Some emacs stuff to activate/deactivate guix profiles

Some emacs stuff to activate/deactivate guix profiles

[pinoaffe]

[-- Attachment #1: Type: text/plain, Size: 753 bytes --]

Hi guix!
    
I wrote some elisp that
* maintains a list of available guix profiles
* maintains a list of active guix profiles
* allows the user to modify both of those lists
* provides interactive commands that allow the user to (de)activate profiles
* sets env variables and the emacs search path based on active profiles
I may add the ability to "update" a profile from a manifest.

This allows me to have a profile with, say, reverse engineering tools,
and to (de)activate it whenever I do(nt) need those tools.

Please not that I'm fairly new to all of this emacs stuff, so it may not
be idiomatic or good code.

I've attached the reusable stuff in guix-profiles.el, and my personal
config in init-profiles.el.

Any thoughts?

Blessings,
pinoaffe

Thanks for sharing.

Instead of call shell command and then…

…parse the output, you should give a look at how Emacs-Guix does using
the Scheme API.  Or maybe use “guix repl” as Nyxt does.


Aside, it is a bit redundant with Emacs-Guix, from my understanding. :-)

All the best,

Thanks for the suggestion, I'll look into that

It might very well be, but I couldn't find a way to do what I wanted to
do with emacs-guix

I guess the entrypoint is ’guix-set-emacs-environment’.  But I have not
looked into the details of your code, neither checked if the Emacs-Guix
is currently working as expected.

<https://github.com/jsoo1/guix.el/blob/master/elisp/guix-misc.el#L225>

I understand though that the learning process is often easier by doing
by their own instead of adding or fixing the wanted feature with an
existing code base. :-)

My emacs-guix already has a file called guix-profiles.el; how do you
handle that or how do I best look at / try your profiles?

This looks interesting; I'm using M-x guix-set-emacs-environment a
lot but my biggest problem/gripe with that is that it's global.

oops, I think I'll rename this script then :)

I think the easiest way to try this is to source the guix-profiles file,
set the three "defcustom" variables, and to then run guix-enable-profile
or guix-disable-profile interactively.

Yeah this is also global, as far as I can tell the only difference with
guix-set-emacs-environment seems to be that this allows enabling several
profiles at the same time and that this script maintains a list of which
profiles should be active. I think I'll take a look at how this could be
integrated into emacs-guix.
    
As to non-global things: I think a way to open a shell in emacs with a
specific set of packages available would be nice, but I'm not sure
whether it'd be better to wrap `guix environment` or to implement
something that starts a subprocess with the environment variables
corresponding to a (set of) profile(s). When implemented correctly, this
could also be applied through per-project profiles when combined with a
project manager such as projectile.
