Struct TextMateEngine 

pub struct TextMateEngine { /* private fields */ }

TextMate highlighting engine. See module docs for the cache design.

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 stats(&self) -> &HighlightStats

Get performance stats for testing and diagnostics.

pub fn reset_stats(&mut self)

Reset performance counters.

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

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

pub fn notify_insert(&mut self, position: usize, length: usize)

Buffer-insert notification. Shifts span offsets in place and marks the cache dirty so the partial-update path runs on next render.

pub fn notify_delete(&mut self, position: usize, length: usize)

Buffer-delete notification. Mirror of notify_insert.

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

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

Invalidate span cache for an edited range. Checkpoint positions are handled by notify_insert/notify_delete. The span cache is NOT cleared here — it will be patched (partial update) during the next highlight_viewport call using convergence. Only dirty_from (set by notify_insert/notify_delete) controls re-parsing scope.

pub fn invalidate_all(&mut self)

Invalidate all cache and checkpoints (file reload, language change, etc.)

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
