| Using TMF xText from the commandline [message #55085] |

Hello,
I'm new to TMF xText, so forgive if this a no brainer.
- On http://wiki.eclipse.org/MWE_New_Noteworthy it is mentioned that it is
possible to run the generator from the commandline, but it doesn't explain
how to do it. Is it described somewhere else? Or could someone tell me how
to do it?
- Besides being able to run the generator from the commandline, I would
also like to run the workflow that creates the generator and the editor
from the commandline. For this I found some reference to a script, but the
script was so complex that I couldn't distill the essence of it.
- Finally I would like to be able to run the generated editor from the
commandline. Either inside the Eclipse environment or outside of it.
Currently it seems necessary to create a project...
To give some background of my questions, I'm thinking of ways to introduce
TMF xText in a traditional C/C++ style project using make. My thinking now
is to stay as close to the known structure as possible (don't start
building from ANT or...).
Kind regards,
Louis

You're welcome :-)

A brief explanation can be found here :
http://www.eclipse.org/Xtext/documentation/0_7_0/xtext.html# RuntimesetupISetup
But it is very short.
You can use the generated parser through the EMF API.
Writing the following is sufficent in order to get a parsed EMF model
from a file:
TestLanguageStandaloneSetup.doSetup();
ResourceSet resourceSet = new XtextResourceSet();
Resource resource =
resourceSet.getResource(URI.createURI("./mymodel.dsl"), true);
Model rootObject = (Model) resource.getContents().get(0);
//... do stuff with your model
This can be used without OSGi and without any Eclipse workbench
depedendency. All you need is a couple of jars on the classpath (like
EMF, Antlr, Guice, etc,). I've added the list of jars to the end of this
mail.

It is a matter of writing
new WorkflowFacade("path/to/Workflow.mwe").run();

The editor depends on the workbench, so there might be ways to use it
without projects, it is definitely not something which we did or had in
mind. So sorry I think this is not

You need at least a Java process, from where the parser etc. can be invoked.

Hi Sven,
I have been busy with some other stuff, so this project got a bit less
attention. But now I have time to continue with this again.
I have tried running the workflow for the generated generator and after
tweaking the classpath a bit, that works perfectly. Thanks for helping me
completing that step.
I noticed however that the generator doesn't perform any of the model
validation that is done in the editor. So when I make an error in the
model there is no error report.
What should I do to get the model checking and error reporting part of the
generator workflow?
I'm starting to wonder if running the workflow is the best way to do this.
Would it be better to go the ISetup way?
Do you know of an example project where the generated generator is used as
a standalone tool with syntax and semantic error reporting?
Thanks for your help,
Louis
