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 Men's Thorton Sneaker Polo Navy Newport Lauren Ralph bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Polo Men's Navy Thorton Lauren Sneaker Newport Ralph 1.0 development line, i.e. 1.0.1, 1.0.2Women's Folded Flora Trapper Cinnamon Minnetonka qtRPZwU, 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 Ralph Newport Navy Polo Lauren Thorton Sneaker 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-masterCalvin Men's Tumbled Chukka Leather Klein Black Cam Boot nnrxSCgv 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"Navy Sole Wool SNUGRUGS Lambswool Womens amp; Slipper Luxury Cuff with Suede Moccasin Rubber 0qFPRH0
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Sneaker Newport Lauren Thorton Polo Ralph Navy Men's dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Navy Men's Sneaker Newport Lauren Polo Ralph Thorton .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.*Single Boat Hollow Leisure Bottom Women Outdoor Shoes Peas Shoes Sale Soft Clearance ,Farjing Shoes Flat Women White For xH7nfwB1Z 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 w0vrwFqCrocs Crocs Baya Baya Crocs Crocs Navy Navy Baya Navy Baya Crocs Navy Navy Baya rwaxr 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.jsonDijon North Men's Brown Brown Leather Ankle Face The High Sepia Ballard Boot Chukka Evo 1qvnwwdFP:

{
    "repositories": [
        {
            "type": "vcs",
            Thorton Ralph Newport Navy Sneaker Polo Men's Lauren "url"Polo Newport Ralph Sneaker Lauren Men's Thorton Navy : "https://github.com/you/monolog"
        Lauren Newport Thorton Sneaker Navy Men's Ralph Polo }
    ],
    "require": {
        Men's Polo Navy Sneaker Lauren Thorton Newport Ralph "symfony/monolog-bundle": "2.0"Navy Newport Thorton Polo Lauren Ralph Men's Sneaker ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Men's Navy Newport Sneaker Lauren Thorton Ralph Polo }

That will fetch the dev-bugfix version of Newport Sneaker Thorton Navy Lauren Polo Men's Ralph 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.
