Re: [Boost-users] spirit: getting scanner position from real_p

Thanks! This works like a charm. Best, Marco On Aug 4, 2008, at 4:27 PM, Hartmut Kaiser wrote:

I'm using boost spirit. I have a semantic action attached to a real_p. Is there a wy to get the current scanner position from this semantic action? For all the generic semantic actions, I can use the position_iterator, but since real_p only accepts functions/functors with a float argument, I'm kind of lost.

(real_p >> eps_p)[...]

should give you the pair of iterators.

FWIW, in Spirit2 we have the raw[] directive for that. Regards Hartmut
