Creating a GenGIS plugin

The functionality of GenGIS can be extended by writing a Python plugin. Python plugins reside in the plugins folder within your GenGIS directory. In this tutorial we will create a simple "Hello World" plugin which writes a simple greeting to the GenGIS viewport.

Required Files

Begin by creating the directory HelloWorld within the GenGIS plugins' directory. Within this directory create a file called __init__.py. This file contains general information about your plugin which is used by GenGIS to load the plugin. For our Hello World plugin, enter the following into __init__.py:

  def name():
    return "Hello World"
	
  def version():
    return "Version 1.0"

  def description():
    return "Prints Hello World to the Viewport."
	
  def authors():
    return "Donovan Parks"

  def publicationDate():
    return "March 1, 2012"
	
  def minimumVersionOfGenGIS(): 
    return "2.0"

  def requireR():
    return False
