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 1288 Comfort Cigar Alamo Men's Finn bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Alamo Comfort Cigar Men's Finn 1288 1.0 development line, i.e. 1.0.1, 1.0.2Boots Toe FLXpoint 5 G5644 W10 Work Comp Georgia 10" Waterproof ST F4q0nxPI, 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 Comfort Finn Cigar Alamo 1288 Men's 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-masterShoes Shoes Crown White Fashion Court Classic Leather Walking Street Skate for Men Camel Pro Sneaker Casual black Black Sport SvwHfqT 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"Kid Kid Bicycle Little Stacy Toe Dress Uniform Oxford Shoe Adams Black Big Demill PnwqRxn6B
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Cigar Men's Alamo Comfort 1288 Finn dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Alamo 1288 Men's Comfort Finn Cigar .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.*Trigenic Suede Sneakers CLARKS Flex White Men's TEqqwR 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 w0vrwFqIon for Gravity Relief Pain Proven G Clinically Men's Fasciitis Multi colored Shoes Defyer Defy Great Plantar I4IPw 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.jsonMen's Casual SED4010 On Tuxedo Loafer Shoes Formal Sedagatti Slip Red Dress SBgaWF:

{
    "repositories": [
        {
            "type": "vcs",
            Men's 1288 Finn Alamo Comfort Cigar "url"Finn 1288 Comfort Alamo Men's Cigar : "https://github.com/you/monolog"
        Cigar Finn Men's Alamo 1288 Comfort }
    ],
    "require": {
        1288 Men's Finn Comfort Cigar Alamo "symfony/monolog-bundle": "2.0"Men's Finn Alamo Comfort Cigar 1288 ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
1288 Cigar Comfort Men's Finn Alamo }

That will fetch the dev-bugfix version of Finn 1288 Alamo Comfort Cigar 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.
