Re: [Boost-users] [Spirit] Equivalent of limit_d in spirit 2.x

Spirit 1.8 has a directive called limit_d which allowed to set the value range. Is there an equivalent for this in Spirit 2.x?

There is not anything like this, but you can achieve the same with a semantic action:

limit_d(min, max)[uint_p]

is equivalent to (when using qi::uint_, qi::_pass, and qi::_1):

uint_[_pass = (min <= _1 && _1 <= max)]

Thanks for the quick reply!

Just out of curiosity: Where can I find this in the documentation? I missed the _pass somehow.
