> Some of the Rebol documentation mentions "hidden" object values, and says
to see the Rebol user's guide for more information. However, looking at the
/core user's guide (2.2.0), I can't find any mention of how to make a hidden
object value. Is this possible, and if so, how?
Here's some stuff you might not know about objects:
>> o: make object! [
[ A: 1
[ B: 2
[ C: 3
[ ]
>> first o
== [self A B C]
>> second o
== [
make object! [
A: 1
B: 2
C: 3
] 1 2 3]
By using 'first and 'second, you can access parts of the object.
For hiding stuff in objects, you can use a technique like this:
>> oh/f
** Script Error: Invalid path value: f.
** Where: oh/f
>> oh: make object! [
[ F: none
[ use [A B] [
[ A: "AAAA"
[ B: "BBBB"
[ set 'F func [] [print [A B]]
[ ]
[ ]
>> probe oh
make object! [
F: func [][print [A B]]
]
>> oh/f
AAAA BBBB
BUT! The first use of 'recycle (or allowing the Rebol Garbage Collector to
function) and then issuing:
>> oh/f
crashes Rebol. Which is annoying. :-(
