Struct SyntaxHighlighter 

pub struct SyntaxHighlighter { /* private fields */ }

A syntax highlighter that supports incremental parsing, multiline text, and caching of highlight results.

Implementations

impl SyntaxHighlighter

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

Create a new SyntaxHighlighter for HTML.

pub fn is_empty(&self) -> bool

pub fn update(&mut self, edit: Option<InputEdit>, text: &Rope)

Highlight the given text, returning a map from byte ranges to highlight captures.

Uses incremental parsing by edit to efficiently update the highlighter’s state.

pub fn styles( &self, range: &Range<usize>, theme: &HighlightTheme, ) -> Vec<(Range<usize>, HighlightStyle)>

Returns the syntax highlight styles for a range of text.

The argument range is the range of bytes in the text to highlight.

Returns a vector of tuples where each tuple contains:

• A byte range relative to the text
• The corresponding highlight style for that range

Example

use gpui_component::highlighter::{HighlightTheme, SyntaxHighlighter};
use ropey::Rope;

let code = "fn main() {\n    println!(\"Hello\");\n}";
let rope = Rope::from_str(code);
let mut highlighter = SyntaxHighlighter::new("rust");
highlighter.update(None, &rope);

let theme = HighlightTheme::default_dark();
let range = 0..code.len();
let styles = highlighter.styles(&range, &theme);
