| #### Note: this error code is no longer emitted by the compiler. | |
| The `plugin` attribute was malformed. | |
| Erroneous code example: | |
| ```ignore (E0498 is no longer emitted) | |
| #![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! | |
| ``` | |
