Hello,
how is it possible to define chars as hex or unicode chars. e.g.:
fragment ALPHA
: 'a'..'z' | 'A'..'Z' | '.' | ',' | ' ' | '@'
I have a syntax in rfc2234[1] format and there hex chars are defined.
How should I transfer this to ANTLR? e.g.:
CHAR = %x01-7F
; Any C0 Controls and Basic Latin, excluding NULL from
; Code Charts, pages 7-6 through 7-9 in [UNICODE]
regards
Andreas
