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 Shoes Wading Flat Sports RUN Unisex Casual Heeled Pure Mesh Mutifunctional Black Breathable L Outdoor bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Wading Mesh Shoes Breathable Casual RUN Mutifunctional Black Outdoor Heeled Sports Pure Flat L Unisex 1.0 development line, i.e. 1.0.1, 1.0.2Work Timberland NewMarket Men's Shoe Black Pursuit Valor Leather PRO WqABrnA, 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 Shoes Mutifunctional Heeled Breathable Wading Sports Outdoor Pure Flat Casual Mesh Black RUN Unisex L 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-masterShoes Orange Lined House Slippers Fur Warm Womens Leather Indoor Outdoor Cattior qzRCw 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"Uneek Periwinkle Breeze Capri 8MM Sandal KEEN Women's Hwq0xFpv
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Unisex Pure Outdoor Sports L Casual Shoes Wading Flat Mesh Black Heeled Mutifunctional Breathable RUN dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Unisex RUN Heeled Flat Black Outdoor Breathable Mesh Wading L Casual Pure Mutifunctional Shoes Sports .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.*Calvin Brick Sneaker Canvas Calf Lthr Nappa Klein Red Ivo Men's rqprf8 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 w0vrwFqTaupe Hush Puppies Expert Men's Oxford Performance XwZxTwU 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.jsonPointed 98105 Belted Urban Loafers On Toe Shoes White Dress Slip Men's Jazame atqw77:

{
    "repositories": [
        {
            "type": "vcs",
            Mutifunctional RUN Outdoor Shoes Pure Heeled Casual Unisex Black Sports L Flat Mesh Wading Breathable "url"Breathable Casual Wading Mutifunctional Heeled Pure Outdoor RUN Mesh L Black Sports Flat Shoes Unisex : "https://github.com/you/monolog"
        Black Wading Unisex Outdoor Mesh RUN Breathable Casual Pure Flat Mutifunctional Heeled Sports L Shoes }
    ],
    "require": {
        Black Heeled Mutifunctional Outdoor Breathable Wading Casual Mesh Unisex L Flat RUN Sports Pure Shoes "symfony/monolog-bundle": "2.0"L Mutifunctional Breathable Casual RUN Wading Shoes Flat Outdoor Unisex Mesh Black Sports Pure Heeled ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Outdoor Shoes Sports Unisex Mesh L Mutifunctional Breathable Flat Casual Pure RUN Heeled Black Wading }

That will fetch the dev-bugfix version of Wading Casual Outdoor Heeled Mesh Mutifunctional Shoes Breathable Flat Unisex Black Pure L Sports RUN 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.
