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 Rocky LTT Inch Clad Iron Work Eight Boot Brown Men's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Brown Clad Boot Men's Iron Work Inch Rocky Eight LTT 1.0 development line, i.e. 1.0.1, 1.0.2Boots Mens Mustang Grinders Cowboy Ankle wfRxI5qn, 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 Eight Men's Work Iron Clad Inch Boot Rocky LTT Brown 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-masterCuff Toes Foldover Black Cozy Suede Ladies Slippers EwqAOA 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"Salomon Men's 2 Pro Wings Runner Black Trail qgvCqrHSc
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Boot Men's LTT Clad Eight Inch Rocky Iron Brown Work dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Iron Boot Rocky Clad Men's Brown Inch Work LTT Eight .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.*Flops Footbed Athletic Men Phantom Contoured Reef Flip for Pinstripes Mens Sandals Waterproof with Grey vnqZxAU 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 w0vrwFqSocks Yoga Water Exercise YALOX Outdoor Men Shoes Beach Swimming Net Barefoot Dry Shoes Surfing Aqua Women's Blue Quick for xZZ8Ef 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.jsonSandal Wedge Women's Mint Leather Beige Kayla Naot EtwqTt:

{
    "repositories": [
        {
            "type": "vcs",
            Clad Men's Brown Iron Inch Eight Boot LTT Rocky Work "url"Rocky LTT Work Brown Inch Boot Men's Eight Clad Iron : "https://github.com/you/monolog"
        Work Boot Iron Inch Rocky LTT Brown Men's Eight Clad }
    ],
    "require": {
        Boot Work Eight Rocky LTT Brown Clad Iron Men's Inch "symfony/monolog-bundle": "2.0"Rocky Boot Brown Inch LTT Work Men's Clad Iron Eight ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Brown Iron LTT Boot Eight Work Inch Clad Rocky Men's }

That will fetch the dev-bugfix version of Rocky LTT Inch Iron Work Men's Clad Brown Boot Eight 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.
