Hi Guix,
this patch set is a first draft to stylize (potentially confusing) build
output when using “guix package” and “guix build”.
This is done by adding a soft port that matches on lines in the build
output and colorizes them (unless INSIDE_EMACS or NO_COLOR are set, or
when output is redirected). For “guix package” the default behaviour is
to also hide all build output that does not announce progress (unless
“--verbose” is passed) and to let a spinner show progress instead. For
“guix build” all build output is still printed.
Honestly, I’m not really happy with the results, but I think it’s enough
to start a discussion about where this should lead.
One thing I don’t like is that I had to set the “print-build-trace?”
default option to be able to display what build is currently happening.
Unfortunately, for small derivations this leads to output like this:

I would prefer:
Building /gnu/store/rh92rslbj4x9abyna6lc11jqifbavx13-librsvg-2.40.20.drv …
DONE
or similar.
I don’t know about whether the colours are any good; I think the bold
green is hard to read on a bright terminal, while the black is hard to
read on a dark terminal.
Lastly: the spinner. It’s a bit boring, I think.
What do you think? Is this a step in the right direction?
