Re: [gef-dev] Latest Zest for GEF-classic

[Alois Zoitl <alois.zoitl@xxxxxx>]

Hi,

I agree that having Xtext as dependency for GEF classic in general is not something I see as a good idea. However I could see an optional Zest feature (dot, or
cloudio) which would need it. So users that would like to use this optional feature would get the Xtext dependency. 

But all in all it looks like a bit more work. This could be a very nice topic for a bachelor thesis. I'll put it on my list of bachelor thesis topics. Maybe I
found a student to look into it. 

FYI I have currently one student doing his bachelor thesis on Zest and I find it a very nice experience for both him and me.

BR,
Alois
