how to export a function from a context?

 [1/2] from: Patrick::Philipot::laposte::net at: 30-Dec-2003 21:58


Hi List As I was reading "Make-doc.r" from Carl Sassenrath, I came upon a construction I had not noticed before. Or perhaps, I had not noticed how important it was before. Nothing new for a lot of you, but ... I think it's cool to see some Rebol code once and a while on this list. 8< - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Rebol [ date: 30-12-2003 purpose: { FAQ Q - "how to export a function from a context?"

Hiya Patrick: Here's a different approach: Remove the assignment to 'private-room Now you have context [ a: b: 2 set 'public-fn func [][print [a]] ] At this time, 'public-fn is still 'public' but 'a, 'b are now 'hidden', inaccessible from the outside world. but of course, you can't make copies of the function. tj
