Hi!

How would I go about to getting a MiniD-table off the stack?

stackmanip.getTable does not seem to be accessible from outside the MiniD library, is this intentional or is there another API-call that I'm supposed to use? Smile


In any case, I love the language, it's so much sweeter than Lua.

/kw

[edit] (For now, I removed the package declaration in stackmanip.d and on a couple other places to get access to MDTable.data)

You don't get a reference to any of the reference types in the MiniD API. You just manipulate them on the stack. Getting direct pointers to the objects is dangerous, as they could be collected out from under you.

What do you want to do with the table? If you want to iterate over it, look at foreachLoop; if you want to just get an item out or put one in, look at idx/idxa; if you want to actually store a reference to the table in D code, use the reference mechanism (pushRef/removeRef, and there's also a helper class in minid.ex).

Ah! Now I get it. foreachLoop is exactly what I was looking for, missed that one.

Thanks for your response!
