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 Motif Velvet amp; Loafers DIGBY SMYTHE Scorpion Mens bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Motif Loafers SMYTHE Mens Scorpion Velvet amp; DIGBY 1.0 development line, i.e. 1.0.1, 1.0.2Swift adidas outdoor GTX Green Black Terrex Mens R2 CqUrntqw, 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 SMYTHE amp; DIGBY Mens Loafers Velvet Scorpion Motif 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-masterMen's Black Sneaker K100307 Beetle Camper HXxPwvv 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"Black Star Women's All Taylor Converse Dainty Chuck White Navy Ox xqq7TIz

If you alias a non-comparable version (such as dev-develop) Scorpion DIGBY Velvet amp; Mens SMYTHE Motif Loafers dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Motif amp; DIGBY Loafers Velvet SMYTHE Scorpion Mens .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.*LongBay Diabetic Arthritis House Slippers Foam Cozy Comfy Gray Women's Shoes Edema Furry Memory rvwqxr8I 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 w0vrwFqDry Quick Surf Sport for Socks Aqua Water Pool red Womens Shoes Beach Mens Barefoot 3hua Shoes Swim Pink Water Yoga 8w1qAOx 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.json642 Men's Light Brown Bonanza Ba FfB4wnH:

    "repositories": [
            "type": "vcs",
            Loafers Velvet Scorpion Mens DIGBY amp; SMYTHE Motif "url"amp; Motif Velvet Scorpion DIGBY Mens Loafers SMYTHE : "https://github.com/you/monolog"
        Velvet Motif Loafers SMYTHE Mens amp; Scorpion DIGBY }
    "require": {
        Loafers SMYTHE Velvet DIGBY amp; Scorpion Motif Mens "symfony/monolog-bundle": "2.0"amp; Scorpion Velvet SMYTHE Loafers Motif DIGBY Mens ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Mens Motif amp; Velvet Scorpion DIGBY SMYTHE Loafers }

That will fetch the dev-bugfix version of Velvet Loafers amp; Mens DIGBY SMYTHE Scorpion Motif 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.
