Just started to work with clipspy-0.3.3 in Python 3.8.3.

When extracting facts, an inconsistency was encountered in the .facts() enumerator.

The code below

import clips

env = clips.Environment()

env.assert_string("(value 1)")
env.assert_string("(value 2)")
env.assert_string("(value 3)")
env.assert_string("(value 4)")
env.assert_string("(value 5)")
env.assert_string("(value 6)")
env.assert_string("(value 7)")
env.assert_string("(value 8)")
env.assert_string("(value 9)")
env.assert_string("(value 10)")

for fact in env.facts():
    print(fact)

Produces result

(initial-fact)
(value 1)
(value 2)
(value 3)
(value 4)
(value 5)
(value 6)
(value 7)
(value 8)
(value 9)
f-10    (value 10)

from which one can see an inconsistency in which

• facts with number less than 10, the preceding f-1 is dropped away from the fact string, and,
• facts with number equal or greater than 10, the preceding f-10 is not dropped away from the fact string.

Even if the above inconsistency can be solved with regular expression substitution, as follow

import re

for fact in env.facts():
    print(re.sub(r'^[^(]*',r'',str(fact)))

would be nice if the string representation of facts would be returned consistently by the .facts() enumerator in clispy package.

Hi, I have a problem when I use modify_slots on an instance of a subclass. Hope you can help me.
Using your code as a basis:

import clips
env = clips.Environment()

defclass = """
(defclass MyClass (is-a USER)
  (slot One)
  (slot Two))
"""

env.build(defclass)

defclass = env.find_class("MyClass")
instance = defclass.make_instance("MyInstance", One=1, Two=2)
fact = env.assert_string('(foo bar baz)')
instance.modify_slots(One=fact)

defclass = """
(defclass SUBMyClass (is-a MyClass)
  (slot Three))
"""

env.build(defclass)

defclass = env.find_class("SUBMyClass")
instance = defclass.make_instance("SUBMyInstance", One=1)
for i in env.instances():
    print(i)

This shows:

[MyInstance] of MyClass (One <Fact-1>) (Two 2)
[SUBMyInstance] of SUBMyClass (One 1) (Two nil) (Three nil)

Then, when I do this:

instance.modify_slots(Three=3)

The kernel dies...
Any idea of what I'm doing wrong?
Thanks in advance! And for your work!

Environment becomes unusable after error:

import clips

env = clips.Environment()

env.eval('(printout t "Hello World!" crlf)')

try:
    env.eval('(if (= 0 nil)then (printout t "Hello World!1" crlf))')
except Exception as e:
    print "EXCEPTION", e
    

print "attempt to call CLIPS"
env.eval('(printout t "Hello World!2" crlf)')
print "attempt to call CLIPS2"
env.eval('(printout t "Hello World!3" crlf)')

(= 0 nil) causes an error. It is expected that "Hello World!2" and "Hello World!3" would be printed as in CLIPS itself. But that doesn't happen. env.eval('(printout t "Hello World!2" crlf)') throws anv error.

Similar CLIPS example:

$ ./clips
         CLIPS (6.30 3/17/15)
CLIPS> (printout t "Hello World!" crlf)
Hello World!
CLIPS> (if (= 0 nil)then (printout t "Hello World!1" crlf))
[ARGACCES5] Function = expected argument #2 to be of type integer or float
CLIPS> (printout t "Hello World!" crlf)
Hello World!
CLIPS> (exit)

Hey there
Having successfully installed the package using "sudo make install" ( after chaning python to python3 in the 1st line) , I get the following error as I try to import clips

>>> import clips
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Why not use pip ? I am trying to use the package on raspberry pi , and of course have been able to compile clips on raspberry.
Any suggestions ?
thanks in advance

It looks like "gensym" is not exposed through API.

When an instance is created in CLIPS, instance name is optional.

$ clips
         CLIPS (6.30 3/17/15)
CLIPS> (defclass MyClass (is-a USER)
  (slot One (type INTEGER)(default 222))
  (slot Two))
CLIPS> (make-instance of MyClass)
[gen1]
CLIPS>

If instance name is not supplied, CLIPS calls (gensym) and generates a name ([gen1] in the example). It would be nice to have exactly the same behavior in clipspy.

As of now:

instance = klass.new_instance('')

would create an instance with an empty name. Pyclips would generate name in such case. Another option is use None as an indicator that clipspy should call (gensym).

There are work arounds for sure - it's easy for a user to generate some symbols by himself, but that would duplicate the feature already present in CLIPS.

On Windows Server 2016, python 3.7, importing clips gives me the below error, no matter if installed using pip install clipspy or built by myself.

if fact1, fact2, fact3 are asserted at the same time, then while using PyCLIPS depending on the order of declaration of rules in my .clp file, rule1 was fired.(because it precedes rule2)

(defrule rule1
  (fact 1)
  (fact 2)
=> printout t"rule1")

(defrule rule2
  (fact 1)
  (fact 3)
=> printout t"rule2")

but clipspy fires both the rules at the same time. This messes up the expert system as there are two ouputs on the screen.
I understand I'll have to (declare (salience __)) in each rule to prioritze rules. This is an extra burden as when my rules increase in number, its hard to keep track of salience numbers.
Is there a way to prioritize rules based on their order in the .clp file.

I have created a class instance named UniversalSample.exe.

Now I have the following string:

'(make-instance my_function of clips_NETWORK_FUNCTION (binary [UniversalSample.exe])(start_address 4278884)(function_name "blah"))'

This creates a new class instance:

clips_env.eval(make_instance_string)

Then I obtain the newly created class instance via:

instance_just_created = clips_env.find_instance(clips_instance_name)

However,

type(instance_just_created["binary"])

returns

<class 'str'>`

but not (as I expected)

<class 'clips.classes.Instance'>

How can I create a class instance that has a property pointing to another class instance that I know the name of?

Consider following example:

from clips import Environment

env = Environment()

class_string = """
(defclass MyClass (is-a USER)
  (slot One (type INTEGER)(default 222))
  (slot Two))
"""

env.eval("(watch instances)")
env.eval("(watch slots)")

env.build(class_string)

klass = env.find_class('MyClass')
instance = klass.new_instance('instance-name')
instance['Two'] = 1

print instance

Result is:

==> instance [instance-name] of MyClass
::= local slot Two in instance instance-name <- 1
[instance-name] of MyClass (One nil) (Two 1)

which is wrong. Slot One should be 222 as it is in CLIPS.

$ clips
         CLIPS (6.30 3/17/15)
CLIPS> (batch test13.clp)
TRUE
CLIPS> (defclass MyClass (is-a USER)
  (slot One (type INTEGER)(default 222))
  (slot Two))
CLIPS> 
(watch instances)
CLIPS> (watch slots)
CLIPS> 
(make-instance [r1] of MyClass)
==> instance [r1] of MyClass
::= local slot One in instance r1 <- 222
::= local slot Two in instance r1 <- nil
[r1]
CLIPS> 
(exit)

Clipspy uses void *EnvCreateRawInstance(environment,defclassPtr,instanceName); to create an instance. Documentation for this function states:

Creates an empty instance with the specified name of the specified
class. No slot overrides or class default initializations are performed
for the instance.

Warning: This function bypasses message-passing.

lib/clips.cdef:void *EnvMakeInstance(void *, const char *); should be exposed through API;

EnvCreateRawInstance is more of the internal CLIPS function. It's not really needed to be exposed through Clipspy API.

I've added a new method at my environment.py:

    def make_instance(self, inststr):
        """Create a new instance from an instance string"""
        ist = lib.EnvMakeInstance(self._env, inststr.encode())
        if ist == ffi.NULL:
            raise CLIPSError(self._env)

        return clips.classes.Instance(self._env, ist)

Hey there,
I've installed your library on RedHat7.3 VM from the sources using the Makefile provided and everything worked as expected during the process. However when I'm trying to make an Import in the python interpreter I've got the following message:

import clips
Traceback (most recent call last):
File "", line 1, in
File "clips/init.py", line 30, in
from clips.error import CLIPSError
File "clips/error.py", line 32, in

File "clips/router.py", line 7, in
from clips._clips import lib, ffi
ImportError: No module named _clips

Indeed I don't see any module named _clips in the package. Do you have any idea where I'm missing something ?

Thanks for your help.

I followed the instruction on https://pypi.org/project/clipspy/, but could net set it up.
I have compiled the clips core and cp *.h to /usr/local/include/clips and cp *.a to /usr/lib/clips
but it does not work. "Failed building wheel for clipspy"
waiting for help

From pyclips it looks like a pretty printer might be available via the underlying C API, see example 1 or example 2.

I'm currently exploring this codebase to see if something similar is available, either an API to pretty printing, or access to the underlying C library (perhaps clips._clips.ffi?).

If anyone knows, please let me know. I'll answer my own question if I find an answer. Thanks!

Use case:

I'm basically trying to turn an ugly single-line blob of Lisp-like code into something which is indented nicely.

I've tried installing on Windows 10 Pro with python 3.7 and I'm getting the following error:

build\temp.win-amd64-3.7\Release\_clips.c(523): fatal error C1083: Cannot open include file: 'clips.h': No such file or directory

I've tried using both Visual Studio Build Tools for 2015 (v14.00) and 2019, and both give me 'clips.h' error.

Also, the pypi link doesn't seem to show any wheels for windows? (If I'm wrong here let me know)

https://pypi.org/project/clipspy/#modal-close

Any advice or tips on how to solve this? I'd prefer to not install from scratch.

The error => [BLOAD2] File book.clp is not a binary construct file.

The code.

from clips import Environment, Symbol

env = Environment()

env.clear()

env.load('book.clp')

env.facts()

env.run()

book.clp file

(deftemplate book
(multislot surname)(slot name)(multislot title)
)

(deffacts initial
(book (surname J.P.)(name Dubreuil)(title History of francmasons))
(book (surname T.)(name Eker)(title Secrets of millionaire mind)))

(defrule find_title
?book<-(book(name Eker))
=>
(printout t ?book crlf)
)

when I tried code this, the method 'make_instance' cannot be found. It showed some error. There are also some other methods which behave like this.
below is the error:

Traceback (most recent call last):
  File "C:\Users\GabrielLCH\Anaconda3\envs\krr_expert_system\lib\site-packages\clips\environment.py", line 84, in __getattr__

During handling of the above exception, another exception occurred:

running python setup.py build_ext outside of sudo works without issue.

The pip installation worked fine with Python 3.7.
However, the same commands (pip install clipspy) cause the below error.

How to get the RHS of each active rule after do run

All Python classes should inherit from (object) for Python 2.7. Otherwise search in TYPES fails for classes that don't inherit from (object).

Calling a Python function that returns 'long' type fails:

From cffi callback <function python_function at 0x7f6e56f65a28>:
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/clipspy/environment.py", line 227, in python_function
    data.value = ret if ret is not None else clips.common.Symbol('nil')
  File "/usr/lib/python2.7/site-packages/clipspy/data.py", line 71, in value
    dtype = TYPES[type(value)] if self._type is None else self._type
KeyError: (<type 'long'>,)

The below code returns None, and not the name of the instance.
It seems clipspy embedded python functions cannot handle clips variables (starting with an ?).
EDIT: It works for other slots, but not for the name slot.

import clips


def python_print(string_to_print):
    print(string_to_print)


def build_instance(clips_class_name, clips_instance_name, slots=None):
    instance_string = "(make-instance " + clips_instance_name + " of " + clips_class_name + ")"
    env.eval(instance_string)
    i = env.find_instance(clips_instance_name)
    return i

    env = clips.Environment()

    """

    rule_string = """
    (defrule my_rule

    (object (is-a A)
        (name ?name_of_an_A))

    =>

    (python_print ?name_of_an_A))
    """
    env.build(class_string)
    env.define_function(python_print)
    env.build(rule_string)
    
    klass = env.find_class("A")
    i_1 = build_instance(klass.name, "i1")
    i_1["One"] = "one"


    env.run()

It looks like *build* in .gitignore matches clips_build.py

Hi Noxdafox,
first of all I'd like to thank you for your amazing work in the Python wrapping of Clips functionalities. Your library is well documentated, well written and the manual is perfect. Congrats.

That said, I've to be frank: I'm an "absolute beginner" with Expert Systems (ES) or Rules Base Systems (RBS). My goal is to produce a thesis on this matter and so I started to study some implementations in Python, that's the language I've to use.

After some searches on web I put the attention on these libraries:

1. CLIPSPY (noxdafox)
2. DURABLE RULES (jruizgit)
3. BUSINESS RULES (venmo)
   forgetting all the others minor implementations as Rule-engine, PyKnow/Experta, Python Knowledge Engine (PyKE) and so on.

Of course, the paired CLIPS + CLIPSPY stays on other planet (NASA docet...), so I kindly ask you some information and your useful tips.

It's clear that CLIPSPY is a wrapper of the underlying C functions of CLIPS; so when we design an ES or a RBS we've to think in CLIPTONIC way, not in PYTHONIC.

Keeping in mind both are OOP, do you have some advices for using directly the Object Model written in Python to create the CLIPS CLASSES and relative inheritance hierarchy? Maybe there are something I neglected, or something you have in your to top hat.
Something like this pseudocode:

CLIPSclass: str = env.CreateFromPythonObject(object)

And this also for the creation of rules, starting, somehow, from the functions of the Python object with some adorners, why not.

If there is nothing ready-to-use, I'll be happy to write some code and send to your repository, if you agree.

Thanks in advance for your kind reply, and all the best for this new year.
Ciao

Hello,

I would like to install clipspy via pip.
Unfortunately it does not work for me with Python 3.10.
With 3.9 it works.

Thanks in advance.

Many greetings!

My installed packages for 3.10. are:
cffi 1.15.1
pip 22.1.2
pycparser 2.21
setuptools 63.2.0
wheel 0.37.1
where setuptools was upgraded with pip before trying to install clipspy.

This is what the console says (VS code with Git Bash):

I asked this also in this SO post.

Is it possible to read the ErrorStream from clips using clipspy? With pyclips, it worked this way: clips.ErrorStream.Read().

Does it even make sense to do it with clipspy, or are all errors thrown as exceptions and can be caught with clips.CLIPSError ?

Hello.

I wanted to make a custom router class so that instead of outputting to a log file, I can directly get the string and parse it to create a python object.

This python object is later used to check the inference process.

I have created the following router

from clips.routers import Router
from typing import Callable

class CallbackRouter(Router):

    def __init__(self, callback: Callable, priority: int = 10):
        super().__init__("callback-router", priority)

        self.callback = callback
        self.reset_message()

    def query(self, _name: str) -> bool:
        return True
        return (_name == "stdout")

    def write(self, _name: str, _message: str):
        """
        If the message is a new-line terminate sentence,
        log it at according to the mapped level.
        Otherwise, append it to the message string.
        Same as Logging ROuter
        """
        if _message == '\n':
            self.log_message(_name)
        else:
            self._message += _message
            if self._message.rstrip(' ').endswith('\n'):
                self.log_message(_name)

    def log_message(self, name: str):
        
        if self._message:
            self.callback(self._message.lstrip('\n').rstrip('\n'))
            self.reset_message()

    def reset_message(self):
        self._meesage = ""

And a parser

from myclips.callback_router import CallbackRouter
from clips import Environment

class LogParser:
    
    def __init__(self, env: Environment) -> None:
        # Setup router
        self.router = CallbackRouter(callback=self.add_log)
        env.add_router(self.router)
        
        # Setup log
        self.reset_log()

    def reset_log(self):
        self.log : list[str] = []

    def add_log(self, message: str):
        assert type(message) is str
        self.log.append(message)

clips.Environment is passed into the LogParser and ran. But eventhough I have altered query method to return True indefinitly, nothing gets added to the self.log. I have tried this with the log router and it correctly outputs.

What might be the problem here?

I'm brainstorming about running clipspy in Flask with a stateless endpoint. E.g., the web client's asserted facts would be re-sent with every GET request. The endpoint would create a new environment for the request, and terminate it when done. The reason would be to scale well for the web.

Being able to make CLIPS web apps would be pretty powerful.

I cannot get a clips environment to load a text file. I'm on windows using clipspy 0.3.2.

Reproducible example:
simple_clips_test.py:

import clips
clips_env = clips.Environment()
demo_clips_facts_filename = "demo.clp"
clips_env.load(demo_clips_facts_filename)``

demo.clp:

;;; Class Structure
(defclass A  (is-a USER)
   (role concrete)
   (multislot secondary-types)
   (multislot hasIssue (type INSTANCE-NAME)))

(defclass B  (is-a USER)
   (role concrete)
   (multislot secondary-types))

(defclass C  (is-a USER)
   (role concrete)
   (multislot secondary-types))

(defclass D  (is-a USER)
   (role concrete)
   (multislot connectedTo (type INSTANCE-NAME))
   (multislot secondary-types))

;;; Class Instances
(definstances individuals
   (temp_a of D)
   (temp_b of D)
) ; close up definstance

When I use the CLIPS repl to load this, it works just fine:
https://imgur.com/a/VgSdrj1

When debugging, I see that self._load_text(path) is called, I'm just not sure what's causing the error.

Hello! I new to clipspy and I am currently designing some rules based on dates.
When running my test scenarios with invalid dates, I noticed that exceptions throw by my python code are not reaching my except clause.

The simplified example is:

def is_date_in_range(date: str, initial_date_range: str, final_date_range: str):
    date = datetime.strptime(date, "%Y-%m-%d")
    initial_date_range = datetime.strptime(initial_date_range, "%Y-%m-%d")
    final_date_range = datetime.strptime(final_date_range, "%Y-%m-%d")

    return initial_date_range <= date <= final_date_range


rule = """
(
  defrule issue_date_rule
    (issue_date ?issue_date)
  =>
    (bind ?is_date_in_range (is_date_in_range ?issue_date "2004-01-02" "2013-12-31"))
    (
      if (eq ?is_date_in_range TRUE) then 
        (println "condition satisfied")
      else 
        (println "condition not satisfied")
    )
)
"""

env = clips.Environment()

try:
    env.define_function(is_date_in_range)
    env.build(rule)

    env.assert_string("(issue_date \"gibberish\")")
    env.run()
except Exception as error:
    print("Found an error")

In this code snippet I am asserting gibberish to force the error on is_date_in_range, which is thrown, but my application ends without printing condition satisfied neither condition not satisfied neither Found an error.

If I debug is_date_in_range I can see on the console:

ValueError: time data 'gibberish' does not match format '%Y-%m-%d'
ffi.error: struct udfContext: wrong offset for field 'context' (cdef says 0, but C compiler says 8). fix it or use "...;" as the last field in the cdef for struct udfContext to make it flexible

On the other hand if I purposefully add a typo to my if statement, like if (eqq ?is_date_in_range TRUE) then, then I also won't see the condition satisfied neither condition satisfied, but I'll be able to catch CLIPSError and see the Found an error message printed.

I am running this snippet using Python 3.7.11 on MAC and also on Debian image, both showing the same results.

Am I missing some configuration that would allow me to catch it? I understand that defensive programming would be a better solution in this case, but I am concerned that my service won't be aware of unexpected errors.

Thanks in advance!

I am new to CLIPS and to clipsPy. I am trying to create a instance of a CLIPS class

This is the class I have defined and correctly build in my python environment (clipsPy)

ENTITIES_CLASS = """
(defclass ENTITY-CLASS (is-a INITIAL-OBJECT)
    (slot text (type STRING))
    (slot confidence (type FLOAT))
    (slot type (type SYMBOL))
)
"""
env.build(ENTITIES_CLASS)

This works as expected, but when I try to create an instance of this class:

new_instance = "(ent0-0 of ENTITY-CLASS (text 'Bruce Springsteen')(confidence 1.0)(type PER))"
env.make_instance( new_instance )

I get this empty error:

https://i.stack.imgur.com/rLTZY.png

I have tried multiple forms of building the new_instance string but none have work :

new_instance = '(ent0-0 of ENTITY-CLASS (text "Bruce Springsteen")(confidence 1.0)(type PER))'
new_instance = "(ent0-0 of ENTITY-CLASS (text 'Bruce Springsteen') (confidence 1.0) (type PER) )"

Where is my syntax error? I appreciate any help

In pyclips, one could do this:
clips.RegisterPythonFunction(function_to_register, function_name_in_clips)

In clipspy, I can only do this:
clips_env.define_function(function_to_register)

Is this by design? I tried to set the __name__ property of function_to_register but it didn't work. Is it possible to change the name?

;;---KB.clp---;;
(deftemplate fact_template
        (slot slot_1
                (type SYMBOL))
        (slot slot_2
                (type SYMBOL))
)
(assert (fact 1))
(assert (fact_template (slot_1 v1) (slot_2 v2)))
(defrule rule1
  (fact 1)
  =>
  ?p <- (fact_template (slot_1 ?s1)
  ?q <- (fact_template (slot_2 ?s2)
  (py_retract ?p ?q))

# run.py
import clips
clips_env = clips.Environment()
clips_env.load("KB.clp")

def py_retract(p, q):
    env.build('retract '+str(p))

clips_env.define_function(py_retract)
clips_env.run()

This does not works as both p and q are not fact-identifier but come as entire fact-template.
How to change only one slot of the template keeping other intact.

This is a continuation from my SO post.
After re-installing clipspy using the repo with tag 3.2, I get the errors:
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.7/site-packages/clipspy-0.3.1-py3.7-linux-x86_64.egg/clips/__init.py", line 30, in <module> from clips.error import CLIPSError

Import Error: libclips.so: cannot open shared object file: No such file or directory

Despite saying a libclips.so does not exist, I have the following files inside /usr/lib/
libclips.so.6
libclips.so.6.30

EDIT 1:
I think I fixed it. Renamed libclips.so.6 in the folder /usr/lib/ to libclips.so. Now I can import clips.

I have been working on an expert system using clipspy recently. A problem I find is whenever I build a rule, all the previous rules are lost and only one rule can be defined. This is what I have tried.

env.clear()
print("initial rule number:",len(list(env.rules()))) # show how rules when initialized
#initial rule number: 0

env.build(init_rule) # build the 1st rule
print("rule number after 1st build:",len(list(env.rules()))) # show how rules after first build
#rule number after 1st build: 1

env.build(trule) # build the 2nd rule
print("rule number after 2nd build:",len(list(env.rules()))) # show how rules after first build
#rule number after 2nd build: 1

If I also tried to merge two rule strs into one, and call env.build() once. It doesn't work.

env.clear()
print("initial rule number:",len(list(env.rules()))) # show how rules when initialized
#initial rule number: 0

two_rules = '\n'.join([init_rule,trule]) # merge two rule strs
env.build(two_rules)
 
print("rule number after build:",len(list(env.rules()))) # show how rules after build
#rule number after build: 1

I also tried to put these rules into a text file, and use env.load() function to load that file. However there is still one rule I can find.

I really run out of ways to define more than one rule. I am not sure if this is a bug, or maybe there is something I didn't do correctly. Any help is appreciated!

Would be great to have mypy type checking support.

We could add this for one function after the other. It would not interrupt the regular functioning.

Same thing as this SO post.

Is there a built-in way to get all slots and their values from an instance as a dictionary?

I created this helper function but maybe there is a better way (using the Instance class in classes.py)?

Don't worry if there isn't, just checking because I used the Slots() method in pyclips a lot.

I am using Windows. How do I tell the installer where to find the clips.h?

I tried adapting the setup.py but it did not work.

Moreover, what code exactly should I download? This one:
https://sourceforge.net/projects/clipsrules/files/CLIPS/6.30/clips_core_source_630.zip/download
?

Hey there,

I've looked at other threads addressing installation issues and didn't find an answer, probably through my own incompetence, but please stay with me..

I'm trying to install clipspy on my Mac, running os 10.14, with Python 3.7.2. Attempted running "pip install clipspy" and got this error:

build/temp.macosx-10.14-x86_64-3.7/_clips.c:523:10: fatal error: 'clips.h' file not found #include <clips.h> ^~~~~~~~~ 1 error generated. error: command 'clang' failed with exit status 1

I went to https://pypi.org/project/clipspy/#files but could not find a wheel that works.

Downloaded the .tar.gz at the above link and tried: ./pip3 install ~/Downloads/clipspy-0.3.2.tar.gz which returned the same error as above.

I have the clips source code, I'm just not sure where to place it to circumvent that error. Here is the full terminal error.

Help is much appreciated,

Everything I have tried in a Jupyter notebook so far is working perfectly except for printing from inside a rule. env.eval('(printout t "hello")') works fine but not in the consequent section of a rule, e.g. '(defrule xyz ... => (printout t "hello") ...)'.

My workarounds so far have been to write to a file (works fine), asserting printable facts and printing them (not my preference but works), and using embedded python to create a new function to print something (e.g. def myprint(str): print(str) and then using define_function() (also works).

Thanks for all the great work on this library, and I hope this turns out to be a simple thing for those CLIPS users with existing rule bases that they want to expose in Jupyter.

I can find the rules by 'find_rule',but why not provide the 'find_fact' method ?
I need help.
