Considéré par beaucoup de personnes comme un avantage concurrentiel, REBOL souffre d'un gros défaut de communication. Il y a une sorte d'omerta sur ce dernier.

Néanmoins, de nombreuses sociétés françaises et internationales utilisent REBOL sans vouloir communiquer dessus.

Nous essayerons de briser les tabous...

En attendant, voici les témoignages publiés en anglais sur le site reboltutorial.com

JSON had a lot of influences on its design. It didn’t just come out of my head. It’s based on a lot of things that I had observed over the years.

The first – maybe the greatest – influence was Lisp, John McCarthy’s work out of MIT in 1958. Lisp … was really powerful, and syntactically almost nothing, but it was kind of visually confusing because it’s tons and tons of nested parentheses.

The thing that was brilliant about Lisp was it used exactly the same representation for programs and data. Originally, the idea was that you would have programs that could act on themselves as data, and do interesting things.

Another influence was Rebol. Rebol’s a more modern language, but with some very similar ideas to Lisp, in that it’s all built upon a representation of data which is then executable as programs. But it’s a much richer thing syntactically. Rebol is a brilliant language, and it’s a shame it’s not more popular, because it deserves to be.

gregoryblogREBOL is a strange beast. When I first looked at it years ago I didn’t like it much, and I think that’s because I didn’t get it. Why do all variables seem to be global? How come there’s no module system? And so on.

But then I delved deeper. I discovered that one of REBOL’s great strengths (and weaknesses) is that it allows you to roll your own module system any way you like. It doesn’t prescribe how you ought to do any of this. Now that I have a strong understanding of advanced REBOL concepts like contexts and “Bindology” it all makes sense to me.

Because REBOL is designed for “PITS” (programming in the small), it does take a (very tiny) bit more effort to achieve things like encapsulation. (The REBOL philosophy, I think, is that when you’re writing small, disposable scripts, it’s not that important to worry about things like scope. (I disagree, but don’t find it to be a major problem.)

Fortunately it looks like REBOL 3 will address some of this. I’m looking forward to it immensely.

brianwittiblogThis is unusual. I’ve come across the first language that I don’t want to tell you about. I don’t know why I want to keep REBOL a secret. It has been very useful even in the limited roles that I have given it so far. The language is consistent and pleasant to work with. It has a richness of datatypes that just can’t be matched by other languages. The GUI library, View, is surprisingly straightforward for simple tasks, and there are excellent libraries like RebGUI to make it just as easy for more elaborate interfaces. Maybe I just want to think of REBOL as my secret weapon.

So what do I use REBOL for? Well, I spent about five minutes making a simple GUI application to help me balance my checkbook, for starters. I enter my transactions, it saves them and shows me my current balance (along with the record of previous transactions). It’s really nothing special, but it was disturbingly easy to create. Give REBOL a look-see. You might like it.

brianwittiblogAbout 25 years ago, I wrote my first computer program. Back then, BASIC was my language, and APPLE II was my platform. Since then, I’ve been studying computer programming on and off. I used dBase III+ and Clipper a lot when I was in high school.

After entering college, my major was computer science, which was fun for me. I learned C, x86 assembly language, C++, and Java.

When I was in the graduate school, we developed a Multimedia-on-Demand System in Java and won the Taiwan Java Cup Award, which made my life very different. I started teaching Java programming, giving speeches in Java conferences, and writing Java columns for IT magazines. Those jobs made me anxious for more information. I kept learning new technologies. “Saving for a rainy day,” I called it.

One day when I was in a local bookstore, a book caught my eyes. “REBOL: An Official Guide”. I had the cash in my pocket, so I bought it. This book was not an easy read for me, so I surfed on REBOL.com, and found the User’s Guide. After reading the User’s Guide, I kind of knew what REBOL was, but I didn’t have any chance to use it.

After a few years, I finally got a chance to use REBOL. One day in the morning, my ex-boss asked me to do something in one day. I decided not to do it in Java, since Java might take me a couple of days to do the job (even though I was good at Java). I used REBOL instead.

Guess what? I made it!

That’s amazing, considering I’d never used REBOL to do anything serious before and I didn’t know much about REBOL.

The experience was so good, that I bought a commercial copy of REBOL. I joined the AltME REBOL 3 world. I recommended REBOL to everyone I know. I taught REBOL in my Web Programming class in a college. I even put REBOL in my Java book (Well, I’d gone too far this time, since some readers didn’t understand why there was a REBOL section in a Java book).
