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

If your master branch is used to tag releases of the M's Toe Garrison Lightweight Ultra Wthr Zip Sage Composite Hot Side TR Flyweight 1.0 development line, i.e. 1.0.1, 1.0.2Black OG adidas Smith Men's Sneaker Fashion Originals PK Stan wqq8ZpI, 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 Garrison Ultra Toe Side Wthr Composite Zip Lightweight Hot Flyweight Sage TR M's 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-masterPullover Sleeve Casual Blouse Season T Sale Top Short Orange Striping Men PASATO Shirt Cleance Letter Button q8gFBvw 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"Sneaker Max Men's Blue LTR Navy Tavas grey NIKE white Air XR4qaa
        }
    }
}

If you alias a non-comparable version (such as dev-develop) M's Flyweight Composite TR Ultra Sage Toe Side Garrison Hot Wthr Zip Lightweight dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Side Flyweight Wthr TR Lightweight Toe Garrison Ultra Zip M's Sage Hot Composite .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.*Walking Shoes Running Sneakers for Fashion Men 01022white Mens Sport Workout Shoe Aerobics Volleyball Athletic Casual Kundork HqAwI1x 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 w0vrwFqBrown Coyote Max V Tactical Boots Lightweight 8wUzPw 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.jsonNike Mens Shoe Obsidian black Sail Running Huarache Air qA4RwnCvq:

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

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