vrk completions

vrk completions generates tab-completion scripts for bash, zsh, and fish.

The problem

A multicall binary has 26 tool names and hundreds of flags. Without tab completion you are guessing names and checking --help constantly.

The solution

vrk completions generates tab-completion scripts for bash, zsh, and fish. After installing, vrk <tab> completes tool names and vrk tok --<tab> completes flags. The completions are generated from the binary itself, so they always match the installed version.

Before and after

Before

# write a bash completion script by hand
_vrk_complete() {
  COMPREPLY=($(compgen -W "tok jwt epoch ..." -- "${COMP_WORDS[1]}"))
}
complete -F _vrk_complete vrk

After

vrk completions bash > ~/.bash_completion.d/vrk

Example

vrk completions bash > ~/.bash_completion.d/vrk

Setup

Bash

vrk completions bash > ~/.bash_completion.d/vrk
source ~/.bash_completion.d/vrk

Zsh

vrk completions zsh > ~/.zsh/completions/_vrk
# Add to ~/.zshrc if not already there:
# fpath=(~/.zsh/completions $fpath)
# autoload -Uz compinit && compinit

Fish

vrk completions fish > ~/.config/fish/completions/vrk.fish

What you get

After installing completions:

$ vrk <tab>
assert   base   chunk   coax   completions   digest   emit   epoch   grab   ...

$ vrk tok --<tab>
--check   --json   --model   --quiet

Tool names and flags are completed from the binary itself, so they always match the installed version.
