LaTeX to HTML

LaTeX to HTML is a Rust library that converts LaTeX-formatted text into equivalent HTML.

This crate is designed to help developers transform LaTeX documents or fragments into structured HTML. Styling is intentionally kept minimal—developers are encouraged to apply custom CSS or integrate this library into a broader styling pipeline.

🚀 Usage

use late2htm::convert_latex_to_html;

fn main() {
    let latex_code = r"\\section{Hello}This is \\textbf{bold}.";
    let html = convert_latex_to_html(latex_code);
    println!("{}", html);
}

Additional Test Example

use late2htm::convert_latex_to_html;

fn main() {
    let input = r"\section{Main}\subsection{Sub}\subsubsection{SubSub}\paragraph{Para}\subparagraph{SubPara}Text \textbf{bold} and \textit{italic} and \underline{under} and \emph{emph}.";
    let html = convert_latex_to_html(input);
    println!("{}", html);
}
