PHP Ctagger is a Composer script that will create a ctags tag file for a project's autoloadable library and that project's dependencies. The tag file will be placed in your project's root directory at /tags.

The only supported method of installation is via Composer. As PHP Ctagger is intended to be used in a development environment (and will only create a tag file when Composer is in dev mode), PHP Ctagger must be installed as a dev dependency. Add the following to your composer.json.

{
    "require-dev": {
        "jeremykendall/phpctagger": "dev-master"
    }
}

PHP Ctagger utilizes Composer's Scripts functionality. In order for PHP Ctagger to build your tag file, the script must also be added to your composer.json.

{
    "scripts": {
        "post-install-cmd": [
            "PhpCtagger\\Composer\\Script\\Ctagger::ctag"
        ],
        "post-update-cmd": [
            "PhpCtagger\\Composer\\Script\\Ctagger::ctag"
         ]
    }
}

In this example, the script will run both post install and post update.

With that done, run composer update --dev to install PHP Ctagger and build your tag file.

Ensure you're running the most recent version of ctags. This is especially important on OSX, as the wrong version of ctags is installed by default.

This initial implementation is extremely naive, and will only create tags for libraries and dependencies that have path entries in /vendor/composer/autoload_namespaces.php.

In order to use your new tag file, vim needs to know about it. Make sure to load your tag file via whatever means you feel most comfortable. I've placed the following in my .vimrc

set tags=tags

This project is in its alpha stage, and I'm still not sure if it's even a good idea. It's been fun to play with so far, so that's good. Pull requests, new issues, comments, and constructive criticisms are welcome.
