patch 9.0.1827: xxd: no color support Commit: https://github.com/vim/vim/commit/e2528ae11134cdf35c312754b124aba4963d8054 Author: Aapo Rantalainen <aapo.rantalainen@gmail.com> Date: Thu Aug 31 17:58:13 2023 +0200 patch 9.0.1827: xxd: no color support Problem: xxd: no color support Solution: Add color support using xxd -R Add some basic color support for xxd The hex-value and value are both colored with the same color depending on the hex-value, e.g.: 0x00 = white 0xff = blue printable = green non-printable = red tabs and linebreaks = yellow Each character needs 11 more bytes to contain color. (Same color in a row could contain only one overhead but the logic how xxd creates colums must be then changed.) Size of colored output is increased by factor of ~6. Also grepping the output will break when colors is used. Flag for color is "-R", because less uses "-R". Color uses parameters auto,always,never same as less and grep (among others). E.g. xxd -R always $FILE | less -R Add some screen-tests (that currently on work on linux) to verify the feature works as expected. closes: #12131 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Aapo Rantalainen <aapo.rantalainen@gmail.com>
