Instances

HasSpanInfo SrcSpanInfo

HasSpanInfo a => HasSpanInfo (Tree a)

srcSpan :: HasSpanInfo x => x -> SrcSpan

srcLoc :: HasSpanInfo x => x -> SrcLoc

endLoc :: HasSpanInfo x => x -> SrcLoc

textEndLoc :: String -> SrcLoc

increaseSrcLoc :: String -> SrcLoc -> SrcLoc

Update a SrcLoc to move it from l past the string argument.

textSpan :: String -> SrcSpanInfo

srcPairTextHead :: SrcLoc -> SrcLoc -> String -> String

Return the beginning portion of s which the span b thru e covers, assuming that the beginning of s is at position b - that is, that the prefix of s from (1,1) to b has already been removed.

srcPairTextTail :: SrcLoc -> SrcLoc -> String -> String

Like srcPairTextHead, but returns the tail of s instead of the head.
