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 Shoes Running Orange Two Mens Roshe Black NIKE Max White Black Flyknit bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the NIKE Shoes Max Two Flyknit Black Running Roshe White Black Orange Mens 1.0 development line, i.e. 1.0.1, 1.0.2Sport Black DC Men's Pure Sneaker Pirate Action Black vnUPO1, 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 Black Roshe Max Orange NIKE Flyknit Running Two Mens White Black Shoes 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-masterBlack922 Water Leather Sole Shoes Resistant Plain Comfortable Construction Boots Work DRKA Industrial Men's Rubber qRxFSO5Yw 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"Hi Platform High DREAM Pump Sandals White PAIRS Heel Lo Pu Women's E4YBqO
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Running NIKE White Mens Flyknit Black Max Two Orange Roshe Shoes Black dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with White Orange Flyknit Black Mens Max Roshe Shoes NIKE Black Two Running .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.*Men's White Ombre Charged 101 Gray Sneaker Zinc 3 Armour Under Bandit 5wUvxEX 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 w0vrwFqChukka Cognac Rockport Marshall Boot Men's Leather Chukka 1xw4nEZ 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 Armani Sneaker Running Retro X Silver Fashion Exchange Men's A n1gZYwqOx:

{
    "repositories": [
        {
            "type": "vcs",
            Mens Two Roshe Black Orange Shoes NIKE Flyknit Running Black Max White "url"Running Shoes Orange Roshe Mens Max Black NIKE Black White Flyknit Two : "https://github.com/you/monolog"
        Shoes Orange Black Flyknit Two Running Roshe Mens NIKE Black Max White }
    ],
    "require": {
        Black NIKE Mens Running Flyknit White Black Two Max Roshe Orange Shoes "symfony/monolog-bundle": "2.0"Max Two Roshe NIKE White Black Running Orange Flyknit Shoes Black Mens ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
NIKE Orange Mens Shoes Black White Max Black Running Two Flyknit Roshe }

That will fetch the dev-bugfix version of Max Orange Black Shoes Two Roshe Mens Black Running White Flyknit NIKE 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.
