C++ code generation with Xtext [message #648120]

Hello! I'm just learning basics of Xtext and want to know what is needed for generating C++ code from DSL programs created in Xtext? Does one need to integrate a tool EMF4CPP (and possibly replace original EMF with it) or there are other methods?

Sorry for possible duplicating. I've searched like 30 pages of the forum and haven't found anything looking alike.

Best Regards!

Hello Igor,

Xtext does not come with a predefined C++ Generator. You can take a Template Engine / Code Generator like Xpand or Acceleo and write the Templates that produce the .cpp files yourself.

Thank you Christian! Maybe you could provide me with some simple example of Xpand C++ template file?

Hi,

here a simple template for the hello world xtext sample project
(copy & paste from wikipedia)

«IMPORT org::xtext::example::mydsl::myDsl»

«EXTENSION templates::Extensions»

«DEFINE main FOR Greeting-»
«FILE name+".cpp"-»
#include <iostream>
#include <ostream>
 
int main() 
{
   std::cout << "Hallo «name»!" << std::endl;
}

«ENDFILE-»
«ENDDEFINE»

Thanks again! I wonder is it Wikipedia or Eclipsepedia because I still can't find this tutorial:(
