Constructors
| TK !TokSymbol | Reserved word or symbol. |
| TL !String | String literal. |
| TI !String | Integer literal. |

pattern TS :: String -> Int -> Tok Source #
Smart constructor for Tok for the sake of backwards compatibility.
Keyword or symbol tokens have a unique ID.
Instances
| Show TokSymbol Source # | |
| Eq TokSymbol Source # | Keyword/symbol equality is determined by the unique ID. |
| Ord TokSymbol Source # | Keyword/symbol ordering is determined by the unique ID. |
Finite map from text to token organized as binary search tree.
eitherResIdent :: (String -> Tok) -> String -> Tok Source #
Convert potential keyword into token or use fallback conversion.
unescapeInitTail :: String -> String Source #
Unquote string literal.
alexStartPos :: Posn Source #
alexInputPrevChar :: AlexInput -> Char Source #
utf8Encode :: Char -> [Word8] Source #
Encode a Haskell String to a list of Word8 values, in UTF8 format.
