nl_squeeze_ifdef

Whether to remove blanks after #ifxx and #elxx, or before #elxx and #endif. Does not affect top-level #ifdefs.

Here "top-level ifdefs" probably means something defined at global scope (outside brackets). Also there is option nl_squeeze_ifdef_top_level to cancel this behavior.

Possible values are true and false, default false.

Examples

true

Before:

int buf_size;

#if defined SMALL_SIZE

buf_size = 10;

#else

buf_size = 100;

#endif

int main()
{
    std::cout << "Buffer will be " << buf_size << '\n';

#if defined SMALL_SIZE

    std::cout << "small size" << '\n';

#endif

    return 0;
}

After

int buf_size;

#if defined SMALL_SIZE

buf_size = 10;

#else

buf_size = 100;

#endif

int main()
{
    std::cout << "Buffer will be " << buf_size << '\n';

#if defined SMALL_SIZE
    std::cout << "small size" << '\n';
#endif

    return 0;
}

Note only #if inside main was affected.

false

Example remains unchanged.
