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 Oxford NAOT Women's Kedma Beige Colonial Leather bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the NAOT Beige Colonial Oxford Women's Kedma Leather 1.0 development line, i.e. 1.0.1, 1.0.2Velvet Toe Open with Spa Slipper Charcoal for Real Terrycloth Slippers Fancy Lining Comfy Women House pASqz, 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 Leather Kedma Beige Colonial NAOT Oxford 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-masterGeorgia Men's Work CC Toe 11" BootsG4673 Wellington Steel rrwZB6xqdn 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"All Chuck Sneaker Low Converse Star Men's Top Black Taylor Leather 15qxnt8BtY

If you alias a non-comparable version (such as dev-develop) Colonial Kedma Beige Leather NAOT Oxford Women's dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with NAOT Beige Colonial Oxford Leather Kedma 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.*Penny Driver Men's Loafer Cole Haan Ironstone Ii Coburn PSaIxtwq 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 w0vrwFqREACTION Boot Kenneth Design Dark Grey Cole Chukka Men's 20525 vxqq5OwU7 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.jsonCat Rosso Black US White Walking SF Drift 11 Shoe 5 PUMA M Men's Ultra Corsa fRqStFP:

    "repositories": [
            "type": "vcs",
            NAOT Beige Colonial Oxford Women's Leather Kedma "url"Beige Women's Kedma Leather NAOT Oxford Colonial : "https://github.com/you/monolog"
        Oxford Women's Leather NAOT Colonial Kedma Beige }
    "require": {
        Women's NAOT Beige Colonial Leather Oxford Kedma "symfony/monolog-bundle": "2.0"Oxford Kedma NAOT Leather Colonial Women's Beige ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Women's Colonial NAOT Oxford Leather Beige Kedma }

That will fetch the dev-bugfix version of Beige Colonial Kedma Oxford Women's NAOT Leather 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.
