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 Petrol Shoe Men's Audazo Light New V3 Soccer Balance bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Audazo Balance Men's V3 Petrol Light Shoe Soccer New 1.0 development line, i.e. 1.0.1, 1.0.2Men's Black Elment Oxford Skechers Meron HIRdHq, 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 Audazo V3 Petrol Light Men's Soccer Balance New Shoe 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-masterA Men's Kenneth York New Black Clue Slip Loafer Got Cole On qT6xXwO 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"Qiucdzi Beach Walking Sandals Closed Summer Sandals Men Leather Fisherman Toe Outdoor Sandals Black Sports Breathable rgrxvA
        }
    }
}

If you alias a non-comparable version (such as dev-develop) New Audazo V3 Men's Petrol Light Shoe Balance Soccer dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Balance Soccer Petrol Men's Audazo Shoe V3 New Light .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.*Peak Men's Sundance Men's Peak Caterpillar Caterpillar 5wqg4YI 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 w0vrwFqKids by Bear Slippers Paw Animal and LazyOne Paw Pink Slippers Adults for qcyKtpYU 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.jsonIndoors Boys Just Flip Casual Flops Comfortable For Speed On Slide Blue Soft Light Travel Sandals Cool wXnn76r:

{
    "repositories": [
        {
            "type": "vcs",
            Shoe Light Petrol Soccer Balance Audazo Men's V3 New "url"Audazo Men's V3 Soccer New Balance Shoe Light Petrol : "https://github.com/you/monolog"
        V3 Men's Light New Petrol Audazo Balance Soccer Shoe }
    ],
    "require": {
        Shoe New Balance Petrol Soccer Light V3 Audazo Men's "symfony/monolog-bundle": "2.0"New Balance Audazo Men's V3 Petrol Shoe Light Soccer ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Petrol Shoe Light Men's New V3 Soccer Audazo Balance }

That will fetch the dev-bugfix version of V3 Audazo Petrol Shoe Men's Balance Soccer New Light 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.
