    log.depth_mark(CLUTCHLOG_DEFAULT_DEPTH_MARK); // Defaults to ">".

    By default, clutchlog removes 5 levels of the calls stack, so that your main entrypoint corresponds to a depth of zero. You can change this behaviour by defining the CLUTCHLOG_STRIP_CALLS macro.

    Note that allowing a log level does not mean that it will actually output something. If the configured log level at runtime is lower than the log level of the message, it will still not be printed.

    This behavior intend to remove as many conditional statements as possible when not debugging, without having to use preprocessor guards around calls to clutchlog, thus saving run time at no readability cost.

    Low-level API

    All configuration setters have a getters counterpart, with the same name but taking no parameter, for example:

    (De)clutch any function call

    The CLUTHFUNC macro allows to wrap any function within the current logger.

    For instance, this can be useful if you want to (de)clutch calls to asserts. To do that, just declare your own macro:

    #define ASSERT(...) { CLUTCHFUNC(error, assert, __VA_ARGS__) }

    Thus, any call like ASSERT(x > 3); will be declutchable with the same configuration than a call to CLUTCHLOG.

    (De)clutch any code section

    The CLUTCHCODE macro allows to wrap any code within the current logger.

    );

    System-dependent stack depth

    -

    Because the call stack depth and program name access are system-dependent, the features relying on the depth of the call stack and the display of the program name are only available for operating systems having the following headers: execinfo.h, stdlib.h and libgen.h (so far, tested with Linux).

    Clutchlog sets the CLUTCHLOG_HAVE_UNIX_SYSINFO to 1 if the headers are available, and to 0 if they are not. You can make portable code using something like:

    #if CLUTCHLOG_HAVE_UNIX_SYSINFO == 1
    log.depth( x );
    #endif
    +

    System-dependent horizontal fill

    +

    Because access to the current terminal width is system-dependent, the {hfill} format tag feature is only available for operating systems having the following headers: sys/ioctl.h, stdio.h and unistd.h (so far, tested with Linux).

    +

    Clutchlog sets the CLUTCHLOG_HAVE_UNIX_SYSIOCTL to 1 if the headers are available, and to 0 if they are not. You can make portable code using something like:

    #if CLUTCHLOG_HAVE_UNIX_SYSIOCTL == 1
    +
    log.hfill_mark( '_' );
    +
    #endif

    Dependencies

    Some colors/styles may not be supported by some exotic terminal emulators.

    Clutchlog needs C++-17 with the filesystem feature. You may need to indicate -std=c++17 -lstdc++fs to some compilers.

    Build and tests

    To use clutchlog, just include its header in your code and either ensure that the NDEBUG preprocessor variable is not set, either define the WITH_CLUTCHLOG preprocessor variable.

    If you're using CMake (or another modern build system), it will unset NDEBUG —and thus enable clutchlog— only for the "Debug" build type, which is usually what you want if you use clutchlog, anyway.
