I’m using neovim (nvim) and seeing shell completion doesn’t exist (in bash, try: nvim -[tab] and nothing happens). How do I neovim’s completion scripts sourced? Sorry I couldn’t find this answered before!
I’m new to nixos and struggling to understand where any given package’s shell completions live, so I welcome a more general answer too.
to this broader point: I’m hitting this with yet another command: gradle; I have gradle-completion installed via configuration.nix but no completion seems to be happening. I’m trying to debug… I see that https://pkgs.on-nix.com/nixpkgs/gradle-completion shows there should be something under an “out” dir at /share/bash-completion/completions/gradle - but where is that out dir? And should it already be sourced by something for me or do I need nixos specific sourcing logic in my bashrc?
I found and installed bashInteractive, bash-completion, nix-bash-completions but still no changes and I’m not clear on if bashInteractive is really supposed to be solving anything I’m confused about here…
Bash completions are enabled with the programs.bash.enableCompletion option. It should be enabled by default. You can see the implementation if you click the source link on the search page - it disables completions in bash versions that don’t support it. Maybe get rid of the additional bash packages, just in case 
Is your shell running in interactive mode? You won’t get completions if you run a non-interactive shell. Doing some funky things with your bash configuration may also break them, I’d suggest trying this with no configuration first. Try:
bash --norc -i
The way packages work in NixOS is that they’re all installed in their own independent directories under /nix/store. Various parts of NixOS will look at the subdirectories in their package directories, and do things with them - bin directories in packages are added to your PATH, and indeed, completion scripts in that subdirectory should be automatically found by bash.
I’ve found this to work for me more often than with other distros 
If you can’t figure it out, share your config (including bash config), maybe someone here can spot it.
The fact that nix packages work this way means you can have multiple versions of the same package installed, in theory without interference (but well, running two graphics drivers is impossible due to physical limitations, to run two versions of Xorg you need at least two ttys… It works well for things like python, though).
tl;dr still no luck even with --norc -i; maybe understanding how it usually works correctly in nixos will give me something to debug 
Couple questions below…
Can you clarify which packages you’re saying I might try to get rid of? Comment out all the bash* ones except bash itself in my system packages?
Is your shell running in interactive mode?
Yes, otherwise most of the output from my own bashrc wouldn’t run (since [[ ${-} = ${-/i/} ]] && return has been the first line of my bashrc for years).
Doing some funky things with your bash configuration may also break them, I’d suggest trying this with no configuration first. Try:
bash --norc -i
Oh good idea - I definitely have some highly customized bashrc. Unfortunately this^ test with --norc didn’t change anything. To clarify here’s a list of programs I’m using in my “does completion work yet?”-test:
lessnvimgradle (particularly since I have gradle and gradle-completion packages)Can you confirm these^ work for you? (or if you have none of htem installed - is there a program you do have that I can use as my litmus test?) Just asking in case there’s actually just something wonky or custom about my selections.
and indeed, completion scripts in that subdirectory should be automatically found by bash.
So the exact mechanics of this - “should be automatically found by bash” - is what I’d like to learn. There must be some standard very specific to nixos that makes it so things “should” work across packages - do you know what that standard is?
I’ve found this to work for me more often than with other distros
haha, fwiw this statement is super valuable - it at least tells me something is just wonky on my end and it’s fixable. My understanding of why this always works for me on Debian is:
$program-name, eg: say nvim (provided by the neovim package)/usr/share/bash-completion/completions/$program-name/usr/share/bash-completion/completions/ and sources it.With nixos however, I don’t know what the analog expectation is - understanding how nixos does it might give me a first-step in debugging my install. The only concrete thing I’ve gotten completion for is a very hand-done step end-users have to do for fzf (sourcing a very app-specific way with this fzf-share hack: https://nixos.wiki/wiki/Fzf#bash)
Just guessing you meant this snippet from me:
So I left only bash in my system package listing and now less actually autocompletes 
but nothing else in my litmus test does 
… hopefully helpful debugging signal.
I’m not familiar enough with the completion stuff to know if this is meaningful, but I assume they have to get sourced somewhere in the chain, so one possibility–if you’ve customized any of your other ~bashrc/profile stuff–might be that a statement in those is returning early and keeping the completions from getting sourced?
thanks abathur. I think this was TLATER’s idea when suggesting bash --norc -i (the --norc ensures my own bashrc doesn’t even run - so I don’t even need to go putting an early return at the top, because it won’t be used).
This has me thinking though: could it be more than bashrc? My understanding is that my ~/.bashrc is the only entry point, but it’s possible that there’s another config file somewhere in my ecosystem that’s causing an issue? 
… As a clean-slate, let me go boot into the 22.05 gnome Live ISO and see what happens…
So to confirm this I spun up one of my servers’ configs in a VM built using nixos-rebuild build-vm. It has a very minimal config for my user (basically only giving them wheel permissions) and no bash or other interactive configuration - it’s a headless server
Trying with less -<tab><tab><tab> (the dash so it doesn’t just complete files) completes for me.
I don’t have gradle installed by default, but using nix profile install nixpkgs#gradle nixpkgs#gradle-completion (note: I don’t recommend using nix profile or nix-env when you’re not in an experimental VM environment, and don’t exactly know the implications of installing things nondeclaratively in your profile) to install it, I get completions for options if I use gradle -<tab><tab><tab>.
I don’t get completions for nvim, but I don’t think that package has completions set up: nixpkgs/pkgs/applications/editors/neovim/default.nix at 316b762afdb9e142a803f29c49a88b4a47db80ee · NixOS/nixpkgs · GitHub. If you know they exist for neovim, and you really want them, I’d suggest contributing.
Other commands where this works for me:
nixos-rebuildfirefoxbashI think I am reasonably confident now that I wasn’t lying, and this is supposed to just work™. But hey, I’ve seen often enough that even NixOS doesn’t always save us from the frailty of software.
Pretty much. But yes, there is still /etc/bashrc, and all the other config that is probably created via your NixOS configuration. Can you usefully share your config?
I’d seen a nice summary of how the completion works before, but can’t find it anymore. I’ll see if I can dig it up some other time!
Ah. Caught me not reading the whole backlog. Not sure. I know there’s a profile, and the corresponding --no-profile flag, but there’s some sort of complexity around their use and the login/interactive shell bits on macOS and Linux that I can never keep straight…
Using --no-profile will completely disable these completions as well, sadly. It gets a lot harder if it’s an issue outside of --norc.
You might also be able to use bash -x to and trawl through the vomit to see if it’s getting to the completions or where it’s stopping?
From /etc/bashrc
# Check whether we're running a version of Bash that has support for
# programmable completion. If we do, enable all modules installed in
# the system and user profile in obsolete /etc/bash_completion.d/
# directories. Bash loads completions in all
# $XDG_DATA_DIRS/bash-completion/completions/
# on demand, so they do not need to be sourced here.
if shopt -q progcomp &>/dev/null; then
. "/nix/store/bcjj9j8xqbwqx4fcsxydya671pgl5nzq-bash-completion-2.11/etc/profile.d/bash_completion.sh"
nullglobStatus=$(shopt -p nullglob)
shopt -s nullglob
for p in $NIX_PROFILES; do
for m in "$p/etc/bash_completion.d/"*; do
. "$m"
done
done
eval "$nullglobStatus"
unset nullglobStatus p m
fi
So nix package completions will happen automatically by the package adding itself to $XDG_DATA_DIRS with its completions in its bash-completion/completions/ dir. (I’ve not actually confirmed this happens; but I trust the comment. Completions work for me.)
progcomp wouldn’t be true in the non-interactive bash, I think, but it sounded like that thread got pulled earlier. set -x should make it clear if that step is falling over or never happening, I imagine.
I felt guilty, so I confirmed it works as described. To do that I
echo $XDG_DATA_DIRS # notice it contains `/run/current-system/sw/share`
ls -al /run/current-system/sw/share/bash-completion/completions/nix
# responds `/nix/store/rrgcc6kzvx9d85b448jga7sdv0z2fzmr-nix-2.9.1/share/bash-completion/completions/nix` or similar
Explore the package dirs /nix/store/rrgcc6kzvx9d85b448jga7sdv0z2fzmr-nix-2.9.1/.

I’m surprised how a lot of stuff is just bash’s own _longopt man-page-scraping hack.
I’m going to go poke at my Debian machine and see what other programs are completed differently. I mean … something must be different because I started this rabbit hole of thinking about completion quality because I was trying on nixos… I can’t remember the last time I cared about (or learned so much about) completion 
I’ll reply to some of the other comments in a bit (thanks everyone)… just wanted to share this tiny bit of progress.
whoa, thanks a lot for finding this! this is very much a mystery I wanted to solve. I unfortunately never thought to read the system-rc scripts because I somehow had the notion they’re be skipped if a user’s own rc is defined. (I think I just assumed it was “magic, elsewhere” that was giving default behaviors )
tl;dr I’m more convinced that I was just confused and maybe nothing’s broken; will get back about comparing with my non-nixos machine to see if there’s anything interesting to share+learn there.
Okay so I’ve learned some things worth sharing… at least for future-me:
complete -p less outputs fzf function now instead of _longopts; it seemed broken because fzf’s func only completes filenames now so CLI flags that _longopts revealed have disappeared).Thanks for sticking with me TLATER (and everyone) despite my tail-chasing - I’ve learned a bunch.
Following up on ericgundrum’s hint, here’s some interesting output show that a lot of packages indeed reveal their completion sources via $XDG_DATA_DIRS’s subpaths.
