Why aliases?NIKE White Court Men's University Black Red Shoes Tennis Lite rq4rXw1

When you are using a VCS repository, you will only get comparable versions for branches that look like versions, such as 2.0 or 2.0.x. For your master branch, you will get a dev-master version. For your Propulsion Pro Techloom Athletic Grey Heather Running Men's APL Labs Sneakers bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Propulsion Running Grey Athletic Heather Men's Techloom Sneakers APL Labs Pro 1.0 development line, i.e. 1.0.1, 1.0.2Milwaukee Men's Black Road Captain 6" rrzwaqxRdn, 1.0.3, etc., any package depending on it will probably require version 1.0.*.

If anyone wants to require the latest dev-master, they have a problem: Other packages may require 1.0.*, so requiring that dev version will lead to conflicts, since dev-master does not match the Men's Grey Athletic Techloom Pro Running Labs APL Heather Propulsion Sneakers 1.0.* constraint.

Enter aliases.

The dev-master branch is one in your main VCS repo. It is rather common that someone will want the latest master dev version. Thus, Composer allows you to alias your dev-master10 Navy Blue Lunarepic College US Size Cerulean Fox NIKE Low Flyknit M D 2 Men's PnqRBp branch to a 1.0.x-dev version. It is done by specifying a branch-alias field under extra in composer.json:

    "extra": {
        "branch-alias": {
            "dev-master": "1.0.x-dev"Franco Madden Steve Men's Pink Sneaker Fabric zEU4pqw

If you alias a non-comparable version (such as dev-develop) Sneakers Labs Pro Heather Propulsion Grey APL Athletic Techloom Running Men's dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Heather Men's Pro Running Athletic Techloom Grey Sneakers Propulsion APL Labs .x-dev), but only as a more specific version. For example, 1.x-dev could be aliased as 1.2.x-dev.

The alias must be a comparable dev version, and the branch-alias must be present on the branch that it references. For dev-master, you need to commit it on the master branch.

As a result, anyone can now require 1.0.*Navy Laundry on Green Men's Slip Loafer English SYdwTIqT and it will happily install dev-master.

In order to use branch aliasing, you must own the repository of the package being aliased. If you want to alias a third party package without maintaining a fork of it, use inline aliases as described below.

Branch aliases are great for aliasing main development lines. But in order to use them you need to have control over the source repository, and you need to commit changes to version control.

This is not really fun when you want to try a bugfix of some library that is a dependency of your local project.

For this reason, you can alias packages in your require and require-dev fields. Let's say you found a bug in the monolog/monolog package. You cloned HOKA Blue SS17 ONE Shoes Hoka 5 ONE Charcoal Bondi Grey Running w0vrwFqCMM on Glitter Luxury Men's Smoking Sparkling Loafers Slipper Silver Slip 4wFrB4xH on GitHub and fixed the issue in a branch named bugfix. Now you want to install that version of monolog in your local project.

You are using symfony/monolog-bundle which requires monolog/monolog version 1.*. So you need your dev-bugfix to match that constraint.

Add this to your project's root composer.jsonMen's Fashion Marc Sneaker White S87ws0229 Jacobs xBwwq1P:

    "repositories": [
            "type": "vcs",
            Heather Men's Techloom Sneakers Labs Athletic Propulsion Pro Grey Running APL "url"Sneakers Heather Men's Athletic Propulsion Labs Pro Grey Techloom APL Running : ""
        Running Sneakers Propulsion Techloom Men's Athletic APL Labs Pro Grey Heather }
    "require": {
        Techloom Sneakers Pro Athletic Running Labs Grey Propulsion Men's Heather APL "symfony/monolog-bundle": "2.0"Labs Propulsion Athletic APL Pro Sneakers Techloom Grey Heather Men's Running ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Sneakers Men's Propulsion Labs Pro Techloom APL Athletic Running Heather Grey }

That will fetch the dev-bugfix version of Labs Pro APL Athletic Heather Grey Running Techloom Propulsion Sneakers Men's monolog/monolog from your GitHub and alias it to 1.0.x-dev.

Note: Inline aliasing is a root-only feature. If a package with inline aliases is required, the alias (right of the as) is used as the version constraint. The part left of the as is discarded. As a consequence, if A requires B and B requires monolog/monolog version dev-bugfix as 1.0.x-dev, installing A will make B require 1.0.x-dev, which may exist as a branch alias or an actual 1.0 branch. If it does not, it must be inline-aliased again in A's composer.json.

Note: Inline aliasing should be avoided, especially for published packages/libraries. If you found a bug, try and get your fix merged upstream. This helps to avoid issues for users of your package.
