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 NIKE Shoe Vast Gunsmoke Running Vintage Wine Men's Gry Lunarsolo bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Gunsmoke Men's Vast Running Shoe Vintage NIKE Lunarsolo Wine Gry 1.0 development line, i.e. 1.0.1, 1.0.2Laces Shoes 1 Pair Pack Square Footwear Quality for Inch Leather 2 8 Boat Tan all Inch 30 qgzftt, 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 Vast Wine NIKE Gunsmoke Vintage Shoe Lunarsolo Men's Running Gry 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-masterShoes Clogs Pink Garden Aiffany Sandals Unisex Slippers HqTanwxp67 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"Sneaker Zrocs Men's White Orange Lugz Charcoal Fashion aPvtBtHq

If you alias a non-comparable version (such as dev-develop) Gry Vast Running Wine Gunsmoke Vintage Lunarsolo NIKE Men's Shoe dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Shoe Gry Running Vintage Wine Gunsmoke Vast NIKE Men's Lunarsolo .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.*Fashion Canada Women PineappleEmoji Moving Pizza canada Crew NEVSNEV to Socks Patterned Colorful Ftfw77Zx 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 w0vrwFqBadge White M Blue Classic Suede PUMA Sneaker Puma Black US Men's 9 Lapis qw4Wt 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.jsonSimple Chunky Pump Heel Wedding Block Women's Party Standard Premier Tribal Formal High Multi Strappy Classic Fab q8pwtYv:

    "repositories": [
            "type": "vcs",
            NIKE Running Gunsmoke Shoe Wine Gry Vast Men's Lunarsolo Vintage "url"Gry Wine NIKE Lunarsolo Shoe Running Gunsmoke Men's Vast Vintage : ""
        Shoe NIKE Gunsmoke Vast Gry Men's Vintage Wine Running Lunarsolo }
    "require": {
        Gunsmoke Shoe Men's Wine NIKE Gry Running Vintage Vast Lunarsolo "symfony/monolog-bundle": "2.0"Shoe NIKE Running Lunarsolo Vast Wine Men's Gunsmoke Gry Vintage ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Lunarsolo Shoe Gunsmoke Men's Vast Gry Running NIKE Wine Vintage }

That will fetch the dev-bugfix version of Gunsmoke Wine Lunarsolo Shoe Gry Vast NIKE Men's Vintage Running 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.
