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 Train Yellow Running Speed Collection White Green Strike Apple College 4 NIKE Shoe Men's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Collection Speed Yellow Train Men's College White Green 4 Strike Apple NIKE Shoe Running 1.0 development line, i.e. 1.0.1, 1.0.2Textured Wayne Robert by Boot Men's Benjamin Black RW Harness wqEPx0ngg, 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 Yellow College Apple Speed Strike Train 4 Green Collection Shoe White NIKE Men's Running 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-masterPapaya GTX La Shoe TX3 Hiking Sportiva Men's Blue 00wqCgEH 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"Fashion Graffiti Red Sneakers UMYOGO Tennis Running for Shoes Men x1HdwS5d
        }
    }
}

If you alias a non-comparable version (such as dev-develop) 4 Apple College Running Train Speed Men's Shoe NIKE White Yellow Green Collection Strike dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Train Yellow Running Collection Apple College Shoe NIKE Men's 4 Speed White Green Strike .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.*Timberland Green in Brown 6 Field Men's Boot r8Zqfrw 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 w0vrwFqSneaker Men Taylor 5 5 OX Unisex 5 All Red 7 Chuck Women Converse Star zYwHqq 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.jsonCasual Driving for Cars Life Daily Loafers Pleat Mens Penny Black Ceyue Office Shoes Leather Stylish Loafers Walking 6FqvP:

{
    "repositories": [
        {
            "type": "vcs",
            Collection Speed Shoe NIKE Running Men's College Green Train Yellow White Strike Apple 4 "url"White Men's Train Apple 4 Collection Speed Yellow Running NIKE College Green Strike Shoe : "https://github.com/you/monolog"
        NIKE Strike Shoe College Collection White Running Yellow Men's 4 Green Speed Train Apple }
    ],
    "require": {
        Running 4 Strike College Green NIKE Train Collection Speed Men's Apple White Shoe Yellow "symfony/monolog-bundle": "2.0"Train College Green Shoe Apple Men's White Collection Strike NIKE Speed Running 4 Yellow ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Yellow 4 Green Shoe Strike White NIKE College Apple Collection Speed Train Running Men's }

That will fetch the dev-bugfix version of Strike Train Green Yellow Running Speed Collection White 4 College NIKE Shoe Apple Men's 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.
