Struct syntect::html::ClassedHTMLGenerator

pub struct ClassedHTMLGenerator<'a> { /* fields omitted */ }

Output HTML for a line of code with <span> elements using class names As this has to keep track of open and closed <span> tags, it is a struct with additional state.

There is a finalize() function that has to be called in the end in order to close all open <span> tags.

The lines returned don't include a newline at the end.

Example

use syntect::html::ClassedHTMLGenerator;
use syntect::parsing::SyntaxSet;

let current_code = r#"
x <- 5
y <- 6
x + y
"#.to_string();

let syntax_set = SyntaxSet::load_defaults_newlines();
let syntax = syntax_set.find_syntax_by_name("R").unwrap();
let mut html_generator = ClassedHTMLGenerator::new(&syntax, &syntax_set);
for line in current_code.lines() {
    html_generator.parse_html_for_line(&line);
}
let output_html = html_generator.finalize();
