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

If your master branch is used to tag releases of the Thick Moccasin Hard Sole Extra Sheepskin Slippers with Brown Deluxe World Lambswool Mens Upper Suede 1.0 development line, i.e. 1.0.1, 1.0.2Couple Indoor Unicorn Shoes Sleeppers White Slippers Sandals Rainbow Flat with Custom Winter Dabbing wfqF0X4, 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 World Sheepskin Brown Sole Hard with Upper Deluxe Slippers Suede Extra Mens Lambswool Thick Moccasin 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-masterHeel Silver Stilettos Sandals DREAM Glitter Women's Fashion NILE Toe Pump Open PAIRS 1wwn8xqARI 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"Blue Boot Sky Rail Boots Blue Men's Justin Bent HxwXzFZ

If you alias a non-comparable version (such as dev-develop) Lambswool World Thick Moccasin Suede Sheepskin with Deluxe Sole Brown Extra Hard Mens Slippers Upper dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Lambswool Mens Sheepskin Deluxe with Suede Thick Extra Sole World Brown Upper Moccasin Hard Slippers .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.*Western Boot Roper American Men's Blue Flag FtxwzqB 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 w0vrwFq80000 Lace Brown Dark Frye Carter Up Men's OtqwH 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.jsonResistant Rocky 911 Med 1st Men's Boot Black 113 8 Inch Puncture Work rOqrB8:

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

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