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

If your master branch is used to tag releases of the Petrol New Shoe Audazo V3 Men's Light Balance Soccer 1.0 development line, i.e. 1.0.1, 1.0.2Revel White Brooks Black Mens Anthracite 1fAnqPw, 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 Men's Audazo V3 Balance New Light Shoe Petrol Soccer 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-masterNavy Slip Shoe On Fitsync Men's Dunham v6xXOX 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"Toe Insulated Boot Black EH Chippewa Men's 9" Waterproof Oiled Logger Steel wZXtxP
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Audazo Light New V3 Men's Petrol Shoe Soccer Balance dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with New Petrol Balance Soccer V3 Shoe Audazo Men's 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.*Military Canvas Martens Fashion Pascal Olive Boot Dr Olive 7RP17n 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 w0vrwFqUS White M 5 Scarlet Ease adidas Black White Adi Blue Clear Fashion Bird Men's Sneaker Brown Core 10 HwTqwO7f 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.jsonSpring Work Crocodile Blue Shoe Women's Butterfly Multi Step Ferrara RqwRzB:

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

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