Last update 15/Aug/2010 by Mark Seuffert and David Fehrmann

1. Introduction

This document is for users who want to extend their chat with new features. With plugins you can add new functionality, for example show a webcam picture and integrate chat bots. For developers there is also a software development kit (Pichat SDK) to create your own plugins.
To download plugins please see Pichat downloads.

2.1. Plugin authplain

The simple user authentication plugin handles authentication for the chat and web server. All user information, including passwords as SHA256 hash or plaintext, are stored in a text file. The pipasswd program can be used to create or update your user authentication file. You can for example add registered user, chat admins and change user descriptions that are shown in the chat.

The language plugin automatically updates the European language pack for the chat server.
Here is a list of available languages:

  • bs - Bosnian by Alen Okic

  • en - English by Mark Seuffert (built-in)
  • fr - French by Thomas Pereira
  • hu - Hungarian by Miko Robert
  • sv - Swedish by Magnus Lindgren (built-in)
There are no settings for this plugin. The European language pack is called 'pichat_languages_europe.txt' and will be automatically written to the Pichat directory (or where the plugins settings are stored). More translations are welcome!

The logbot plugin records conversations on the chat server. A logbot joins chatrooms and writes chat text into logfiles, only configured chatrooms will be logged. Private messages between users are never recorded.

3. Beta plugins

There are more plugins which have not been released into public yet, they are for testers only. Here we try new ideas and features. Beta plugins have not reached sufficient software quality and probably need more time for testing. We can not guarantee that any of these plugins are free from defects or will be updated regularly. Please get in touch if you are interested.
Here is an overview of available beta plugins:
  • Plugin annabot - Anna is a multi purpose chatroom service bot, she helps to manage chatrooms and large chat communities
  • Plugin audio - A voice chat extension for the chat. This plugin is early beta state and only David really knows what it does
  • Plugin register - A web administration interface for user management. Chat users can register, change their profile and password
  • Plugin skin - A skinning plugin to customise the Windows user interface. It allows to use new graphics and backgrounds
  • Plugin talkbot - The talkbot is an experimental bot that can talk with users in the chat and answer common questions
  • Plugin whiteboard - A web-based whiteboard where users can write and draw, great for collaboration. It supports colors and images

4. Installation of plugins

Download and copy plugins into the Pichat program directory (where your pichat.exe is), then restart Pichat. You can see which plugins are installed in the chat options or with the /PLUGIN command in the chat.
There is an INI file to hold all your personal plugin settings. It is called 'pichat_plugins.ini' and stored in the Pichat directory in your home directory. On Windows you'll find it where your documents and settings are stored, enter %APPDATA% in Windows Explorer. You need to run a plugin at least once to create its settings. Some plugins contain further files for customisation, you can extract them into a subdirectory of the Pichat directory.
To uninstall simply delete the plugin files. If you need help or have ideas for new features, please talk with other users in the chat. Tip

The webchat works with nearly any web browser, easily integrated into your design, no PHP/Flash/Java required. Software for free information exchange for Linux and Windows. Built with Yellow
