Hi Guix,

under “guix/scripts” there are a couple of tools that are really useful,
such as “guix challenge”.  While they are great for the command line,
I’d really like to use them from within Guile.

Using “(guix-challenge)” directly is cumbersome, because I need to
provide an argument list “args”, which is then parsed internally.
Instead, I’d like to be able to say

   (challenge #:urls (list "a" "b")
              #:packages (list foo bar baz))

and have it produce some report values.  Then “guix-challenge” could be
implemented in terms of “challenge”.

The same might be useful for “guix-build” or “guix-environment”.

What do you think?

I agree. This would also enable more flexible cli possibilities, and
would be really useful for scripting. Does this idea fit to the
improve command line tools outreachy idea?

The outreachy project is about making the *output* of Guix prettier and
less cluttered, so this would not be part of that project.

I see, then I'm willing to help you out with this, if we decide to
implement it.
I would wait for some more opinions thou.

I think ‘compare-contents’ in (guix scripts challenge) is close to what
you want, no?  See tests/challenge.scm for example usage.

The short-lived reproducibility.html generator also used it:

  http://git.savannah.gnu.org/cgit/guix/guix-artwork.git/tree/website/www/packages.scm?id=ae2d0209cc44e25a45cab0abcc9d85172fd48dca#n545

I agree with this sentiment!

Then it’s a matter of defining an appropriate API.  For instance, all
‘guix-build’ does is UI stuff around (guix store) and (guix packages).
There’s a higher-level ‘build-package’ procedure in (guix scripts).

IMO a good interface can’t just be a Schemey variant of the CLI, because
often the CLI papers over a number of details that a good API should
expose.
