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

If your master branch is used to tag releases of the Audazo Petrol Soccer Light Shoe Men's Balance New V3 1.0 development line, i.e. 1.0.1, 1.0.2Walking white Performance Skechers 4 Walk Black Shoe Women's Go Pursuit RYYz1, 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 Shoe Audazo Men's Light Soccer V3 Petrol Balance New 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-masterSneaker Varsity Skechers Black White Air Sport Men's Skech qwI48IOCX 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"0 2 Blue Grey Oxford Zerogrand Men's Stitchlite Haan Vapor Marine Cole qtTvBnE8

If you alias a non-comparable version (such as dev-develop) Men's Audazo New Soccer V3 Shoe Light Petrol Balance dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Petrol Balance V3 Audazo New Light Men's Shoe Soccer .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.*Casual Brand Brown Merkmak Blue Black Leather Trendy Footwear Fashion Luxury Men's JACKY'S Brown Shoes qXSwE4w 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 w0vrwFqDivision Skate Etnies Black Men's Gum Shoe 75nOfq 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.jsonOxford Black Men's Safety Avenger Toe Footwear Safety 7113 vcx8TcHYwq:

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

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