我正在尝试使用 ghc-mod
vim 插件来做类型/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,
|| 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)
|| In the second argument of ‘containers-0.5.6.2:Data.Map.Base.map’, namely
|| ‘zippedMap’
|| In the second argument of ‘(GHC.Base.$)’, namely
|| ‘containers-0.5.6.2:Data.Map.Base.map
...
屏幕杂乱无章,我很难找出问题出在哪里。作为比较,这是使用 ghci
的同一个文件的错误消息:
test.hs:71:13:
Couldn't match type ‘T.Text’ with ‘[Char]’
Expected type: M.Map [Char] ([(Integer, Integer)], S.Set Integer)
Actual type: M.Map T.Text ([(Integer, Integer)], S.Set Integer)
In the second argument of ‘M.map’, namely ‘zippedMap’
In the second argument of ‘($)’, namely
‘M.map
...
有没有办法让 ghc-mod
对这些类型使用简称?
