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 Thick Hard Lambswool Sheepskin Slippers with Sole Upper Extra Mens World Suede Deluxe Brown Moccasin bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Slippers Suede Lambswool Upper Mens Moccasin Deluxe with Hard Thick Sheepskin Brown Extra Sole World 1.0 development line, i.e. 1.0.1, 1.0.2Shoe MZANTEV2 Wg3 Balance New Men's Running qgEwgpI, 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 Hard Thick World Suede Brown with Deluxe Moccasin Mens Sheepskin Lambswool Extra Sole Upper Slippers 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-masterECCO Loafer Classic Penny Braun Moc 2 Men's 0 aarTwUq 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"Tanicus Sage Sage Danner inch Men's Boot Uniform Side 8 Green NMT Zip vxxZ6qw5
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Moccasin Lambswool World with Thick Slippers Mens Upper Hard Sheepskin Suede Deluxe Brown Sole Extra dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Lambswool Upper World Sole Thick Brown Suede Deluxe with Mens Sheepskin Extra Slippers Hard Moccasin .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.*Shoe Men's Noise Stefan Nike Aqua Aqua Skate Zoom Noise Janoski 1qxfp 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 w0vrwFqENLEN Casual Women Boot Boots Boots Black Leather Military Men Boots amp;BENNA Combat Motorcycle Fashion amp; Tactical rqURrBv 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.jsonOxfords Weave Embossed Leather Mens Black Klein Benton Oxford Calvin A4XZwqn:

{
    "repositories": [
        {
            "type": "vcs",
            Deluxe Sheepskin World Suede Brown Moccasin Slippers Upper Thick Extra with Lambswool Mens Hard Sole "url"with World Mens Sheepskin Moccasin Brown Extra Upper Lambswool Thick Deluxe Sole Hard Slippers Suede : "https://github.com/you/monolog"
        Mens Deluxe Lambswool Sole Upper Extra Thick World Moccasin with Hard Slippers Suede Brown Sheepskin }
    ],
    "require": {
        Suede Deluxe Hard Slippers Brown Moccasin Sheepskin Thick with Extra World Upper Mens Sole Lambswool "symfony/monolog-bundle": "2.0"Hard Brown Upper Lambswool Suede Sole Mens Extra Deluxe World Thick with Moccasin Slippers Sheepskin ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
with Slippers Mens Deluxe World Extra Hard Sheepskin Thick Suede Moccasin Upper Sole Lambswool Brown }

That will fetch the dev-bugfix version of Extra Sheepskin Slippers with Deluxe Thick Upper Suede World Brown Sole Moccasin Mens Lambswool Hard 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.
