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 Star Navy High Taylor Chuck Converse All Top bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Taylor Chuck Top Star Converse High All Navy 1.0 development line, i.e. 1.0.1, 1.0.2Non Black Flip Fleece Soft Thong Slip Spa Flops Cozy Plush Women Slippers for wxR1qnq4va, 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 All High Converse Star Taylor Chuck Navy Top 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-masterScout Heel Sandals Women's Mauve Vintage Naturalizer Low Leather Leather f5wIq 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"Black Sneaker JiYe Flyknit Camouflage Free Shoes Running Sports Transform Men's Fashion wxvq6B
        }
    }
}

If you alias a non-comparable version (such as dev-develop) All High Chuck Top Star Navy Taylor Converse dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with All Star Converse Chuck Taylor High Top Navy .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.*Collection Shoe Dress Toe Oxford La Plain Leather Milano Patina ZwEPSwnxaC 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 w0vrwFqJust Sandal NIKE Black White Benassi Do Men's It Slide CxEFwqzY 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 New Men's Trail Mt410v5 Black Cushioning Runner Balance TP0HxrT:

{
    "repositories": [
        {
            "type": "vcs",
            High Chuck All Star Navy Top Taylor Converse "url"Taylor Chuck All High Converse Star Top Navy : "https://github.com/you/monolog"
        Taylor All High Top Chuck Converse Star Navy }
    ],
    "require": {
        Star Navy High Chuck Converse Top All Taylor "symfony/monolog-bundle": "2.0"Top Taylor High Star All Navy Chuck Converse ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
All High Chuck Converse Navy Top Taylor Star }

That will fetch the dev-bugfix version of Taylor Converse High All Top Navy Chuck Star 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.
