bug#48530: Guile Mode

["Jérémy Korwin-Zmijowski" <jeremy@korwin-zmijowski.fr>]

Dear Emacs team,

I am Jérémy, an Emacs and Guile user. I came to discover both in the
same time about three years ago.
I am not a member of the GNU project, nor FSF. I'm just a GNU
enthousiast.

When I edit Guile code in Emacs, I rely mostly on :
Scheme mode + Geiser + Paredit + Autocomplete/Company + Projectile +
Magit

Then come other extensions.

I am writing to you today to start a conversation (hopefully a work)
around a kind of "Guile mode" (why not something with IDE
capabilities). I remember Eli incentivizing people to do so on Guile
user mailing list.

I don't know the spirit and the boundaries of the Emacs project.
Here is a list of things that I would like to be able to do in Emacs
while writing Guile code.
(I would like to know if there are things that fit to the scope of your
project ? For the ones that do not, I will contact the relevant
stakeholders.)

- take in charge the support of Geiser for Guile ?
- provide features to "refactor" Guile code (i.e extract a
value/procedure into a local/top-level define or let expression, toogle
a variable to be private or public, change procedure signature and
propagate change, move to another file/module and auto-import it) ?
- auto import Guile modules according to unbound variables ?
- instrument the code (set and stepover breakpoints)

Thank you,
Jérémy
