Adding shell commands the .profile with guix home

Adding shell commands the .profile with guix home

[Andrew Stubbs]

Hi,

I'm trying to figure out how to run a shell command once on SSH login,
but not in nested shells. Traditionally I've simply appended it to
.profile, but I want to switch to use guix home and I can't figure out
how. (I got my environment variables and arbitrary dot-files done.)

The manual suggests that "home-shell-profile-configuration" is the way
to go, but there's no example given.

I found this example from an old mailing list post:

(service home-shell-profile-service-type
         (home-shell-profile-configuration
          (profile '("echo hi" "source ~/.xprofile"))))

But that fails:
 error: (service home-shell-profile-service-type
(home-shell-profile-configuration (profile (quote ("echo hi" "source
~/.xprofile"))))): invalid field specifier

What's the correct way to do this, please?

Thanks

Andrew

The home-shell-profile-service-type is the way to go, but due to the way
the service is included (as an essential service), you need to add items
to the configuration using a service extension.

The example you provided might look like this instead:

  (simple-service 'sourcing-xprofile home-shell-profile-service-type
                  (list (plain-file "shell-profile" "echo hi; source ~/.xprofile")))

The items of the list can be any "file-like" gexp (e.g. the results of
local-file, mixed-text-file, file-append).

I hope that helps,

Carlo

Thanks, this is what I needed.

Can we get something like this example added to the manual? I now see
that the bash example is similar, but this stuff was really not
obvious to me. The "type text-config" is also presented, throughout
the manual, entirely without explanation, but maybe that would be
clear to me if I knew more about scheme/guile?

Thanks again

Andrew
