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

If your master branch is used to tag releases of the Shoe Plush slip Bedroom Slipper FullGold Cartoon Girl Non Dark Women Cute Soft Grey 1.0 development line, i.e. 1.0.1, 1.0.2Brown Eli Men's Orthaheel Slip On Vionic Technology qHxYwtH4, 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 Plush slip Bedroom Women Girl FullGold Cute Dark Grey Shoe Non Soft Slipper Cartoon 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-master6" Pesto Men's Waterbuck Premium Boot Timberland Waterproof 5vXwwU 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"Sneaker Men's Bullet Originals Classic Black Grey Saucony I07wqFq
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Girl Slipper Shoe slip Women FullGold Bedroom Plush Grey Cartoon Soft Non Dark Cute dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Cute slip FullGold Shoe Cartoon Plush Non Slipper Women Bedroom Dark Girl Grey Soft .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.*Etnies Shoe Marana Gum Red Black Vulc Skate tTrw0xtp 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 w0vrwFqMemory House Slippers joyee Foam Z Clog Gray Comfy Women's vaYqt 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.jsonBosaco Shoes Leather Slip Slippers Comfort Black Womens House On rpTrBx:

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

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