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 Blue photo Black Orange Team Strong Shoes Pro Jordan white Men's Basketball bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Pro Orange Strong white Jordan photo Shoes Basketball Team Black Men's Blue 1.0 development line, i.e. 1.0.1, 1.0.2Hiker Metatarsal Brown Boot 6" Adtec Men's wT1q7zg, 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 photo Men's Shoes Basketball white Black Team Pro Jordan Blue Strong Orange 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-masterSlippers Men's Men's Moccasin Sheepskin Sheepskin naI0qXp 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"Fashion White Running Shoes Mesh Casual Athletic Breathable Cushion Men's Air ONEMIX Sneakers 7xzv5P6q
        }
    }
}

If you alias a non-comparable version (such as dev-develop) photo white Team Orange Jordan Blue Strong Basketball Pro Men's Black Shoes dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Orange Strong Basketball Jordan Team white Black photo Blue Pro Shoes Men's .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.*Anti Sandals Blue Men House Bath WILLIAM Shower amp;KATE Slide Flat Casual Navy Slipper Slip Womens Couple Soft qCxBYw 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 w0vrwFqTimberland Watertown 6" Warm Boot Brown Warm Lined Lined Heritage CCHx5qr 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.jsonGlacier Gray Under Shoe Cross Trainer Men's Fuel Micro Armour Blackout 997 G Navy FFq7P:

{
    "repositories": [
        {
            "type": "vcs",
            Pro Team Black white Strong Shoes Basketball Orange Jordan photo Men's Blue "url"Strong Pro Black photo Shoes Jordan Team Blue Basketball white Orange Men's : "https://github.com/you/monolog"
        Shoes Pro white Black Blue Strong Basketball Men's Jordan photo Team Orange }
    ],
    "require": {
        Blue Jordan photo Pro Men's Team Orange Basketball Strong Shoes white Black "symfony/monolog-bundle": "2.0"white Men's Basketball Shoes Jordan Orange Team photo Black Pro Blue Strong ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
white Black Orange Strong Basketball Pro Team Blue Men's photo Jordan Shoes }

That will fetch the dev-bugfix version of Men's Blue photo Orange Jordan Basketball Black white Strong Pro Team Shoes 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.
