I'll try
but is that injectable?
as I said in my first post, I'd like to have something similar to
LabelProvider, say, e.g., StringRepresentationProvider, to be used in
the non-ui plugin, that users can customize.
Of course, it's quite easy to implement it (and I already have
something), but I was wondering whether xtext already had something
similar, which already uses, like LabelProvider, just not to re-invent
the wheel ;)
thanks
Lore

EmfFormatter dumps EObject trees in a readable way.
We don't have a non-UI service for configurable textual representations
of EObjects. But it should be easy to implement (PolymorphicDispatch or
EmfSwitch). If you create an interface for that you can easily bind
whatever implementation you want by means of Guice.
