My clip file contains (printout t"text")
and bind ?var (read)
statements. If I run the .clp file from below C code, the program prints to console and reads my input from console as expected, thus making it an interactive session between program and the user.
#include "clipscpp.h"
#include <iostream>
#include<stdlib.h>
using namespace std;
int main()
{
CLIPS::CLIPSCPPEnv theEnv;
theEnv.Load("KB.clp");
theEnv.Reset();
theEnv.Run(-1);
return 0;
}
But, If I try to load .clp in python using PyCLIPS, neither (printout)
nor (read)
works and the program terminates without doing anything.
import clips
clips.Load("KB.clp")
clips.Clear()
clips.Reset()
clips.Run(-1)
How can I achieve the same result as running from C ?

I would suggest something like that:
def parse_trace_stream(trace_stream):
...
"""Print trace_stream"""
def parse_stdout_stream(stdout_stream):
...
"""Print stdout_stream"""
def parse_error_stream(error_stream):
...
"""Print error_stream"""
def evaluate(str):
if str.count("(") == str.count(")"):
try:
clips.Eval(str)
except:
parse_error_stream(clips.ErrorStream.Read())
parse_stdout_stream(clips.StdoutStream.Read())
parse_trace_stream(clips.TraceStream.Read())
After that, you can write more CLIPS-like code:
evaluate("(load KB.clp)")
evaluate("(clear)")
evaluate("(reset)")
evaluate("(run -1)")

The FAQ for PyCLIPS (http://pyclips.sourceforge.net/web/?q=view/faq) suggests that you use Python functions for handling I/O.
