46 // Environment-describing macros
47 // -----------------------------
48 //
49 // Google Test can be used in many different environments. Macros in
50 // this section tell Google Test what kind of environment it is being
51 // used in, such that Google Test can provide environment-specific
52 // features and implementations.
53 //
54 // Google Test tries to automatically detect the properties of its
55 // environment, so users usually don't need to worry about these
56 // macros. However, the automatic detection is not perfect.
57 // Sometimes it's necessary for a user to define some of the following
58 // macros in the build script to override Google Test's decisions.
59 //
60 // If the user doesn't define a macro in the list, Google Test will
61 // provide a default definition. After this header is #included, all
62 // macros in this list will be defined to either 1 or 0.
63 //
64 // Notes to maintainers:
65 // - Each macro here is a user-tweakable knob; do not grow the list
66 // lightly.
67 // - Use #if to key off these macros. Don't use #ifdef or "#if
68 // defined(...)", which will not work as these macros are ALWAYS
69 // defined.
70 //
71 // GTEST_HAS_CLONE - Define it to 1/0 to indicate that clone(2)
72 // is/isn't available.
73 // GTEST_HAS_EXCEPTIONS - Define it to 1/0 to indicate that exceptions
74 // are enabled.
75 // GTEST_HAS_GLOBAL_STRING - Define it to 1/0 to indicate that ::string
76 // is/isn't available
77 // GTEST_HAS_GLOBAL_WSTRING - Define it to 1/0 to indicate that ::wstring
78 // is/isn't available
79 // GTEST_HAS_POSIX_RE - Define it to 1/0 to indicate that POSIX regular
80 // expressions are/aren't available.
81 // GTEST_HAS_PTHREAD - Define it to 1/0 to indicate that <pthread.h>
82 // is/isn't available.
83 // GTEST_HAS_RTTI - Define it to 1/0 to indicate that RTTI is/isn't
84 // enabled.
85 // GTEST_HAS_STD_WSTRING - Define it to 1/0 to indicate that
86 // std::wstring does/doesn't work (Google Test can
87 // be used where std::wstring is unavailable).
88 // GTEST_HAS_SEH - Define it to 1/0 to indicate whether the
89 // compiler supports Microsoft's "Structured
90 // Exception Handling".
91 // GTEST_HAS_STREAM_REDIRECTION
92 // - Define it to 1/0 to indicate whether the
93 // platform supports I/O stream redirection using
94 // dup() and dup2().
95 // GTEST_LINKED_AS_SHARED_LIBRARY
96 // - Define to 1 when compiling tests that use
97 // Google Test as a shared library (known as
98 // DLL on Windows).
99 // GTEST_CREATE_SHARED_LIBRARY
100 // - Define to 1 when compiling Google Test itself
101 // as a shared library.
102 // GTEST_DEFAULT_DEATH_TEST_STYLE
103 // - The default value of --gtest_death_test_style.
104 // The legacy default has been "fast" in the open
105 // source version since 2008. The recommended value
106 // is "threadsafe", and can be set in
107 // custom/gtest-port.h.
108 
109 // Platform-indicating macros
110 // --------------------------
111 //
112 // Macros indicating the platform on which Google Test is being used
113 // (a macro is defined to 1 if compiled on the given platform;
114 // otherwise UNDEFINED -- it's never defined to 0.). Google Test
115 // defines these macros automatically. Code outside Google Test MUST
116 // NOT define them.
117 //
118 // GTEST_OS_AIX - IBM AIX
119 // GTEST_OS_CYGWIN - Cygwin
120 // GTEST_OS_DRAGONFLY - DragonFlyBSD
121 // GTEST_OS_FREEBSD - FreeBSD
122 // GTEST_OS_FUCHSIA - Fuchsia
123 // GTEST_OS_GNU_KFREEBSD - GNU/kFreeBSD
124 // GTEST_OS_HPUX - HP-UX
125 // GTEST_OS_LINUX - Linux
126 // GTEST_OS_LINUX_ANDROID - Google Android
127 // GTEST_OS_MAC - Mac OS X
128 // GTEST_OS_IOS - iOS
129 // GTEST_OS_NACL - Google Native Client (NaCl)
130 // GTEST_OS_NETBSD - NetBSD

139 // GTEST_OS_WINDOWS_PHONE - Windows Phone
140 // GTEST_OS_WINDOWS_RT - Windows Store App/WinRT
141 // GTEST_OS_ZOS - z/OS
142 //
143 // Among the platforms, Cygwin, Linux, Max OS X, and Windows have the
144 // most stable support. Since core members of the Google Test project
145 // don't have access to other platforms, support for them may be less
146 // stable. If you notice any problems on your platform, please notify
147 // googletestframework@googlegroups.com (patches for fixing them are
148 // even more welcome!).
149 //
150 // It is possible that none of the GTEST_OS_* macros are defined.
151 
152 // Feature-indicating macros
153 // -------------------------
154 //
155 // Macros indicating which Google Test features are available (a macro
156 // is defined to 1 if the corresponding feature is supported;
157 // otherwise UNDEFINED -- it's never defined to 0.). Google Test
158 // defines these macros automatically. Code outside Google Test MUST
159 // NOT define them.
160 //
161 // These macros are public so that portable tests can be written.
162 // Such tests typically surround code using a feature with an #if
163 // which controls that code. For example:
164 //
165 // #if GTEST_HAS_DEATH_TEST
166 // EXPECT_DEATH(DoSomethingDeadly());
167 // #endif
168 //
169 // GTEST_HAS_DEATH_TEST - death tests
170 // GTEST_HAS_TYPED_TEST - typed tests
171 // GTEST_HAS_TYPED_TEST_P - type-parameterized tests
172 // GTEST_IS_THREADSAFE - Google Test is thread-safe.
173 // GOOGLETEST_CM0007 DO NOT DELETE
174 // GTEST_USES_POSIX_RE - enhanced POSIX regex is used. Do not confuse with
175 // GTEST_HAS_POSIX_RE (see above) which users can
176 // define themselves.
177 // GTEST_USES_SIMPLE_RE - our own simple regex is used;
178 // the above RE\b(s) are mutually exclusive.
179 
180 // Misc public macros
181 // ------------------
182 //
183 // GTEST_FLAG(flag_name) - references the variable corresponding to
184 // the given Google Test flag.
185 
186 // Internal utilities
187 // ------------------
188 //
189 // The following macros and utilities are for Google Test's INTERNAL
190 // use only. Code outside Google Test MUST NOT USE THEM DIRECTLY.
191 //
192 // Macros for basic C++ coding:
193 // GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
194 // GTEST_ATTRIBUTE_UNUSED_ - declares that a class' instances or a
195 // variable don't have to be used.
196 // GTEST_DISALLOW_ASSIGN_ - disables operator=.
197 // GTEST_DISALLOW_COPY_AND_ASSIGN_ - disables copy ctor and operator=.
198 // GTEST_MUST_USE_RESULT_ - declares that a function's result must be used.
199 // GTEST_INTENTIONAL_CONST_COND_PUSH_ - start code section where MSVC C4127 is
200 // suppressed (constant conditional).
201 // GTEST_INTENTIONAL_CONST_COND_POP_ - finish code section where MSVC C4127
202 // is suppressed.
203 //
204 // Synchronization:
205 // Mutex, MutexLock, ThreadLocal, GetThreadCount()
206 // - synchronization primitives.
207 //
208 // Template meta programming:
209 // IteratorTraits - partial implementation of std::iterator_traits, which
210 // is not available in libCstd when compiled with Sun C++.
211 //
212 //
213 // Regular expressions:
214 // RE - a simple regular expression class using the POSIX
215 // Extended Regular Expression syntax on UNIX-like platforms
216 // GOOGLETEST_CM0008 DO NOT DELETE
217 // or a reduced regular exception syntax on other
218 // platforms, including Windows.
219 // Logging:
220 // GTEST_LOG_() - logs messages at the specified severity level.
221 // LogToStderr() - directs all log messages to stderr.
222 // FlushInfoLog() - flushes informational log messages.
223 //
224 // Stdout and stderr capturing:
225 // CaptureStdout() - starts capturing stdout.
226 // GetCapturedStdout() - stops capturing stdout and returns the captured
227 // string.
228 // CaptureStderr() - starts capturing stderr.
229 // GetCapturedStderr() - stops capturing stderr and returns the captured
230 // string.
231 //
232 // Integer types:
233 // TypeWithSize - maps an integer to a int type.
234 // Int32, UInt32, Int64, UInt64, TimeInMillis
235 // - integers of known sizes.
236 // BiggestInt - the biggest signed integer type.
237 //
238 // Command-line utilities:
239 // GTEST_DECLARE_*() - declares a flag.
240 // GTEST_DEFINE_*() - defines a flag.
241 // GetInjectableArgvs() - returns the command line as a vector of strings.
242 //
243 // Environment variable utilities:
244 // GetEnv() - gets the value of an environment variable.
245 // BoolFromGTestEnv() - parses a bool environment variable.
246 // Int32FromGTestEnv() - parses an Int32 environment variable.
247 // StringFromGTestEnv() - parses a string environment variable.
248 //
249 // Deprecation warnings:
250 // GTEST_INTERNAL_DEPRECATED(message) - attribute marking a function as
251 // deprecated; calling a marked function
252 // should generate a compiler warning
