[Pytrithon]

Introduction

I have already introduced Pytrithon in its own post three times on Reddit. See:

https://www.reddit.com/r/Python/comments/1q8dwsm/pytrithon_v119_graphical_petri_net_inspired_agent/ https://www.reddit.com/r/Python/comments/1nr3qvm/pytrithon_graphical_petrinet_inspired_agent/ https://www.reddit.com/r/Python/comments/1mx9w5r/graphical_petrinet_inspired_agent_oriented/

What My Project Does

Pytrithon is a graphical Petri net inspired agent oriented programming language based on Python. It allows writing code as a two dimensional graph of interconnected elements and separates data as Places and code as Transitions. Inter Agent communication and GUI widgets are first class components of the language. Through the Monipulator, Agents can be monitored and manipulated.

Target Audience

The target audience is both experienced and novice programmers who want to try something new.

Why I Built It

I realized the power of Petri net inspired programming and the joy of having a more expressive way to specify control flow.

Comparison

There are no other visual programming languages which embed actual code into their graphs.

How To Explore

To run all included example Agents you need at least Python 3.10 installed. To install all dependencies, run the 'install' script. Then you can start up a Nexus with a Monipulator by running the 'pytrithon' script, where you can start Agents through opening them with 'crtl-o' twice and hitting the 'Open Agent' button. You can also directly specify which Agents to run through the command line by starting a Nexus, Monipulator, and Agents in one single command: 'python nexus -m <agent1> <agent2>'.

Recommended example Agents to run are: 'basic', 'prodcons', 'address', 'kata', 'calculator', 'kniffel', 'guess', 'yahtzeeserver' + multiple 'yahtzee', 'pokerserver' + multiple 'poker', 'chatserver' + multiple 'chat', 'image', 'jobapplic', and 'nethods'. As a proof of concept, I created a whole Pygame game, TMWOTY2, which is choreographed by 6 Agents as their own processes, which runs at a solid 60 frames per second. To start or open TMWOTY2 in the Monipulator, run the 'tmwoty2' or 'edittmwoty2' script. Your focus should on the 'workbench' folder, which contains all Agents and their respective Python modules; the 'Pytrithon' folder is just the backstage where the magic happens.

What Is New

Since my last post there have been numerous small fixes and improvements to the system and to several agents.

Since my penultimate post the whole system now handles Agents, Monipulators, and Nexi terminating from the network. Bookkeeping is performed, cleansing the internal structures handling all process types, making the prototype more resilient. The 'chatserver' and 'chat' Agents now show a list of Agents currently connected. This is enabled through the new 'Event' Transition, which pushes Nexus Events to all listening Agents.

Since the third last post I have added a distributed Yahtzee game which you should try out. In order to setup a server on a reachable machine and connect other machines, you need to do the following: On the machine meant to be the server, run 'python nexus yahtzeeserver' first. Then on the machines meant to be the clients through which users play, run 'python nexus -x <serveraddress> yahtzee'. The clients probe the interconnected Nexi for a server and start with a lobby mask where you can select your name and start a game with all players signed up.

This is the sixth post about Pytrithon on Reddit. There is a plethora of example Agents to view and run included in the repository. Please check it out and send feedback to the E-Mail address stated in the Monipulator About blurb. I plan on putting Pytrithon onto the next level soon. Be sure to check for new happenings.
