Allows to use a composer.override.json next to your composer.json file for external package management. This is useful, in example, when you need to have packages symlinked for local development, but not for production.

This tool will not use an existing composer.lock-file, so pulling may be slower. It will also not modify the existing lock file, if you need this, you can pass --copy-lock as parameter, and will copy the created lock file to the directory where the tool is run from.

Please note that php-cli 5.6+ should be installed on your system, as well as Composer.

Run the following script on any Linux based machine: If you wish a different path than /usr/local/bin you can modify the last two lines.

wget https://raw.githubusercontent.com/FaimMedia/composer-override/master/composer-override -nv -O composer-override

php -r "if(hash_file('md5', 'composer-override') !== '2d2d98355db4bf9893e2689c4f2cf490') { print \"Invalid checksum\r\n\"; exit(1); }" \
	&& sudo mv composer-override /usr/local/bin/composer-override \
	&& sudo chmod +x /usr/local/bin/composer-override

composer.json

{
	"name": "faimmedia/my-app",

	"require": {
		"faimmedia/my-library": "^1.0"
	}
}

Next create a composer.override.json file next to the composer.json file:

composer.override.json

{
	"repositories": {
		"faimmedia/my-library": {
			"type": "path",
			"url": "../faimmedia-my-library",
			"symlink": true
		}
	}
}

When running composer-override it will merge the two files together, giving precedence for the override file, and will now create a symlink to a local directory, instead of pulling the package from Packagist.

You may override or add any value, in example:

composer.override.json

{
	"require": {
		"faimmedia/my-library": "dev-master"
	},

	"config": {
		"platform-check": false
	}
}
