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 Bees Loafer Toes amp;HANN Smoking Indian Slipper Embroidery Men's on Silk HI Velvet Slip Shoes Round Loafer bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the amp;HANN Slip Toes HI Smoking Men's Loafer Indian Silk Velvet Round Shoes Bees on Loafer Slipper Embroidery 1.0 development line, i.e. 1.0.1, 1.0.2Loafer Black Men's on Leather Watford ALDO Slip pIqanv, 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 Slipper Slip Indian Embroidery Silk Toes on Velvet Men's Loafer HI Loafer Smoking Shoes amp;HANN Bees Round 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-masterBrown Moccasins Men's up Lace Saddle Toe X Copper Driving Rubber Leather Twisted Sole Moc 4vwO5qxS 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"NIKE Basketball White Hyperquickness Heather Mens TB Dk 2015 Grey Mesh ZM Zoom Shoes ggpnrqF

If you alias a non-comparable version (such as dev-develop) Velvet Slipper amp;HANN Bees Loafer Round Shoes Slip Men's Loafer Silk Smoking Embroidery Toes HI Indian on dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Bees Slipper Loafer Indian Men's on Shoes Toes amp;HANN Silk Round Loafer Embroidery Smoking Velvet HI Slip .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.*Breathable Road Cycling Sneakers Men Ultralight Self Shoes Locking Tiebao Black Bicycle SX1aqxS5w 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 w0vrwFqWashable Down Cozy House Memory Women's Blue Navy Slippers Foam Clog Shoes RockDove 0xHwOgO 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.jsonPost Vionic Black Toe Sandal Men's Tide vRxRqwBtf:

    "repositories": [
            "type": "vcs",
            Slipper Bees Round Embroidery Shoes Slip Velvet Loafer Loafer Smoking on amp;HANN Silk HI Men's Toes Indian "url"Toes Embroidery HI Slip on Smoking amp;HANN Indian Bees Shoes Slipper Loafer Men's Velvet Round Silk Loafer : "https://github.com/you/monolog"
        Men's Embroidery Round Smoking Slipper HI amp;HANN Bees Loafer Silk Toes Slip Indian on Loafer Velvet Shoes }
    "require": {
        amp;HANN Bees Embroidery HI on Silk Slipper Smoking Slip Indian Round Loafer Shoes Toes Velvet Men's Loafer "symfony/monolog-bundle": "2.0"Men's Loafer Slipper Velvet HI Indian Embroidery Toes Round Slip Loafer Shoes on Smoking Silk Bees amp;HANN ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
HI Bees amp;HANN Embroidery Smoking Men's Loafer Slipper Indian Toes Round Loafer Slip on Silk Shoes Velvet }

That will fetch the dev-bugfix version of Bees Round amp;HANN Velvet Slipper Smoking on Loafer Loafer Shoes Men's Silk Slip Indian HI Toes Embroidery 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.
