Implementations

impl Lang

pub const fn new( name: &'static str, aliases: &'static [&'static str], grammar: LanguageFn, query: &'static str, ) -> Self

A language of your own: a grammar, its highlights query, and the fence tags it answers to. const, so it can be a static beside the built-in rows and reach Lang::highlight the same way they do.

pub fn highlight( &'static self, source: &str, ) -> Option<Vec<(Range<usize>, HighlightKind)>>

Spans over source, in bytes, in document order. None when the query does not compile against the grammar.

pub fn compiled(&'static self) -> Option<&'static Compiled>
