README

This Composer plugin allows you to install packages as local symbolic links, with the option to fallback to other install options. This allows you to locally develop a package and its dependencies in parallel.

This has been discussed as a possible improvement to Composer, but movement has been slow. See Composer issues #1299, and #4011 for example discussions.

This is a fork of piwi/composer-symlinker with some enhancements. Specifically:

  • Allow for relative paths (helpful if you develop in a virtual machine, but edit code on your host machine)
  • Fall back to other install options, if a package can't be found locally.
  • Allow for other installers to give the correct install path. (Useful when using packages that install to non-vendor locations)

Setup

First, add the plugin as a dependency in your composer.json:

"socialengine/composer-symlinker": "~1.0"

Next, define local paths to your packages in an extra section of your composer.json. You have two options on how to declare the paths:

  • local-dirs: list out directories to look in for packages. When scanning, these paths will be combined with vendor/package.
  • local-packages: a key-value object, where the key is the package name, and the value is a path to that package. The paths can be relative to the composer.json.

If you want to restrict which vendors to scan for locally, you can add a local-vendors list.

If a package is not found locally, the plugin will fall back to other install methods (like packagist/git).

Example Extra Section

"extra": {
    "local-dirs": [
        "/my/absolute/local/path1",
        "../../relative/local/path2"
    ],
    "local-vendors": [
        "vendor1",
        "vendor2"
    ],
    "local-packages": {
        "vendor/package1": "/my/absolute/path/to/vendor/package1",
        "vendor/package2": "../relative/path/to/vendor/package2"
    }
}

Example Setup

Let's say we want to work on a project named MyProject base on three dependencies: MyPackage1 and MyPackage2 which are some of our packages, and a third-party ExternalPackage which is not.

Further, MyPackage1 is located at /opt/php/MyVendor/MyPackage1 and MyPackage2 can be found at ../my-package-2.

We can configure our composer.json like so:

"require": {
    "MyVendor/MyPackage1": "3.6.1",
    "MyVendor/MyPackage2": "0.10",
    "OtherVendor/ExternalPackage": "2.4.6"
},
"require-dev": {
    "socialengine/composer-symlinker": "~1.0"
},
"extra": {
    "local-dirs": "/opt/php/",
    "local-packages": {
        "MyVendor/MyPackage2": "../my-package-2"
    }
}

So, when developing on our local box, composer install will install our packages as symlinks to their respective paths. If use the same composer.json on a box where the paths aren't valid, the packages will be installed normally.

Windows users warning

The plugin uses the internal symlink() PHP function. See Windows restrictions on the manual.
