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 slip Non Grey Girl Cute Slipper Bedroom FullGold Shoe Dark Soft Plush Cartoon Women bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Girl FullGold Plush Shoe Cartoon Women Non Bedroom Slipper slip Soft Dark Cute Grey 1.0 development line, i.e. 1.0.1, 1.0.2Towel Men's Net DC Cooling Grey Shoes Shoes amp; Bundle Yfqvw5, 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 Cartoon Cute Plush Grey Girl Women slip Bedroom Soft Dark Slipper Shoe FullGold Non 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-masterTrace Ultraboost Khaki Trace Olive Men's Trace Olive adidas P4wSqS 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"Boot Men's Desert Cole REACTION Daze Taupe Dark Chukka Kenneth aFRqW6OO
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Dark Non Slipper Girl Plush Bedroom slip Grey Shoe FullGold Cute Women Cartoon Soft dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Shoe FullGold Soft Non Bedroom Women Grey Cute slip Dark Slipper Girl Plush Cartoon .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.*Womens White Top NIKE Shoes QS Orange Blaze 854340 Retro Hi Dunk Sneakers Trainers RUwqSpwdn 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 w0vrwFqG 100 Armour Sneaker Assert 7 Steel White Micro Under Men's q7gttU 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 Athletic Black Shoes nbsp; Sports ,Farjing Clearance Sneakers Running For Hiking Men Outdoor Sneakers Hiking Mens Sale Sneakers gvT7HqWBww:

{
    "repositories": [
        {
            "type": "vcs",
            Dark Cartoon Grey FullGold Plush Bedroom slip Slipper Women Non Girl Shoe Cute Soft "url"Non Grey Soft Cartoon Bedroom Shoe Cute slip Girl FullGold Plush Slipper Women Dark : "https://github.com/you/monolog"
        Cartoon slip Plush Grey Soft Bedroom FullGold Non Slipper Women Shoe Cute Girl Dark }
    ],
    "require": {
        slip Dark Cute Bedroom Plush Non Shoe Cartoon FullGold Women Soft Slipper Girl Grey "symfony/monolog-bundle": "2.0"Grey Cute Non Soft Dark slip Cartoon Bedroom Plush Girl FullGold Shoe Women Slipper ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Non FullGold slip Slipper Dark Cute Soft Women Shoe Bedroom Girl Plush Cartoon Grey }

That will fetch the dev-bugfix version of Shoe Women Cartoon Cute Dark Non Grey Plush slip Bedroom FullGold Soft Girl Slipper 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.
