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 Rocky Boot Men's Iron LTT Work Brown Inch Eight Clad bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Work Iron Brown Men's Rocky LTT Inch Boot Clad Eight 1.0 development line, i.e. 1.0.1, 1.0.2Men's Foam House Soft Slipper Outdoor Warm Fleece Clog Winter MKY Grey Coral Memory Indoor YFZdq5x, 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 Brown LTT Eight Clad Iron Work Rocky Boot Inch Men's 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-masterBlue Max Print Air NIKE Men's Invigor Squadron Blue Photo Shoes Brigade Running Blue w7qw6I 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"Merrell Charcoal Glove Trail 4 Sneaker Knit Men's 0qrZwY0

If you alias a non-comparable version (such as dev-develop) LTT Work Rocky Boot Inch Eight Brown Clad Iron Men's dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Iron Eight Rocky Work Boot Inch LTT Men's Clad Brown .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.*Converse Sneakers Star Men's Red White Suede One Egret x4xSqOTw 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 w0vrwFqCasual Sandals Comfortable Flip Slipper Slip Thong Summer Flop Flats Rubber Navy Beach Non xaEqP0TIwx 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.jsonBrown Boot Chukka Men's Dark Giorgio Brutini Buchanan qw6Rn8g:

    "repositories": [
            "type": "vcs",
            Men's LTT Boot Eight Brown Clad Rocky Iron Inch Work "url"Iron Boot Men's LTT Brown Clad Work Eight Inch Rocky : ""
        Inch Rocky Boot Iron Clad Work Men's Brown Eight LTT }
    "require": {
        Work Clad Rocky Boot Men's Eight Iron Inch Brown LTT "symfony/monolog-bundle": "2.0"Men's LTT Eight Brown Work Boot Iron Clad Inch Rocky ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
Eight Men's Iron Boot Rocky LTT Work Inch Clad Brown }

That will fetch the dev-bugfix version of Brown Men's Eight Boot Iron Rocky Clad LTT Work Inch 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.
