Please describe me a starting point

[Tolga Cavdar]

Hi,

I am very interested in using CLIPS .NET but I have some big troubles.

For example, what is wrong with the code below? (Visual Basic 2008):

*************************************
Imports CLIPSNet

Module Module1

    Sub Main()

        Dim klips As New CLIPSNet.Environment

        klips.Load("blahblah.clp")
        klips.EnvReset()

        Fact.AssertString(klips, "kjk")      <-- That doesn't work!!!

    End Sub
End Module
*************************************

Visual Studio doesn't acceot " Fact.AssertString " and says that I can't use the "Fact" because "Fact is not accessible in this context because it is friend"

Can you pleeeeeeeeeeeaaaaaaaaaaaaaaase write a very basic code? I just want to make a starting point. For example just load a defrule, assert a fact and write the output to the console. That's all.

Thank you very much and looking forward the replies.

Thank you so much for your urgent reply. That's very kind of you.

I went to the address you gave and currently trying to understand the examples. But may I kindly request a "simplest" example please?

I am trying to load a clp file and assert a fact but I can't run even this!

***********************************
VB version:

Dim klips As New CLIPSNet.Environment
klips.Load("blahblah.clp")
klips.EnvReset()
Fact.AssertString(klips, "(so and so)")
klips.EnvRun()

***********************************

C# version:
CLIPSNet.Environment klips = new CLIPSNet.Environment();
klips.Load("blahblah.clp");
Fact.AssertString(klips, "(so and so)");
klips.EnvRun();
***********************************

Visual C# doesn't have a problem with "Fact" and ultimately prints the result.

Visual Basic doesn't accept to use "Fact" because it is "Firend".

BUT...

Both VB and C# complain in a console window:

[CSTRCPSR1] Expected the beginning of a construct

VB says that and that's all, it halts.
C# first says that but somehow shows the result in a second line.

Now:

1. Isn't is possible to use CLIPS .NET dll with VB?
2. What is this "[CSTRCPSR1] Expected the beginning of a construct"?
3. If C# "expected" something and seemingly could not find, how can it run anyway?

I am still crawling, please help me walking :-)

Thanks.

Okay, okay, I solved the problem and I'd like to share my solution just for helping other novices.

Problem 1. "Fact" cannot be used because it's "friend": Obviously, that issue was related with VB .NET, not with CLIPS .NET.

Solution: I added this

Imports CLIPSNet.Fact

(C# didn't require this extra "Imports" or "using" in C# syntax)

Problem 2. "[CSTRCPSR1] Expected the beginning of a construct" error: That was also not directly related to CLIPS .NET dll.

Solution: I created my rule directly in CLIPS environment, not in a text editor. I wrote the rule and save it. Then I opened it in a text browser to see whether it was different with my older rule file.

And bingo!

(defrule blahblah
     (so and so)
     =>
     (printout t "blahblah" crlf))

didn't worked because I excluded the "MAIN::" !!!

So, I re-wrote the rule as:

(defrule MAIN::blahblah
     (so and so)
     =>
     (printout t "blahblah" crlf))

That's all...
