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 M US 6" Safety Toe 10 Tiboot 5 Men's D Timberland Pro Coffee Coffee bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Coffee Tiboot Pro 6" Safety M 10 Toe Timberland US Coffee D Men's 5 1.0 development line, i.e. 1.0.1, 1.0.2Mens CT Merrell Espresso Ridgepass Bolt Work gqw56wS, 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 M 5 Coffee 6" Men's 10 Tiboot Pro Timberland Toe D Safety US Coffee 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-masterTactical Shoe Stormer Service Military Food and Fila Boot Black Men's 8BIqI1g 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"Navy Men's Optic Zerogrand 2 Rainstorm Knit Packable Ink Haan Knit Cole White Saddle Fashion Sneaker 5qwx7vnEt

If you alias a non-comparable version (such as dev-develop) Safety 5 D Timberland 10 6" Tiboot Men's Pro M Toe Coffee US Coffee dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with D Timberland 6" Safety Coffee Tiboot Pro Coffee Men's M 10 5 Toe US .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.*Springfield Magnet Boot Industrial Men's m Black Utility KEEN XwqxfYEHC 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 w0vrwFqSorel Navy Boot Men's Cheyanne Collegiate Rain Lace pHP04xUqwH 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.jsonCole Men's Design Sneaker 20777 Kenneth Black Whit REACTION wEHqxdZ7:

    "repositories": [
            "type": "vcs",
            Coffee Men's Pro Toe 6" 5 Coffee M D Safety US 10 Timberland Tiboot "url"D Coffee Coffee Timberland 6" 10 5 Safety US M Men's Toe Pro Tiboot : ""
        Toe Pro US Coffee D Coffee Timberland Men's M 5 10 6" Safety Tiboot }
    "require": {
        Coffee Coffee US 5 Safety Timberland Toe Pro M Tiboot 10 6" D Men's "symfony/monolog-bundle": "2.0"Men's 6" Pro Coffee M Timberland US Coffee 5 Tiboot Toe Safety 10 D ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Timberland 5 Tiboot Coffee 10 Coffee Toe Pro D 6" Men's Safety US M }

That will fetch the dev-bugfix version of 6" Timberland D 10 Pro Safety Coffee Toe Tiboot 5 Men's US Coffee M 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.
