Globally disable color?

[saper]

I cannot find the way to globally disable color in the pre-commit output. Setting only the background color to green and not changing the foreground color does not work for my terminal with the following settings in the Xt resources (as set in the ${HOME}/.Xresources file):

Rxvt.background: black
Rxvt.foreground: deepSkyBlue

Is there a way? It would be great to respect https://no-color.org/ environment variable. And, while we are here, maybe understand the following git config setting:

[color]
        ui = never

[asottile]

There's --color

[saper]

Thanks, how do i do this from the git pre-commit hook?

[asottile]

currently not an option afaik

[asottile]

@saper would you like to implement $NO_COLOR or some such? shouldn't be too difficult to plug in here

[geieredgar]

I submitted two PRs to disable color output via NO_COLOR environment variable (#1092) and deducing the right --color option from color.ui config value when run as git hook (#1091)

[saper]

This is fantastic @geieredgar ! Thank you very very much!

[asottile]

I've had more thought about this and I think NO_COLOR is kind of a bad standard and inflexible for pre-commit

@geieredgar would you mind reimplementing this as reading PRE_COMMIT_COLOR and having that be the default of the --color argparse option -- that would allow also forcing color on as well as off

[geieredgar]

@asottile Ok, I will submit a new PR soon.

[asottile]

I'm also going to have TERM=dumb disable colors as well -- see #1103

[asottile]

@geieredgar and @saper -- thanks again for the issue and implementation!

In the next minor release, pre-commit will have two ways to force color:

PRE_COMMIT_COLOR=...  # always, never, auto
TERM=dumb  # disables color
