Python NLIP Repositories

This repository contains one component of the various python repositories for NLIP Proof of Concept implementation. The various repositories are:

• nlip_sdk: this provides a software development kit in python that implements the abstractions of NLIP message, submessages along with a factory to ease the creation of NLIP messages and submessages
• nlip_client: this provides a package that simplifies the task of sending NLIP messages using the base underlying protocol. The current implementation uses httpx as the base transfer package.
• nlip_server: this provides a paclage that simplifies the task of writing a server-side NLIP application. This provides the abstractions of a NLIPApplication and a NLIP Session. An application consists of multiple sessions.

The above three are the components needed to write a client or a server. To write a client, you need to use nlip_sdk and nlip_client. To write a server side application, you need to use nlip_sdk and nlip_server.

The following repositories contain a few simple clients and server side applications:

• nlip_soln: this provides a few simple prototype server side solutions using the nlip_server package
• text_client: this provides a simple text based chatbot to interface with a NLIP server
• kivy_client: this provides a python kivy based visual client to interact with an NLIP server

NLIP Server

Welcome to the NLIP Server! This project is a basic implementation of NLIP server side protocol.

This package provides a library that can easily be customized to create your own NLIP based Solution.

The package depends on the NLIP SDK package.

Installation

This project uses Poetry for dependency management. First, please install Poetry.

To set up the Python project, create a virtual environment using the following commands.

1. Create the virtual environment:

poetry env use python

2. Install the application dependencies

poetry install

Publishing the Package

To publish the package to PyPI, ensure that your changes are committed and then create a version tag. You can do this with the following commands:

git tag v0.1.0  # Replace with new version
git push origin v0.1.0

Defining a new Server Side Solution

To define a new solution, you need to provide two subclasses of the provided abstract classes: NLIPApplicaiton and NLIPSession.

These two classes are defined in module server

The main routine of the solution should call the start_server routine in module server to create an instance of the solution server-side application. start_server takes a subclass of NLIP_Application as an argument.

An example simple echo application is included in the file echo.py

To run the echo server, use the following command

poetry run fastapi dev nlip_server/echo.py
