Hi all!

I have a question concerning validation and dependent actions.
So i have a grammar which basically defines a state machine. Also, when i start the editor, i would like to start a simulator for this state machine. The problem is, the internal structure of the simulator can only be set up correctly if there were no errors in the editor.

So i would need to follow one of the following 2 possibilities, which each raise a question:

* Is is possible to do something like "if there were no errors after validation is finished, start the simulator"? How can i determine if there were no errors in a natural way without some complicated workaround?

* Is it possible to start the simulator from somewhere else in the Xtext project? So to say - to add a piece of code somewhere that gets executed (most desirably after a correct validation) somehow Smile

. Is it possible to inject some custom components (besides the provided things in the abstract runtime module) into an Xtext project?

thanks in advance for your efforts!

I think an Xtext builder participant is the best way to go about this. For examples: see the Domain Model example shipped with Xtext or the Elysium IDE for Lilypond.
