I am looking into making usage of different shells easier on GuixSD.
I already noticed that our SLIM-service needs a change
to work for tcsh, but it seems as if we should also create
a file in the %base-services or a small service:
quote man tcsh(1):
Toggle quote (7 lines)
> Startup and shutdown
> A login shell begins by executing commands from the system files /etc/csh.cshrc and /etc/csh.login. It then executes commands from files in the user's home directory: first ~/.tcshrc (+) or, if ~/.tcshrc is not

>
> Non-login shells read only /etc/csh.cshrc and ~/.tcshrc or ~/.cshrc on startup.
It might take a while for me to find time for this and to test it,
but I will try and add such a file (/etc/csh.login) via a service.
However this _seems_ to be only a problem with SLIM as far as I could test,
as I am able to log in using tcsh (in a profile which never used bash and
uses tcsh as its user shell) at the tty. SLIM fails for login_command
reasons. Nevertheless it should be safer to add this for tcsh users
who are new to Guix and who did not add basic stuff to their .tcshrc
such as
Toggle quote (6 lines)

> setenv INFOPATH $HOME/.guix-profile/share/info:/run/current-system/profile/share/info:$HOME/.guix-profile/share/info:/run/current-system/profile/share/info
> setenv GUILE_LOAD_COMPILED_PATH $HOME.guix-profile/lib/guile/2.2/site-ccache:$HOME.guix-profile/share/guile/site/2.2:/run/current-system/profile/lib/guile/2.2/site-ccache:/run/current-system/profile/share/guile/site/2.2
> setenv GUILE_LOAD_PATH $HOME/.guix-profile/share/guile/site/2.2:/run/current-system/profile/share/guile/site/2.2
> setenv GIT_EXEC_PATH $HOME/.guix-profile/libexec/git-core
I will also look at the ~/.guix-profile/etc/profile variant
and see that we can generate a similar file for tcsh.

> export INFOPATH="${GUIX_PROFILE:-/gnu/store/1n2ay00nvsybwszvjdm7acc39pm0k851-profile}/share/info${INFOPATH:+:}$INFOPATH"
a very simple solution could be
setenv INFOPATH $GUIX_PROFILE/share/info
which of course does not include the
Toggle quote (2 lines)
> export INFOPATH=$HOME/.guix-profile/share/info:/run/current-system/profile/share/info
which can be set in /etc/profile so I assume it
could be (untested):
setenv INFOPATH $GUIX_PROFILE/share/info:INFOPATH
We can also test very easily for tcsh if that helps
solving any future problems:
