Thanks for your replies...
I was looking into xcross code for 3 hours and some things got clearer but I
didn't got to understand anything that could work in my example... I will
try to figure it out tomorrow ... for example ... I do this before my main
function
The way I see it ... (I might be wrong of course)
This function creates l which is like some top level object and then it adds
it a field with hashed id "primitives" value of that is >>
value neko_installer_loader( char *argv[], int argc ) {
value l = neko_default_loader(argv,argc);
alloc_field(l,id_primitives,init_primitives());
alloc_field(l,val_id("loadprim"),alloc_function(loadprim,2,"loadprim"));
return l;
}
>> is another object which is created higher in this function and with that
include all primitives listed in primitives.h get allocated as fields of
this object
static value init_primitives() {
value primitives = alloc_object(NULL);
# define PRIM(module,name,nargs) alloc_field(primitives,val_id(#module
"@" #name "$" #nargs), alloc_function( name##__##nargs(), nargs,
#module "@" #name ))
# include "primitives.h"
return primitives;
}
and this is called even higher this basically calls DECLARE_PRIM on all
lines of primitives.h
#define PRIM(module,name,nargs) DECLARE_PRIM(name,nargs)
#include "primitives.h"
#undef PRIM
But that doesn't help me yet ... for example I don't know how I should
create that "root object"
I can't call neko_default_loader(..) as my I ahve not command line
args or what those two params are..
I don't see when neko_installer_loader is called from...
I will keep on looking at it tomorrow... if there are any simpler
smaller examples of dynamically creating "linking"
functions or variables from c++ to nekovm I would be glad..
Best regards,
Janko
