    I am using XPand/Xtend for dynamic EMF to code generation and now I want to migrate existing Xpand/Xtend project to Xtend. I got to know that XTend is a successor of Xpand. It means I can do everything that is possible with Xpand/Xtend to latest version of Xtend (www.eclipse.org/xtend).

    I understand that Xtend is a statically-typed programming language which translates to comprehensible Java source code. I also read in some blog that dynamic EMF feature is not available in the Xtend which was previously available with XPand/Xtend. If this is true then I would like to know how can I use Xtend with dynamic metamodel which is not finalized before build.

    Let me try to summarize the question:

    I have an XSD schema (Static Meta Model) and another meta model (Dynamic meta model) which is generated from the values of an xml file whose tags are defined in the XSD schema. Right now I am able to use Dynamic meta model in case of Xpand/Xtend but now what is the way out in case of Xtend?

    Thanks and Regards, Hemal Bavishi

      Hi,

      there is not way out besides turning you dynamic stuff to somehow static stuff. but if you have an xsd schema it is not really dynamic. you can use the xsd importer to generate an ecore and generate the java classes for that ecore by creating a corresponding genmodel (this is the same a the xsd adaptor of xpand does it on the fly)
