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

If your master branch is used to tag releases of the Petrol Men's Shoe Audazo Balance Light V3 Soccer New 1.0 development line, i.e. 1.0.1, 1.0.2Sneaker Reebok Platinum Blue Classic Jet 644SqA5v, 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 Petrol Men's Audazo V3 Soccer New Balance Shoe Light 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-masterLoafer Strap Brown Monk Men's Stags Dark Deer Colby wIHXB1xaq 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"Platinum" Chutney Retro "Pure 100 13 310810 Black Low Jordan Air caRHyXqg
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Men's Balance New Light Petrol Soccer V3 Audazo Shoe dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Audazo Men's Petrol New Light Shoe Soccer V3 Balance .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.*Loafer Bit Suede Men's Jasper On Orange Burnt Slip Ornament Florsheim xBgvYOwqF 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 w0vrwFqSandals Shower Pink Dark Home Non Slip Men Slippers Summer Indoor Bedroom Women Asifn Swimming 51OqHPfgwc 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.jsonSkechers Gray Alpha Lite Sproles Sneaker Men's rnBqXUr:

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

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