bash-completions-getter.sh: line 178: _completion_loader: command not found

[wentasah]

I'm trying to make this work on NixOS and I'm getting the following error:

/nix/store/0ibqj2ysg8602by5azn2rgm64w6gmsnd-source/bash-completions-getter.sh: line 178: _completion_loader: command not found

It seems that when bash is run in non-interactive mode, this function is not defined on NixOS. I can resolve the issue with the following change, but I'm not sure how generic it is and whether it would work on other distributions.

well, it would likely work in other platforms, but indeed will make things slower (depending on your default default .bashrc)

Maybe, can you try if instead you can just try to ensure that a function defined in /usr/share/bash-completion/bash_completion (or well yours) exists and in such case source it? Would be that enough?

Otherwise, something else we could probably do for everyone is something like this:

env HOME="/tmp/fooo" DEFAULT_HOME="$HOME" bash -i -c "export HOME=$DEFAULT_HOME; echo do stuff in $HOME"

So that we won't ever end up loading the user's .bashrc, but we still be using its HOME for other stuff.

Mh, loading the bash_completion is actually already happening, so what I assume is that we're picking the wrong location in your setup. Where is the bash_completion script?

I assume you've to fix source_bash_completion function in bash-completions-getter.sh instead, can you maybe do a PR?
