Hi All,

Can some please pass me any small example (or link to) of generating Java code from the domain models using EGL/EOL.

Regards,
Arnaldo

Hi Arnaldo,

I'm not sure which domain models you're referring to :-/.

Regardless, here's an example for using EGL to generate HTML code from a model. Generating Java code is pretty much the same, except you might want to register an appropriate formatter:

Did that help?

Antonio

Hi Antonio

Thanks, but I am referring to XMI based models drawn on EMF/GMF editor, as processing of generating code from domain specific modeling language.

Also, how to of register an appropriate formatter such for JAVA.

Any guide would help a lot.

Hi,

I have found some example on the use of formatter to genarate EGL template based Java code

[%
 var f = new Native("org.eclipse.epsilon.egl.formatter.language.JavaFormatter");
 var t = TemplateFactory.load("generate_some_java.egl");
 t.setFormatter(f);
 t.generate("formatted.java");
 %]

However, would it be possible to have look at some EGL template and generated Java code, to understand better on its use. This would help including me all the newcomers to utilize EOL/EGL for model-to-text transformation.

Regards,
Arnaldo

Hi All,

Can someone please provide me with an example/snippet of EGL template, specified for generating Java code.

Any EGL template is sufficient:

[%
  var className = "MyClass";
%]
/**
 * Header of [%= className %]
 */

class [%= className %] {
  // Add methods
}

This might be a bit boring as it just generates an empty class (with a static name), so you'd need to expand it with more useful stuff.
