This GitHub action allows to run the latest composer on your source code.

It uses the official composer docker image and allows efficient caching of downloaded assets.

• composer_version: Major version to install. Basically any tag name from https://hub.docker.com/_/composer - i.e. 1 or 2. Defaults to latest.

• command: The composer command to run, defaults to install. Set to get_config to only generate the output variables of the composer setup (for use in cache, see example below)

• args: Other command line arguments to pass to composer, defaults to --optimize-autoloader --no-progress

• github_oauth: If your composer needs access to a private repo, configure the github OAuth token to use here. For example it could come from a secret, i.e. secrets.GITHUB_OAUTH.

• composer_cache_dir: where the composer cache is located, in case you want to use actions/cache

• composer_major_version: the detected major version of composer, useful to have a separate cache tag based on this, since there can be slight differences in the caches between major versions.

• composer_version: the exact composer version, in case you want to output this somewhere.

The idea came after some brainstorming in https://github.com/php-actions/composer.
