This command allows you to edit some basic composer settings in either the
local composer.json file or the global config.json file.
To edit the global config.json file:
<comment>php composer.phar --global</comment>
To add a repository:
<comment>php composer.phar repositories.foo vcs http://bar.com</comment>
You can add a repository to the global config.json file by passing in the
12 years ago
<info>--global</info> option.
To edit the file in an external editor:
<comment>php composer.phar --edit</comment>
To choose your editor you can set the "EDITOR" env variable.
To get a list of configuration values in the file:
<comment>php composer.phar --list</comment>
You can always pass more than one option. As an example, if you want to edit the
global config.json file.
<comment>php composer.phar --edit --global</comment>
