Subject: I don t get the lexer
Date: Sun, 12 Feb 2006 17:33:06 +0000 [thread overview]
Message-ID: <43EF7152.6080307@email.sjsu.edu> (raw)
Hello everyone
how come my lexer does not break "?!" both defined as keywords but puts
"." aside?
# let lexer = make_lexer [".";"!";"?"];;
val lexer : char Stream.t -> Genlex.token Stream.t = <fun>
# let token_stream = lexer(Stream.of_string "hello! but ?! but!?. . jhg.");;
val token_stream : Genlex.token Stream.t = <abstr>
# Stream.next token_stream;;
- : Genlex.token = Ident "hello"
# Stream.next token_stream;;
- : Genlex.token = Kwd "!"
# Stream.next token_stream;;
- : Genlex.token = Ident "but"
# Stream.next token_stream;;
- : Genlex.token = Ident "?!"
# Stream.next token_stream;;
- : Genlex.token = Ident "but"
# Stream.next token_stream;;
- : Genlex.token = Ident "!?"
# Stream.next token_stream;;
- : Genlex.token = Kwd "."
# Stream.next token_stream;;
- : Genlex.token = Kwd "."
# Stream.next token_stream;;
- : Genlex.token = Ident "jhg"
# Stream.next token_stream;;
- : Genlex.token = Kwd "."
