Emacs tip: navigate (and fuzzy search!) your package definitions

Emacs tip: navigate (and fuzzy search!) your package definitions

Hi Guix!

At FOSDEM I realized that many Guix users/developers and Emacs users did
not seem to know about a nifty trick: M-x imenu (or better: helm-imenu
and helm-imenu-in-all-buffers or some Ivy/Counsel equivalent) allows you
to navigate through the package definitions in the .scm files.

This is super handy to jump from package definition to package
definition when you know which one you are looking for.

Unfortunately, Emacs' scheme-mode still has a bug and does not parse
"define-public" properly.  Alex Kost has a patch:
https://gitlab.com/alezost-config/emacs/blob/master/utils/al-scheme.el

Put the above file in your Emacs' load-path and add a "(require
'al-scheme nil :noerror)" to your Emacs' config.

(By the way I've reported the issue and Alex' patch upstream -- still no
answer.)

Hope you find it handy!

Cheers!

I like ivy-imenu-anywhere from the imenu-anywhere package (which also
provides helm and ido versions).

imenu is one of the great ideas in GNU Emacs that does not get enough
exposure. If you work on a GNU Emacs major mode you should definitely
think about how you can provide information via imenu.
