Changes in 3.0 (since 2.3.5)
-
Unicode support (contributed mostly by Jean-Philippe Bernardy, with help from Alan Zimmerman).
-
An Alex lexer now takes a UTF-8 encoded byte sequence as input (see Section 5.1, “Unicode and UTF-8”. If you are using the "basic" wrapper or one of the other wrappers that takes a Haskell String as input, the string is automatically encoded into UTF-8 by Alex. If your input is a ByteString, you are responsible for ensuring that the input is UTF-8 encoded. The old 8-bit behaviour is still available via the --latin1 option.
-
Alex source files are assumed to be in UTF-8, like Haskell source files. The lexer specification can use Unicode characters and ranges.
-
alexGetChar
is renamed toalexGetByte
in the generated code. -
There is a new option,
--latin1
, that restores the old behaviour.
-
-
Alex now does DFA minimization, which helps to reduce the size of the generated tables, especially for lexers that use Unicode.
