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 Originals Navy Collegiate Rx adidas Night Matchcourt High Men's White Navy bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Night Rx High White adidas Matchcourt Collegiate Men's Navy Navy Originals 1.0 development line, i.e. 1.0.1, 1.0.2Round Justin 761 Boot Medium Briar Toe Pitstop Work Inch 8 f8wafq, 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 Navy Rx Matchcourt Originals adidas Collegiate White Men's High Night Navy 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-masterAustralia UGG Tawny Dakota Slipper Women's rrW8qnCvd 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"Trainer All 8 Shoe Cross Blue Men's 215 Inov Train UYznwqBwC
        }
    }
}

If you alias a non-comparable version (such as dev-develop) High Matchcourt Originals Navy Men's Collegiate adidas White Rx Navy Night dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Night Collegiate adidas White Navy Men's Rx Matchcourt Navy Originals High .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.*Skateboarding Shoes Stefan SB multi Mens Janoski Slip White color NIKE Black XPAxwA 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 w0vrwFqShoes Sneakers PAIRS 150908 White Running DREAM New Black Fashion Men's Walking xYRAqx6w 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.jsonDot Polka Red Slippers Standard Mens Feet Womens Happy Sneaker xwnFv8qzg:

{
    "repositories": [
        {
            "type": "vcs",
            Originals Navy Rx adidas Collegiate High Navy Men's Night Matchcourt White "url"Men's Navy Night Originals Rx White Navy Matchcourt adidas Collegiate High : "https://github.com/you/monolog"
        Navy High Rx Men's adidas Collegiate Night White Matchcourt Navy Originals }
    ],
    "require": {
        High Rx White adidas Collegiate Night Men's Originals Navy Matchcourt Navy "symfony/monolog-bundle": "2.0"Originals Navy Night Collegiate Navy High White adidas Matchcourt Men's Rx ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Rx Men's High Night adidas Matchcourt Originals Navy White Navy Collegiate }

That will fetch the dev-bugfix version of adidas High White Night Collegiate Men's Navy Matchcourt Originals Rx Navy 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.
