Hi Akim, I too would start with coreutils, noting that one must be careful to handle signals, so that the terminal is not left in a bad state when output is interrupted between a pair of set/reset escape sequences. https://git.savannah.gnu.org/cgit/coreutils.git/tree/src/ls.c#n1303 Today I was surprised to see that while grep and recent diffutils also have --color support, grep lacks the signal-handling code that is present in both coreutils and diffutils. If you factor some of that code into gnulib, that would be a fine opportunity to use it to fix grep.
