I am looking into making usage of different shells easier on GuixSD.I already noticed that our SLIM-service needs a changeto work for tcsh, but it seems as if we should also createa 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> found, ~/.cshrc, then the contents of ~/.history (or the value of the histfile shell variable) are loaded into memory, then ~/.login, and finally ~/.cshdirs (or the value of the dirsfile shell variable) (+). The> shell may read /etc/csh.login before instead of after /etc/csh.cshrc, and ~/.login before instead of after ~/.tcshrc or ~/.cshrc and ~/.history, if so compiled; see the version shell variable. (+)>> 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 anduses tcsh as its user shell) at the tty. SLIM fails for login_commandreasons. Nevertheless it should be safer to add this for tcsh userswho are new to Guix and who did not add basic stuff to their .tcshrcsuch as
Toggle quote (6 lines)> setenv PATH $HOME/.guix-profile/bin:$HOME/.guix-profile/sbin:/run/setuid-programs:/run/current-system/profile/bin:/run/current-system/profile/sbin> 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 $HOME/.guix-profile/libexec/git-core
I will also look at the ~/.guix-profile/etc/profile variantand see that we can generate a similar file for tcsh.
Toggle quote (2 lines)> export INFOPATH="${GUIX_PROFILE:-/gnu/store/1n2ay00nvsybwszvjdm7acc39pm0k851-profile}/share/info${INFOPATH:+:}$INFOPATH"
a very simple solution could besetenv 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 itcould be (untested):
setenv INFOPATH $GUIX_PROFILE/share/info:INFOPATH
We can also test very easily for tcsh if that helpssolving any future problems:
Toggle quote (8 lines)> [abyayala] 8:08am ~ > echo $shell> /gnu/store/kfv79p5di3bz3jl4j1vn91v69ga6sqk3-tcsh-6.20.00/bin/tcsh> [abyayala] 8:08am ~ > exit> # now we are back in bash again (no tcsh-only environment here)> user@abyayala ~$ echo $shell>> # as you can see bash returns empty here> # and so does zsh aswell.
