Struct TextMateEngine 

pub struct TextMateEngine { /* private fields */ }

TextMate highlighting engine wrapper

This struct handles the lifetime complexities of syntect by storing the syntax set and using indices rather than references.

Implementations

impl TextMateEngine

pub fn new(syntax_set: Arc<SyntaxSet>, syntax_index: usize) -> Self

Create a new TextMate engine for the given syntax

pub fn with_language( syntax_set: Arc<SyntaxSet>, syntax_index: usize, ts_language: Option<Language>, ) -> Self

Create a new TextMate engine with a tree-sitter language for non-highlighting features

pub fn language(&self) -> Option<&Language>

Get the tree-sitter language (for indentation, semantic highlighting, etc.)

pub fn highlight_viewport( &mut self, buffer: &Buffer, viewport_start: usize, viewport_end: usize, theme: &Theme, context_bytes: usize, ) -> Vec<HighlightSpan>

Highlight the visible viewport range

context_bytes controls how far before/after the viewport to parse for accurate highlighting of multi-line constructs (strings, comments, nested blocks).

pub fn invalidate_range(&mut self, edit_range: Range<usize>)

Invalidate cache for edited range

pub fn invalidate_all(&mut self)

Invalidate all cache

pub fn category_at_position(&self, position: usize) -> Option<HighlightCategory>

Get the highlight category at a byte position from the cache.

Returns the category if the position falls within a cached highlight span. The position must be within the last highlighted viewport range for a result.

pub fn syntax_name(&self) -> &str

Get syntax name
