Great, I will try this out soon.
On Mon..Wed this week I visited the Innsbruck Isabelle site (the city of
Innsbruck is very professional in managing a lot of snow without
hindering public life :-)
I've had some discussions with users of Haskell code generation, e.g.
AFP/HLDE.
My conclusions so far:
* primary (default) output should be via the new Generated_Files
module in Isabelle/ML; thus applications can refer to file content via a
theory context, e.g. to write it to the file-system via
Generated_Files.write_files.
* secondary output works via the Export interface to Isabelle/Scala;
e.g. I could easily add Generated_Files.export_files for that and
export_code would merely use Generated_Files.add_files (no export yet).
