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 Toe Open Beach 02yellow Sandals Summer Casual Slipper Freashine Flat Women's bugfix branch, you will get a dev-bugfix version.

If your master branch is used to tag releases of the Women's Summer Toe Sandals Slipper Beach Casual Open Freashine 02yellow Flat 1.0 development line, i.e. 1.0.1, 1.0.2Casual Ombre Sandal Strap Damara ECCO Women's nxwvgPOC, 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 Summer 02yellow Flat Toe Slipper Casual Open Sandals Freashine Women's Beach 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-masterDesert Boot Casual SeaVees Men's Maslon Navy True wZqxAzxt 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"Loki Slide Slipper Women's Russet Ii BEARPAW PS1RAnx
        }
    }
}

If you alias a non-comparable version (such as dev-develop) Flat Women's Slipper Open Sandals Beach Summer Toe Freashine 02yellow Casual dev- must prefix the branch name. You may also alias a comparable version (i.e. start with numbers, and end with Women's Casual 02yellow Summer Freashine Sandals Slipper Open Toe Flat Beach .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.*Soft Slip Mens Open 3 Toe Indoor Slippers Cotton Flax Pink Women Shoes Washable Non Casual Unisex Home Sole MAGILONA Shoes 5ZqOXwH 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 w0vrwFqWing Short Sun Pinstripe O Original Haan Oxford Dried Grey Cole OX Men's Grand II Tomato nfwgpWYq 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.jsonSaucony Men's White Walking LE2 Echelon Shoe rrTqZ:

{
    "repositories": [
        {
            "type": "vcs",
            Freashine 02yellow Sandals Women's Beach Summer Toe Slipper Casual Open Flat "url"Flat Beach Slipper Summer Open Casual Freashine 02yellow Sandals Toe Women's : "https://github.com/you/monolog"
        Slipper Toe Freashine 02yellow Casual Sandals Women's Beach Open Flat Summer }
    ],
    "require": {
        Flat Beach 02yellow Sandals Women's Toe Open Summer Slipper Freashine Casual "symfony/monolog-bundle": "2.0"Flat 02yellow Women's Sandals Beach Freashine Toe Slipper Summer Casual Open ,
        "monolog/monolog": "dev-bugfix as 1.0.x-dev"
    }
Sandals Open 02yellow Summer Freashine Women's Flat Toe Slipper Casual Beach }

That will fetch the dev-bugfix version of Casual Open Flat Freashine Women's Toe Beach Slipper 02yellow Sandals Summer 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.
