Function styled_line_to_highlighted_html

pub fn styled_line_to_highlighted_html(
    v: &[(Style, &str)],
    bg: IncludeBackground,
) -> Result<String, Error>

Output HTML for a line of code with <span> elements using inline style attributes to set the correct font attributes. The bg attribute determines if the spans will have the background-color attribute set. See the IncludeBackground enum’s docs.

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

Examples

use syntect::easy::HighlightLines;
use syntect::parsing::SyntaxSet;
use syntect::highlighting::{ThemeSet, Style};
use syntect::html::{styled_line_to_highlighted_html, IncludeBackground};

// Load these once at the start of your program
let ps = SyntaxSet::load_defaults_newlines();
let ts = ThemeSet::load_defaults();

let syntax = ps.find_syntax_by_name("Ruby").unwrap();
let mut h = HighlightLines::new(syntax, &ts.themes["base16-ocean.dark"]);
let regions = h.highlight_line("5", &ps).unwrap();
let html = styled_line_to_highlighted_html(&regions[..], IncludeBackground::No).unwrap();
assert_eq!(html, "<span style=\"color:#d08770;\">5</span>");
