Allow to disable colors (or automatically disable colors if stdout is not a tty)

[felipecrs]

I'm writing a script that uses gext to detect whether some extension is installed or not:

gext list | grep --quiet "(arcmenu@arcmenu.com)"

But this doesn't work because gext's output is colorized and therefore grep doesn't match.

The workaround is https://stackoverflow.com/a/51141872:

gext list | sed 's/\x1B\[[0-9;]\{1,\}[A-Za-z]//g' | grep --quiet "(arcmenu@arcmenu.com)"

But I believe this could be better handled by gext itself. For example, it could disable colors automatically when the stdout is not attached to a terminal (i.e. running in a pipeline).

Hi

This is an excellent point.
When I tried to write an alternative to colorama I added an env variable to globally disable the colors and styles.

I choosed colorama over pytput to handle styles in this project, I did not think about this.

I'll develop a solution in gext since this is a totally valid point, idk if it will be an env var or an argument yet.

After some research, there is no existing feature for now working with an env variable.

There was a PR that was closed without merge.

But I think I'll go with the solution proposed here, kudos to thetasine.
