Hi Sven,
in Xtext 1 I installed my DSL as a plugin like described in http://wiki.eclipse.org/Xtext/GettingStarted#Deployment
While developing the Xpand templates I could modify the templates, rerun the DslGenerator and then the changes were applied immediately in the generated Code.
Is there a similar way in Xtext2, or do I have to spawn a new Eclipse / reinstall the plugins after every Template/Xtend change?
Was this only possible, because Xpand was interpreted?

Thank you

The main class is not meant to get an Xtend file as a parameter but a path to a state machine model. Please use the forum at Eclipse for further technical questions :

Yeah, I tried out that but ended up with following stack trace.
Exception in thread "main" java.lang.RuntimeException: Cannot create a resource for 'DomainModelGenerator.xtend'; a registered resource factory is needed

It seems I need to register resource factory. Can you show me how to do this ?

Thanks for your time.

@Anonymous: in the generator package there should be a class called "Main" which contains what you are looking for.

Thanks for your time putting up the tutorials.
Can you point me to a sample code which shows how to run the code generator from a Java class?

Thanks

@Caner01: Please use the newsgroup for more detailed questions. If it's not a croos link and you just want proposals, you should implement it in the ProposalProvider. If it's a cross reference it belongs into the GlobalScopeProvider.

Hi, Thank you so much for magnificently useful tool.

I have just began Xtext, and had some problems;

I have a List writerNames, which contains 10000 writer's names, one of them is "Stefan King" .
I dont want to define all of them by one by, because i have ten more existing lists like this. Is there any way to get a list into my grammar?

Because While I am coding with my dsl in my
" something.mydsl " file. I want that content assist completes Stefan King", if i typed "Ste" or comes up with some names which start with "Ste"

How can I solve this?
Thanks a lot

Truly amazing work! Congratulations and thank you...

Truly amazing work!

Congratulations and thank you to Sven for tirelessly developing Xtend, Xpand, and Xbase! :)

Very nice!

Some tips for others:
- eclipse.ini after -vmargs add: -XX:MaxPermSize=256M
- In the eclipse you start from eclipse: create a new Java Project if you want to see automatic code generation work. With a normal project I did not get my statemachine code generated in /src-gen
- The help option in eclipse contains an incorrect statemachine example. You must add 'end' before resetting doorOpened D1OP if you copied it from there.
The README.TXT in the example project of the statemachine is correct.

Thy syntax diaram is displayed in a view. So it is not generated and also not persisted somehow it is just a projection of the grammar. If you want your own you'll have to use Xtext's grammar language.

2011-06-14T17:25:52.206+01:00

I've seen you can generate the Syntax diagrams of the gramatic using Xtext 2.0, so the user can see in a graphical way the options the language offers, how can I generate my own gramatic syntax diagram?

This is pretty usual; make sure to use this vm arguments in the launch configuration:

-XX:MaxPermSize=256m

hope this helps :)

@Anonymous:
There is a migration guide included in RC4 (see Eclipse Help). We will publish that to the website as well very soon.
We haven't yet written a how-to for Xbase integration, but the domain model example has Xbase integrated and should help to understand what to do. Anyway, a how-to is needed and will be written within the next couple of weeks.

Great job guys!
This is so much better than the previous versions!
I'd like to now where can I find some migration information so I can migrate the gramatics I have been developing previously?
BTW, what about Xbase? I would like to know how can I allow the use of xbase sentences on my editor

It's really incredible the things Xtext 2 does!

Many compliments! :)
