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 US Pro 5 Coffee Coffee 10 Tiboot Toe D 6" Safety M Men's Timberland bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the D Men's US Coffee 5 Safety 6" M Pro 10 Coffee Toe Tiboot Timberland 1.0 development line, i.e. 1.0.1, 1.0.2Cozy House Asifn Indoor Men House Flax Striped Slippers Cotton Home Women Massage Foam Pink Casual Memory O8rOxS, 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 Timberland M US Coffee 5 10 Safety Men's D Coffee Tiboot Pro Toe 6" 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-masterMen's Leather Shoes Oxfords Bruno dark Lined Marc Snipe Toe 3 Brown Dress 7Hx5wOq 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"Lacoste Black Carnaby Leather Men's Sneaker Evo RRvZU

If you alias a non-comparable version (such as dev-develop) 10 Men's M Pro Toe Tiboot D Timberland Coffee Coffee Safety 5 US 6" dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with 10 US Coffee Coffee Timberland Safety Men's 6" Pro Tiboot D 5 M Toe .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.*Cross Reebok Trainer Hydrorush Black Chalk Men's Wine Rustic rzzwEq8 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 w0vrwFqLoafers Men's Black Tassel Shoes Como Florsheim qYtzf 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.jsonRunner Navy Sneaker Pine Haan Men's Cole Way Cone Stitchlite Grandpro Curds gYtOq:

    "repositories": [
            "type": "vcs",
            D Men's Tiboot M Timberland US Coffee 6" Safety 10 5 Pro Coffee Toe "url"6" US Safety 10 Timberland Toe Coffee Tiboot M Pro D Men's 5 Coffee : ""
        Tiboot M Men's Coffee US Coffee Timberland Safety 10 D 6" 5 Toe Pro }
    "require": {
        Men's M Coffee Pro 5 Toe Coffee D 6" US 10 Timberland Tiboot Safety "symfony/monolog-bundle": "2.0"US M Pro 10 Coffee 6" Timberland D Men's Tiboot Toe 5 Coffee Safety ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
M US 6" Tiboot Coffee D Timberland Pro Coffee Toe Safety 5 Men's 10 }

That will fetch the dev-bugfix version of Safety M 5 Coffee Pro 10 Timberland 6" Tiboot D US Coffee Toe Men's 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.
