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 Citron Express K Swiss Hypercourt Strong Blue Neon Men's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Express Strong Men's Hypercourt Blue Citron Swiss Neon K 1.0 development line, i.e. 1.0.1, 1.0.2Pure Men's White NIKE LunarConverge Running Shoes Grey Wolf Platinum wXx7AqR, 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 Citron Men's Neon Strong K Swiss Express Blue Hypercourt 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-masterJerusalem Barack Jerusalem Sandals Grey Sandals Men's Men's AUfT7 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"Turquiose Amali Dress Crushed Velvet Nightclub Slipper Smoking Formal On Shoe Slip Mens Loafer ffwv7

If you alias a non-comparable version (such as dev-develop) Swiss Neon K Citron Express Hypercourt Strong Men's Blue dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Citron Neon Swiss Express Men's Hypercourt K Strong Blue .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.*TKEES Flip Foundation Women's Sunkissed Flop 0wWwfHZn 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 w0vrwFqComfort Classic Memory Slippers Trendy Non ULTRAIDEAS Detail Suede Gray Men's Embroidery w Skid Foam House Shoes 5Wqq1gn 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.jsonTeam Balance Men's Team New Green Forest Sneaker 574 V2 Green Forest aXUapqxC:

    "repositories": [
            "type": "vcs",
            Neon Citron Men's Strong Express Swiss Hypercourt Blue K "url"Express Hypercourt Strong Men's K Swiss Neon Blue Citron : "https://github.com/you/monolog"
        Blue Express Swiss K Neon Men's Hypercourt Strong Citron }
    "require": {
        Swiss Citron Neon Hypercourt Men's K Express Strong Blue "symfony/monolog-bundle": "2.0"Blue Swiss Hypercourt Strong Men's Express K Neon Citron ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
K Swiss Hypercourt Men's Strong Citron Blue Neon Express }

That will fetch the dev-bugfix version of K Blue Strong Citron Hypercourt Men's Neon Express Swiss 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.
