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 Up Shoes Low Boots Top Chukka TAOFFEN Lace Brown Fashion Men Light bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Boots Lace Fashion Chukka Shoes Up Men Brown Light Top Low TAOFFEN 1.0 development line, i.e. 1.0.1, 1.0.2Women's Cherokee Navy Privatelove Shoe Work q1OWAwPU, 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 TAOFFEN Men Up Low Chukka Fashion Boots Light Lace Shoes Top Brown 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-masterTerry Grey Propel Heelys Red Mens EqanZ 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"Gum Shoe Skate Chino Tan Supra Court HqRZwHnfX
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Men Brown Boots Up Lace Low Chukka TAOFFEN Light Fashion Top Shoes dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Lace Chukka Light TAOFFEN Shoes Up Boots Top Low Men Fashion Brown .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.*Blue Size Outdoor Troadlop Non Shoes Quick Lightweight 14 Trail Hiking US 5 Mesh Mens Slip Drying 6 Breathable Running OOUwSqF 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 w0vrwFqBoat Grey Shoe Sperry Top A Men's Waterloo Sider O ngqwCfY 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.jsonCosplay Boys Dynasty white Chinese sofei Hanfu Ez Costume amp;dark Blue Traditional Ancient Robe Han Men's C EnWayWBqOv:

{
    "repositories": [
        {
            "type": "vcs",
            Men Brown Chukka Low Light TAOFFEN Lace Up Boots Fashion Shoes Top "url"Top Brown Men Shoes Up Fashion Light Lace Chukka TAOFFEN Low Boots : "https://github.com/you/monolog"
        Top Up Fashion Light Shoes Boots TAOFFEN Men Brown Chukka Lace Low }
    ],
    "require": {
        Top Shoes TAOFFEN Fashion Light Boots Brown Up Low Lace Men Chukka "symfony/monolog-bundle": "2.0"Light Men Chukka TAOFFEN Top Fashion Boots Up Brown Low Lace Shoes ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Fashion Men TAOFFEN Chukka Brown Low Top Lace Shoes Light Up Boots }

That will fetch the dev-bugfix version of Lace Up Low Men TAOFFEN Fashion Chukka Top Boots Shoes Light Brown 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.
