Hi all,
Is it possible to define a project with 2 different dsl. Where every grammar has its own file extension.

Yes. Simply add multible language blocks to the workflow. Never the
less: is there a specific reason you want to do so?

I need a plugin which support two different files extension with two grammar, but the second grammar is a subset of the first.
Is it also possible to define multiple file extensions for a grammar?

Yes it is. Simply specifying a file extension list (comma separated)
in the workflow should do the trick

I developed a little project:

MyDsl.xtext
grammar org.xtext.example.mydsl.MyDsl with org.eclipse.xtext.common.Terminals

generate myDsl "xtext.org/example/mydsl/MyDsl"


ImportDeclaration: {ImportDeclaration}

MyNewDsl.xtext
grammar org.xtext.example.mydsl.MyNewDsl with org.xtext.example.mydsl.MyDsl

generate myNewDsl "xtext.org/example/mydsl/MyNewDsl"

import "xtext.org/example/mydsl/MyDsl" as DSL

Package: {Package}
			'ciao 'impor=Name '!'
			;


GenerateMyDsl.mwe2

I haven't error lauching the MWE WORKFLOW and even launching the plugin, but it don't recognize the "MyNewDsl" grammar and its extension, any suggestion?

Hi,

did you create a new project using the wizard or did you adapt an existing one.
if you adapted an existing dont forget to merge plugin.xmk_gen -> plugin.xml

Hmmm,

i think the best is:
- create a new project with the wizard
- adapt the workflow
- run the workflow

btw i use Xtext 2.x you seem to use 1.x

~Christian

Yes I use Xtext 1.x, it don't work even starting a new project.
But on Xtext 2.x everything works fine. I think I must migrate on Xtext 2.x.
Thanks Cristian
