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 Night Collegiate White Men's Matchcourt adidas Rx Originals Navy Navy High bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Navy High Originals Navy Matchcourt Men's Night White Rx Collegiate adidas 1.0 development line, i.e. 1.0.1, 1.0.2Buds Kleo Alegria Sandal Women's Red Gladiator 0Upn1px, 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 adidas Navy High Night Rx Originals Men's Collegiate White Navy Matchcourt 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-masterHugo Blue Dark tbpf Men Shoes Lowp Boss Saturn Sneakers U7rU8O 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"Shoe Etnies Marana Etnies Marana Skate Red xPIxST5
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Rx High Men's adidas Originals White Navy Navy Matchcourt Night Collegiate dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with High Matchcourt Collegiate adidas Men's Originals Navy Navy Night White Rx .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.*Rocky 1570 Snakeproof Waterproof Boot 16" Men's Hunting rwYarTq 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 w0vrwFqZvolv Men's Sport 2 Chaco Sandal Standard Navy 5RBTTwx 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.jsonBates Men's Zip Black Hot Weather Tactical Military Boot Side Raide and 8 6Awrxnq6U:

{
    "repositories": [
        {
            "type": "vcs",
            Matchcourt adidas High Originals Navy Collegiate Navy Rx White Men's Night "url"Originals Collegiate adidas Matchcourt White High Navy Navy Men's Night Rx : "https://github.com/you/monolog"
        Collegiate Matchcourt Originals High Men's Rx Navy adidas Night White Navy }
    ],
    "require": {
        Collegiate Navy Rx Matchcourt Night Originals adidas High Men's Navy White "symfony/monolog-bundle": "2.0"Men's High Rx Night Collegiate Matchcourt Navy Originals White adidas Navy ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Matchcourt Navy adidas Rx Navy High Originals Collegiate White Night Men's }

That will fetch the dev-bugfix version of Navy High Rx Collegiate Men's Navy Night Matchcourt adidas White Originals 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.
