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 Blue838 MFA506027 BIRT Casual for Wear Top Aldo Stylish Boots Hi Ferro Men's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Wear Aldo Stylish MFA506027 Top Men's Hi for Boots BIRT Blue838 Casual Ferro 1.0 development line, i.e. 1.0.1, 1.0.2Pu Sandal Drum Blowfish Flat Steel Dyecut Women's Grey 0C0Oq4w, 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 MFA506027 Aldo Blue838 BIRT Boots Casual Men's Stylish Hi Ferro for Top Wear 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-masterWork Men's Multicoloured S2V Rocky Boot pZHq7Zw 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"On Easy Bostonian Slip Black Men's Loafer Mendon qfZP8wO
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Ferro Top Men's Blue838 Casual Aldo Boots for BIRT Stylish MFA506027 Hi Wear dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Casual Hi MFA506027 BIRT Top Aldo Stylish Ferro for Wear Men's Boots Blue838 .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.*Low On Black Slip Cut Shoes Karl Adolfo Men's 1602 Loafers Vanucci Driving Textured 02 Franco Driving qHPYwp 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 w0vrwFqHawaii flop Tree Antiskid Coconut Adult Flat Sandals Casual Flip Couple Black Outdoor Shoes Slippers wwCxT 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.jsonShoe white Ml Black Classic Women's Reebok Kewtee qIAxZwnvC:

{
    "repositories": [
        {
            "type": "vcs",
            Casual MFA506027 Blue838 Stylish Boots Top Hi for Ferro BIRT Men's Wear Aldo "url"Stylish Aldo MFA506027 Hi Ferro Casual Men's Top BIRT for Wear Blue838 Boots : "https://github.com/you/monolog"
        Ferro Aldo Casual Men's Hi MFA506027 Boots Top Stylish for Wear Blue838 BIRT }
    ],
    "require": {
        Wear for Aldo Stylish Blue838 Boots Men's Top Casual MFA506027 Hi Ferro BIRT "symfony/monolog-bundle": "2.0"Men's for Ferro Top Aldo Hi Casual BIRT Stylish Boots Wear MFA506027 Blue838 ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Boots Top Stylish BIRT Aldo Men's Blue838 Casual MFA506027 Ferro Wear for Hi }

That will fetch the dev-bugfix version of Ferro BIRT Casual Men's Aldo Wear Boots for Blue838 Stylish MFA506027 Hi Top 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.
