Bun autocomplete for bash

bun-completion.sh

#!/usr/bin/env bash

_bun_complete() {
    local cur prev opts
    COMPREPLY=()
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"

    # Define the main commands
    local commands="add build create exec init install link outdated patch pm publish remove repl run test unlink update upgrade x"

    # Define some common flags
    local flags="--watch --hot --no-clear-screen --smol -r --preload --inspect --inspect-wait --inspect-brk --if-present --no-install --install -i -e --eval -p --print --prefer-offline --prefer-latest --port --conditions --fetch-preconnect --max-http-header-size --dns-result-order --expose-gc --no-deprecation --throw-deprecation --title --silent --elide-lines -v --version --revision -F --filter -b --bun --shell --env-file --cwd -c --config -h --help"
    local scripts=$(bun getcompletes s)

    case "${prev}" in
        bun)
            COMPREPLY=( $(compgen -W "${commands} ${scripts}" -- ${cur}) )
            return 0
            ;;
        run)
            COMPREPLY=( $(compgen -W "${scripts}" -- ${cur}) )
            return 0
            ;;
        *)
            # For other commands, suggest flags or nothing
            COMPREPLY=( $(compgen -W "${flags}" -- ${cur}) )
            return 0
            ;;
    esac
}

complete -F _bun_complete bun

Made this pretty quickly with feeding the output of bun --help to an LLM and asking it to generate a Bash autocomplete script and follow-up to adjust the run output to limit it just to scripts.

Nice! FYI you can get the current list of script entries from package.json by running bun getcompletes s

The Fish completions file is a good place to learn more: https://github.com/oven-sh/bun/blob/c8f8d2c0bbc80a747ec0235b390866d043dc1d9f/completions/bun.fish

Thanks, @mangs!

You're very welcome. I've been down this rabbit hole before. 😀
