is there any way to manage this with 1.6.4
If only need to checked whether the string contains the same number of '(' and ')' what about
int counter=0;
rule<> r = ch_p('(')[increment_a(counter)]>> ~ch_p(')')>> ch_p(')')[decrement_a(counter)]
if(counter!=0) { // unbalanced! }
Unnecessary, slower, and error-prone. There is still a 'raw' equivalent in Spirit1 as I recall, but I do not know the syntax, you
Spirit1 is always "raw" in the sense that it is basically a transduction parser and returns the iterators to the matching range in the input.
