  133. // Environment-describing macros
  134. // -----------------------------
  135. //
  136. // Google Test can be used in many different environments. Macros in
  137. // this section tell Google Test what kind of environment it is being
  138. // used in, such that Google Test can provide environment-specific
  139. // features and implementations.
  140. //
  141. // Google Test tries to automatically detect the properties of its
  142. // environment, so users usually don't need to worry about these
  143. // macros. However, the automatic detection is not perfect.
  144. // Sometimes it's necessary for a user to define some of the following
  145. // macros in the build script to override Google Test's decisions.
  146. //
  147. // If the user doesn't define a macro in the list, Google Test will
  148. // provide a default definition. After this header is #included, all
  149. // macros in this list will be defined to either 1 or 0.
  150. //
  151. // Notes to maintainers:
  152. // - Each macro here is a user-tweakable knob; do not grow the list
  153. // lightly.
  154. // - Use #if to key off these macros. Don't use #ifdef or "#if
  155. // defined(...)", which will not work as these macros are ALWAYS
  156. // defined.
  157. //
  158. // GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
  159. // is/isn't available.
  160. // GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
  161. // are enabled.
  162. // GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
  163. // is/isn't available
  164. // GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
  165. // is/isn't available
  166. // GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
  167. // expressions are/aren't available.
  168. // GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
  169. // is/isn't available.
  170. // GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
  171. // enabled.
  172. // GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
  173. // std::wstring does/doesn't work (Google Test can
  174. // be used where std::wstring is unavailable).
  175. // GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
  176. // compiler supports Microsoft's "Structured
  177. // Exception Handling".
  178. // GTEST_HAS_STREAM_REDIRECTION
  179. // - Define it to 1/0 to indicate whether the
  180. // platform supports I/O stream redirection using
  181. // dup() and dup2().
  182. // GTEST_LINKED_AS_SHARED_LIBRARY
  183. // - Define to 1 when compiling tests that use
  184. // Google Test as a shared library (known as
  185. // DLL on Windows).
  186. // GTEST_CREATE_SHARED_LIBRARY
  187. // - Define to 1 when compiling Google Test itself
  188. // as a shared library.
  189. // GTEST_DEFAULT_DEATH_TEST_STYLE
  190. // - The default value of --gtest_death_test_style.
  191. // The legacy default has been "fast" in the open
  192. // source version since 2008. The recommended value
  193. // is "threadsafe", and can be set in
  194. // custom/gtest-port.h.
  195. // Platform-indicating macros
  196. // --------------------------
  197. //
  198. // Macros indicating the platform on which Google Test is being used
  199. // (a macro is defined to 1 if compiled on the given platform;
  200. // otherwise UNDEFINED -- it's never defined to 0.). Google Test
  201. // defines these macros automatically. Code outside Google Test MUST
  202. // NOT define them.
  203. //
  204. // GTEST_OS_AIX - IBM AIX
  205. // GTEST_OS_CYGWIN - Cygwin
  206. // GTEST_OS_FREEBSD - FreeBSD

  208. // GTEST_OS_HPUX - HP-UX
  209. // GTEST_OS_LINUX - Linux
  210. // GTEST_OS_LINUX_ANDROID - Google Android
  211. // GTEST_OS_MAC - Mac OS X
  212. // GTEST_OS_IOS - iOS

  223. // GTEST_OS_WINDOWS_PHONE - Windows Phone
  224. // GTEST_OS_WINDOWS_RT - Windows Store App/WinRT
  225. // GTEST_OS_ZOS - z/OS
  226. //
  227. // Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
  228. // most stable support. Since core members of the Google Test project
  229. // don't have access to other platforms, support for them may be less
  230. // stable. If you notice any problems on your platform, please notify
  231. // googletestframework@googlegroups.com (patches for fixing them are

  233. //
  234. // It is possible that none of the GTEST_OS_* macros are defined.
  235. // Feature-indicating macros
  236. // -------------------------
  237. //
  238. // Macros indicating which Google Test features are available (a macro
  239. // is defined to 1 if the corresponding feature is supported;
  240. // otherwise UNDEFINED -- it's never defined to 0.). Google Test
  241. // defines these macros automatically. Code outside Google Test MUST
  242. // NOT define them.
  243. //
  244. // These macros are public so that portable tests can be written.
  245. // Such tests typically surround code using a feature with an #if
  246. // which controls that code. For example:
  247. //
  248. // #if GTEST_HAS_DEATH_TEST
  249. // EXPECT_DEATH(DoSomethingDeadly());
  250. // #endif
  251. //
  252. // GTEST_HAS_DEATH_TEST - death tests
  253. // GTEST_HAS_TYPED_TEST - typed tests
  254. // GTEST_HAS_TYPED_TEST_P - type-parameterized tests
  255. // GTEST_IS_THREADSAFE - Google Test is thread-safe.
  256. // GOOGLETEST_CM0007 DO NOT DELETE
  257. // GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
  258. // GTEST_HAS_POSIX_RE (see above) which users can
  259. // define themselves.
  260. // GTEST_USES_SIMPLE_RE - our own simple regex is used;
  261. // the above RE\b(s) are mutually exclusive.
  262. // Misc public macros
  263. // ------------------
  264. //
  265. // GTEST_FLAG(flag_name) - references the variable corresponding to
  266. // the given Google Test flag.
  267. // Internal utilities
  268. // ------------------
  269. //
  270. // The following macros and utilities are for Google Test's INTERNAL
  271. // use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
  272. //
  273. // Macros for basic C++ coding:
  274. // GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
  275. // GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
  276. // variable don't have to be used.
  277. // GTEST_DISALLOW_ASSIGN_ - disables operator=.
  278. // GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
  279. // GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
  280. // GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
  281. // suppressed (constant conditional).
  282. // GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
  283. // is suppressed.
  284. //
  285. // Synchronization:
  286. // Mutex, MutexLock, ThreadLocal, GetThreadCount()
  287. // - synchronization primitives.
  288. //
  289. // Template meta programming:
  290. // IteratorTraits - partial implementation of std::iterator_traits, which
  291. // is not available in libCstd when compiled with Sun C++.
  292. //
  293. //
  294. // Regular expressions:
  295. // RE - a simple regular expression class using the POSIX
  296. // Extended Regular Expression syntax on UNIX-like platforms
  297. // GOOGLETEST_CM0008 DO NOT DELETE
  298. // or a reduced regular exception syntax on other
  299. // platforms, including Windows.
  300. // Logging:
  301. // GTEST_LOG_() - logs messages at the specified severity level.
  302. // LogToStderr() - directs all log messages to stderr.
  303. // FlushInfoLog() - flushes informational log messages.
  304. //
  305. // Stdout and stderr capturing:
  306. // CaptureStdout() - starts capturing stdout.
  307. // GetCapturedStdout() - stops capturing stdout and returns the captured
  308. // string.
  309. // CaptureStderr() - starts capturing stderr.
  310. // GetCapturedStderr() - stops capturing stderr and returns the captured
  311. // string.
  312. //
  313. // Integer types:
  314. // TypeWithSize - maps an integer to a int type.
  315. // Int32, UInt32, Int64, UInt64, TimeInMillis
  316. // - integers of known sizes.
  317. // BiggestInt - the biggest signed integer type.
  318. //
  319. // Command-line utilities:
  320. // GTEST_DECLARE_*() - declares a flag.
  321. // GTEST_DEFINE_*() - defines a flag.
  322. // GetInjectableArgvs() - returns the command line as a vector of strings.
  323. //
  324. // Environment variable utilities:
  325. // GetEnv() - gets the value of an environment variable.
  326. // BoolFromGTestEnv() - parses a bool environment variable.
  327. // Int32FromGTestEnv() - parses an Int32 environment variable.
