I created this parser and it is working for me except the detail:
[snip code]
And the problem is in repeat_p (0, 100). I'd like to use * instead but it does not work for me because the parser runs forever. 100 means the number of blocks cpp_code_block_p or cpp_code_block_text.
Where is the problem?
The code sample you provided can be summarized as continuation = *(anychar_p - (begin|end)); all = begin >> *continuation >> end; Which, substituting continuation, is the same as: all = begin >> *(*(anychar_p - (begin|end))) >> end; The problem here is the double kleene star. The outer kleene will continue matching, in an infinite loop, as long as the inner one returns matches -- even if they're zero matches. Btw, this is a FAQ and is addressed here http://tinyurl.com/art36. When you substitute the outer * for repeat_p(0, 100) you only limit the loop. You still get 100 matches, even if they're all empty. The solution is pretty simple, and it is to remove one of the */repeat_p. For instance, continuation = *(anychar_p - (begin|end)); all = begin >> continuation >> end; Best regards, João
