Hi,
I was following the web version of gml_string and I think there is an error in the getting started part:

for (let el of document.querySelectorAll("pre:not(.gml)")) {
    el.classList.add(".gml");
    el.innerHTML = gml_string.renderToHTML(el.innerHTML, "gml"); 
}

This return:
"Uncaught TypeError: tkk is undefined"
"renderToHTML /js/gml_string.js:993"

To fix this error here is my code:

for (let el of document.querySelectorAll("code:not(.gml)")) {
    el.classList.add("gml");
    var tks = [];
    gml_string.parse(el.innerHTML, tks);
    el.innerHTML = gml_string.renderToHTML(tks, "gml");
}

Look like it was passing the wrong arg to the function renderToHtml(), tokens (tks) where missing.
Thanks for the plugin anyway, it was a bit difficult to setup cause of this but everything look fine now!

Cheers, I’ll update the doc - I think that’s a leftover from an older version.
