Can I generate a block of java independent of my model? [message #1052854]

Hi,

Is it possible to have a java source code generated that is always the same no matter what is entered into the dsl. such as the code to create a GUI, and then have a few variables that are different such as color depending on the DSL.

for example my dsl only has a few rules such as

Name:
  'name' name=ID;

Colour:
    ....

then when my user is using the dsl they will enter a name and a colour, and the block of java code I have all ready written will be generated using whatever name and colour the user typed.

Hi,

do you use xbase or dont you. if simply infer the static stuff.
if not you have a custom generator anyway

Alertnatively you can bypass the JvmModelGenerator anyway and (additionally) generate own stuff too not using the inferrer stuff at all.

Hey,

Thanks for the link, I'm not using Xbase, just xTend and xText.

I curentlly have this in my .Xtend file

class GameGenerator implements IGenerator {
	
	override void doGenerate(Resource resource, IFileSystemAccess fsa) {
		fsa.generateFile(resource.className+".java", toJavaCode(resource.contents.head as Game))
	}
	
	
	def className(Resource res) {
		var name = res.URI.lastSegment
		return name.substring(0, name.indexOf('.'))
	}

def toJavaCode(Game sm) '''

	//JAVA CODE HERE 
	
	'''

}

Obviously it's not very sophisticated but it gets the job done.

In my java code there is a variable for time curentlly set to 5000 miliseconds,

So now I just need to change that depending on what the user types into the DSL and i'm set.

Smile
