pub struct CodeHighlighter { /* private fields */ }

Implementations

impl CodeHighlighter

pub fn new(lang: &str) -> Self

Create a highlighter for the given language hint (e.g., “rust”, “python”).

Maintains parse state across calls to highlight_spans_stateful() so multiline strings, comments, and heredocs highlight correctly. Use highlight_spans() for one-off single-line highlighting.

pub fn highlight_spans(&mut self, line: &str) -> Vec<Span<'static>>

Highlight a line and return ratatui Spans with foreground colors.

Stateful — parse state carries across calls, so multiline strings/comments highlight correctly. Call lines in order.

No background is set — the caller controls backgrounds for diff rendering.
