Elvish completion adapter

It is a BASH adapter.

Requirements:

• bash 4.2+
• elvish 0.17
• kubectl
• helm

Install

epm:install github.com/ezh/elvish-bash-completion

Add to rc.elv

use github.com/ezh/elvish-bash-completion/git
use github.com/ezh/elvish-bash-completion/helm
use github.com/ezh/elvish-bash-completion/kubectl

Aliases

Completer support aliases. It always replaces the first argument with kubectl

An example of adding k alias

fn k {|@arg|
  kubectl $@arg
}
edit:add-var k~ $k~

set edit:completion:arg-completer[k] = $kubectl:kubectl_completion~

Performance

Getting a root level hint on my laptop.

Not bad?

State

I hope that Elvish will be 1st class citizen among other shells, and Kubectl/Cobra will natively support it. Until then, I created an adapter to bash completer that is better than nothing. Ezh.
