I have a DSL implementation currently working with code generation, however my DSL contains some properties that I would like to do further analysis of. I think this analysis would be different than the XText validation in that the analysis could be expensive (proving properties about the DSL program) and I would like to trigger it on-demand by the user after code generation is complete. I don't want to trigger this logic every time the code is compiled.

Where would be the right place to put this logic? The analysis would need to consider the AST of the full program.

Add a special keyword like "ExpensiveAnalysis" to your grammar
and depending on that keyword run this analysis in the generator where you have the AST.

After this is done, delete the keyword (or comment it out) so your generator works the ordinary way.

Just for my curiosity: Is there a better, more obvious way to access the AST ?
