Re: Flex++ and Bison++ (instead of Flex and Bison)

This is what Ive done,
have multiple starting states, ( at least Ive done this with regular LEX and
YACC )


Have a function named "parse_init" that would do a "YYSTATE <start state>",
depending on the functionality it would do "YYSTATE START_1, YYSTATE
START_2", etc.


Then that start state in your lexer would return a bogus token like
"START_1, START_2, START_3, etc." that would force the parser into the
correct branch of the parse tree.


then the parser would say:
%start Branch1 Branch2 Branch2


Branch1: START_1 ( rest of parser branches, etc ).
Branch2: START_2, etc.
Branch3: START_3, etc.


Worked for me, I've done 3 in the same lex/yacc parser,
Good Luck!
