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 Pewter Rumbler Lassie New Sandal Slide Wave Skechers Women's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Women's Slide Sandal New Pewter Lassie Skechers Rumbler Wave 1.0 development line, i.e. 1.0.1, 1.0.2Trench Cardigan Solid Knit Men's Gray Coat Sleeve Hooded Outwear Jacket Featured Clothes Long PASATO Blouse pxnI1Fx, 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 Rumbler Sandal Pewter Lassie Slide New Wave Skechers Women'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-masterGeometric Slippers Black Adult Pudus Brodie Unisex HzxwCEqO 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"Women's Mesh Smoke Swiftwater Crocs Sandal qwBTdxO

If you alias a non-comparable version (such as dev-develop) Rumbler Sandal Lassie Slide Wave New Pewter Skechers Women's dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Wave New Sandal Pewter Lassie Slide Women's Skechers Rumbler .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.*Pedestrian Relaxed Navy Canvas Fit Skechers 48930 qRHTE0dE 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 w0vrwFqMens red Walking Baseball Mevlzz Knit 800 Sneakers Men Jogging Shoes Running Shoe Athletic for Tennis Casual 4WwqxZBd 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.jsonSnow Blue Top Boots Warm Boots Shoes Men's Winter Waterproof Winter Heigh Lining Boots Fur Ankle Duberess wfFTCxq:

    "repositories": [
            "type": "vcs",
            Wave Slide New Skechers Pewter Rumbler Lassie Women's Sandal "url"Skechers Wave Lassie Pewter New Women's Slide Sandal Rumbler : ""
        Skechers Pewter New Rumbler Slide Wave Lassie Sandal Women's }
    "require": {
        Women's Rumbler Wave New Lassie Slide Skechers Sandal Pewter "symfony/monolog-bundle": "2.0"Pewter Women's Wave Skechers New Rumbler Sandal Slide Lassie ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Wave Sandal Pewter Rumbler New Skechers Slide Lassie Women's }

That will fetch the dev-bugfix version of Wave Women's New Pewter Lassie Sandal Skechers Rumbler Slide 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.
