Hi,

Im trying to generate java code with a package. But i cannot get the package name in my template.

Model :
name=ID
(packages+=Package)*;

Package:
"package" name=STRING '{'
(types+=Type)*
'}';

Type:
DataType | Droplet | FormHandler | Properties | JSP ;

....
...

xpand:

«DEFINE main FOR Model»
«EXPAND allpackages FOREACH packages»
«ENDDEFINE»

«DEFINE allpackages FOR Package»

«EXPAND droplet FOREACH types.typeSelect(Droplet)»
«EXPAND formhandler FOREACH types.typeSelect(FormHandler)»
......
...
«ENDDEFINE»

«DEFINE droplet FOR Droplet»
«FILE name+".java"»
«Package.name» //gives com::atg::atgdsl::atgDsl::Package
«ENDFILE»
«ENDDEFINE»

sample dsl:

package "com.user" {

datatype String

droplet SearchDroplet {

}

genrated code

com::atg::atgdsl::atgDsl::Package
public class SearchDroplet {
}

I need as follows

package com.user

public class SearchDroplet {
}

Thanks,
Arun

Hi,

you should define helper methods for that. The quick way is navigating to the container, casting to Package, obtain the name.

«FILE name+".java"»
«((Package)eContainer).name»
