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 White adidas Men's X PLR Grey Originals Running Shoe Carbon bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the X Carbon adidas PLR Originals Men's Running Grey Shoe White 1.0 development line, i.e. 1.0.1, 1.0.2Dockers Dockers Moccasin Slippers Moccasin Tan Xw4U4px, 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 PLR Grey Originals Carbon Running X adidas White Men's Shoe 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-masterFur Luxury Red Flat Soles Yu Womens Slippers Outdoor Slides Summer Soft 1 Li Raccon Indoor Shoes Real XvARvq 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"Loafer Walking A82 Shoes Summer Casual Shoes Leather red FEMAROLY Peas Men's Oxford w8vxxn0

If you alias a non-comparable version (such as dev-develop) Shoe X Men's Grey White adidas Originals PLR Carbon Running dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with adidas X PLR Grey Men's Originals Running White Shoe Carbon .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.*Matt Arch Sandal Flip for Original Orthotic Wine Flops Thong Comfort and AEROTHOTIC Comfortable Support Walk with xw6zFSqaa 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 w0vrwFqGray Naot Kirei Leather Footwear Patent Leather Suede Women's Gray Sterling T0PnaxrT 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.jsonSupra Grey Shoes Mens Skate Light White Khaki Bandit rn1rWBF:

    "repositories": [
            "type": "vcs",
            X Running Shoe adidas Men's Carbon White Grey Originals PLR "url"Men's Originals Shoe Carbon X adidas PLR White Running Grey : "https://github.com/you/monolog"
        Running X adidas Shoe White Originals PLR Men's Carbon Grey }
    "require": {
        White Running PLR Men's Shoe adidas Originals Carbon X Grey "symfony/monolog-bundle": "2.0"Men's Carbon Grey X adidas Shoe Running Originals White PLR ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Grey Men's PLR White Originals X Shoe adidas Running Carbon }

That will fetch the dev-bugfix version of adidas X PLR Shoe White Running Men's Originals Grey Carbon 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.
