Version: 3.4.0.201306101458
Provider: Eclipse Modeling Project


Create a new project:

'File' -> 'New->Project'
select 'Acceleo Model to Text' -> 'Acceleo Project'
'Project name:' "TestAcceleoProject"
click 'Next >'
'Module Name:' "generate"
'Metamodel URIs:' click '+'
select 'Runtime Version'
select 'http://www.eclipse.org/emf/2002/Ecore'
click 'OK'
'Template Name:' "generateElement"

Edit the generate.mtl template:

there is a 'generate.mtl' file in 'src/TestAcceleoProject.main'

sobstitute the content with the follow: 

[comment encoding = UTF-8 /]
[module generate('http://www.eclipse.org/emf/2002/Ecore')]


[template public generateElement(anEClass : EClass)  { anEClassName: String = anEClass.name.toUpperFirst(); } ]
[comment @main/]

[file (anEClassName.concat('.h'), false, 'UTF-8')]
#ifndef [anEClassName/]_H_
#define [anEClassName/]_H_

class [anEClassName/]
{
public:
    explicit [anEClassName/]();
    virtual ~[anEClassName/]();

[for (a: EAttribute | anEClass.eAllAttributes) separator('\n')]
    [a.eAttributeType.name/] get[a.name.toUpperFirst()/]();
[/for]

private:
[for (a: EAttribute | anEClass.eAllAttributes) separator('\n')]
    [a.eAttributeType.name/] [a.name/];
[/for]
};

#endif

[/file]

[file (anEClassName.concat('.cpp'), false, 'UTF-8')]
#include "[anEClassName/].h"

[anEClassName/]::[anEClassName/]()
{
}

[anEClassName/]::~[anEClassName/]()
{
}

[/file]

[/template]


Create the model:

on 'Package Explorer' right click on "TestAcceleoProject" project 

'New' -> 'Other...'
select 'Ecore Tools' -> 'Ecore Diagram'
'Directory:' "/TestAcceleoProject"
'Domain file name:' model.ecore
click 'Finish'

Now create your class diagram


Generate the code:

on 'Package Explorer' right click on 'generate.mtl' file 

'Run As' -> 'Run Configurations'
select 'Acceleo Application' and click 'New launch configuration'
Name: "TestAcceleoProject generate.mtl"
Project: "TestAcceleoProject"
Main class: "TestAcceleoProject.main.Generate"
Model: "/TestAcceleoProject/model.ecore"
