haskell/haskell-language-server 0.4.0

on GitHub

0.4.0 introduces the import lens plugin, which can convert your import statements into qualified imports, or into an explicit import list:

The eval plugin has also learnt two new commands, :type and :kind:

{-# LANGUAGE TypeApplications #-}
foo :: Show a => a -> String
foo = show

-- >>> :type foo @Int
-- foo @Int :: Int -> String

-- >>> :type +v foo @Int
-- foo @Int :: Show Int => Int -> String

-- >>> type N = 1
-- >>> type M = 40
-- >>> :kind N + M + 1
-- N + M + 1 :: Nat

-- >>> type N = 1
-- >>> type M = 40
-- >>> :kind N + M + 1
-- N + M + 1 :: Nat

There is now also support for GHC 8.10.2, and a new haskell-language-server --probe-tools command to help debug what version of each tool HLS is using.

$ haskell-language-server --probe-tools
