xzh*_*zhu 143 haskell ghc ghc-mod
我正在尝试使用ghc-modvim插件进行类型/语法检查等.但是,我发现ghc-mod总是在错误消息中使用完整的类型路径,例如:
test.hs|71 col 13 error| Couldn't match type ‘Data.Text.Internal.Text’
|| with ‘[GHC.Types.Char]’
|| Expected type: containers-0.5.6.2:Data.Map.Base.Map
|| [GHC.Types.Char]
|| ([(integer-gmp-1.0.0.0:GHC.Integer.Type.Integer,
|| integer-gmp-1.0.0.0:GHC.Integer.Type.Integer)],
|| containers-0.5.6.2:Data.Set.Base.Set
|| integer-gmp-1.0.0.0:GHC.Integer.Type.Integer)
|| Actual type: containers-0.5.6.2:Data.Map.Base.Map
|| Data.Text.Internal.Text
|| ([(integer-gmp-1.0.0.0:GHC.Integer.Type.Integer,

这会使屏幕变得杂乱,我很难找出哪里出了问题.作为比较,这是使用以下内容的同一文件的错误消息ghci:
test.hs:71:13:
Couldn't match type ‘T.Text’ with ‘[Char]’
Expected type: M.Map [Char] ([(Integer, Integer)], S.Set Integer)
Actual type: M.Map T.Text ([(Integer, Integer)], S.Set Integer)
In the second argument of ‘M.map’, namely ‘zippedMap’
In the second argument of ‘($)’, namely
‘M.map

哪个更清洁.有没有办法ghc-mod为类型使用短名称?
