[new to xtext - so please bare with me]
OK, so now I have a simple defined DSL with all the features that one can
expect from an IDE!
But how can I re-use this generated infrastructure to actually execute / run
/ interpret my langauge files?
Preferably I would like to be able to execute both from within Eclipse and
from a command line set-up.
Any hint trick suggestion greatly appreciated.
Peter

I did exactly what you are after in the Eclipse b3 project - I
implemented running/interpreting in several different ways - running the
dirty state in the editor, running from dialogs/wizards (passing in
parameters), and much more.
There is a "run" menu extension IIRC in one of the ui components that
serves as an entry point into the functionality.
