skipped. 'optimize' must be one of the following:
0 - don't optimize
1 - normal optimization (like "python -O")
2 - extra optimization (like "python -OO")
If 'force' is true, all files are recompiled regardless of
timestamps.
The source filename encoded in each bytecode file defaults to the
filenames listed in 'py_files'; you can modify these with 'prefix' and
'basedir'. 'prefix' is a string that will be stripped off of each
source filename, and 'base_dir' is a directory name that will be
prepended (after 'prefix' is stripped). You can supply either or both
(or neither) of 'prefix' and 'base_dir', as you wish.
If 'dry_run' is true, doesn't actually do anything that would
affect the filesystem.
Byte-compilation is either done directly in this interpreter process
with the standard py_compile module, or indirectly by writing a
temporary script and executing it. Normally, you should let
'byte_compile()' figure out to use direct compilation or not (see
the source for details). The 'direct' flag is used by the script
generated in indirect mode; unless you know what you're doing, leave
it set to None.

A dictionary-like object that uses the keys as bounds for a range.
Inclusion of the value for that range is determined by the

A value is returned for a key if it is the first key that matches in
the sorted list of keys.
One may supply keyword parameters to be passed to the sort function used
to sort keys (i.e. key, reverse) as sort_params.
Let's create a map that maps 1-3 -> 'a', 4-6 -> 'b'
>>> r = RangeMap({3: 'a', 6: 'b'}) # boy, that was easy
>>> r[1], r[2], r[3], r[4], r[5], r[6]

Even float values should work so long as the comparison operator
supports it.
>>> r[4.5]
'b'
But you'll notice that the way rangemap is defined, it must be open-ended
on one side.
>>> r[0]
'a'
>>> r[-1]
'a'
One can close the open-end of the RangeMap by using undefined_value
>>> r = RangeMap({0: RangeMap.undefined_value, 3: 'a', 6: 'b'})
>>> r[0]
Traceback (most recent call last):
...
KeyError: 0
One can get the first or last elements in the range by using RangeMap.Item
>>> last_item = RangeMap.Item(-1)
>>> r[last_item]
'b'
.last_item is a shortcut for Item(-1)
>>> r[RangeMap.last_item]
'b'
Sometimes it's useful to find the bounds for a RangeMap
>>> r.bounds()
(0, 6)
RangeMap supports .get(key, default)
>>> r.get(0, 'not found')
'not found'
>>> r.get(7, 'not found')
'not found'
One often wishes to define the ranges by their left-most values,
which requires use of sort params and a key_match_comparator.
>>> r = RangeMap({1: 'a', 4: 'b'},
... sort_params=dict(reverse=True),
... key_match_comparator=operator.ge)
>>> r[1], r[2], r[3], r[4], r[5], r[6]

is provided:

module and everything needed to build it (hopefully in a portable
way, but there are hooks that let you be as unportable as you need).
Instance attributes:
name : string
the full name of the extension, including any packages -- ie.
*not* a filename or pathname, but Python dotted name
sources : [string]
list of source filenames, relative to the distribution root
(where the setup script lives), in Unix form (slash-separated)
for portability. Source files may be C, C++, SWIG (.i),
platform-specific resource files, or whatever else is recognized
by the "build_ext" command as source for a Python extension.
include_dirs : [string]
list of directories to search for C/C++ header files (in Unix
form for portability)
define_macros : [(name : string, value : string|None)]
list of macros to define; each macro is defined using a 2-tuple,
where 'value' is either the string to define it to or None to
define it without a particular value (equivalent of "#define
FOO" in source or -DFOO on Unix C compiler command line)
undef_macros : [string]
list of macros to undefine explicitly
library_dirs : [string]
list of directories to search for C/C++ libraries at link time
libraries : [string]
list of library names (not filenames or paths) to link against
runtime_library_dirs : [string]
list of directories to search for C/C++ libraries at run time
(for shared extensions, this is when the extension is loaded)
extra_objects : [string]
list of extra files to link with (eg. object files not implied
by 'sources', static library that must be explicitly specified,
binary resource files, etc.)
extra_compile_args : [string]
any extra platform- and compiler-specific information to use
when compiling the source files in 'sources'. For platforms and
compilers where "command line" makes sense, this is typically a
list of command-line arguments, but for other platforms it could
be anything.
extra_link_args : [string]
any extra platform- and compiler-specific information to use
when linking object files together to create the extension (or

interpretation as for 'extra_compile_args'.
export_symbols : [string]
list of symbols to be exported from a shared extension. Not
used on all platforms, and not generally necessary for Python
extensions, which typically export exactly one symbol: "init" +
extension_name.
swig_opts : [string]
any extra options to pass to SWIG if a source file has the .i
extension.
depends : [string]
list of files that the extension depends on
language : string
extension language (i.e. "c", "c++", "objc"). Will be detected
from the source extensions if not provided.
optional : boolean
specifies that a build failure in the extension should not abort the
build process, but simply not install the failing extension.

# end class StrictVersion
# The rules according to Greg Stein:
# 1) a version number has 1 or more numbers separated by a period or by
# sequences of letters. If only periods, then these are compared
# left-to-right to determine an ordering.
# 2) sequences of letters are part of the tuple for comparison and are
# compared lexicographically
# 3) recognize the numeric components may have leading zeroes
#
# The LooseVersion class below implements these rules: a version number
# string is split up into a tuple of integer and string components, and
# comparison is a simple tuple comparison. This means that version
# numbers behave in a predictable and obvious way, but a way that might
# not necessarily be how people *want* version numbers to behave. There
# wouldn't be a problem if people could stick to purely numeric version
# numbers: just split on period and compare the numbers as tuples.
# However, people insist on putting letters into their version numbers;
# the most common purpose seems to be:
# - indicating a "pre-release" version
# ('alpha', 'beta', 'a', 'b', 'pre', 'p')
# - indicating a post-release patch ('p', 'pl', 'patch')
# but of course this can't cover all version number schemes, and there's
# no way to know what a programmer means without asking him.
#
# The problem is what to do with letters (and other non-numeric
# characters) in a version number. The current implementation does the
# obvious and predictable thing: keep them as strings and compare
# lexically within a tuple comparison. This has the desired effect if
# an appended letter sequence implies something "post-release":
# eg. "0.99" < "0.99pl14" < "1.0", and "5.001" < "5.001m" < "5.002".
#
# However, if letters in a version number imply a pre-release version,
# the "obvious" thing isn't correct. Eg. you would expect that
# "1.5.1" < "1.5.2a2" < "1.5.2", but under the tuple/lexical comparison
# implemented here, this just isn't so.
#
# Two possible solutions come to mind. The first is to tie the
# comparison algorithm to a particular set of semantic rules, as has
# been done in the StrictVersion class above. This works great as long
# as everyone can go along with bondage and discipline. Hopefully a
# (large) subset of Python module programmers will agree that the
# particular flavour of bondage and discipline provided by StrictVersion
# provides enough benefit to be worth using, and will submit their
# version numbering scheme to its domination. The free-thinking
# anarchists in the lot will never give in, though, and something needs
# to be done to accommodate them.
#
# Perhaps a "moderately strict" version class could be implemented that
# lets almost anything slide (syntactically), and makes some heuristic
# assumptions about non-digits in version number strings. This could
# sink into special-case-hell, though; if I was as talented and
# idiosyncratic as Larry Wall, I'd go ahead and implement a class that
# somehow knows that "1.2.1" < "1.2.2a2" < "1.2.2" < "1.2.2pl3", and is
# just as happy dealing with things like "2g6" and "1.13++". I don't
# think I'm smart enough to do it right though.
#
# In any case, I've coded the test suite for this module (see
# ../test/test_version.py) specifically to fail on things like comparing
# "1.2a2" and "1.2". That's not because the *code* is doing anything
# wrong, it's because the simple, obvious design doesn't match my
# complicated, hairy expectations for real-world version numbers. It
# would be a snap to fix the test suite to say, "Yep, LooseVersion does
# the Right Thing" (ie. the code matches the conception). But I'd rather
# have a conception that matches common notions about version numbers.

provides the TextFile class, which gives an interface to text files
that (optionally) takes care of stripping comments, ignoring blank
lines, and joining lines with backslashes."""
import sys
class TextFile:
"""Provides a file-like object that takes care of all the things you
commonly want to do when processing a text file that has some
line-by-line syntax: strip comments (as long as "#" is your
comment character), skip blank lines, join adjacent lines by
escaping the newline (ie. backslash at end of line), strip
leading and/or trailing whitespace. All of these are optional
and independently controllable.
Provides a 'warn()' method so you can generate warning messages that
report physical line number, even if the logical line in question
spans multiple physical lines. Also provides 'unreadline()' for
implementing line-at-a-time lookahead.
Constructor is called as:
TextFile (filename=None, file=None, **options)
It bombs (RuntimeError) if both 'filename' and 'file' are None;
'filename' should be a string, and 'file' a file object (or
something that provides 'readline()' and 'close()' methods). It is
recommended that you supply at least 'filename', so that TextFile
can include it in warning messages. If 'file' is not supplied,
TextFile creates its own using 'io.open()'.
The options are all boolean, and affect the value returned by
'readline()':
strip_comments [default: true]
strip from "#" to end-of-line, as well as any whitespace
leading up to the "#" -- unless it is escaped by a backslash
lstrip_ws [default: false]
strip leading whitespace from each line before returning it
rstrip_ws [default: true]
strip trailing whitespace (including line terminator!) from
each line before returning it
skip_blanks [default: true}
skip lines that are empty *after* stripping comments and
whitespace. (If both lstrip_ws and rstrip_ws are false,
then some lines may consist of solely whitespace: these will
*not* be skipped, even if 'skip_blanks' is true.)
join_lines [default: false]
if a backslash is the last non-newline character on a line
after stripping comments and whitespace, join the following line
to it to form one "logical line"; if N consecutive lines end
with a backslash, then N+1 physical lines will be joined to
form one logical line.
collapse_join [default: false]
strip leading whitespace from lines that are joined to their
predecessor; only matters if (join_lines and not lstrip_ws)
errors [default: 'strict']
error handler used to decode the file content
Note that since 'rstrip_ws' can strip the trailing newline, the
semantics of 'readline()' must differ from those of the builtin file
object's 'readline()' method! In particular, 'readline()' returns
None for end-of-file: an empty string might just be a blank line (or
an all-whitespace line), if 'rstrip_ws' is true but 'skip_blanks' is
not."""

Parameter specification variables exist primarily for the benefit of static

or s the first argument to ``Callable``. In Python 3.10 and higher,
they are also supported in user-defined Generics at runtime.

example for annotating a decorator::

Parameter specification variables defined with covariant=True or
contravariant=True can be used to declare covariant or contravariant
generic types. These keyword arguments are valid, but their actual semantics
are yet to be decided. See PEP 612 for details.
Parameter specification variables can be introspected. e.g.:
P.__name__ == 'T'
P.__bound__ == None
P.__covariant__ == False
P.__contravariant__ == False

definition. This can augment what the function returns without changing the
function's code.
For example, to produce a decorator version of :func:`chunked`:
>>> from more_itertools import chunked
>>> chunker = make_decorator(chunked, result_index=0)
>>> @chunker(3)
... def iter_range(n):
... return iter(range(n))
...
>>> list(iter_range(9))
[[0, 1, 2], [3, 4, 5], [6, 7, 8]]
To only allow truthy items to be returned:
>>> truth_serum = make_decorator(filter, result_index=1)
>>> @truth_serum(bool)
... def boolean_test():
... return [0, 1, '', ' ', False, True]
...
>>> list(boolean_test())
[1, ' ', True]
The :func:`peekable` and :func:`seekable` wrappers make for practical
decorators:
>>> from more_itertools import peekable
>>> peekable_function = make_decorator(peekable)
>>> @peekable_function()
... def str_range(*args):
... return (str(x) for x in range(*args))
...
>>> it = str_range(1, 20, 2)
>>> next(it), next(it), next(it)
('1', '3', '5')
>>> it.peek()
'7'
>>> next(it)
'7'

"""
Wrap lru_cache to support storing the cache data in the object instances.
Abstracts the common paradigm where the method explicitly saves an
underscore-prefixed protected property on first call and returns that
subsequently.

>>> a = MyClass()

3
>>> for x in range(75):
... res = a.method(x)
>>> a.calls
75
Note that the apparent behavior will be exactly like that of lru_cache
except that the cache is stored on each instance, so values in one
instance will not flush values from another, and when an instance is
deleted, so are the cached values for that instance.
>>> b = MyClass()
>>> for x in range(35):
... res = b.method(x)
>>> b.calls
35
>>> a.method(0)
0
>>> a.calls
75
Note that if method had been decorated with ``functools.lru_cache()``,
a.calls would have been 76 (due to the cached value of 0 having been
flushed by the 'b' instance).
Clear the cache with ``.cache_clear()``
>>> a.method.cache_clear()
Same for a method that hasn't yet been called.

Caution - do not subsequently wrap the method with another decorator, such

a.calls would have been 76 (due to the cached value of 0 having been

Call a function for its side effect after initialization.
The benefit of using the decorator instead of simply invoking a function
after defining it is that it makes explicit the author's intent for the
function to be called immediately. Whereas if one simply calls the
function immediately, it's less obvious if that was intentional or
incidental. It also avoids repeating the name - the two actions, defining
the function and calling it immediately are modeled separately, but linked
by the decorator construct.
The benefit of having a function construct (opposed to just invoking some
behavior inline) is to serve as a scope in which the behavior occurs. It
avoids polluting the global namespace with local variables, provides an
anchor on which to attach documentation (docstring), keeps the behavior
logically separated (instead of conceptually separated or not separated at
all), and provides potential to re-use the behavior for testing or other
purposes.
This function is named as a pithy way to communicate, "call this function
primarily for its side effect", or "while defining this function, also
take it aside and call it". It exists because there's no Python construct
for "define and call" (nor should there be, as decorators serve this need
just fine). The behavior happens immediately and synchronously.
