See http://www.boost.org/doc/libs/1_66_0/libs/spirit/doc/html/spirit/qi/quick_reference/compound_attribute_rules.html and for example http://www.boost.org/doc/libs/1_66_0/libs/spirit/doc/html/spirit/qi/reference/directive/repeat.html . In case of repeat the attribute is vector, for raw it is iterator_range, etc. Dne st 3. 1. 2018 5:00 uživatel Michael Powell <[email protected]> napsal: > On Tue, Jan 2, 2018 at 10:56 PM, Michael Powell <[email protected]> > wrote: > > On Tue, Jan 2, 2018 at 10:19 PM, JF <[email protected]> > wrote: > >> With semantic action you must use %= instead of = > >> > >> _label %= repeat(1, 63)[_let_dig_hyp][label_validation()] > > > > Ah!
