Somewhere around 2009 I did some posts here about my own modelling tool. Due to changing targets we were now in the need to reproduce our production model (used in C#) in Gemstone (some kind of work-of-proof) and I am now working on the Gemstone/Topaz source code generator. And – more or less – it worked and with a click we have 700kbyte domain model source code in Smalltalk … fine.
The generator creates source code in Topaz format – then is transferred to Linux where the code is imported via Topaz. When imported in Gemstone it can be exported again as a Monticello project.
