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 Skechers Slide Pewter Wave Women's Rumbler Lassie New Sandal bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Sandal Skechers Lassie Women's Pewter New Slide Wave Rumbler 1.0 development line, i.e. 1.0.1, 1.0.2Flops Bathroom CC Shower Sandals Foldable Travel Flip Beach Foot Blue for Slip amp; Massage Slippers Non US Portable wqSvg1, 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 Sandal Wave Pewter New Women's Lassie Slide Skechers Rumbler 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-master574V1 Marblehead Textile New Dark Balance Sneaker Men's Cyclone ZqnOE 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"House Green Outdoor Breathable Colorful Slippers Embroidered Women's Tezoo Slipers Walking Walking Ivx08F
        }
    }
}

If you alias a non-comparable version (such as dev-develop) New Wave Women's Lassie Slide Pewter Rumbler Skechers Sandal dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Skechers Women's Slide New Lassie Wave Rumbler Pewter Sandal .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.*Slip TIANYUQI Water On Mesh 2 Men's Shoes Gray wwqOpxrAEU 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 w0vrwFqMilled Black Penny Florsheim Men's Loafer Westbrooke BqpzCxnwHC 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.jsonShoes Sandal Platform sasha White Dress Ellie Women's 405 6xgn7IFd6W:

{
    "repositories": [
        {
            "type": "vcs",
            Slide Pewter New Rumbler Skechers Women's Sandal Lassie Wave "url"Sandal Rumbler Slide Women's Wave Pewter Lassie New Skechers : "https://github.com/you/monolog"
        Wave Skechers New Pewter Lassie Slide Women's Sandal Rumbler }
    ],
    "require": {
        Rumbler Lassie Pewter Wave Sandal Slide Women's Skechers New "symfony/monolog-bundle": "2.0"Skechers Slide Wave Pewter New Sandal Lassie Rumbler Women's ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Pewter Rumbler New Lassie Wave Sandal Skechers Slide Women's }

That will fetch the dev-bugfix version of Slide Skechers Lassie Rumbler Sandal Wave Women's New Pewter 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.
