Support highlighting for fmt quasiquotes from PyF #652

Open declension opened 3 years ago

declension commented 3 years ago

Hi!

We've switched to using the excellent PyF, but one drawback is the things that were raw strings (now quasiquotes) are not highlighted at at all it seems (not even as a string, nor is the fmt qq specifier itself) in the IDE.

I'm not sure if there is a language to inject here (it's similar to a few templating languages I guess) (re: #445)

Here's an example test case

import PyF (fmt)

spec = 
  it "fmt QQ should work" $ do
      let a = 2 :: Double
          b = 3
          c = a / b
          string = [fmt| Look! {a} / {b} == {c:.3}|] :: String
      string `shouldBe` "Look! 2.0 / 3.0 == 0.667"

Thanks for reporting!

For me [fmt| Look! {a} / {b} == {c:.3}|] is highlighted in yellow but it contains a parser error.

Hmm, after installing PyF and enabling {-# LANGUAGE QuasiQuotes #-} it just works in beta87.
