// Environment-describing macros
// -----------------------------
//
// Google Test can be used in many different environments. Macros in
// this section tell Google Test what kind of environment it is being
// used in, such that Google Test can provide environment-specific
// features and implementations.
//
// Google Test tries to automatically detect the properties of its
// environment, so users usually don't need to worry about these
// macros. However, the automatic detection is not perfect.
// Sometimes it's necessary for a user to define some of the following
// macros in the build script to override Google Test's decisions.
//
// If the user doesn't define a macro in the list, Google Test will
// provide a default definition. After this header is #included, all
// macros in this list will be defined to either 1 or 0.
//
// Notes to maintainers:
// - Each macro here is a user-tweakable knob; do not grow the list
// lightly.
// - Use #if to key off these macros. Don't use #ifdef or "#if
// defined(...)", which will not work as these macros are ALWAYS
// defined.
//
// GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
// is/isn't available.
// GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
// are enabled.
// GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::string, which is different to std::string).
// GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::string
// is/isn't available (some systems define
// ::wstring, which is different to std::wstring).
// GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
// expressions are/aren't available.
// GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
// is/isn't available.
// GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
// enabled.
// GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
// std::wstring does/doesn't work (Google Test can
// be used where std::wstring is unavailable).
// GTEST_HAS_TR1_TUPLE - Define it to 1/0 to indicate tr1::tuple
// is/isn't available.
// GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
// compiler supports Microsoft's "Structured
// Exception Handling".
// GTEST_HAS_STREAM_REDIRECTION
// - Define it to 1/0 to indicate whether the
// platform supports I/O stream redirection using
// dup() and dup2().
// GTEST_USE_OWN_TR1_TUPLE - Define it to 1/0 to indicate whether Google
// Test's own tr1 tuple implementation should be
// used. Unused when the user sets
// GTEST_HAS_TR1_TUPLE to 0.
// GTEST_LANG_CXX11 - Define it to 1/0 to indicate that Google Test
// is building in C++11/C++98 mode.
// GTEST_LINKED_AS_SHARED_LIBRARY
// - Define to 1 when compiling tests that use
// Google Test as a shared library (known as
// DLL on Windows).
// GTEST_CREATE_SHARED_LIBRARY
// - Define to 1 when compiling Google Test itself
// as a shared library.
// Platform-indicating macros
// --------------------------
//
// Macros indicating the platform on which Google Test is being used
// (a macro is defined to 1 if compiled on the given platform;
// otherwise UNDEFINED -- it's never defined to 0.). Google Test
// defines these macros automatically. Code outside Google Test MUST
// NOT define them.
//
// GTEST_OS_AIX - IBM AIX
// GTEST_OS_CYGWIN - Cygwin
// GTEST_OS_FREEBSD - FreeBSD
// GTEST_OS_HPUX - HP-UX
// GTEST_OS_LINUX - Linux
// GTEST_OS_LINUX_ANDROID - Google Android
// GTEST_OS_MAC - Mac OS X
// GTEST_OS_IOS - iOS
// GTEST_OS_NACL - Google Native Client (NaCl)
// GTEST_OS_OPENBSD - OpenBSD
// GTEST_OS_QNX - QNX
// GTEST_OS_SOLARIS - Sun Solaris
// GTEST_OS_SYMBIAN - Symbian
// GTEST_OS_WINDOWS - Windows (Desktop, MinGW, or Mobile)
// GTEST_OS_WINDOWS_DESKTOP - Windows Desktop
// GTEST_OS_WINDOWS_MINGW - MinGW
// GTEST_OS_WINDOWS_MOBILE - Windows Mobile
// GTEST_OS_WINDOWS_PHONE - Windows Phone
// GTEST_OS_WINDOWS_RT - Windows Store App/WinRT
// GTEST_OS_ZOS - z/OS
//
// Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
// most stable support. Since core members of the Google Test project
// don't have access to other platforms, support for them may be less
// stable. If you notice any problems on your platform, please notify
// [email protected] (patches for fixing them are
// even more welcome!).
//
// It is possible that none of the GTEST_OS_* macros are defined.
// Feature-indicating macros
// -------------------------
//
// Macros indicating which Google Test features are available (a macro
// is defined to 1 if the corresponding feature is supported;
// otherwise UNDEFINED -- it's never defined to 0.). Google Test
// defines these macros automatically. Code outside Google Test MUST
// NOT define them.
//
// These macros are public so that portable tests can be written.
// Such tests typically surround code using a feature with an #if
// which controls that code. For example:
//
// #if GTEST_HAS_DEATH_TEST
// EXPECT_DEATH(DoSomethingDeadly());
// #endif
//
// GTEST_HAS_COMBINE - the Combine() function (for value-parameterized
// tests)
// GTEST_HAS_DEATH_TEST - death tests
// GTEST_HAS_PARAM_TEST - value-parameterized tests
// GTEST_HAS_TYPED_TEST - typed tests
// GTEST_HAS_TYPED_TEST_P - type-parameterized tests
// GTEST_IS_THREADSAFE - Google Test is thread-safe.
// GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
// GTEST_HAS_POSIX_RE (see above) which users can
// define themselves.
// GTEST_USES_SIMPLE_RE - our own simple regex is used;
// the above two are mutually exclusive.
// GTEST_CAN_COMPARE_NULL - accepts untyped NULL in EXPECT_EQ().
// Misc public macros
// ------------------
//
// GTEST_FLAG(flag_name) - references the variable corresponding to
// the given Google Test flag.
// Internal utilities
// ------------------
//
// The following macros and utilities are for Google Test's INTERNAL
// use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
//
// Macros for basic C++ coding:
// GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
// GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
// variable don't have to be used.
// GTEST_DISALLOW_ASSIGN_ - disables operator=.
// GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
// GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
// GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
// suppressed (constant conditional).
// GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
// is suppressed.
//
// C++11 feature wrappers:
//
// testing::internal::move - portability wrapper for std::move.
//
// Synchronization:
// Mutex, MutexLock, ThreadLocal, GetThreadCount()
// - synchronization primitives.
//
// Template meta programming:
// is_pointer - as in TR1; needed on Symbian and IBM XL C/C++ only.
// IteratorTraits - partial implementation of std::iterator_traits, which
// is not available in libCstd when compiled with Sun C++.
//
// Smart pointers:
// scoped_ptr - as in TR2.
//
// Regular expressions:
// RE - a simple regular expression class using the POSIX
// Extended Regular Expression syntax on UNIX-like
// platforms, or a reduced regular exception syntax on
// other platforms, including Windows.
//
// Logging:
// GTEST_LOG_() - logs messages at the specified severity level.
// LogToStderr() - directs all log messages to stderr.
// FlushInfoLog() - flushes informational log messages.
//
// Stdout and stderr capturing:
// CaptureStdout() - starts capturing stdout.
// GetCapturedStdout() - stops capturing stdout and returns the captured
// string.
// CaptureStderr() - starts capturing stderr.
// GetCapturedStderr() - stops capturing stderr and returns the captured
// string.

// We don't want to require the users to write TypesN<...> directly,
// as that would require them to count the length. Types<...> is much
// easier to write, but generates horrible messages when there is a
// compiler error, as gcc insists on printing out each template
// argument, even if it has the default value (this means Types<int>
// will appear as Types<int, None, None, ..., None> in the compiler
// errors).
//
// Our solution is to combine the best part of the two approaches: a
// user would write Types<T1, ..., TN>, and Google Test will translate
// that to TypesN<T1, ..., TN> internally to make error messages
// readable. The translation is done by the 'type' member of the
// Types template.

// We don't want to require the users to write TemplatesN<...> directly,
// as that would require them to count the length. Templates<...> is much
// easier to write, but generates horrible messages when there is a
// compiler error, as gcc insists on printing out each template
// argument, even if it has the default value (this means Templates<list>
// will appear as Templates<list, NoneT, NoneT, ..., NoneT> in the compiler
// errors).
//
// Our solution is to combine the best part of the two approaches: a
// user would write Templates<T1, ..., TN>, and Google Test will translate
// that to TemplatesN<T1, ..., TN> internally to make error messages
// readable. The translation is done by the 'type' member of the
// Templates template.

// Parameters:
// statement - A statement that a macro such as EXPECT_DEATH would test

// parameter iff EXPECT_DEATH compiles with it.
// regex - A regex that a macro such as EXPECT_DEATH would use to test
// the output of statement. This parameter has to be
// compiled but not evaluated by this macro, to ensure that
// this macro only accepts expressions that a macro such as
// EXPECT_DEATH would accept.
// terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
// and a return statement for ASSERT_DEATH_IF_SUPPORTED.
// This ensures that ASSERT_DEATH_IF_SUPPORTED will not
// compile inside functions where ASSERT_DEATH doesn't
// compile.

// The following macros are useful for writing death tests.
// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
// executed:
//
// 1. It generates a warning if there is more than one active
// thread. This is because it's safe to fork() or clone() only
// when there is a single thread.
//
// 2. The parent process clone()s a sub-process and runs the death
// test in it; the sub-process exits with code 0 at the end of the
// death test, if it hasn't exited already.
//
// 3. The parent process waits for the sub-process to terminate.
//
// 4. The parent process checks the exit code and error message of
// the sub-process.
//
// Examples:
//
// ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
// for (int i = 0; i < 5; i++) {
// EXPECT_DEATH(server.ProcessRequest(i),
// "Invalid request .* in ProcessRequest()")
// << "Failed to die on request " << i;
// }
//
// ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
//
// bool KilledBySIGHUP(int exit_code) {
// return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
// }
//
// ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
//
// On the regular expressions used in death tests:
//
// On POSIX-compliant systems (*nix), we use the <regex.h> library,
// which uses the POSIX extended regex syntax.
//
// On other platforms (e.g. Windows), we only support a simple regex
// syntax implemented as part of Google Test. This limited
// implementation should be enough most of the time when writing
// death tests; though it lacks many features you can find in PCRE
// or POSIX extended regex syntax. For example, we don't support
// union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
// repetition count ("x{5,7}"), among others.
//
// Below is the syntax that we do support. We chose it to be a
// subset of both PCRE and POSIX extended regex, so it's easy to
// learn wherever you come from. In the following: 'A' denotes a
// literal character, period (.), or a single \\ escape sequence;
// 'x' and 'y' denote regular expressions; 'm' and 'n' are for
// natural numbers.
//
// c matches any literal character c
// \\d matches any decimal digit
// \\D matches any character that's not a decimal digit
// \\f matches \f
// \\n matches \n
// \\r matches \r
// \\s matches any ASCII whitespace, including \n
// \\S matches any character that's not a whitespace
// \\t matches \t
// \\v matches \v
// \\w matches any letter, _, or decimal digit
// \\W matches any character that \\w doesn't match
// \\c matches any literal character c, which must be a punctuation
// . matches any single character except \n
// A? matches 0 or 1 occurrences of A
// A* matches 0 or many occurrences of A
// A+ matches 1 or many occurrences of A
// ^ matches the beginning of a string (not that of each line)
// $ matches the end of a string (not that of each line)
// xy matches x followed by y
//
// If you accidentally use PCRE or POSIX extended regex features
// not implemented by us, you will get a run-time failure. In that
// case, please try to rewrite your regular expression within the
// above syntax.
//
// This implementation is *not* meant to be as highly tuned or robust
// as a compiled regex library, but should perform well enough for a
// death test, which already incurs significant overhead by launching
// a child process.
//
// Known caveats:
//
// A "threadsafe" style death test obtains the path to the test
// program from argv[0] and re-executes it in the sub-process. For
// simplicity, the current implementation doesn't search the PATH
// when launching the sub-process. This means that the user must
// invoke the test program via a path that contains at least one
// path separator (e.g. path/to/foo_test and
// /absolute/path/to/bar_test are fine, but foo_test is not). This
// is rarely a problem as people usually don't put the test binary
// directory in PATH.
//
// TODO([email protected]): make thread-safe death tests search the PATH.

// Value-parameterized tests allow you to test your code with different
// parameters without writing multiple copies of the same test.
//
// Here is how you use value-parameterized tests:
#if 0
// To write value-parameterized tests, first you should define a fixture
// class. It is usually derived from testing::TestWithParam<T> (see below for
// another inheritance scheme that's sometimes useful in more complicated
// class hierarchies), where the type of your parameter values.
// TestWithParam<T> is itself derived from testing::Test. T can be any
// copyable type. If it's a raw pointer, you are responsible for managing the
// lifespan of the pointed values.
class FooTest : public ::testing::TestWithParam<const char*> {
// You can implement all the usual class fixture members here.
};
// Then, use the TEST_P macro to define as many parameterized tests
// for this fixture as you want. The _P suffix is for "parameterized"
// or "pattern", whichever you prefer to think.
TEST_P(FooTest, DoesBlah) {
// Inside a test, access the test parameter with the GetParam() method
// of the TestWithParam<T> class:
EXPECT_TRUE(foo.Blah(GetParam()));
...
}
TEST_P(FooTest, HasBlahBlah) {
...
}
// Finally, you can use INSTANTIATE_TEST_CASE_P to instantiate the test
// case with any set of parameters you want. Google Test defines a number
// of functions for generating test parameters. They return what we call
// (surprise!) parameter generators. Here is a summary of them, which
// are all in the testing namespace:
//
//
// Range(begin, end [, step]) - Yields values {begin, begin+step,
// begin+step+step, ...}. The values do not
// include end. step defaults to 1.
// Values(v1, v2, ..., vN) - Yields values {v1, v2, ..., vN}.
// ValuesIn(container) - Yields values from a C-style array, an STL
// ValuesIn(begin,end) container, or an iterator range [begin, end).
// Bool() - Yields sequence {false, true}.
// Combine(g1, g2, ..., gN) - Yields all combinations (the Cartesian product
// for the math savvy) of the values generated
// by the N generators.
//
// For more details, see comments at the definitions of these functions below
// in this file.
//
// The following statement will instantiate tests from the FooTest test case
// each with parameter values "meeny", "miny", and "moe".
INSTANTIATE_TEST_CASE_P(InstantiationName,
FooTest,
Values("meeny", "miny", "moe"));
// To distinguish different instances of the pattern, (yes, you
// can instantiate it more then once) the first argument to the
// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
// actual test case name. Remember to pick unique prefixes for different
// instantiations. The tests from the instantiation above will have
// these names:
//
// * InstantiationName/FooTest.DoesBlah/0 for "meeny"
// * InstantiationName/FooTest.DoesBlah/1 for "miny"
// * InstantiationName/FooTest.DoesBlah/2 for "moe"
// * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
// * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
// * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
//
// You can use these names in --gtest_filter.
//
// This statement will instantiate all tests from FooTest again, each
// with parameter values "cat" and "dog":
const char* pets[] = {"cat", "dog"};
INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
// The tests from the instantiation above will have these names:
//
// * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
// * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
// * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
// * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
//
// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
// in the given test case, whether their definitions come before or
// AFTER the INSTANTIATE_TEST_CASE_P statement.
//
// Please also note that generator expressions (including parameters to the
// generators) are evaluated in InitGoogleTest(), after main() has started.
// This allows the user on one hand, to adjust generator parameters in order
// to dynamically determine a set of tests to run and on the other hand,
// give the user a chance to inspect the generated tests with Google Test
// reflection API before RUN_ALL_TESTS() is executed.
//
// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
// for more examples.
//
// In the future, we plan to publish the API for defining new parameter
// generators. But for now this interface remains part of the internal
// implementation and is subject to change.
//
//
// A parameterized test fixture must be derived from testing::Test and from
// testing::WithParamInterface<T>, where T is the type of the parameter
// values. Inheriting from TestWithParam<T> satisfies that requirement because
// TestWithParam<T> inherits from both Test and WithParamInterface. In more
// complicated hierarchies, however, it is occasionally useful to inherit
// separately from Test and WithParamInterface. For example:
class BaseTest : public ::testing::Test {
// You can inherit all the usual members for a non-parameterized test
// fixture here.
};
class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
// The usual test fixture members go here too.
};
TEST_F(BaseTest, HasFoo) {
// This is an ordinary non-parameterized test.
}
TEST_P(DerivedTest, DoesBlah) {
// GetParam works just the same here as if you inherit from TestWithParam.
EXPECT_TRUE(foo.Blah(GetParam()));

// A "smart" pointer type with reference tracking. Every pointer to a
// particular object is kept on a circular linked list. When the last pointer
// to an object is destroyed or reassigned, the object is deleted.
//
// Used properly, this deletes the object when the last reference goes away.
// There are several caveats:
// - Like all reference counting schemes, cycles lead to leaks.
// - Each smart pointer is actually two pointers (8 bytes instead of 4).
// - Every time a pointer is assigned, the entire list of pointers to that
// object is traversed. This class is therefore NOT SUITABLE when there
// will often be more than two or three pointers to a particular object.
// - References are only tracked as long as linked_ptr<> objects are copied.
// If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
// will happen (double deletion).
//
// A good use of this class is storing object references in STL containers.
// You can safely put linked_ptr<> in a vector<>.
// Other uses may not be as good.
//
// Note: If you use an incomplete type with linked_ptr<>, the class
// *containing* linked_ptr<> must have a constructor and destructor (even
// if they do nothing!).
//
// Bill Gibbons suggested we use something like this.
//
// Thread Safety:
// Unlike other linked_ptr implementations, in this implementation
// a linked_ptr object is thread-safe in the sense that:
// - it's safe to copy linked_ptr objects concurrently,
// - it's safe to copy *from* a linked_ptr and read its underlying
// raw pointer (e.g. via get()) concurrently, and
// - it's safe to write to two linked_ptrs that point to the same
// shared object concurrently.
// TODO([email protected]): rename this to safe_linked_ptr to avoid
// confusion with normal linked_ptr.

// This file implements a universal value printer that can print a
// value of any type T:
//
// void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
//
// A user can teach this function how to print a class type T by
// defining either operator<<() or PrintTo() in the namespace that
// defines T. More specifically, the FIRST defined function in the
// following list will be used (assuming T is defined in namespace
// foo):
//
// 1. foo::PrintTo(const T&, ostream*)
// 2. operator<<(ostream&, const T&) defined in either foo or the
// global namespace.
//
// If none of the above is defined, it will print the debug string of
// the value if it is a protocol buffer, or print the raw bytes in the
// value otherwise.
//
// To aid debugging: when T is a reference type, the address of the
// value is also printed; when T is a (const) char pointer, both the
// pointer value and the NUL-terminated string it points to are
// printed.
//
// We also provide some convenient wrappers:
//
// // Prints a value to a string. For a (const or not) char
// // pointer, the NUL-terminated string (but not the pointer) is
// // printed.
// std::string ::testing::PrintToString(const T& value);
//
// // Prints a value tersely: for a reference type, the referenced
// // value (but not the address) is printed; for a (const or not) char
// // pointer, the NUL-terminated string (but not the pointer) is
// // printed.
// void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
//
// // Prints value using the type inferred by the compiler. The difference
// // from UniversalTersePrint() is that this function prints both the
// // pointer and the NUL-terminated string for a (const or not) char pointer.
// void ::testing::internal::UniversalPrint(const T& value, ostream*);
//
// // Prints the fields of a tuple tersely to a string vector, one
// // element for each field. Tuple support must be enabled in
// // gtest-port.h.
// std::vector<string> UniversalTersePrintTupleFieldsToStrings(
// const Tuple& value);
//
// Known limitation:
//
// The print primitives print the elements of an STL-style container
// using the compiler-inferred type of *iter where iter is a
// const_iterator of the container. When const_iterator is an input
// iterator but not a forward iterator, this inferred type may not
// match value_type, and the print output may be incorrect. In
// practice, this is rarely a problem as for most containers
// const_iterator is a forward iterator. We'll fix this if there's an
// actual need for it. Note that this fix cannot rely on value_type
// being defined as many user-defined container types don't have
// value_type.

// Combine() allows the user to combine two or more sequences to produce
// values of a Cartesian product of those sequences' elements.
//
// Synopsis:
// Combine(gen1, gen2, ..., genN)
// - returns a generator producing sequences with elements coming from
// the Cartesian product of elements from the sequences generated by
// gen1, gen2, ..., genN. The sequence elements will have a type of
// tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
// of elements from sequences produces by gen1, gen2, ..., genN.
//
// Combine can have up to 10 arguments. This number is currently limited
// by the maximum number of elements in the tuple implementation used by Google
// Test.
//
// Example:
//
// This will instantiate tests in test case AnimalTest each one with
// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
// tuple("dog", BLACK), and tuple("dog", WHITE):
//
// enum Color { BLACK, GRAY, WHITE };
// class AnimalTest
// : public testing::TestWithParam<tuple<const char*, Color> > {...};
//
// TEST_P(AnimalTest, AnimalLooksNice) {...}
//
// INSTANTIATE_TEST_CASE_P(AnimalVariations, AnimalTest,
// Combine(Values("cat", "dog"),
// Values(BLACK, WHITE)));
//
// This will instantiate tests in FlagDependentTest with all variations of two
// Boolean flags:
//
// class FlagDependentTest
// : public testing::TestWithParam<tuple<bool, bool> > {
// virtual void SetUp() {
// // Assigns external_flag_1 and external_flag_2 values from the tuple.
// tie(external_flag_1, external_flag_2) = GetParam();
// }
// };
//
// TEST_P(FlagDependentTest, TestFeature1) {
// // Test your code using external_flag_1 and external_flag_2 here.
// }
// INSTANTIATE_TEST_CASE_P(TwoBoolSequence, FlagDependentTest,
// Combine(Bool(), Bool()));

// Typed (aka type-driven) tests repeat the same test for types in a

template <typename T>

public:
...

// repeated for each type in the list. The typedef is necessary for
// the macro to parse correctly.
typedef testing::Types<char, int, unsigned int> MyTypes;
TYPED_TEST_CASE(FooTest, MyTypes);
// If the type list contains only one type, you can write that type
// directly without Types<...>:
// TYPED_TEST_CASE(FooTest, int);
// Then, use TYPED_TEST() instead of TEST_F() to define as many typed
// tests for this test case as you want.

// Inside a test, refer to TypeParam to get the type parameter.
// Since we are inside a derived class template, C++ requires use to
// visit the members of FooTest via 'this'.
TypeParam n = this->value_;
// To visit static members of the fixture, add the TestFixture::
// prefix.
n += TestFixture::shared_;
// To refer to typedefs in the fixture, add the "typename
// TestFixture::" prefix.

values.push_back(n);
...
}
TYPED_TEST(FooTest, HasPropertyA) { ... }
#endif // 0
// Type-parameterized tests are abstract test patterns parameterized
// by a type. Compared with typed tests, type-parameterized tests
// allow you to define the test pattern without knowing what the type
// parameters are. The defined pattern can be instantiated with
// different types any number of times, in any number of translation
// units.
//
// If you are designing an interface or concept, you can define a
// suite of type-parameterized tests to verify properties that any
// valid implementation of the interface/concept should have. Then,
// each implementation can easily instantiate the test suite to verify
// that it conforms to the requirements, without having to write
// similar tests repeatedly. Here's an example:
#if 0
// First, define a fixture class template. It should be parameterized
// by a type. Remember to derive it from testing::Test.
template <typename T>
class FooTest : public testing::Test {
...
};
// Next, declare that you will define a type-parameterized test case
// (the _P suffix is for "parameterized" or "pattern", whichever you
// prefer):
TYPED_TEST_CASE_P(FooTest);
// Then, use TYPED_TEST_P() to define as many type-parameterized tests
// for this type-parameterized test case as you want.
TYPED_TEST_P(FooTest, DoesBlah) {
// Inside a test, refer to TypeParam to get the type parameter.
TypeParam n = 0;
...
}

// you can instantiate them. The first argument of the macro is the
// test case name; the rest are the names of the tests in this test
// case.
REGISTER_TYPED_TEST_CASE_P(FooTest,
DoesBlah, HasPropertyA);
// Finally, you are free to instantiate the pattern with the types you
// want. If you put the above code in a header file, you can #include
// it in multiple C++ source files and instantiate it multiple times.
//
// To distinguish different instances of the pattern, the first
// argument to the INSTANTIATE_* macro is a prefix that will be added

// If you expect your predicate to be reused and want to support informative

//
// testing::AssertionResult IsEven(int n) {

// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
//
// Value of: IsEven(Fib(6))
// Actual: true (8 is even)
// Expected: false
//
// NB: Predicates that support negative Boolean assertions have reduced
// performance in positive ones so be careful not to use them in tests
// that have lots (tens of thousands) of positive Boolean assertions.
//
// To use this class with EXPECT_PRED_FORMAT assertions such as:
//
// // Verifies that Foo() returns an even number.
// EXPECT_PRED_FORMAT1(IsEven, Foo());
//
// you need to define:
//
// testing::AssertionResult IsEven(const char* expr, int n) {
// if ((n % 2) == 0)
// return testing::AssertionSuccess();
// else
// return testing::AssertionFailure()
// << "Expected: " << expr << " is even\n Actual: it's " << n;
// }
//
// If Foo() returns 5, you will see the following message:
//
// Expected: Foo() is even
// Actual: it's 5

// When they are not, Google Test prints both the tested expressions and

// values can be compared by the respective operator.
//
// Note:
//
// 1. It is possible to make a user-defined type work with
// {ASSERT|EXPECT}_??(), but that requires overloading the
// comparison operators and is thus discouraged by the Google C++
// Usage Guide. Therefore, you are advised to use the
// {ASSERT|EXPECT}_TRUE() macro to assert that two objects are
// equal.
//
// 2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
// pointers (in particular, C strings). Therefore, if you use it
// with two C strings, you are testing how their locations in memory
// are related, not how their content is related. To compare two C
// strings by content, use {ASSERT|EXPECT}_STR*().
//
// 3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
// {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
// what the actual value is when it fails, and similarly for the
// other comparisons.
//
// 4. Do not depend on the order in which {ASSERT|EXPECT}_??()
// evaluate their arguments, which is undefined.
//
// 5. These macros evaluate their arguments exactly once.

//
// EXPECT_NE(5, Foo());
// EXPECT_EQ(NULL, a_pointer);
// ASSERT_LT(i, array_size);

// Compile-time assertion for type equality.
// StaticAssertTypeEq<type1, type2>() compiles iff type1 and type2 are
// the same type. The value it returns is not interesting.
//
// Instead of making StaticAssertTypeEq a class template, we make it a
// function template that invokes a helper class template. This
// prevents a user from misusing StaticAssertTypeEq<T1, T2> by
// defining objects of that type.
//
// CAVEAT:
//
// When used inside a method of a class template,
// StaticAssertTypeEq<T1, T2>() is effective ONLY IF the method is
// instantiated. For example, given:
//
// template <typename T> class Foo {
// public:
// void Bar() { testing::StaticAssertTypeEq<int, T>(); }
// };
//
// the code:
//
// void Test1() { Foo<bool> foo; }
//
// will NOT generate a compiler error, as Foo<bool>::Bar() is never
// actually instantiated. Instead, you need:
//
// void Test2() { Foo<bool> foo; foo.Bar(); }
//
// to cause a compiler error.

// The 64-bit factor is variable and passed in, the 128-bit factor comes
// from a lookup table. We know that the 64-bit factor only has 55
// significant bits (i.e., the 9 topmost bits are zeros). The 128-bit
// factor only has 124 significant bits (i.e., the 4 topmost bits are
// zeros).
// Shift:
// In principle, the multiplication result requires 55 + 124 = 179 bits to
// represent. However, we then shift this value to the right by j, which is
// at least j >= 115, so the result is guaranteed to fit into 179 - 115 = 64
// bits. This means that we only need the topmost 64 significant bits of
// the 64x128-bit multiplication.
//
// There are several ways to do this:
// 1. Best case: the compiler exposes a 128-bit type.
// We perform two 64x64-bit multiplications, add the higher 64 bits of the
// lower result to the higher result, and shift by j - 64 bits.
//
// We explicitly cast from 64-bit to 128-bit, so the compiler can tell
// that these are only 64-bit inputs, and can map these to the best
// possible sequence of assembly instructions.
// x64 machines happen to have matching assembly instructions for
// 64x64-bit multiplications and 128-bit shifts.
//
// 2. Second best case: the compiler exposes intrinsics for the x64 assembly
// instructions mentioned in 1.
//
// 3. We only have 64x64 bit instructions that return the lower 64 bits of
// the result, i.e., we have to use plain C.
// Our inputs are less than the full width, so we have three options:
// a. Ignore this fact and just implement the intrinsics manually.
// b. Split both into 31-bit pieces, which guarantees no internal overflow,
// but requires extra work upfront (unless we change the lookup table).
// c. Split only the first factor into 31-bit pieces, which also guarantees
// no internal overflow, but requires extra work since the intermediate
// results are not perfectly aligned.

## Things to know
My CPU is a Amd Ryzen 9 7950x, so results may vary *a lot* on other CPUs.
My Rust binary is still pretty small compared to normal Rust binaries, check the [Cargo.toml](./rust/Cargo.toml#L11) file for more info.
The C and Rust binaries are dynamically linked, and the Zig binary is statically linked.
## C (clang v15.0.7)
Build
```bash
clang -Ofast -lm main.c -o sieve
```
Result
```bash
time ./sieve 100000000
# 0.33s, 96MB MAX RAM, 16k binary size
```
## Zig (v0.10.1)
Build
```bash
zig build -Drelease-fast
```
Result
```bash
time ./zig-out/bin/zig 100000000
# 0.44s, 143MB MAX RAM, 25k binary size
```
## Rust (v1.68.2)
Build
```bash
cargo build --release
```
Result
```bash
time ./target/release/rust 100000000
# 0.47s, 96MB MAX RAM, 293k binary size
```

[](https://github.com/dying-will-bullet/slugify/actions/workflows/ci.yaml)
Small utility library for generating ASCII string from a Unicode string. It could handle most major languages and emojis.
## Examples
```zig
const std = @import("std");
const slugify = @import("slugify").slugify;
const slugifyAlloc = @import("slugify").slugifyAlloc;
pub fn main() !void {
const allocator = std.heap.page_allocator;
const res = try slugifyAlloc(allocator, " Déjà Vu! ", .{});
defer allocator.free(res);
std.debug.print("{s}\n", .{res}); // deja-vu
// Or use a buffer
var buf: [1024]u8 = undefined;
const res2 = try slugify(&buf, "𝒔𝒍𝒖𝒈𝒊𝒇𝒚 𝒂 𝒔𝒕𝒓𝒊𝒏𝒈", .{});
std.debug.print("{s}\n", .{res2}); // slugify-a-string
}
```
## Installation
You can install it using a package manager or manually as shown below.
Add `slugify` as dependency in `build.zig.zon`:
```
.{
.name = "my-project",
.version = "0.1.0",
.dependencies = .{
.slugify = .{
.url = "https://github.com/dying-will-bullet/slugify/archive/refs/tags/v0.1.0.tar.gz",

},
},
}
```
Add `slugify` as module in `build.zig`:
```diff

```
## API
### `Options`
Used to control the conversion behavior, with the following default values.
```zig
const Dict = std.AutoHashMap(u21, []const u8);
const Options = struct {
sep: []const u8 = "-",
dict: ?Dict = null,
};
```
`dict`: Add your own custom replacements. The replacements are run on the original string **before** any other transformations.
```zig
var dict = Dict.init(allocator);
defer dict.deinit();
// 128049 is the code point of 🐱
try dict.put(128049, "neko");
const res = try slugifyAlloc(allocator, "I love 🐱.", .{ .dict = dict }); // i-love-neko
defer allocator.free(res);
```
### `slugifyAlloc(allocator: Allocator, s: []const u8, options: Options) ![]const u8`
Return the converted string. The caller is should free the memory.
### `slugify(dest: []u8, s: []const u8, options: Options) ![]const u8`
Use buffer instead of allocator. Return a slice of the buffer.
## slugify implementations in different languages
It is important to note that there is no universal standard for converting a Unicode character to an ASCII string.
The same Han character may have different transliterations in different languages.
For example, in Japanese, "世界" is transliterated as "sekai," while in Chinese, it is transliterated as "shijie".
This complexity also applies to emojis. For instance, the ♥ emoji can represent "love" or "heart" depending on the context.
Different implementations may use different mapping table, and I cannot guarantee that their results will be the same.
Here are slugify implementations in other languages:
- Java: [slugify/slugify](https://github.com/slugify/slugify)
- Rust: [Stebalien/slug-rs](https://github.com/Stebalien/slug-rs)
- Python: [un33k/python-slugify](https://github.com/un33k/python-slugify)
- JavaScript: [simov/slugify](https://github.com/simov/slugify)
- JavaScript: [sindresorhus/slugify](https://github.com/sindresorhus/slugify)

Are you tired of having to write your CUDA kernel code in C++?
This project aims to make it possible to compile CUDA kernels written in any language supported by LLVM without much hassle.
Specifically, this is basically a transpiler from LLVM-IR to NVVM-IR.
Importantly, languages like plain C, Rust and Zig are all supported.
Expecially CUDA in Rust is not yet very good and [Rust-CUDA](https://github.com/Rust-GPU/Rust-CUDA) has been stale since July 2022.
Maybe we can fix that by using a different approach to the problem of CUDA codegen.
**This is not a CUDA runtime API wrapper! You cannot run the kernels with this project alone!**
If you're just looking for a simple way to write CUDA in Rust though, you're in luck.
[cust](https://crates.io/crates/cust) is a really good wrapper around the CUDA API.
## How it works
In order to compile a kernel in any language with an LLVM frontend, we
* Invoke the standard compiler for the language and tell it to output LLVM bitcode for the nvptx64-nvidia-cuda target
* Pass the generated bitcode to the code transformer (cutransform)
* The transformer will parse the bitcode and add required attributes and functions and structs
* It will output this modified version of the bitcode
* Finally the bitcode can simply be passed through the llvm-bitcode compiler, llc to generate the PTX assembly
* (Optional) Additionally can now choose to assemble the PTX to a SASS (cubin) program for your specific graphics card using Nvidia's proprietary ptxas assembler
## Setup
You should already have
* clang
* llvm
* cuda
Then compile the cutransform binary:
cd cutransform
cargo build --release
If the build fails with an error message from the `llvm-sys` crate, you likely have a build of LLVM without the static libraries.
This is the default for newer LLVM binary distributions.
To build with a dynamically linked LLVM, run:
cargo build --release --features dynamic-llvm
instead.
## Rust example usage
First, make sure you have the nvptx Rust target installed:
rustup target add nvptx64-nvidia-cuda
Here is an example Rust kernel:
```rust
#![no_std]
extern "C" {
fn threadIdxX() -> u32;
}
#[no_mangle]
pub extern "C" fn kernel(arr: *mut u32) {
unsafe {
let idx = threadIdxX() as usize;
*arr.add(idx) = 123;
}
}
```
**Please note that all kernel functions should have a name starting with the word "kernel". Otherwise they won't be exported.**
To compile the Rust kernel to LLVM bitcode, run:
rustc -O -C opt-level=3 -o kernel.bc --emit llvm-bc --target nvptx64-nvidia-cuda -C target-cpu=sm_86 -C target-feature=+ptx75 --crate-type lib kernel.rs
You can change `sm_86` flag to the minimum supported compute capability of your kernel (8.6 is the newest supported in clang and it's mostly for 30-series cards and onwards).
Refer to [this Wikipedia page](https://en.wikipedia.org/wiki/CUDA#GPUs_supported) for a list of cards and their supported compute capabilities.
Now, run cutransform on the llvm bitcode
cutransform/target/release/cutransform kernel.bc
Finally, compile the new bitcode to PTX:
llc -O3 -mcpu=sm_86 -mattr=+ptx75 kernel.bc
Now you can also choose to assemble the PTX for your card:
ptxas --allow-expensive-optimizations true -o kernel.cubin --gpu-name sm_89 kernel.s
Where you can again change `sm_89` to the compute capability of your card.
Compute capability 8.9 is for 40-series cards.
For a complete and integrated example, see the `rust-example` crate included in this repo.
## C example usage
Here is an example C kernel:
```c
extern int threadIdxX(void);
void kernel(int *arr) {
arr[threadIdxX()] = 123;
}
```
**Please note that all kernel functions should have a name starting with the word "kernel". Otherwise they won't be exported.**
To compile the C kernel to LLVM bitcode, run:
clang -cc1 -O3 -triple=nvptx64-nvidia-cuda -target-cpu sm_86 -target-feature +ptx75 -emit-llvm-bc -o kernel.bc kernel.c
Now, run cutransform on the llvm bitcode
cutransform/target/release/cutransform kernel.bc
Finally, compile the new bitcode to PTX:
llc -O3 -mcpu=sm_86 -mattr=+ptx75 kernel.bc
Now you can also choose to assemble the PTX for your card:
ptxas --allow-expensive-optimizations true -o kernel.cubin --gpu-name sm_89 kernel.s
Where you can again change `sm_89` to the compute capability of your card.
Compute capability 8.9 is for 40-series cards.
For a complete and integrated example, see the `c-example` folder included in this repo.
## Zig example usage
Here is an example Zig kernel:
```zig
extern fn threadIdxX() i32;
export fn kernel(arr: [*]u32) callconv(.C) void {
arr[@intCast(usize, threadIdxX())] = 123;
}
// Override the default entrypoint
pub fn _start() callconv(.Naked) void {}
```
**Please note that all kernel functions should have a name starting with the word "kernel". Otherwise they won't be exported.**
To compile the Zig kernel to LLVM bitcode, run:
zig build-obj -O ReleaseSmall -target nvptx64-cuda -mcpu sm_86+ptx75 -fno-emit-asm -femit-llvm-bc=kernel.bc kernel.zig
Now, run cutransform on the llvm bitcode
cutransform/target/release/cutransform kernel.bc
Finally, compile the new bitcode to PTX:
llc -O3 -mcpu=sm_86 -mattr=+ptx75 kernel.bc
Now you can also choose to assemble the PTX for your card:
ptxas --allow-expensive-optimizations true -o kernel.cubin --gpu-name sm_89 kernel.s
Where you can again change `sm_89` to the compute capability of your card.
Compute capability 8.9 is for 40-series cards.
For a complete and integrated example, see the `zig-example` folder included in this repo.

Scafetch is a command-line tool to display information about your remote Git repositories in an aesthetic and visually pleasing way.
It currently supports fetching repository information from Github, Gitlab and Codeberg (Gitea).
# Installation
## Releases
You can get the latest stable [release](https://github.com/iddev5/scafetch/releases) from Github.
## Arch Linux (AUR)
Install the community maintained [scafetch](https://aur.archlinux.org/packages/scafetch) package.
# Usage
You only need Zig master to compile.
Use zig to build:
```
zig build -Doptimize=ReleaseSafe
```
(You can optionally install it in a system or user wide directory for easier access, use the ``-p <prefix>`` flag for convenience)
Then, run the application:
```
./zig-out/bin/scafetch ziglang/zig
```
where ``ziglang/zig`` is taken as an example repository address, and the host defaults to Github
It is also possible to explicitly state the host service name using ``-o <hostname>`` flag. See ``--help`` for more information.
Scafetch can additionally infer the host service from hints present in the given URL:
Host name | 1 | 2 | 3
----------|------------------------|------------------------------|---------------------------------
Github | ``gh/<author>/<repo>`` | ``github/<author>/<repo>`` | ``github.com/<author>/<repo>``
Gitlab | ``gl/<author>/<repo>`` | ``gitlab/<author>/<repo>`` | ``gitlab.com/<author>/<repo>``
Codeberg | ``cb/<author>/<repo>`` | ``codeberg/<author>/<repo>`` | ``codeberg.org/<author>/<repo>``
# Todo
- More CLI flags, like opt out of coloring, what info to display etc.
- Authentication support
- Show an ASCII art of the primary language(?) of the repository
