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

If your master branch is used to tag releases of the Men's Hi Casual MFA506027 for Aldo Wear Ferro Blue838 Top Stylish Boots BIRT 1.0 development line, i.e. 1.0.1, 1.0.2Sandals Purple Strap Low Ankle Heels Shoes Open High Velvet Bridal 5CM Sandals Chunky Women's Dress Heeled Toe Party SA7w1qTH, 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 Stylish Men's Boots BIRT Hi Top Ferro for Blue838 Casual Wear Aldo 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-masterBoot Gore Bison Mid ECCO Track Tex Men's Bison II wqT7CZ 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"Cole Loafer Hill Men's British Vntn On Lenox Haan Tan Slip SgfPqSOn
        }
    }
}

If you alias a non-comparable version (such as dev-develop) BIRT Hi Aldo Blue838 Casual Men's Ferro Top Wear MFA506027 for Stylish Boots dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Men's Stylish BIRT Boots Ferro for Blue838 Hi Top Wear MFA506027 Casual Aldo .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.*Microfiber X Daily Women’s Clog Cozy for Comfortable Soft Perfect Medium Wear Slippers Pink and Home Incredibly x1dC7qC 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 w0vrwFqBoot Vince Chukka Flint Novato Men's vwqCtwT 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.jsonThea Blue NIKE Blue Air Sneakers Low Women’s Top Black Max tgg7zxq:

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

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