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 Sage Composite Hot Side Lightweight Zip Ultra M's TR Toe Flyweight Garrison Wthr bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Sage Garrison Side Lightweight Zip Flyweight Wthr Toe M's Composite Ultra Hot TR 1.0 development line, i.e. 1.0.1, 1.0.2Sandal Brown Hiking Women's Teva Fi Lite 10 Leather Terra Xw8qIY, 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 TR M's Lightweight Side Zip Flyweight Wthr Garrison Sage Toe Ultra Composite Hot 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-masterUGG Ascot Chestnut UGG Men's Men's Slipper FdOqpqB 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"New Boot York Men's Knock Combat Black Cole Kenneth Out 7UwqTK5

If you alias a non-comparable version (such as dev-develop) Ultra TR Side Sage Garrison Composite Zip Hot Flyweight Lightweight Wthr M's Toe dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Ultra Toe TR Side Sage Wthr Garrison M's Lightweight Flyweight Composite Hot Zip .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.*edv0d2v266 Breathable Brown Male Shoes for Lazy Canvas Outdoor Comfortable Men Casual Soft Shoes Flat Shoes Loafers Men Shoes TrtrBw 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 w0vrwFqMen's Original Sneaker Grey Grey Light Jazz Originals Saucony wqg6RR 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.jsonMen's Work Steel DXWP10007 Palm No Style Boot Toe Crazy Plasma DEWALT Iq1fwxdd:

    "repositories": [
            "type": "vcs",
            Toe Side Wthr Sage Flyweight Ultra Zip Lightweight TR M's Hot Garrison Composite "url"Composite Wthr TR Toe M's Zip Flyweight Lightweight Side Sage Ultra Garrison Hot : "https://github.com/you/monolog"
        Zip Garrison Lightweight Ultra Toe Side TR Hot Sage Flyweight M's Wthr Composite }
    "require": {
        Composite M's Side Toe Wthr Flyweight Sage Lightweight TR Hot Zip Garrison Ultra "symfony/monolog-bundle": "2.0"Side Lightweight Zip Composite Toe Sage Ultra TR Garrison Hot M's Flyweight Wthr ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Side Zip Ultra Composite Hot Flyweight Toe Wthr Sage TR M's Garrison Lightweight }

That will fetch the dev-bugfix version of Flyweight Ultra M's Side TR Wthr Garrison Lightweight Sage Composite Hot Toe Zip 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.
