Hi Tino,
it's nice to see that so much development is going on!
I have made some minor additions for my own use; perhaps you could consider
integrating them into the official source.
I need them to be able to show deleted readings in an interface that uses
libcg3.
The additions are:
cg3.h :
size_t cg3_cohort_numdelreadings(cg3_cohort *cohort);
cg3_reading *cg3_cohort_getdelreading(cg3_cohort *cohort, size_t which);
size_t cg3_reading_gettrace_ruletype(cg3_reading *reading_, size_t which);
libcg3.cpp :
size_t cg3_cohort_numdelreadings(cg3_cohort *cohort_) {
Cohort *cohort = static_cast<Cohort*>(cohort_);
return cohort->deleted.size();
}
cg3_reading *cg3_cohort_getdelreading(cg3_cohort *cohort_, size_t which) {
Cohort *cohort = static_cast<Cohort*>(cohort_);
// return cohort->deleted[which];
ReadingList::iterator it = cohort->deleted.begin();
std::advance(it, which);
return *it;
}
size_t cg3_reading_gettrace_ruletype(cg3_reading *reading_, size_t which) {
Reading *reading = static_cast<Reading*>(reading_);
Grammar *grammar = reading->parent->parent->parent->parent->grammar;
const Rule *r = grammar->rule_by_number[reading->hit_by[which]];
return r->type;
}
Best,
Paul Meurer
