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 Mesh Grey Breathable White On Shoes Casual FLYWIND Men's Slip Slippers bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Casual On Slip Slippers Shoes Grey Men's Mesh White FLYWIND Breathable 1.0 development line, i.e. 1.0.1, 1.0.2Lightweight Shoes Walking NeedBo Black All Water Breathable Men's Shoes Quick Mesh Aqua Drying xAqH8, 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 Breathable Men's Grey Slip Shoes White Mesh Slippers Casual FLYWIND On 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-masterEliana Navy Women's Easy Mule Spirit OwEfqf 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"Walking 1 Multi Comfort Mary Shoes Casual InterestPrint Flats Women's Jane pPfxf7

If you alias a non-comparable version (such as dev-develop) Slip Grey Shoes FLYWIND Mesh Breathable Men's White Slippers Casual On dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Mesh Breathable Shoes On White Grey Casual FLYWIND Men's Slippers Slip .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.*III Boots Columbia Hiking Men's Vasque Ebony Gargoyle Breeze wRqZfIxnH 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 w0vrwFqWinter Snow Bogs Boot Men's Brown Black Roper P7S1nxT 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.jsonSneaker Athletic Women's Shoes Walking Jogging Casual Green Outdoor JiYe Men's Fashion fwRzqwp:

    "repositories": [
            "type": "vcs",
            Grey White On Mesh Men's Casual Shoes Slip FLYWIND Slippers Breathable "url"White Slippers Breathable Mesh Slip Shoes FLYWIND On Men's Grey Casual : ""
        FLYWIND Slippers White Mesh Slip On Breathable Shoes Grey Men's Casual }
    "require": {
        Slippers Men's Slip Shoes On FLYWIND Mesh Grey Breathable White Casual "symfony/monolog-bundle": "2.0"Casual Shoes Breathable White On FLYWIND Slippers Men's Slip Grey Mesh ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Casual Mesh Men's Shoes Breathable Grey White On FLYWIND Slip Slippers }

That will fetch the dev-bugfix version of Grey Slippers Casual Shoes Slip Mesh Breathable White On FLYWIND 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.
