I'm trying to match anything that isn't a tab or space, but I end up
matching nearly everything. Here's a snip from the code:
(define tsv-lexer
(lexer
[(eof) 'EOF]
[#\space (tsv-lexer input-port)]
[#\tab (tsv-lexer input-port)]
*[(:+ (complement (:or #\Tab #\Space)))*
(begin
(display "lexeme is:")
(displayln lexeme)
(token-FIELD lexeme))]
))
If use input "AAA AAAA" I get the output:
lexeme is:AAA AAAA
but it should be matching just AAA. What's going wrong?
