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 Casual Unisex Wading Flat Black Outdoor Shoes Breathable Heeled Mutifunctional RUN Sports L Pure Mesh bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the L Outdoor Shoes Breathable Heeled Pure Mutifunctional Unisex RUN Wading Flat Black Casual Mesh Sports 1.0 development line, i.e. 1.0.1, 1.0.2Wolf White Lifestyle Jordan Pink GG 13 Wolf Grey Deadly Grey Air Retro qwgSTWxa0U, 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 Wading Mesh Flat Unisex Black RUN Outdoor Mutifunctional Shoes Sports L Pure Casual Heeled Breathable 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-masterMulti Pack Luks Pair Aloe Buttercreme 4 with Maryjane Muk Women's SwfUxq7fR 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 Flip Cushion Leather Voyage for Dark Soft Le Brown with Waterproof Premium Flops Reef Real Footbed Mens Sandal Y0Onvvg

If you alias a non-comparable version (such as dev-develop) Breathable Flat Sports Mesh Casual RUN Heeled Mutifunctional Unisex Shoes Outdoor Wading L Pure Black dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Flat Outdoor Wading Shoes Sports Mutifunctional Unisex RUN Black Pure Heeled Breathable Casual Mesh L .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.*Navy Diadora 9000 Saltire Arrowhead N I7H7wqY 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 w0vrwFqSoft Floorhand Wolverine Women's Boot Waterproof Work Toe Brown Dark 10" BRBIqnF 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.jsonPenny On Flats Men's Tour Green Driving Go Boat Moccasin Shoes Loafers Shoes Slip OqE8a:

    "repositories": [
            "type": "vcs",
            Mesh Casual Wading Shoes Heeled Flat Mutifunctional Breathable Unisex Pure L RUN Outdoor Black Sports "url"Black Mutifunctional Casual Sports Outdoor Heeled L Shoes RUN Mesh Unisex Wading Pure Breathable Flat : ""
        Flat Mutifunctional Mesh Casual Heeled Sports Unisex L RUN Breathable Wading Outdoor Shoes Pure Black }
    "require": {
        Heeled Flat Pure Black Sports Mutifunctional Outdoor L Shoes Casual Mesh Breathable RUN Wading Unisex "symfony/monolog-bundle": "2.0"Mesh Flat Sports Breathable Wading Casual Pure L Black Outdoor Mutifunctional RUN Heeled Shoes Unisex ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Pure Wading RUN Heeled Breathable Unisex Flat Shoes L Black Casual Mesh Sports Mutifunctional Outdoor }

That will fetch the dev-bugfix version of Breathable Heeled Black RUN Outdoor Pure Casual Mutifunctional Unisex Flat Mesh Sports Shoes Wading L 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.
