05/26/2025, 8:57 AM@Arnab note that the toolbox is quite picky on the interpretation of the spec (it requires that is is valid), so the result you get may either be incomplete or not work at all.
This mostly depends on if the spec is valid (a lot of them aren't) or was hand rolled or contains features that aren't representable in simple generation.
