Well, it turns out I really do want to do this without a predefined C++ class,
or something like that.
I want to have the C++ code be easily extensible, so I don't have to repeat
myself too much when adding new attributes. I tried making the proxy C++ class
and exposing it, but it's very verbose and hard to maintain.
I switched to using a dict, and what I have now is almost there:
static bp::list EXTget_effects()
{
bp::list effect_list;
int n_effects = get_n_sapphire_effects();
for (int i = 0; i < n_effects; i++) {
Plugin_Info *pinfo = get_plugin_info_i(i);
bp::dict ppinfo;
ppinfo["name"] = (std::string)pinfo->plugin_name;
ppinfo["category"] = (std::string)pinfo->category;
ppinfo["n_effects"] = (int)pinfo->n_effects;
ppinfo["n_inputs"] = (int)pinfo->n_inputs;
ppinfo["custom_p"] = (int)pinfo->custom_p;
effect_list.append(ppinfo);
}
return effect_list;
}
So now it returns a python list of python dicts. All I want now is to override
__getattr__ on each ppinfo dict so it returns the dict value as the attribute
value, so in python I can reference effect_list[i].name instead of
effect_list[i]['name']. Or any alternative way to get the same effect. Is
that possible?
