    test file for Haskell syntax highlighting in KDE's Kate

    The test file for literate Haskell can be easily created like this:
     cat highlight.hs | sed -e "s|^|> |" -e "s|> -- ||" -e "s|^> $||" > highlight.lhs
    You only have to manually edit the multi-line comment below.

    this is a single-line comment

    {- this is a multi-line comment

    Things like "a string" or a 'c' character shouldn't be highlighted in here.

    I could even start a new
    one-line comment.

    -}

    a data definition

    > data Tree a = Br (Tree a) (Tree a) | Leaf a | Nil deriving (Show, Eq)

    function definition, "funnyfunction::", "Integer", "Int", "Bool" should be highlighted

    > funnyfunction::(Tree a)=>[a]->Integer->Int->Bool

    strings and chars
    first line of function definitions (type declaration) should be highlighted

    > strangefunction::Int->String
    > strangefunction 1 = "hello"
    > strangefunction 2 = "what's up"
    > strangefunction 3 = (strangefunction 1) ++ ", " ++ (strangefunction 2)
    > strangefunction 4 = 'a':'b':'c':'"':[] -- will return "abc"
    > strangefunction 5 = '\n':[]
    > strangefunction 6 = '\invalidhaskell':[]

    function name including the single quote character
    and infix operator (`div`)

    > justtesting'::Int->Int
    > justtesting' 2 = 2+1
    > justtesting' 9 = 7 `div` 2

    same definition as above, slightly different function name and a couple more whitespaces

    > justtesting''	::	Int -> Int
    > justtesting''   2 = 3
    > justtesting''	9	=   3 + 9 - 9

    the following lines are copied out of Haskell's "Prelude.hs"

    > infixl 7  *, /, `quot`, `rem`, `div`, `mod`, :%, %

    everything highlighted except the "a"

    > class Bounded a where
    >     minBound, maxBound :: a

    > class (Num a, Ord a) => Real a where
    >     toRational     :: a -> Rational

    finally, some keyword lists

    keywords

    > case, class, data, deriving, do, else, if, in, infixl, infixr, instance, let, module, of, primitive,
    > then, type, where

    infix operators

    > quot, rem, div, mod, elem, notElem, seq
