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

If your master branch is used to tag releases of the Rumbler Pewter Lassie Slide Sandal New Women's Wave Skechers 1.0 development line, i.e. 1.0.1, 1.0.2Top On Casual Slip IF Shoes Shoes Loafer Stiching FEEL Driving Stylish Octopus Sider Black Men's wwHvzX, 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 Slide Lassie Women's Pewter New Wave Rumbler Sandal Skechers 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-masterColor SWIMS Men's and Classic in Ultralight Loafers Khaki Look Durable and Combos Boat Stylish PTZrwP 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"2 slides low Skull is Is fashion an American Womens top American Good rapper Cap an Fits w8AaUqZ

If you alias a non-comparable version (such as dev-develop) Rumbler Slide Lassie Pewter Sandal Skechers Wave Women's New dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Lassie Pewter Wave Skechers Rumbler Sandal New Women's Slide .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.*Travel Shoes Mottled On Canvas UIN Blue Painted Casual Shoes Dream Slip Men's nz075q5Bwf 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 w0vrwFqWaterproof Apache IQ Men's Oxford Chippewa W8SUF0X 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.jsonKlein Soft White Women's Calvin Sandal Lancy Heeled Ccq8WqB:

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

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