This *should* be sound, plus or minus the amount that the terminal code eating code is messed up already. This is useful for testing CLI output because it will strip the escapes enough to just shove the expected output in a file. Change-Id: I8a9b58fafb918466ac76e9ab585fc32fb9294819

Lix now heeds NO_COLOR
/NOCOLOR
for more output types, such as that used in nix search
, nix flake metadata
and similar.
It also now supports CLICOLOR_FORCE
/FORCE_COLOR
to force colours regardless of whether there is a terminal on the other side.
It now follows rules compatible with those described on https://bixense.com/clicolors/ with CLICOLOR
defaulted to enabled.
That is to say, the following procedure is followed in order:
-
NO_COLOR or NOCOLOR set
Always disable colour
-
CLICOLOR_FORCE or FORCE_COLOR set
Enable colour
-
The output is a tty; TERM != "dumb"
Enable colour
-
Otherwise
Disable colour
