Struct Lang 

pub struct Lang {
    pub name: &'static str,
    pub aliases: &'static [&'static str],
    pub grammar: Grammar,
    pub query: &'static str,
    pub injections: &'static str,
}

Fields

name: &'static str

aliases: &'static [&'static str]

grammar: Grammar

query: &'static str

injections: &'static str

Which regions are written in another language, and which. Empty is a document parsed with one grammar throughout.

Implementations

impl Lang

pub const fn new( name: &'static str, aliases: &'static [&'static str], grammar: Grammar, 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.

pub const fn with_injections(self, injections: &'static str) -> Self

Give this language an injections query. @injection.content marks the region and @injection.language names what it is written in; the name is resolved through crate::registry, so an injected language must be one the registry can paint.

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

Spans over source, through this thread’s Session.
