| `lang`    | string | No       |               | <p>Language scope to list rules for (example: <code>en\_US</code> or <code>en</code>).<br>By default returns all rules from every language.</p> |

### Behavior

* Without `lang`: lists rules in `common`.
* Without `rule`: returns all rules for the selected `lang`, grouped by style guide.
* With `rule`: returns only the matching rule(s) for the selected `lang`.

### Response

Multiple rule objects are returned.
