I find this bash script useful:
--8<---------------cut here---------------start------------->8---
#!/usr/bin/bash
echo "----from apropos:"
guile <<EOF | grep ": ${1:-help}"
,a ${1:-help}
EOF
guile <<EOF | tail -n +9
(display "----describe:\n")
,d ${1:-help}
(display "----\n")
EOF
--8<---------------cut here---------------end--------------->8---
Just name it, e.g., guap (for GU.ile AP.ropos :)
chmod 755 guap
then try e.g.
guap string=
--8<---------------cut here---------------start------------->8---
----from apropos:
(guile): string= #<procedure string= (_ _ #:optional _ _ _ _)>
(guile): string=? #<procedure string=? (#:optional _ _ . _)>
----describe:
- Scheme Procedure: string= s1 s2 [start1 [end1 [start2 [end2]]]]
Return `#f' if S1 and S2 are not equal, a true value otherwise.
----
--8<---------------cut here---------------end--------------->8---
Have fun tailoring to suit yourself.
Maybe some variations on restricting
the apropos output better than my grep :)
Or add some other ,xxx stuff or guile code to taste.
Note that you can of course invoke guap from emacs
like inserting the output of any bash command, as I did
for the above snip (writing this in emacs as mutt's editor choice).
