CatsooLang Documentation (under construction...)

What is CatsooLang?

CatsooLang is a little Domain Specific Langage (DSL) that allows you to handle models in a textual programming way into http://www.genmymodel.com. You can handle very low level feature of your model. CatsooLang interpreter is evaluated on the client side only, there is no intensive communication with server (there is some, we will come back on this later). Here is some details about the language:

dynamic typed,
adhoc polymorphic (function overloading) and type constraints/bounds,

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

	#import 'https://gist.githubusercontent.com/aranega/03ca7cf65c879e3bf4f3/raw/refact.catsoo'

	def _logwrap(o : Object, s : String)
	{
	log(s);
	}

	def metrics()
	{
	var elems := model objects();

	[module PHP('http://www.eclipse.org/uml2/4.0.0/UML')/]

	[template public generate(c : Class)]
	[comment @main/]
	[file (c.name + '.php', false, 'UTF-8')]
	<?php
	[if (c.generalization->notEmpty())]require_once("[c.generalization.general.name/].php");[/if]
	[for (s : String \| c.interfaceRealization.contract.name)]
	require_once("[s/].php");
	[/for]
