Things we lost from Xpand ? [message #769202]

Hi,

I have been using Xtend2 for some time now, and especially the Template expressions. Xtend2 is indeed a large step forward with regard to Xtend. However, I am missing some features that were available in Xpand, but seem to be missing in Xtend2. Most notable there are
- create extensions
- protected regions
I remember that the advantage of create extension were that they saved about 30% of the work in a typical code generator. Do I now need to write this 30% extra again in Java or Xtend2 ? Or is there a good alternative that I am not seeing?

I usually try to avoid protected regions much, but for some languages it is the only way to keep generating code while handwritten text needs to be integrated. I see no alternative to protected regions at all in Xtend2. Is there one, what are people doing instead ?

Hi,

there are create extensions so i do not get this point.
and there are some open source approaches to add protected region support. https://github.com/danieldietrich/xtext-protectedregions

Christian,

Good news that create extensions still exist. I cannot find the create extension in the Xtend2 user guide (http://www.eclipse.org/Xtext/xtend/documentation/Xtend%20User%20Guide.pdf), can you point me to where they are described ?

I'll take a look at the open source approached tom the protected regions.

Thanks, Jos
