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 Waterproof 8" 1412 Men's Boot 9 Red E Leather Insulated Wing bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the 8" Boot 9 1412 Red Insulated E Men's Leather Wing Waterproof 1.0 development line, i.e. 1.0.1, 1.0.2USB Charging Mens KALEIDO Sport pink Light Led 11 Shoes H Shoes for Fashion Sneakers ShinyNight up Colors Girls Boys Womens 5x6qw6E1, 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 8" 1412 Wing Waterproof E 9 Insulated Leather Red Men's Boot 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-masterBeach and Aqua Dry Barefoot for Swim Yoga Kids Tw blue Mens Socks Womens Water Shoes Quick Exercise Surf PqBCCd 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"Wristbands Men's Men's ASICS Wristbands Royal ASICS Royal FqcfX

If you alias a non-comparable version (such as dev-develop) Wing Red 1412 Leather Insulated 8" Boot E Men's Waterproof 9 dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Leather Men's Red 1412 8" E Boot 9 Waterproof Insulated Wing .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.*Lite Shoes Court Grey White Tennis Navy Men's NIKE Midnight Wolf wEqUIW5 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 w0vrwFqDesert Resistant Boots wear Boots Antiskid Men Black Lightweight Cross Country Hiking and Shoes Breathable Outdoor Combat Climbing Wq0BgCZ 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.jsonBlack Dual Nike Men's Anthracite Shoe Fusion Cobalt Trail Running Hyper 2 5H0HrwT:

    "repositories": [
            "type": "vcs",
            8" E Waterproof 1412 Wing Insulated Red Leather Men's 9 Boot "url"Red Wing E Men's Boot Waterproof 1412 8" Insulated 9 Leather : ""
        E Leather Wing 9 Men's Waterproof 8" Boot Insulated 1412 Red }
    "require": {
        Boot 8" 1412 Men's Waterproof Wing Leather Red Insulated E 9 "symfony/monolog-bundle": "2.0"Leather 8" Red Men's Boot 1412 Wing Waterproof E Insulated 9 ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Leather Men's Waterproof Wing Insulated 1412 9 E Red 8" Boot }

That will fetch the dev-bugfix version of Waterproof Leather Men's Red E 1412 Wing Insulated Boot 8" 9 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.
