Macros with arguments

[gr-qft]

Hi,

I'd really appreciate it if someone could help me with a couple of examples of how to define macros with arguments, when using renderToString (see below). I've browsed through the docs (and the file macros.js) but I couldn't find anything. Thanks!

 const math = katex.renderToString(expr, {
    displayMode: false,
    macros
  });

Try an example:

const math = katex.renderToString(expr, {
    displayMode: false,
    macros: {
        "\\addBar": "\\bar{#1}",
        "\\bold": "\\mathbf{#1}"
    }
  });

That should enable something like \addBar{y} + \bold{H} to return

Oh I see, the keys themselves don't contain arguments, that's why I got complaints from katex. Thank you!
