
* The file's binary data can be downloaded by using special methods in the
`Doctrine\ODM\MongoDB\Repository\GridFSRepository` class. It is no longer
directly accessible from the document.
## Mapping
### General mapping changes
* The `Doctrine\ODM\MongoDB\Mapping\ClassMetadataInfo` class was dropped and its
functionality integrated into `Doctrine\ODM\MongoDB\Mapping\ClassMetadata`.
* The `safe` option for index creation has been dropped without replacement as
this is no longer applicable to current versions of MongoDB.
* Combining `repositoryMethod` with `sort` or `limit` options on inverse
references is no longer supported due to changes in the MongoDB driver.
* Repository methods used with `repositoryMethod` in inverse references now have
to return an iterator of type `Doctrine\ODM\MongoDB\Iterator\Iterator` instead
of a cursor.
* References use `dbref` as the default type when storing references instead of
`dbRefWithDB`. This omits the `$db` key in the `DBRef` object when possible.
This only has implications if you consume documents outside of ODM and require
the `$db` key to be set or if you are using multiple databases to store data.
* The `dropDups` option on indexes has been dropped without replacement since it
is no longer respected by MongoDB.
### YAML mapping
The YAML mapping drivers have been removed. Please map your documents using XML
or annotations. To migrate away from YAML mappings, first update to MongoDB ODM
1.3 and convert your mappings using the provided command.
### XML mapping
* The XML driver validates the schema before applying the mapping. If your XML
mapping file is invalid, ODM will not load it and throw an exception.
* Most mapping types now use `choice` instead of `sequence`, allowing you to map
your documents in the order you prefer.
* The `writeConcern` attribute in the `document` element has been renamed to
`write-concern` for consistency with other attributes.
* The `require-indexes` attribute in the `document` element has been dropped
without replacement.
* The `slave-okay` attribute in the `document` element has been dropped. Use the
`read-preference` element for more fine-grained read control.
* The `field` element no longer supports mapping identifiers. Use the `id`
element instead. The `id` and `id-generator-options` attributes of `field`
have been dropped in the process.
* The `file` attribute of `field` has been dropped. More information on this is
available in the GridFS update chapter.
* The `distance` attribute of `field` has been dropped without replacement. If
you've been using `geoNear` queries, you should refactor them to use the
aggregation framework and `$geoNear` pipeline operator.
* The `fieldName` attribute of the `field`, `embed-one`, `embed-many`,
`reference-one`, and `reference-many` elements has been renamed to
`field-name` for consistency.
* The `field`, `embed-one`, `embed-many`, `reference-one`, and `reference-many`
elements now support the `not-saved`, `nullable`, and `also-load` mapping
options.
* The `strategy` attribute for `embed-one` and `reference-one` has been dropped.
It was never used and does not apply to single-document relationships.
* The `cascade` element for documents now supports cascading `detach` operations
to related documents.
* The `safe` attribute of `index` has been dropped without replacement.
### Annotation mapping
* Combining `@Document`, `@EmbeddedDocument`, `@File`, `@MappedSuperclass` and
`@QueryResultDocument` annotations on a single class will result in a
`MappingException`.
* The `$safe` property in the `@Index` and `@UniqueIndesx` annotations has been
dropped without replacement.
* The following annotation classes have been dropped in favor of specifying the
`type` attribute in the `Field` annotation: `Bin`, `BinCustom`, `BinFunc`,
`BinMD5`, `BinUUID`, `BinUUIDRFC4122`, `Bool`, `Boolean`, `Collection`,
`Date`, `Float`, `Hash`, `Increment`, `Int`, `Integer`, `Key`, `ObjectId`,
`Raw`, `String`, `Timestamp`.
* The `NotSaved` annotation has been dropped in favor of the `notSaved`
attribute on the `Field` annotation. The `notSaved` attribute can also be
applied to reference and embed mappings.
* The `$name` and `$fieldName` properties in the `DiscriminatorField` annotation
class have been dropped. The field name is now passed via the default `$value`
property.
* The `Distance` annotation class has been dropped without replacement. If
you've been using `geoNear` queries, you should refactor them to use the
aggregation framework and `$geoNear` pipeline operator.
* The `DoctrineAnnotations.php` loader has been removed. You should register a
class loader in the `AnnotationRegistry` instead if you are using the ODM
without a framework integration (e.g. `doctrine/mongodb-odm-bundle`).
* The `requireIndexes` option in the `Document` annotation has been dropped
without replacement.
* The `slaveOkay` option in the `Document` annotation has been dropped. Use a
`ReadPreference` annotation for more fine-grained read control.
* The `File` annotation class is no longer a field-level annotation but now used
on a class. More information on this is available in the GridFS update
chapter.
* The `simple` option for `ReferenceOne` and `ReferenceMany` annotations has
been dropped. Use the `storeAs` option with an appropriate value instead.
* The `registerAnnotationClasses` method in
`Doctrine\ODM\MongoDB\Mapping\Driver\AnnotationDriver` has been dropped
without replacement. You should register a class loader in the
`AnnotationRegistry` instead.
### Same-namespace resolution dropped
With same-namespace resolution, the metadata driver would look for a class of
that name in the same namespace if the given class name didn't contain a
namespace separator (`\`). This is no longer supported, use fully qualified
class names or the `::class` constant instead:
```php
/**
* @ODM\Document(repositoryClass=UserRepository::class)
*/
class User
{
/**
* @ODM\ReferenceMany(targetDocument=Group::class)
*/
private $groups;
}
```
This affects the `repositoryClass` attribute in documents, `targetDocument` in
references and embedded relationships as well as class names in discriminator
maps.
## Proxy objects
The proxy implementation no longer relies on Doctrine proxies but rather
the [Proxy Manager](https://github.com/ocramius/ProxyManager) library by
ocramius. If you are checking for proxies, the following changed:
* Proxies no longer implement `Doctrine\ODM\MongoDB\Proxy\Proxy` or
any other Doctrine proxy interface. To check whether a returned object is a
proxy, check for the `ProxyManager\Proxy\GhostObjectInterface` interface.
* The `__load` method has been replaced by `initializeProxy`.
* The `__isInitialized` method has been replaced by `isProxyInitialized`.
* To resolve the original class name for a proxy object, you can no longer use
the `Doctrine\Common\Util\ClassUtils` class. Instead, fetch the class name
resolver from the document manager:
```php
$dm->getClassNameResolver()->getRealClass($className);
```
* The return value of the `getClassNameResolver` method was updated in
2.0.0. The previously returned
`Doctrine\ODM\MongoDB\Proxy\ClassNameResolver` class was dropped in favour of
the `Doctrine\ODM\MongoDB\Proxy\Resolver\ClassNameResolver` interface. This
BC break was necessary to mitigate a performance regression. The `getClass`
method was dropped from the interface as it wasn't being used.
## Repository
* The `Doctrine\ODM\MongoDB\DocumentRepository` class has been renamed to
`Doctrine\ODM\MongoDB\Repository\DocumentRepository`.
* The `findBy*` and `findOneBy*` magic methods have been dropped. Please create
explicit methods or use the `findBy` and `findOneBy` methods instead.
* The `Doctrine\ODM\MongoDB\Repository\DefaultRepositoryFactory` class has been
made `final`.
## Query
* The `requireIndexes` method in `Doctrine\ODM\MongoDB\Query\Builder` has been
dropped without replacement. If you want to require indexes for queries, use
the `notablescan` option in the MongoDB server.
* Running `geoNear` commands through the `geoNear` helper in the query builder
is no longer supported. Please refactor your queries to use the aggregation
framework and `$geoNear` pipeline operator.
* Running `group` and `mapReduce` commands through the query builder is no
longer supported. Please either refactor your queries to use the aggregation
framework or use the MongoDB library (`mongodb/mongodb`) to execute these
commands.
* The `Doctrine\ODM\MongoDB\Query\FieldExtractor` class was dropped entirely.
* The `getIterator` method in `Doctrine\ODM\MongoDB\Query\Query` returns an
iterator of type `Doctrine\ODM\MongoDB\Iterator\Iterator` instead of a MongoDB
cursor.
* The `execute` method in `Doctrine\ODM\MongoDB\Query\Query` now returns an
iterator of type `Doctrine\ODM\MongoDB\Iterator\Iterator` for find queries,
and a plain array for distinct queries.
* The `eagerCursor` helper in `Doctrine\ODM\MongoDB\Query\Builder` and its logic
have been removed entirely without replacement.
* Querying for a mapped superclass in a complex inheritance chain will now only
return children of that specific class instead of all classes in the
inheritance tree.
## Schema manager
* The schema manager no longer implicitly creates indexes covering the shard key
when sharding a collection. While MongoDB creates this index automatically
when sharding an empty collection, it is recommended users explicitly map an
index covering the shard key.
* The `createDatabases` and `createDocumentDatabases` methods have been removed
from `Doctrine\ODM\MongoDB\SchemaManager`. Databases are created implicitly in
MongoDB 3.0.
* The `--db` argument to the `odm:schema:create` console command has been
removed.
## Tools
* The `Doctrine\ODM\MongoDB\Tools\DisconnectedClassMetadataFactory` class has
been dropped without replacement.
* Document and repository generation was removed completely.
## Types
* The `Doctrine\ODM\MongoDB\Types\FileType` class was removed completely.
* The `Doctrine\ODM\MongoDB\Types\IncrementType` class was removed completely.
Use an `increment` strategy on the field mapping for `int` and `float` fields
instead.
## Unit of work
* The `commit` method in `Doctrine\ODM\MongoDB\UnitOfWork` no longer takes a
`$document` as its first argument. Flushing single documents has been removed.
If you don't want to implicitly flush changes in all documents to the
database, consider using a different changeset computation strategy (e.g.
explicit).
* Triggering a `commit` while one is already in progress will now cause an
exception. This would usually happen if you flushed the document manager from
within a lifecycle event handler. Since data integrity can't be guaranteed, it
is no longer allowed to nest flushes to the database.
* The `isScheduledForDirtyCheck` and `scheduleForDirtyCheck` methods have been
renamed to `isScheduledForSynchronization` and `scheduleForSynchronization`,
respectively.
## Internal classes and methods
Number of public methods and classes saw an `@internal` annotation added. This
marks places which are considered private to ODM but can not become ones due to
language limitations. Those methods can still be used (at your own risk) however
the backward compatibility promise for them is relaxed: we reserve the right to
change internal method's signatures and/or remove them altogether in *minor*
releases. Should such change be made, a note shall be included in the `UPGRADE.md`
file describing changes contained in the release.
## Final classes
Following classes have been made `final`:
* `Doctrine\ODM\MongoDB\DocumentNotFoundException`
* `Doctrine\ODM\MongoDB\Event\DocumentNotFoundEventArgs`
* `Doctrine\ODM\MongoDB\Event\LoadClassMetadataEventArgs`
* `Doctrine\ODM\MongoDB\Event\OnClassMetadataNotFoundEventArgs`
* `Doctrine\ODM\MongoDB\Event\OnClearEventArgs`
* `Doctrine\ODM\MongoDB\Event\OnFlushEventArgs`
* `Doctrine\ODM\MongoDB\Event\PostCollectionLoadEventArgs`
* `Doctrine\ODM\MongoDB\Event\PostFlushEventArgs`
* `Doctrine\ODM\MongoDB\Event\PreFlushEventArgs`
* `Doctrine\ODM\MongoDB\Event\PreLoadEventArgs`
* `Doctrine\ODM\MongoDB\Event\PreUpdateEventArgs`
* `Doctrine\ODM\MongoDB\Hydrator\HydratorException`
* `Doctrine\ODM\MongoDB\Hydrator\HydratorFactory`
* `Doctrine\ODM\MongoDB\Id\AlnumGenerator`
* `Doctrine\ODM\MongoDB\Id\AutoGenerator`

* `Doctrine\ODM\MongoDB\Persisters\DocumentPersister`
* `Doctrine\ODM\MongoDB\Persisters\PersistenceBuilder`
* `Doctrine\ODM\MongoDB\Proxy\Factory\StaticProxyFactory`

Inconsolata LGC
---------------
Inconsolata is one of the most suitable font for programmers created by Raph
Levien. Since the original Inconsolata does not contain Cyrillic alphabet,
it was slightly inconvenient for not a few programmers from Russia.
Inconsolata LGC is a modified version of Inconsolata with added the Cyrillic
alphabet which directly descends from Inconsolata Hellenic supporting modern
Greek.
Inconsolata LGC is licensed under SIL OFL.
Inconsolata LGC changes:
* Cyrillic glyphs added.
* Italic and Bold font added.
Changes inherited from Inconsolata Hellenic:
* Greek glyphs.
Changes inherited from Inconsolata-dz:
* Straight quotation marks.
## Which font?
### TL;DR
* Pick your font family and then select from the `'complete'` directory.
* If you are on Windows pick a font with the `'Windows Compatible'` suffix.
* This includes specific tweaks to ensure the font works on Windows, in particular monospace identification and font name length limitations
* If you are limited to monospaced fonts (because of your terminal, etc) then pick a font with the `'Mono'` suffix.
* This denotes that the Nerd Font glyphs will be monospaced not necessarily that the entire font will be monospaced
### Ligatures
By the *Nerd Font* policy, the variant with the `'Mono'` suffix is not supposed to have any ligatures.
Use the non-*Mono* variants to have ligatures.
### Explanation
Once you narrow down your font choice of family (`Droid Sans`, `Inconsolata`, etc) and style (`bold`, `italic`, etc) you have 2 main choices:
#### `Option 1: Download already patched font`
* download an already patched font from the `complete` folder
* This is most likely the one you want. It includes **all** of the glyphs from all of the glyph sets. Only caution here is that some fonts have glyphs in the _same_ code point so to include everything some had to be moved to alternate code points.
#### `Option 2: Patch your own font`
* patch your own variations with the various options provided by the font patcher (see each font's readme for full list of combinations available)
* This is the option you want if the font you use is _not_ already included or you want maximum control of what's included
* This contains a list of _all permutations_ of the various glyphs. E.g. You want the font with only [Octicons][octicons] or you want the font with just [Font Awesome][font-awesome] and [Devicons][vorillaz-devicons]. The goal is to provide every combination possible in this folder.
For more information see: [The FAQ](https://github.com/ryanoasis/nerd-fonts/wiki/FAQ-and-Troubleshooting#which-font)

## Variations (Combinations)
> The combinations and total number of combinations are provided here for reference if you want to create your own variation of a patched Nerd Font.
### Why aren't all variations included ?
Combinations are no longer included by default because of the large inflation in size it caused the Repository _and_ the amount of time it takes to rebuild all of the combinations. This issue would exponentially get worse as the numbers of Fonts and Glyph Sets provided increase.
