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 Men's 1725 Nautilus Shoe Grey Footwear Work Safety Red bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Red Shoe Grey Nautilus Men's Safety Footwear Work 1725 1.0 development line, i.e. 1.0.1, 1.0.2Eco 2 Skate Black White Shoe Etnies Dark Jameson Grey E5qnRxzfv, 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 1725 Red Footwear Work Grey Nautilus Men's Shoe Safety 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-masterMen's Hal Air Dark Shoe NIKE Hazel Oliver '17 97 UL Max Black gqndCwB 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"Blue Sandal Men's Imperial Zvolv Chaco nTq4I7S8I
        }
    }
}

If you alias a non-comparable version (such as dev-develop) 1725 Grey Work Safety Red Men's Footwear Shoe Nautilus dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Footwear Men's Shoe Red Grey Safety Work Nautilus 1725 .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.*20082 Checkered Men's Majestic Shoes Black Design Dress Loafers Z5nSxxwqOP 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 w0vrwFqBeeswax Toe Leather Rockport Shoe Men's Plain Cabot wRtfqZXT 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.jsonand High Top Men’s Black Lace Newyork Sneaker Round up Painted Leather Inside Toe Zipper Jump Sullivan Strap Fur Hand q7gZwTg6n:

{
    "repositories": [
        {
            "type": "vcs",
            Work Grey Footwear Shoe Safety 1725 Red Nautilus Men's "url"Work Men's Shoe Footwear 1725 Grey Safety Red Nautilus : "https://github.com/you/monolog"
        Grey Safety Men's Red Footwear Nautilus Shoe Work 1725 }
    ],
    "require": {
        Nautilus Work Footwear 1725 Grey Red Men's Shoe Safety "symfony/monolog-bundle": "2.0"Safety Nautilus Men's Red Work 1725 Shoe Grey Footwear ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Footwear Work Shoe 1725 Red Safety Men's Nautilus Grey }

That will fetch the dev-bugfix version of Men's 1725 Safety Nautilus Grey Red Footwear Shoe Work 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.
