| // 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_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_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_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. |
| // GTEST_DEFAULT_DEATH_TEST_STYLE |
| // - The default value of --gtest_death_test_style. |
| // The legacy default has been "fast" in the open |
| // source version since 2008. The recommended value |
| // is "threadsafe", and can be set in |
| // custom/gtest-port.h. |
| |
| // 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_DRAGONFLY - DragonFlyBSD |
| // GTEST_OS_FREEBSD - FreeBSD |
| // GTEST_OS_FUCHSIA - Fuchsia |
| // GTEST_OS_GNU_KFREEBSD - GNU/kFreeBSD |
| // GTEST_OS_HAIKU - Haiku |
| // 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_NETBSD - NetBSD |
| // GTEST_OS_OPENBSD - OpenBSD |
| // GTEST_OS_OS2 - OS/2 |
| // GTEST_OS_QNX - QNX |
| // GTEST_OS_SOLARIS - Sun Solaris |
| // 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, Mac 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 |
| // googletestframework@googlegroups.com (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_DEATH_TEST - death tests |
| // GTEST_HAS_TYPED_TEST - typed tests |
| // GTEST_HAS_TYPED_TEST_P - type-parameterized tests |
| // GTEST_IS_THREADSAFE - Google Test is thread-safe. |
| // GOOGLETEST_CM0007 DO NOT DELETE |
| // 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 RE\b(s) are mutually exclusive. |
| |
| // 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_MOVE_ASSIGN_ - disables move operator=. |
| // GTEST_DISALLOW_MOVE_AND_ASSIGN_ - disables move 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. |
| // GTEST_INTERNAL_HAS_ANY - for enabling UniversalPrinter<std::any> or |

| // UniversalPrinter<absl::optional> |
| // specializations. |
| // GTEST_INTERNAL_HAS_STRING_VIEW - for enabling Matcher<std::string_view> or |
| // Matcher<absl::string_view> |

| // |
| // Synchronization: |
| // Mutex, MutexLock, ThreadLocal, GetThreadCount() |
| // - synchronization primitives. |
| // |
| // Regular expressions: |
| // RE - a simple regular expression class using the POSIX |
| // Extended Regular Expression syntax on UNIX-like platforms |

| // string. |

| // string. |
| // |
| // Integer types: |
| // TypeWithSize - maps an integer to a int type. |
| // TimeInMillis - integers of known sizes. |
| // BiggestInt - the biggest signed integer type. |
| // |
| // Command-line utilities: |
| // GTEST_DECLARE_*() - declares a flag. |
| // GTEST_DEFINE_*() - defines a flag. |
| // GetInjectableArgvs() - returns the command line as a vector of strings. |
| // |
| // Environment variable utilities: |
| // GetEnv() - gets the value of an environment variable. |
| // BoolFromGTestEnv() - parses a bool environment variable. |
| // Int32FromGTestEnv() - parses an int32_t environment variable. |
| // StringFromGTestEnv() - parses a string environment variable. |
| // |
| // Deprecation warnings: |
| // GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as |
| // deprecated; calling a marked function |
| // should generate a compiler warning |
