GitElephantBundle

This is a simple bundle to use the GitElephant library in a Symfony project.

How to install

Method 1 - composer for Symfony 2.1 and above (recommended)

• Add the following line to the composer.json file:

{
    "require": {
        "cypresslab/gitelephant-bundle": "dev-master"
    }
}

• Execute composer update command

$ composer update

• Register the bundle in the kernel file

app/AppKernel.php

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...other bundles
            new Cypress\GitElephantBundle\CypressGitElephantBundle(),
        );
        // ...other bundles
        return $bundles;
    }
}

Is recommended to register this bundle only in development environment for safety reasons.

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...other bundles
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            // ...other development and testing bundles
            $bundles[] = new Cypress\GitElephantBundle\CypressGitElephantBundle();
        }

        return $bundles;
    }
}

Method 2 - submodules

You can also manage the two git repositories with git and submodules. It could be a mess if you don't know what you do, but I personally prefer this way

$ git submodule add git://github.com/matteosister/GitElephant.git src/git-elephant
$ git submodule add git://github.com/matteosister/GitElephantBundle.git src/Cypress/GitElephantBundle

This two commands will clone the two repositories inside your "src" folder. You can use any folder you want in your symfony project. Just remember to update the app/autoload.php file and to activate the bundle in app/AppKernel.php

The namespace for the bundle is "Cypress". You must clone the bundle in a Cypress folder, or it will not work. Your autoload file should point to the folder that contains the Cypress folder

The GitElephant namespace in autoload should point to the "src" folder inside the GitElephant repository

To actually clone the submodules give the command

$ git submodule update --init

For more info about git submodules read the dedicated section inside the awesome Pro Git book by Scott Chacon.

How to use

To use the bundle you have to define two parameters in you app/config/config.yml file under cypress_git_elephant section

cypress_git_elephant:
    binary_path: /usr/local/bin/git
    repositories:
        "GitElephant": "/home/matteo/libraries/GitElephant"
        "Bootstrap": "/home/matteo/libraries/Bootstrap"
        # ... other repositories

binary_path: (optional) is the path to your git executable. If you don't provide this GItElephant try to argue the right executable with "which git". Remember that this lib only works on *nix filesystems.

Now, inside your controllers, you can easily access the GitElephant library with dependency injection:

repositories: (at least one is required) is an hash with key: a repository name, value: the repository path

The repository path could also be a bare repository (useful for web servers). But without a checked out copy you won't be able to modify the repository state. You will be able to show the repository, but not, for example, create a new commit

class AwesomeController extends Controller
{
    /**
     * @Route("/", name="repository_root")
     * @Template()
     *
     * @param \Symfony\Component\HttpFoundation\Request $request
     * @return array
     */
    public function rootAction(Request $request)
    {
        // Repository instance
        $repositories = $this->get('cypress_git_elephant.repository_collection');
        // There is also an handy alias
        $repositories = $this->get('git_repositories');
        // $repositories is an instance of GitElephant\Cypress\GitElephantBundle\Collection\GitElephantRepositoryCollection
        // it has the Countable, ArrayAccess and Iterator interfaces. So you can do:
        $num_repos = count($repositories); //number of repositories
        $git_elephant = $repositories->get('GitElephant'); // retrieve a Repository instance by its name (defined in config.yml)
        // iterate
        foreach ($repositories as $repo) {
            $repo->getLog();
        }
    }
}

Read the documentation of GitElephant to know what you can do with the Repository class, or watch the demo site build with this bundle, and the relative code.

Web Debug Toolbar

As a bonus, thanks to the GitElephant library, you can have the branch of any repository right inside yuor Symfony2 toolbar.

Add this to your dev configuration file app/config/config_dev.yml

cypress_git_elephant:
    enable_profiler: true
    profiler_repository_path: "%kernel.root_dir%/../"

If you use git with Symfony2, with the above configuration, you can see directly from the browser the branch you are in. Click on the icon and you get a list of the last 10 commits for the branch you are in.

Available console commands

cypress:git:commit

This command is useful to commit (default stage all) all changes in current branch and push to all remotes.

$ php app/console cypress:git:commit [--no-push] [--no-stage-all] [--all] message

cypress:git:tag

This command is useful to tag current commit and push to all remotes.

$ php app/console cypress:git:tag [--no-push] [--all] tag [comment]

cypress:git:merge

This command will merge (default without fast forward) from source (default devel) to destination (default master) branch and push to all remotes.

$ php app/console cypress:git:merge [--no-push] [--fast-forward] [--all] [source] [destination]

cypress:git:hit

Combo command to merge without fast forward option from source to destination branch, tag destination branch and push to all remotes.

$ php app/console cypress:git:hit [--no-push] [--fast-forward] [--all] tag [comment] [source] [destination]

Example

There is also a demo bundle to see it in action.
