Questions about Rev/Transcript vs. other toolkits

[Chipp Walters]

Kevin,

Welcome to the best kept secret for many of us professional developers. 
I've yet to find something I can't build using RR. See below for some 
thoughts and answers.

I'm primarily a PC programmer, but have 'dabbled' some in Applescript. 
Just like Applescript uses an 'english-like' syntax, so does Revolution. 
The language is quite robust, in fact, rarely have I ever had to go 
outside the language for both Mac and PC applications. I've created a 
neat little image app called "ButtonGadget" (www.buttongadget.com) using 
RR with no externals. Took me only a couple of weeks to develop.

I probably am not the best person to ask, but my partner is a seasoned C 
programmer and has used most of the toolkits you've talked about. He 
tells me I can build apps an order of magnitude faster than the fastest 
C programmers he knows. He also is a big fan of RR, and Altuit (our 
company) builds externals for it as well. (See 
http://www.altuit.com/webs/altuit2/RunRev/default.htm)

As you probably already know, QT is even more expensive than Rev. Also, 
Rev has an Express product which is very affordable. Actually, one of 
the biggest advantages Rev has going for it, is this list. It's VERY 
active and both newbies and advanced users are welcome :-)

Dan Shafer is a big python nut, and perhaps he'll chime in here. I doubt 
you can create the types of interfaces in Python as you can in Rev. In 
fact, I believe Dan has written books on both Python and Rev and he 
could give you some advice...(He's currently mostly using Rev these days).

You can purchase the Reference Manuals from Rev direct...I did. They 
make for great 'bedtime reading' but you'll probably also want to buy 
Dan's book as well. It's great for those just getting started. You can 
find it on the RR site.
