Hi, i have been trying to display the line numbers on the left side in Rust code blocks in mdbook, i want to display the line numbers without making the code block editable. Any ideas on how to do that ?

fn main() {
    println!("Hello, world!");
}

mdBook only supports line numbers on editable code blocks. According to the mdBook documentation:

  • line-numbers Display line numbers on editable sections of code. Requires both editable and copy-js to be true. Defaults to false.

If you need line numbers on non-editable code blocks, you will need to fork the mdBook code and make the changes yourself.
