vscode no suggestions on extern syntax

[staycoolcall911]

I tried this:

Add an extern function. There's no way for me to figure out the syntax unless I copy it from an example or the language reference. My code:

bring cloud;

class GDPRService {
  api: cloud.Api;
  bucket: cloud.Bucket;

  extern
          // ^ cursor here

  init() {
    this.api = new cloud.Api();
    this.bucket =  new cloud.Bucket();
    this.api.post("/doc/{id}", inflight (req) => {
      let id = req.vars.get("id");
      let origin = Json.stringify(req.body);
      this.bucket.put("origin${id}.txt", origin);
    });
  }
}

This happened:

No completion for the extern syntax:

I expected this:

To get a guiding docstring or syntax completion.

Is there a workaround?

@eladb Originally wanted the syntax for extern to be extern("path") instead of extern "path".

I didn't like this because it felt strange to introduce a function-call-esque modifier that didn't match other modifiers. I still feel this way, but it's not like the current method is any less unique (in a bad way). Now that we've had it for a while, pragmatically I think it makes sense to change it to extern("path") instead.

It also makes this issue significantly easier to implement. This syntax change shouldn't be difficult and IMO can be implemented as part of this issue

I'm not sure not having a completion is a bug per se (an LSP can't come up with every possible thing you can type at every position in your code), but otherwise I agree with what Mark said above.

As a related improvement, if you write

class A {
  extern foo(): str;
}

It will help if we provide a helpful syntax error, like "Missing file name after extern. Try extern "./file.js" " instead of "Unknown parser error"
