Hello!
Konrad Hinsen <konrad.hinsen@fastmail.net> skribis:
> * guix/scripts/repl.scm: Add filename options for script execution.
> * doc/guix.texi (Invoking guix repl): Document it.
> * tests/guix-repl.sh: Test it.
I like it!
It cannot be used as a shebang, can it?
There’s also the Makefile.am change that could be mentioned in the
commit log.
Some comments:

I’d remove “$” from the examples.

s/filename/file name/

I think this change is unnecessary (see below).

^ ^
Please add a space and change comma to period.

I’d change that to just:
(append `((script . ,arg) (ignore-dot-guile . #t)) result)
and later we can collect all the values associated with 'script.
I think “script” is clearer than “script-args” (and more in-line with
the naming conventions.)
Last but not least: I think -q should always be implied when running a
script. ~/.guile is really meant for the REPL, nothing else.

Please move the comment to the bottom, outside the parens, as before,
otherwise this paren will feel lonely. :-)
Thoughts?
Looks like we’re almost done. Thank you!
