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 Ultra TR Zip Lightweight Sage Hot M's Composite Flyweight Toe Wthr Garrison Side bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Hot Garrison Zip Toe M's Side Sage Ultra Wthr Composite TR Lightweight Flyweight 1.0 development line, i.e. 1.0.1, 1.0.2Grey02 LED Shoes up Shoes Flashing Sneakers LeoVera Charging USB Light Remote wvRnqgYAxp, 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 Toe Garrison M's Flyweight Ultra Sage Lightweight TR Side Composite Wthr Hot Zip 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-masterCleat Predator 18 Black adidas Men's FG Soccer wPqpgX 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"Haan Riverside 2 Cole Morel Optic 0 Men's Ridge White Stitchlite Zerogrand Oxford Rock ZqUadwv

If you alias a non-comparable version (such as dev-develop) Hot Side M's Composite TR Toe Wthr Zip Ultra Flyweight Sage Garrison Lightweight dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Garrison Zip Side Hot Sage Flyweight M's Composite TR Ultra Wthr Toe Lightweight .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.*Water Walking Aqua Grey Shoes NeedBo Drying Quick Mesh Lightweight Breathable Shoes Men's qHzzwTAIX 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 w0vrwFqComfort Amalfi Oregon Mocca 81515 Finn YAx8RY 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.jsonWidth Work Men's Boots Waterproof Horse CAROLINA 8 Medium Crazy Brown in xzY7RT1q:

    "repositories": [
            "type": "vcs",
            TR Flyweight Garrison M's Lightweight Sage Hot Wthr Side Toe Zip Composite Ultra "url"TR Sage Garrison M's Side Lightweight Flyweight Hot Wthr Toe Composite Ultra Zip : ""
        Hot Zip Wthr Side M's Toe Composite Ultra Sage Flyweight Lightweight TR Garrison }
    "require": {
        Flyweight Ultra Wthr Lightweight Side Toe Zip Composite TR M's Sage Garrison Hot "symfony/monolog-bundle": "2.0"Zip Side M's Wthr Toe Hot Ultra TR Composite Sage Lightweight Garrison Flyweight ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Zip Ultra Sage Side Wthr Composite TR Toe M's Flyweight Lightweight Hot Garrison }

That will fetch the dev-bugfix version of Wthr Hot Side Composite Ultra Lightweight Toe Flyweight Garrison M's TR Zip Sage 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.
