Activate multiple profiles inside emacs

Activate multiple profiles inside emacs

[Reza Housseini]

Hi Guix

Say I have several projects each with their specific profile containing 
the needed dependencies and a profile for all my Emacs specific stuff.

Now I want to work on a projects inside Emacs and make therefore a union 
of the project specific profile and my Emacs profile. So as for example 
pylint does not complain about missing modules inside my project source 
code.

As I understand I could source my needed profile files in a shell and 
then start Emacs from there, but this makes it quite cumbersome to 
switch projects as I have to restart Emacs every time.

Is there a possibility to achieve the same while Emacs keeps running?

How do you guixers handle this scenario? Or is there an obvious solution 
to my needs?


Thanks for any input!


Cheers,

Reza

I use direnv for this. You could set up your profiles, then, in the envrc, source all of them in order(I personally would keep sourcing the emacs specific profile separately though). There is a package (emacs-direnv) which integrates emacs and direnv which makes the sort of workflow you are describing seamless.

Cheers.

Typically, I keep a manifest.scm per project, then create the
environment with 'guix shell', retrieve the profile link with 'echo
$GUIX_ENVIRONMENT' within that environment, which I then pass to the
'guix-set-emacs-environment' Emacs procedure, which is provided by the
'emacs-guix' package.

Clunky, but it works for me.

Hope that helps,
