completions are "keyed" on the binary name, this is why bb now has its own completions thing. every bb.cli has a standard subcommand when you use dispatch to enable the completions

you need to source the output of that subcommand

So I would have to add it my .zshrc to have it always on. I can do that of course but for this scenario maybe a bit of an overkill and cluttering of my .zshrc

yes, .zshrc

or you can just use bb tasks + exec-fn

Btw is this a typo? https://github.com/babashka/cli#completions:~:text=help%22%5D%0A%20%20%7B-,%3Aprog%20%22myctl%22,-%3Ahelp%20true%7D) It is the only time myctl is being used over mycli

lol, yes, typo

> or you can just use bb tasks + exec-fn Yeah for most projects I would probably do that. In this case I was thinking of distributing a script for people outside of our user group

some tools auto-install their completions

perhaps there's a non-intrusive way to do that

Yeah I really don't know if it is worth that. I just misunderstood how this thing worked. So i thought you would get it always for free, but a bit naive

like not editing a config file, but emitting some piece of config in a separate file. I wonder how other tools in brew do this

ah maybe by convention. Maybe some tools look for certain dirs and if the usr opts in you can register your completion there? I have no idea

What does brew do here?

ChatGPT says this:

Homebrew laat een package zijn completion-bestanden in conventionele directories installeren, bijvoorbeeld:

zsh: $(brew --prefix)/share/zsh/site-functions/_mycli
bash: $(brew --prefix)/etc/bash_completion.d/mycli
fish: $(brew --prefix)/share/fish/vendor_completions.d/mycli.fish

De gebruiker hoeft dus niet per programma iets aan .zshrc toe te voegen. Eén algemene configuratie zorgt dat zsh alle completion-bestanden in Homebrew's directory vindt. Tegenwoordig voegt brew shellenv die directory aan FPATH toe; daarna moet compinit worden uitgevoerd.

sorry for the Dutch ;)

haha dutch is ok

ah yeah ok so it would have to be part of bbin or something similar

I guess we could enhance bbin to do this..

or maybe bbin should have its own completion directory that people add one time to their zsh config

yeah you mean having a completion directory instead of inserting it to .zshr for every command for instance? And then you need the one time config

yeah or maybe doing it like brew could be good, those seem to be the canonical places

perhaps people can add a flag in their bb.edn / deps.edn bbin settings to install the cli completions via a command which then invokes the org.babashka/completions thing

yeah probably you can reuse brew's dir instead of having to manage another dir and configure it. at least on osx brew seems to be the standard

these aren't brew specific dirs

I just wondered how brew did it, but these dirs are more general

ah but brew has the prefix brew --prefix which points to /opt/homebrew here?

But even better if there is a standard

oh yes you're right

the --prefix IS brew specific, hmmm ok

so yeah then it would make sense if bbin had this kind of directory too and people would add it to their zsh once

you can deploy your CLI through brew too btw, it's just a bit more work

I'm wondering how these homebrew completions are loaded though. Don't see it in my .zshrc

I see completion things for other tools, but I would not do this effort for basic tools

> you can deploy your CLI through brew too btw, it's just a bit more work Yeah can do that for this case at least. Probably also makes more sense for the outsiders

Ah homebrew does it via brew shellenv which i have disabled for some reason. So i guess i don't get the completions from homebrew, although for git i get the completions

Like this doesn't show me anything

print -rl -- $fpath | grep -Fx "$(brew --prefix)/share/zsh/site-functions"

Ok good to know it works like this

I also want centralized completions, so I'm very happy to see this discussed! I imagined something like

$ bb completions add mycli

# in ~/.zshrc
source $(bb completions print all zsh)

{:bbin/bin {neil {:main-opts ["-f" "neil"]
                  :completions ,,,}}}

No, I think this should live in bbin. bbin would just execute mycli org.babashka/cli completions and spit it out to the centralized location, that's it

Completions trigger by a certain command name, like mycli

That's just how shell completion works

If you want bb <TAB to work, you need to register that thing as an :exec-fn in bb.edn tasks

here are a few tips how to get a "standalone CLI" with thanks to @lee https://github.com/babashka/cli#creating-a-standalone-cli

Ah cool. Thanks for clarifying
