I got it… I guess.
I had to modify the `footer.hbs` file where the `syntaxHighlighterLineNumbers` is checked. I ended up adding this so that it searches for any code tags, grabs the parent tag, and appends the `line-numbers` class before prism line-numbers initializes:
{{#checkIfAll @config.custom.syntaxHighlighter @config.custom.syntaxHighlighterLineNumbers}}
<script>
var code_snippets = document.querySelectorAll('code');
for (var i = 0; i < code_snippets.length; i++) {
code_snippets.parentElement.classList.add('line-numbers');
}
</script>
<script defer src="{{js "prism-line-numbers.min.js"}}"></script>
{{/checkIfAll}}
This could be specific to the ProDocs theme. I’ve only used that one so far. But for now it works. Your mileage my vary…
