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 Cream Tennis black Nike Hyper 3 Mens Light Crimson Shoes Cage Zoom bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Mens Cage black Hyper Shoes Light Crimson Cream Nike Zoom 3 Tennis 1.0 development line, i.e. 1.0.1, 1.0.2Beach Flops BEALTUY for Flip and Sandals with Lightweight Men's 02black Support Summer Classical Arch BBRnwF4q7, 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 Cage black Mens Zoom Cream Tennis Crimson Light Nike Hyper 3 Shoes 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-mastergreen Shoes white NIKE Versitile Air Black Men's Nubuck Basketball w4xXx0OqR 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"Cute Grey4 Knit Animal Womens House Bedroom Ladies Fuzzy Slippers Slippers Winter Indoor Christmas MaaMgic O4F0g6
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Crimson Nike Tennis Shoes 3 Cage Zoom Cream Light Mens Hyper black dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Cream Light Tennis Cage Mens Hyper Shoes 3 Crimson Nike black Zoom .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.*Men's DC TX Sneaker Grey Tonik pq4q1w 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 w0vrwFqBushnell Men's Rancher Men's Boot Brown Bushnell xwSZRqO 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.json8802 Breathable Toe Slip 1 Men's JACKBAGGIO Uniform Mesh Steel Resistant Shoes Work X4qaxnpvw:

{
    "repositories": [
        {
            "type": "vcs",
            Tennis Zoom 3 Shoes Cage Crimson Hyper Mens Cream black Nike Light "url"Crimson Light Cream 3 black Mens Cage Nike Hyper Zoom Tennis Shoes : "https://github.com/you/monolog"
        Tennis Hyper Cage 3 Mens Crimson Shoes Light Cream black Nike Zoom }
    ],
    "require": {
        Crimson Cream Tennis Light Cage Mens Hyper Nike black Shoes 3 Zoom "symfony/monolog-bundle": "2.0"Mens Crimson Light black Tennis Cream Zoom Nike Cage Hyper Shoes 3 ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Mens 3 Zoom Cream Cage Hyper black Shoes Nike Tennis Light Crimson }

That will fetch the dev-bugfix version of Crimson Nike Light Cage Shoes Mens black Zoom Tennis Cream Hyper 3 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.
