Python chatbot AI that helps in creating a python based chatbot with minimal coding. This provides both bots AI and chat handler and also allows easy integration of REST API's and python function calls which makes it unique and more powerful in functionality. This AI provides numerous features like learn, memory, conditional switch, topic-based conversation handling, etc.

---

Memory

Set Memory

{ variable : value }

In think mode

{! variable : value }

Get Memory

{ variable }

Get matched group

for grouping in regex refer Python regular expression docs

Get N^th matched group of client pattern

%N

Example to get first matched

%1

Get matching named group of client pattern

%Client_pattern_group_name

Example to get matching named group person

%person

Get N^th matched group of bots message pattern

%!N

Example to get first matched

%!1

Get matching named group of bots message pattern

%!Bot_pattern_group_name

Example to get matching named group region

%!region

Recursion

Get response as if client said this new statement

{% chat statement %}

It will do a pattern match for statement

Condition

{% if condition %} do this first {% elif condition %} do this next {% else %} do otherwise {% endif %}

Change Topic

{% topic TopicName %}

Interact with python function

In python

@register_call("functionName")
def function_name(session, query):
    return "response string"

In template

{% call functionName: value %}

REST API integration

In API.json file

{
   "APIName":{
       "auth" : {
           "url":"https://your_rest_api_url/login.json",
           "method":"POST",
           "data":{
               "user":"Your_Username",
               "password":"Your_Password"
           }
       },
       "MethodName" : {
           "url":"https://your_rest_api_url/GET_method_Example.json",
           "method":"GET",
           "params":{
               "key1":"value1",
               "key2":"value2",
               ...
           },
           "value_getter":[order in which data has to be picked from json response]
       },
       "MethodName1" : {
           "url":"https://your_rest_api_url/GET_method_Example.json",
           "method":"POST",
           "data":{
               "key1":"value1",
               "key2":"value2",
               ...
           },
           "value_getter":[order in which data has to be picked from json response]
       },
       "MethodName2" : {
           ...
       },
       ...
   },
   "APIName2":{
       ...
   },
   ...
}

If authentication is required only then auth method is needed.The data and params defined in pi.json file acts as defult values and all key value pair defined in template file overrides the default value.value_getter consistes of list of keys in order using which info from json will be collected.

In Template file

[ APIName:MethodName,Key1:value1 (,Key*:value*) ]

you can have any number of key value pair and all key value pair will override data or params depending on method, if method is POST then it overrides data and if method is GET then it overrides params.

Topic based group

{% group topicName %}
  {% block %}
      {% client %}client says {% endclient %}
      {% response %}response text{% endresponse %}
  {% endblock %}
  ...
{% endgroup %}

Learn

{% learn %}
  {% group topicName %}
    {% block %}
        {% client %}client says {% endclient %}
        {% response %}response text{% endresponse %}
    {% endblock %}
    ...
  {% endgroup %}
  ...
{% endlearn %}

To upper case

{% up string %}

To lower case

{% low string %}

Capitalize

{% cap string %}

Previous

{% block %}
    {% client %}client's statement pattern{% endclient %}
    {% prev %}previous bot's statement pattern{% endprev %}
    {% response %}response string{% endresponse %}
{% endblock %}
