[completion] Completion scripts not loaded from ~/.guix-profile/etc/profile

[completion] Completion scripts not loaded from ~/.guix-profile/etc/profile

[YOANN P]

Hi guix,

Not sure if it needs to be add to the guix documentation or directly included in "~/.guix-profile/etc/profile" generation process, 
but the completion scripts provided by packages seem not to be loaded.
For example, if i only install the package "git", the completion scripts for "git" reside in "~/.guix-profile/etc/bash_completion.d/git".
But there is no loading instructions for those files in "~/.guix-profile/etc/profile".
So after sourcing "~/.guix-profile/etc/profile", a user need to loop over files in "~/.guix-profile/etc/bash_completion.d/" 
and "~/.guix-profile/share/bash-completion" to source them manually because native bash/bash-completion from the user distribution 
are not aware of the new completion scripts available in "~/.guix-profile/etc/bash_completion.d/" and  "~/.guix-profile/share/bash-completion".

I think a "bash loop" need to be added for this purpose in the generation of "~/.guix-profile/etc/profile" and in the meantime add a section for this
inside "2.6 Application Setup" section be cause i didn't find any instructions about this on the documentation.

Regards,
Yoann

I think was is needed is to install the 'bash-completion' package.  On
the Guix System, this is was gets run at login (/etc/profile, which
sources /etc/bashrc):

--8<---------------cut here---------------start------------->8---
# The 'bash-completion' package.
if [ -f /run/current-system/profile/etc/profile.d/bash_completion.sh ]
then
  # Bash-completion sources ~/.bash_completion.  It installs a dynamic
  # completion loader that searches its own completion files as well
  # as those in ~/.guix-profile and /run/current-system/profile.
  source /run/current-system/profile/etc/profile.d/bash_completion.sh
fi
--8<---------------cut here---------------end--------------->8---

I also have this line in my ~/.bashrc, and IIRC it was useful in getting
the completion to work (not sure if it's required anymore):

--8<---------------cut here---------------start------------->8---
# Source the system-wide file.
source /etc/bashrc
--8<---------------cut here---------------end--------------->8---

HTH,

Maxim
