xtext integration with gmf [message #1028033]

Hi everyone.

I've been looking for a tutorial about integration of xtext and gmf. Until now I have found diferente examples (not completly), but it seems they are deprecated for the new versions of xtext.

This is what I have found:

code.google.com/p/gmftools/wiki/GMF_and_Xtext

Also in the tutorial of the xtext page in the chapter 14 they also explain an exercise but nothing seems to work. At least in the first example I don't understando how to do to put the code of the workflow that there is available. It doesn't work.

Does anyboy have a GOOD and complete example or a tutorial to share?.

Thanks for your help

Hi Daniel,

I'm in the process of cooking up a proper Eugenia example for this. It should be done soon (we're actually implementing a new Eugenia feature to make this even easier).

Please find attached my current rough draft. This shows how to automatically parse a simple textual action language on the transitions of a simple graphical state machine. Please note that this uses both a Eugenia polishing transformation and overrides one of the GMF code generation templates.

Cheers,
Louis.

Hi Louis,

If i'm right; I must create diagram file and on label of transition element i can automatically write and parse my dsl language

but i can't get it. am i right ? or misunderstood you ?

Regards

Thanks a lot Louis for your replay.

I've been looking for your example, but just like Serhat I think that I missed something because I haven't been able to reproduce the example.
Serhat did you succeded to use the files?

Thanks again
