Hi
I use c runtime libantlr3c-3.1.3. The generated lexer is bigger than
10 MB full of arrays of integers. I tried to see what was going on and
I found there was a rule:
NQCHAR_NO_ALPHANUM
: ~('\n'|'\r'|'
'|'\t'|'\\'|CARET|QMARK|COLON|AT|SEMIC|POUND|SLASH|BANG|TIMES|COMMA|PIPE|AMP|MINUS|PLUS|PCT|EQUALS|LSQUARE|RSQUARE|RPAREN|LPAREN|RBRACE|LBRACE|DOLLAR|TICK|DOT|LT|GT|SQUOTE|QUOTE|'a'..'z'|'A'..'Z'|'0'..'9')+;
If I remove the rule, the lexer is only 400 KB.
I'm still new to antlr and I'm not sure if there is any way to
refactor the rule and reduce the size of lexer. Could anyone please
help me out?
