Question: Where is the language class set?

Where is the language class set?

The multiple-tabs-per-language feature (issue #58) seems to have broken gulp-slate by changing the selector ("highlight.python" -> "highlight.tab-python") but not changing the class on the elements.

The effect is that the all code snippets are displayed all the time. However, this is not a problem with regular Slate only with gulp-slate. With gulp-slate, the <pre> block has the python class but not the tab-python class. Regular Slate has both classes.

If you landed here looking for a temporary workaround, a very kludgy hack is to insert the following code at the bottom of your index.html.md file.

index.html.md

<script>
function addTabPrefix(lang) { $('.highlight.' + lang).addClass('tab-' + lang); }
function fixLanguages() { $('body').data().languages.forEach(addTabPrefix); }
$(fixLanguages);
</script>

@dpilafian is it not in lib/multilang.rb L.6 ? gulp-slate doesn't seem to have an equivalent modification. Think it is an issue for that project.
Advert shins is Slate v1.5.0 compatible, though it doesn't come with its own gulp task. I don't think any of the other Node.js Slate ports have been updated yet. 1 2

👍 if this is a problem only with gulp-slate, and not us, it's probably best to submit the issue to them!

This issue was filed as a question not a bug. I intend to fix it on gulp-slate (original question noted: this is not a problem with regular Slate).

_lang.js used to look for the language class but now looks for the tab class, however the old language class remains (that's where I got derailed). Since the language class is not used by _lang.js anymore, it doesn't matter where the language class is set (although, I'm still kind of curious).

BTW, gulp-slate does indeed pull down the new multilang.rb file, but it does not appear to get executed. At least now I know where to look to fix it.

Ah, sorry, I misunderstood! Yup, multilang.rb is where it's set.

Cool, thanks!
