[REBOL] Re: Is Rebol OO?

From: jason:cunliffe:verizon at: 12-Jan-2004 17:17

Hi Gerard
Thanks I'll look into it.

There is no 'ultimate' - just keep learning keep growing keep changing.. But a high level book which discussed dialects would be a very interstnig thing. There are maybe some good Phd. thesis papers on the subject.

It fills in nice learning space bewteen mailing lists and elsewhere. That's one reason I think Vanilla is a natural fit for beginner. It icombines wiki wiht blog. And beacuase it in rebol very motivating to learn hands-on as needs emerge. In fact virtually all my Rebol experience is based on hacking aroudn Vanilla. Nothing sophisticated compared to people here, but satisfying useful and motivating. I owe you a post about Vanilla from discussion many days back. Will try to complete it this evening.

E:/DOCUMENTS/Gerard/credit card Orders/Alibris/ Well yeah it is annoying. Rebol and Python both have their own consistent intenal syntax. But it strikes me they shoul dbe smart enough to just check for the path syntax of the platform being used and then accept and convert to the internal. . I imagine such functions have been written many times over already by people.

And its one of the reasons I am big fan of Jabber because its presence mechanism makes it ideal transport for connecting collaborative apps like this. I want the user interface elements to be both control and display devices, capable of changing state when send or receive events. Of course Rebol/View can be good for that too. Personally I just find Flash is much more sophisticated and fun for that kind of gui development. I don't know how far the calendar component of IOS went. Perhaps it has what you want already in it ? Generally dialects and local uses of parse seem to emerge from some direct need. Some job grows really repetitious or lengthy. So a dialect can help simplify the code keep focus to the task at hand. Beyond that is the idea of hidden smarts, where they can embed logic and contextual behavior hiding the guts from the casual use. Extreme example was already provided: Computer do [what I want] Life do [what I need] not [what I want] etc.. If I understand correctly Rebol dialects are a *much* kinder version of what XSLT does. - Jason
