GMF Notation Model for Python

This little tutorial shows "in depth" how to generate Python/PyEcore code for the GMF-Notation metamodel using pyecoregen.

Generating the Metamodel Code

First, due to some dependencies expressed in the GMF Notation .ecore (relative paths towards other .ecore), it is required to have the full GMF Notation

	class MList(object):
	def __init__(self, owner, feature):
	self.innerlist = []
	self.owner = owner
	self.feature = feature

	def size(self):
	return len(self.innerlist)

	def append(self, value, update_opposite=True):

	using UnityEngine;
	using UnityEngine.UI;

	public class HexGridLayout : LayoutGroup {


	const float SQUARE_ROOT_OF_3 = 1.73205f;

	public enum Axis { Horizontal = 0, Vertical = 1 }
	public enum Constraint { Flexible = 0, FixedColumnCount = 1, FixedRowCount = 2 }

	from pyecore.resources import ResourceSet
	from pyecore.utils import dispatch
	import pyecore.ecore as ecore


	class PlantUMLSwitch(object):
	def __init__(self):
	self.visited = set()

	@dispatch

	#
	set -g default-terminal screen-256color
	set -g status-bg blue
	set -g status-fg white
	set -g status-right '#(sysctl vm.loadavg)'
	setw -g window-status-current-attr underscore
	bind r source-file ~/.tmux.conf

	require 'nokogiri'
	require 'open-uri'
	require 'cgi'

	episodes = Array.new

	doc = Nokogiri::HTML(open("http://www.notificationcenter.tv/feed.rss"))

	episodes = doc.xpath("//item")

	from pyecore.resources import ResourceSet
	from pyecore.utils import dispatch
	from enum import unique, Enum
	from functools import wraps

	import pyecore.ecore as ecore
