[REBOL] Re: Namespaces for functions/some tips

From: tim::johnsons-web::com at: 28-Aug-2001 11:36

Hi Gregg: DISCLAIMER: I am not an advanced rebol programmer. If any "real" rebol find errors or omissions in the following, then it's to my benefit :>) Having said that: I'll share some of my approaches and caveats: 1)Build a block of system words NOTE: some will come from your user.r
>>all-rebol-words: first system/words
; now you have them in a block and you can print them, ; store them, whatever 2)Any time that you compose a word, check to see that it isn't a system word. I also highly recommend using the rebol function dictionary. 3)"Overloading": Let's say you're setting up an object with a method called "print". If you use 'print with the "print" method, the result will likely be a stack overflow resulting from recusion. You can "overload" this by using 'system/words/print. 4)Refinements: See above. And. If using refinements within an object. You can compose a block of the words in the object with something like this: Interpreter session follows:
>> do %cgilib.r ; load the object into memory >> cgi-words: first cgio ;build a block of object words
; now you've got a list of words that you can refer to by something like this: >> find cgi-words 'path-parts or just >> find first cgio 'path-parts Example: I've got object function member call 'hidden. In another function of the same object, I have a refinement called 'hidden. I use self/hidden to avoid the collision. OR I might want to chose a different strategy. We're getting a bit dicey here. 5)System words can be redefined like: sys-print: :print SCRIPT LIBRARY:; System Object Browser HTH Tim On Tue, Aug 28, 2001 at 10:36:02AM -0600, Gregg Irwin wrote:
