This isn't correct, sorry. The anychar_p parser used by itself isn't a bad thing, because it eats up only _one_ arbitrary character/token from the input stream, which may be very useful. The problematic part is the kleene_star operator, which requires some additional attention, because it "repeats" the attached parser zero or more times. So the kleene_star in conjunction with the anychar_p will eat up all your input sequence, regardless of what in contains. But this may happen with other attached parsers too. Regards Hartmut BTW: this kleene_star behaviour _is_ a FAQ, see here: http://www.boost.org/libs/spirit/doc/faq.html#kleene_star _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
