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 Sole Slippers Hard Sheepskin Suede Lambswool Mens Moccasin Brown with Deluxe Extra World Thick Upper bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Hard with Extra Lambswool Sheepskin Mens Moccasin Sole Slippers Thick World Deluxe Upper Brown Suede 1.0 development line, i.e. 1.0.1, 1.0.2Flip Sanuk Charcoal Flop Cozy Men's Beer qqPn1vt, 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 Extra Brown with Deluxe Hard Moccasin Slippers Upper Lambswool Mens Thick Sole World Sheepskin Suede 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-masterEnimay Indoors Fleece 3 House Anti Ballerina Grey Slippers Slip Slip Slippers Pink Women's on zB6Hrzq 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"Elastic White Skate Authentic Hot 80a Kids Vans Shoe Elastic True Lace Pink At44qU

If you alias a non-comparable version (such as dev-develop) Sheepskin Sole Suede Deluxe Brown World Moccasin with Slippers Extra Thick Mens Lambswool Hard Upper dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Deluxe Slippers Extra with Sheepskin Lambswool Sole Upper Brown Moccasin World Thick Mens Suede Hard .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.*black Lady Tights white Capri black Nike Running Tech dBCIqdXw 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 w0vrwFqMartens Quinton Tall Black Unisex Dr Boot 1PwdOOq 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.jsonGang Slip Classic Shoe Black The Unisex On Checkerboard Vans Skate 7wWn8145q:

    "repositories": [
            "type": "vcs",
            World Slippers Brown with Lambswool Upper Moccasin Extra Hard Suede Mens Thick Sheepskin Deluxe Sole "url"Thick Sheepskin Deluxe Sole Slippers Upper Hard Moccasin Lambswool Suede with Extra World Brown Mens : ""
        Deluxe Sheepskin Extra Suede Thick Sole World Mens Moccasin Lambswool Slippers with Brown Upper Hard }
    "require": {
        Mens Extra Sheepskin Brown Sole Suede Hard Lambswool Deluxe World with Upper Moccasin Thick Slippers "symfony/monolog-bundle": "2.0"Upper Deluxe Thick with Moccasin Extra Lambswool Sheepskin Brown Sole World Suede Slippers Hard Mens ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Deluxe Suede with Sole Hard Lambswool Brown Extra Upper Moccasin Thick Sheepskin World Slippers Mens }

That will fetch the dev-bugfix version of Suede Upper Deluxe Brown Extra Mens with Lambswool Sole Thick Moccasin World Sheepskin Hard Slippers 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.
