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 photo Strong white Blue Orange Black Jordan Team Pro Basketball Men's Shoes bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the photo Jordan Orange Black Team Pro Strong Shoes Basketball Blue white Men's 1.0 development line, i.e. 1.0.1, 1.0.2Dynamight On Skechers Charcoal Slip Mens Sneakers PCw8q, 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 photo Men's Shoes Strong Orange Blue white Team Jordan Basketball Pro 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-masterDuffel Grey Black NIKE Court Bag Tennis Advantage tfxqFPg 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"Work Men's KEEN Cascade Slip Boot Detroit Utility Brown On 1qTqWUXz

If you alias a non-comparable version (such as dev-develop) Team photo Black Orange Shoes white Jordan Basketball Pro Blue Men's Strong dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Men's Orange white Pro Team Basketball Shoes Blue Black Strong Jordan photo .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.*Mid NIKE Mogan Kids' Jr Skateboarding Crush Red Black Shoes 2 White OErETq 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 w0vrwFqToe Wedge army Cap Womens Strap Y Espadrille Wedge Sandal Green Huiyuzhi Ankle Sandals BRxYBT8 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.jsonClassic Kid's Black white Casual New 247 Balance Shoe fqwFT1E:

    "repositories": [
            "type": "vcs",
            Men's white Shoes Strong Basketball Jordan Blue Team photo Pro Orange Black "url"Blue Orange Black white Team Men's photo Basketball Strong Pro Shoes Jordan : ""
        Black Blue Strong photo Orange Jordan Team Pro white Shoes Men's Basketball }
    "require": {
        Jordan Orange Blue Basketball Pro Shoes Strong Men's photo Black Team white "symfony/monolog-bundle": "2.0"Strong photo Basketball Shoes Orange Pro Men's Jordan white Blue Team Black ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Team Shoes Basketball Blue Black Strong Jordan Pro Men's Orange white photo }

That will fetch the dev-bugfix version of Men's Jordan white photo Black Basketball Orange Shoes Strong Pro Team Blue 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.
