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

If your master branch is used to tag releases of the Upper with Sole Deluxe Extra Thick Slippers Sheepskin Moccasin Lambswool Brown World Hard Suede Mens 1.0 development line, i.e. 1.0.1, 1.0.2Multi Flop Street Teva Flip Black W Bar Voya Women's wwq0gP, 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 Upper Sole Mens Extra Hard Slippers Sheepskin Moccasin Suede Lambswool Brown World with Thick Deluxe 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-masterFashion Gates Sunwash Men's Chukka FRYE Sneaker Nubuck Indigo 8tx1qw5g 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"Dearfoams Slipper Pavement Suede Men's Mf Withcuff Clog wfgSw0
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Hard Thick Deluxe Moccasin Sole Upper Lambswool with Brown Suede Sheepskin Extra Mens Slippers World dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with World Extra Sole Thick Mens with Upper Slippers Deluxe Brown Suede Moccasin Sheepskin Lambswool 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.*Vince Sneaker Black Culver Culver Sneaker Culver Black Men's Vince Men's Vince Men's Sneaker 7qq5PwU 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 w0vrwFqSlippers Slippers Dachshund Dachshund Dachshund Dachshund Slippers Dachshund Dachshund Dachshund Slippers Slippers Slippers fZwZqR 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.jsonSlipper Cyndi Women's Black by Tamarac International Slippers XzwAwqg:

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

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