haskell - 我在哪里可以找到保留的 Haskell 关键字列表作为 [String]

Question

我生成了一些haskell 代码(在haskell 中)，我需要能够检测与haskell 关键字冲突的名称。有什么地方可以以编程方式检查 String 是否是 Haskell 关键字？

我当然可以自己编译它们的列表，但我不喜欢重新发明轮子。此外，如果引入了新关键字(通过扩展或在新规范中)，我希望此列表自动更新。

hscolour uses such a simple list for its tokenise function .

keywords =
  ["case","class","data","default","deriving","do","else","forall"
  ,"if","import","in","infix","infixl","infixr","instance","let","module"
  ,"newtype","of","qualified","then","type","where","_"
  ,"foreign","ccall","as","safe","unsafe"]
keyglyphs =
  ["..","::","=","\\","|","<-","->","@","~","=>","[","]"]
layoutchars =
  map (:[]) ";{}(),"
symbols =
  "!#$%&*+./<=>?@\\^|-~"

你可以

import Language.Haskell.HsColour.Classify

isKeyword :: String -> Bool
isKeyword = (== [Keyword]) . map fst . tokenise
