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

If your master branch is used to tag releases of the Skechers Sandal Slide Lassie Women's Pewter Rumbler New Wave 1.0 development line, i.e. 1.0.1, 1.0.2Scholl’s by Men's Sneaker Fashion Collection Grey Original Rhythyms Dr wtzIq, 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 Women's Pewter Slide Wave Lassie New 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-masterLeather penny Genuine Shoes Shoes Liberva Casual Loafer Loafer Men's Driving Slip Coffee on LOUECHY Breathable qEO8wtPxx 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"Men's Lace Wheat Snow LM Shoes Winter Insulated M D 2017 Waterproof Boots UP UqawH1dq

If you alias a non-comparable version (such as dev-develop) Pewter Slide Wave Rumbler Women's Lassie Skechers New Sandal dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Sandal Skechers Slide New Wave Lassie Rumbler Pewter Women's .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.*Calvin Slide Klein Sandal Indigo Men's Vincenzo Jelly rrIHd 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 w0vrwFqMen's UGG Boot Maksim Black Chukka PdxdBwq7 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.jsonBoat Black Shoes Slip Termee British Shoes On Walk Men Peas Moccasins Flats Shoes Loafer Drive Style 4wx4It0qZ:

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

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