CLI auto completion

[octref]

Something npm has always bugged me is auto completion.

It requires putting source <(npm completion) to my zshrc, which is extremely slow and seldom outputs useful completion.

A few examples yarn could do:

letting yarn <Tab> outputs all commands:

install -- install package
remove  -- remove package
...other commands

letting each flag output useful information:
yarn install -<Tab>

-g -- install package globally
-S -- install package and save as dependency

letting yarn install <Tab> prompt a list of cached packages:
yarn install r<Tab>

react@0.14
redux@3.0

letting yarn rm <Tab> list packages installed locally
yarn rm r<Tab>

react@0.14
redux@3.0

Thanks for the good work!

Hi I came here to suggest an auto-completion feature for yarn. Saw this so thought I'd comment here to flag my interest. Yarn like npm has a lot of commands and I often use npm's auto-completion. Would help people switching to yarn.

There is yarn-completions

There is also a completion-plugin for oh-my-zsh.

@cjk How does that even work?

I installed yarn-completions - didn't work. Realized it's actually some kind of plugin for tabtab, so I installed that. Still doesn't work. Re-sourced my bash profile. Still doesn't work. Is there really more configuration required?

It'd be really nice to have this functionality included in yarn itself.

@cjk yarn-completions works great, thanks for the suggestion!

It would be very useful to include that plugin into Yarn itself

@Matmo10 did you ever get completions working?

[Matmo10]

@wavded Yep (mklabs/yarn-completions#8)

Didn't see @Matmo10's comment unfortunately.

I spent the day today writing a pretty feature-complete bash completion, including computed autocomplete for scripts, local and global package names, and more.

If anybody is still in the market for it, you can find it here. https://github.com/dsifford/yarn-completion

Maintainer: If this is something you'd like for me to PR into this project directly, I'd be glad to do that as well.

Thanks 👍

I'm thankful for that, because your solution is much better 👍
