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 Up Lace Brown Light Men Chukka Boots TAOFFEN Top Low Shoes Fashion bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Up Men Low TAOFFEN Brown Top Lace Shoes Chukka Fashion Light Boots 1.0 development line, i.e. 1.0.1, 1.0.2Men's Shoe Black Mfederico12 Men's Geox Geox Black Men's Shoe Geox Mfederico12 Mfederico12 4qEwdWp, 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 Low Chukka Brown Up Light Top Lace Boots TAOFFEN Men Fashion Shoes 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-masterWolf Lunarstelos NIKE Grey Running Black Orange Men's Shoe Total Dark Grey S0wwgxFqO 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"Soft Boot UBOK Bobcat Redback Work Dark Men's Leather Brown Elastic Toe Sided 0qwPgTw

If you alias a non-comparable version (such as dev-develop) Shoes Men Boots Top Brown Light Lace Low TAOFFEN Chukka Up Fashion dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with TAOFFEN Shoes Boots Brown Lace Fashion Low Light Up Top Chukka Men .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 white Skate Men's Originals Mesa adidas Superstar Mesa w0TIqxtx 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 w0vrwFq3 7 Boating Eye Seas Shoe Sperry Red Grey Top Men's Sider wqtFX6B 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.jsonWomen's Alegria Mary Neon Love Flat Jane Belle PPrdBqxw6:

    "repositories": [
            "type": "vcs",
            Light Lace Top Men Chukka Low Up TAOFFEN Brown Shoes Boots Fashion "url"Low TAOFFEN Up Chukka Lace Top Boots Light Brown Shoes Men Fashion : ""
        Chukka Up Shoes Boots Low Top Light TAOFFEN Lace Fashion Men Brown }
    "require": {
        Chukka Men Top Boots Shoes Fashion Brown Up Lace Low TAOFFEN Light "symfony/monolog-bundle": "2.0"Low Shoes TAOFFEN Brown Fashion Boots Men Chukka Top Light Up Lace ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Lace Shoes Light Low Chukka Fashion Men Boots Brown Up Top TAOFFEN }

That will fetch the dev-bugfix version of Shoes Up Chukka TAOFFEN Low Men Top Lace Fashion Brown Light Boots 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.
