Let the developers know what you think of the software and what can be done to either improve the CFDG language or the Context Free program.

Referencing non-existing rules should generate an error

Post by TorfusPolymorphus »

Sometimes after changing a rule name I forget updating a call to that call, thus calling a rule which doesn't exist. Currently (2.2) this is simply ignored by CFDG. I'd rather see an error message, though, since this simply is an error and I can't imagine a situation where ignoring it would be a good idea.

When I modify mtree.cfdg to change one of the calls to rule WL to WLb I get the error message
Shape with no rules encountered: WLb.
Is this the situation that you are talking about?

Yes, that's what I was talking about. I just noticed I was still running 2.2beta3 (v9). Using the final release (v10) it works like you describe. Sorry for the confusion.

I thought I was running the final 2.2 version, since beta3's output said "cfdg - 2.2(v9)"...

I'll be more careful with future beta releases.
