| The `plugin` attribute was malformed. |
| |
| Erroneous code example: |
| |
| ```compile_fail,E0498 |
| #![feature(plugin)] |
| #![plugin(foo(args))] // error: invalid argument |
| #![plugin(bar="test")] // error: invalid argument |
| ``` |
| |
| The `#[plugin]` attribute should take a single argument: the name of the plugin. |
| |
| For example, for the plugin `foo`: |
| |
| ```ignore (requires external plugin crate) |
| #![feature(plugin)] |
| #![plugin(foo)] // ok! |
| ``` |
| |
| See the [`plugin` feature] section of the Unstable book for more details. |
