Force an old dependency to be installed with Symfony

Question

Updating to Symfony 2.3 is easy if all the dependencies support it. One of the dependency I am using from Packagist says its requirement is Symfony <2.3. Therefore, I cannot install that library.

The library is a little old, and I know there is one or two problems, however, I wish I could still install it with composer.

How can I force composer to install the library dev-master even though packagist says <2.3 ?

You could fork it on github, change the composer.json to your setup of the bundle:

"symfony/symfony":   "2.3.*",

and add the fork as repository in your projects composer.json:

"repositories": [
    {
        "type": "package",
        "package": {
            "name": "youralias/highlight-bundle",
            "version": "dev-master",
            "source": {
                "url": "https://github.com/youralias/HighlightBundle",
                "type": "git",
                "reference": "origin/master"
            },
            "target-dir": "Highlight"
        }
    }

This will then take your fork instead of the original when you require: nicodmf/highlight-bundle

As for the PSR-0

"autoload": {
    "psr-0": {
        "": "src/",
        "Highlight\\": "vendor/youralias/highlight-bundle"
    }
},

And require:

"require": [
    ...,
    "youralias/highlight-bundle": "dev-master"
]
