Bash/Shell Autocompletion for Composer

The other day I opened up a PHP project that I hadn’t worked on in a while. No longer remembering which Composer Scripts I had defined for it, I needed to take a peek inside composer.json to see which ones were available to me. Then it hit me: why is there no autocompletion for composer available?

Googling around a bit I eventually turned to creating my own Bash completion script for Composer. After installing it, it will autocomplete composer commands for you:

$ composer in[TAB][TAB]
info     init     install

The code builds further upon this earlier work by Rob Allen. Key area where it differs from Rob’s work is that composer-autocomplete also provides autocompletion for composer run-script, listing which Composer Scripts are available to you (as I initially wanted).

{
    "name": "bramus/example-php-package",
    "description": "Example PHP Package",
    "type": "library",
    "license": "MIT",
    …
    "scripts": {
        "test": "./vendor/bin/phpunit --colors=always",
        "lint": "php-cs-fixer fix --diff --dry-run --ansi",
        "fix": "php-cs-fixer fix"
    }
}

$ composer run-script [TAB][TAB]
fix   lint  test
