I don't install bash-completion into my system profile and I use only

guix home to install user packages. I typically don't guix install any

packages.

While I do include the bash-completion package in my home configuration

file, the completion bash functions do not get loaded as needed, the

resulting user experience is as if bash-completion wasn't installed,

although .bashrc is edited in the typical way to load the main file

bash_completion. But, the shell code in bash_completion cannot find and

load the individual files containing the completion functions for

individual commands.

The reason is that I don't have a ~/.guix-profile folder, my current

user profile is linked in ~/.guix-home/profile. The relevant path (in

my case) is not included in the search path for completion bash functions.

In guix this completion functions search path is defined by the patch found at

gnu/packages/patches/bash-completion-directories.patch, where you can

see the path to the guix home user profile is missing.

The patch below is a patch to the patch file I mention above from the

guix dource tree. It just adds 2 folders to the search path.

I verified that it works for me.

Hi Maze!

That's right, the similiar fix is already applied on core-updates branch

675c5c9bbd28e5e666903aa81efaec25b1573811, unfortunately bash-completion

package update affects a lot of packages that's why it's not on master

branch yet. Thank you for the patch, anyway!

For now, while 1.4 is not released yet, as a temporary fix I can suggest

to install the package providing bash-completion to ~/.guix-profile or

system profile. There are other workarounds, but this one seems to be

the easiest.

It seems $base not needed anymore, it's a rudiment from an old version

of the patch. I'll remove it.

Thanks for the information and right, it is easy to workaround once

figured out. Next time I find a little thing of this sort I'll be sure to

check on the core-updates branch.

Hi,

if anyone else runs into this before the core-updates merge happens, reasonably

simple solution without installing packages into other profiles (or system-wide)

seems to be to add following into services in home definition:

;; TODO: https://issues.guix.gnu.org/57498,should not be necessary after

;; core-updates merge

(simple-service 'guix-home-bash-completion home-bash-service-type

(home-bash-extension

(bashrc (list (plain-file "load-guix-home-bash-completion" "

for f in ~/.guix-home/profile/etc/bash_completion.d/* ~/.guix-home/profile/share/bash-completion/completions/*; do

[ -r \"$f\" ] && . \"$f\"

done")))))

Leaving it here since it might be useful to someone.

There are only two hard things in Computer Science:

cache invalidation, naming things and off-by-one errors.
