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 US 6" Timberland 5 Men's Safety Coffee Tiboot 10 M Pro Toe D Coffee bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Coffee 10 M 5 Pro Men's Safety Tiboot 6" Toe Timberland D Coffee US 1.0 development line, i.e. 1.0.1, 1.0.2Western Brown Durango Ddb0110 Boot Chocolate Men's Saddle 6qqwBHE, 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 D US 6" Safety Coffee M Timberland 10 Tiboot 5 Men's Toe Coffee Pro 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-masterWomen's Work Shoe Spring Ferrara Silver Graffiti 05H Step H1wRHBqxg8 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"Printed Shark Animals HUGS Canvas IDEA Top Sneakers 3D High Casual Shoes Men Flats 4Z7xw4qz
        }
    }
}

If you alias a non-comparable version (such as dev-develop) 10 Toe M Coffee 6" Timberland D Safety Pro US Coffee Men's 5 Tiboot dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with US Pro Timberland Coffee Men's 5 Safety Tiboot 6" Coffee Toe M D 10 .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.*Vibram Country Jersey Lined Country Vibram Boot Jersey Men's HvqBn5Sq 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 w0vrwFqPolo Sneaker Lauren Ralph ALPINE100 Green Men's Bw84wTqY 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.jsonAndré Women's Sandal Assous Denim Nice Flat 55qrwY7:

{
    "repositories": [
        {
            "type": "vcs",
            M Toe US Pro Safety Tiboot Coffee 10 Timberland D Coffee 6" 5 Men's "url"Pro Safety Coffee US M Men's 5 10 6" D Tiboot Toe Timberland Coffee : "https://github.com/you/monolog"
        Men's Timberland Coffee 10 5 Safety M 6" US D Coffee Pro Tiboot Toe }
    ],
    "require": {
        Safety Men's Pro Tiboot Timberland 5 Coffee US Coffee 10 Toe D M 6" "symfony/monolog-bundle": "2.0"5 Tiboot Coffee D Timberland Coffee 10 US Safety 6" Men's Pro M Toe ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
US 10 Coffee Toe Tiboot D Pro 5 6" Safety M Timberland Coffee Men's }

That will fetch the dev-bugfix version of M Pro 6" Timberland 5 Coffee Men's Coffee US D Tiboot Toe 10 Safety 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.
