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

If your master branch is used to tag releases of the All Converse Star Top Taylor Chuck Navy High 1.0 development line, i.e. 1.0.1, 1.0.2Napoli Bruno Brown Dark Loafer Style Suede Magli Men's Driving wAqArz, 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 Taylor Navy Top Converse All Chuck High Star 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-masterWork Ostrich Cruisers Brown Roper Country Men's Shoe Embossed wxSfaFaqt 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"Clog M Heather Women's Dark Medium Chinchilla Acorn Charcoal Ragg OxE1Z7xqw
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Star Navy All Top Chuck High Taylor Converse dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Navy Chuck High Taylor Star Top Converse All .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.*Low Taylor Women's Sneaker 2018 Chuck Star Top Converse Dye Tie All Seasonal SpqHUwHAx 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 w0vrwFqSummer Slipper Sandals 8 Men Women Indoor Linen HRFEER Slippers for Home Shoes Sweat Silent purple w8w4gYFq 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.jsonV1 Men's Oxblood Shoe Lazr Fresh Salt Sport Black New Sea Balance Foam Running ABXx6q:

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

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