I know that this is a long time after the original query, but this may still be useful. This can be done in GCC using the stringify operator “#”, but it requires two stages. #define XSTR(x) STR(x) #define STR(x) #x The value of a macro can then be displayed with: #pragma message “The value of … Read more
This question is answered in duplicate by Travis here. There are links to the issue in the tracker and to Eugene’s discussion (in the comments and mailing list). In the famous “Skylla and Charybdis” section of the type checker, our hero decides what shall escape dark anonymity and see the light as a member of … Read more
#pragma comment is a compiler directive which indicates Visual C++ to leave a comment in the generated object file. The comment can then be read by the linker when it processes object files. #pragma comment(lib, libname) tells the linker to add the ‘libname’ library to the list of library dependencies, as if you had added … Read more
Use q followed by a letter (for example ‘x’) to record a macro, then press q to end the macro definition. The pattern surrounded by the starting and ending ‘q’ during this definition just goes into one of the copy/paste registers (in this case, register ‘x’) so you can paste it with the”xp or “xP … Read more
Try #include <string.h> #define __FILENAME__ (strrchr(__FILE__, “https://stackoverflow.com/”) ? strrchr(__FILE__, “https://stackoverflow.com/”) + 1 : __FILE__) For Windows use ‘\\’ instead of “https://stackoverflow.com/”.
You can try the Text Macros for Visual Studio 2012-2019 extension (I am the author). It basically does the same thing as the Notepad++ macros (text editing, no UI automation). The code is open source (GitHub), so feel free to contribute improvements 🙂
Andrey Tarasevich provides the following explanation: On Google Groups On bytes.com [Minor changes to formatting made. Parenthetical annotations added in square brackets []]. The whole idea of using ‘do/while’ version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the … Read more
Simple as: #define GET_MACRO(_1,_2,_3,NAME,…) NAME #define FOO(…) GET_MACRO(__VA_ARGS__, FOO3, FOO2)(__VA_ARGS__) So if you have these macros, they expand as described: FOO(World, !) // expands to FOO2(World, !) FOO(foo,bar,baz) // expands to FOO3(foo,bar,baz) If you want a fourth one: #define GET_MACRO(_1,_2,_3,_4,NAME,…) NAME #define FOO(…) GET_MACRO(__VA_ARGS__, FOO4, FOO3, FOO2)(__VA_ARGS__) FOO(a,b,c,d) // expands to FOO4(a,b,c,d) Naturally, if you … Read more
Like this #if defined(LINUX) || defined(ANDROID)
Let’s see: “https://stackoverflow.com/” / “https://stackoverflow.com/” means the char literal /, divided by the char literal “https://stackoverflow.com/” itself. The result is one, which sounds reasonable for TRUE. And ‘-‘ – ‘-‘ means the char literal ‘-‘, subtracted from itself. This is zero (FALSE). There are two problems with this: first, it’s not readable. Using 1 and … Read more
