Language support for Antler

[bgarrant]

I have had this same issue for a while now and wondering if there is a work around. When I use a custom language syntax like Antlers (https://marketplace.visualstudio.com/items?itemName=ahdesign.language-antlers) for example, the HTMl Autocomplete (Intellisense) no longer functions. If I associate antlers with html then I lose the antlers syntax coloring. How can I get both Antlers (or any other language) to work alongside the HTML Intellisense since the file has an .html extension?

I am using Latest VSC 1.19.1 on a 2017 MBP High Sierra

This works in other editors such as Atom so can't figure out why VSC can get this to work? Wether I am using a Twig or Antlers extension, same issue. No HTML Autocomplete or Intellisense.

Type <div class and you will get nothing but text suggestions. and it does not even complete the <div class="">.

It all comes back to the mixed language issue. It seems VSC as no way to natively do this. Once I enable another language this is what I get for HTML autocomplete when typing <d. This is an .html file running with Antlers plugin mentioned above. All I get are text based suggestions

When in plain HTML mode on same file I lose the Antlers syntax coloring but I get this when typing same <d. This is how it should work.

Is there any way to use two languages together?

The clean way is if there's an Antler extension that implements a proper Antler language server, or forwards all requests to HTML (if Antler really compatible with HTML)

Proper Antler support should come from a Antler language server. See #47288 on why this is the best solution.

We have #49210 to think about how a simpler story to basic HTML support working in HTML template languages that don't have a language server.
