set_language
Description:
Associates a [class@Language] with the buffer.
Note that a [class@Language] affects not only the syntax highlighting, but also the [context classes](./class.Buffer.html#context-classes). If you want to disable just the syntax highlighting, see [method@Buffer.set_highlight_syntax].
The buffer holds a reference to language.
Parameters:
| this |
a Buffer. |
| language |
a Language to set, or null. |
