[Clipsmm-users] an example how to use evaluate()?

[<jwm...@ao...>]

Rick,
I tried to add evaluate() to examples/environment/envsimple.cpp like this:

    CLIPS::Values vfact;         // vector of facts

    ....

    env1.reset();
    //env2.reset();
   
    vfact = env1.evaluate("(get-fact-list)");
 
    for (vector<CLIPS::Value>::const_iterator cit = vfact.begin();
     cit != vfact.end(); ++cit) {
    cout <<"Within for loop"<< endl;
    //cout << static_cast<string>(*cit) <<" ";
    }

the example compiles, but execution aborts:

$ ./envsimple
<== f-0     (initial-fact)
==> f-0     (initial-fact)
==> f-1     (in (object robot) (location RoomA))
==> f-2     (in (object box) (location RoomB))
==> f-3     (goal (action push) (object box) (from RoomB) (to RoomA))
terminate called after throwing an instance of 'std::logic_error'
  what():  clipsmm::data_object_to_values: Unhandled multifield type
Aborted

Do you find something obviously wrong there? May be you could share a
piece of code with evaluate() as an example to expedite our work?
Thanks,
Jerzy Miernik.

It appears that case MULTIFIELD is not handled within case MULTIFIELD in
function
data_object_to_values( dataObject& clipsdo ) in file factory.cpp.
In CLIPS constant.h we have #define MULTIFIELD 4 but this value is not
part of CLIPS::Type in value.h.
It looks like for evaluating commands involving facts from deftemplates
we will need vector of vectors.
I'll be looking into EnvEval(..) source to figure out how DATA_OBJECT
gets created, then try to edit
data_object_to_values. If Rick or someone else has this solved earlier
please let us know.
Regards,
Jerzy Miernik.

This actually is the case of FACT_ADDRESS (=6) within case MULTIFIELD,
after env1.evaluate("(get-fact-list)"); has been invoked.

[Clipsmm-users] changed files for env1.evaluate("(get-fact-list)"); Re: an example how to use evaluate()?

[<jwm...@ao...>]

Rick,
I edited clipsmm/ files factory.cpp, value.h, value.cpp (attached) to have
env1.evaluate("(get-fact-list)");
working. Could you please, or someone else, inspect the changes?
I'll now look at other evaluate statements to see if they work or more
changes are needed.
Sincerely,
Jerzy Miernik.
