Personally I don't think this is required, but I don't pretend to represent the tinycc maintainers' opinion. If it is added, however, then the following should probably be taken into account:
- This mostly works, but it won't work on all terminals, for instance the original DEC VT100 has bold but doesn't have colors. - It's probably better to support disabling it by means other than piping stderr into "cat" (so that stdout is not a tty). I.e. using an option, probably with value always/never/auto. Preferably it should also respect NO_COLOR by default. see https://no-color.org/ . - This won't work on Windows before 10, e.g. Windows xp/7/8. - On Windows 10+ this only works if the console/termimal has VT enabled - which is disabled by default, or if it runs in a terminal which supports VT (like mintty in MSYS2 or cygwin). To test if VT is enabled (untested, off the top of my head): DWORD mode; int has_vt; has_vt = GetConsoleMode(GetStdHandle(STD_ERROR_HANDLE), &mode) && (mode & ENABLE_VIRTUAL_TERMINAL_PROCESSING); Note that ENABLE_VIRTUAL_TERMINAL_PROCESSING is new-ish and not defined in the tcc windows headers, so the code above would fail if compiled in tcc. You can define it as 4 if it's not defined. If you go this path, it should be used when compiling on windows (not when the target is windows). - avih On Sunday, May 12, 2024 at 02:36:25 AM GMT+3, Nicolas Sauzede <nicolas.sauz...@gmail.com> wrote: Hi, I created a very simple mob branch to color warnings/errors output, just like GCC and Clang. $ git fetch origin refs/mob/mob_nsauzede/colored_warning_error:colored_warning_error $ git checkout colored_warning_error I tested it successfully on Linux (Arch) and Windows (MSYS2, 64 bits GCC bootstrap)It uses `isatty(2)` (unistd.h) to detect if the output should be colored (default) or not (eg: piped to a file) to behave like GCC and Clang.
