[REBOL] New Amiga support?
Hi Rebols, I just noticed a new line in experimental releases: Group System-name Hardware Type TaoElate/intent VP tar.gz There are no releases by now, but does this mean that REBOL will run on the new Amiga? It would certainly be a reason to buy one ;-) -- Michal Kracik
[REBOL] web stuff
Unfortunately, I have been unable to participate much on the list recently. I finally got my book Rebol the Official Guide and it looks really great so far. They even talk about strange context behavior right at the start! That's a good sign that it's not just for dummies. The installation/unzip instructions are brutally detailed, though. I have been trying out some Load Testing software for our web app, because of course it works fine here but when 200+ users hit our software simultaneously, it slows down and then sometimes just hangs IIS permanently. I tried finding some products on the web that do load testing but one didn't work for our app and the other, Astra, costs $30,000+ for about 250+ simultaneous virtual user load emulation. That's not within my present budget. So I thought that Rebol might make a very good toolkit for doing Load Testing. I thought why not record with the http proxy in Rebol, and then play it back later with a vuser emulator also made with Rebol. Of course it would have to be able to handle session ids for IIS (temporary cookie). By the way, the cookies-client.r is giving me trouble. there are documentation mistakes, redundancies, and inflexible code, and it doesn't fetch binary files like .jpg properly because of mishandling of cr lf chars, etc. - does anybody have a proper version that works or does anybody want to have a go at improving the blasted thing? For instance, what the heck is the actual purpose of cookie-data2? Why are there two and not many (a block)? Where is an actual example of use of each of these? Is the cookie stuff supposed to be built into Rebol, or do you have to get down and dirty with the http protocol internals? Finally, when I was testing the proxy.r program, I noticed that it seemed to work for simple pages with few graphics, but the minute I access a web-page with several icons as gifs or jpgs, such as our main menu, most of these images are not getting retrieved from the server. I think the connections are being closed as soon as the browser or the server creates an event that takes it out of waiting on the connection, but the data retrieved is length zero. The program then closes it's side of the connection and also closes its proxy partner connection. Let's hear it for the coitus interruptus jokes. I don't know if keep-alive stuff needs to be added to proxy.r to be a proper proxy or what, but if I can't fix that I really can't use Rebol for Load Testing, which would be an aweful shame. Any help would be much appreciated!! Thanks! -Galt

Hi n.p. you wrote: Now that you've got my wheels spinning, would it be possible to develop a real-time chat application in REBOL? I just sent an email to the Ally list in the thread module that includes a rudimentary chat-type server. With a few modifications, it should do something like this. To collect single characters from the console you can use something like Cal Dixon's code for his rem editor (which I recommend, btw. A well-designed and very useful and surprisingly stable beta version): port: open/binary [ scheme: 'console ] get-key: does [ wait port to-string copy/part port 1 ] All you need to do is open an additional tcp port add code that inserts the value returned by get-key into the tcp port. On the client side you open a tcp port and use prin to output the character that was received on the tcp input port.

Web page contained something like rebol:// So, I don't know if remote module creation is clear concept - will have to think about it, as if that should be consistent, what about other "make"s? Some time ago someone proposed rebol ram-disk equivalent. I even sent request for 'make refinement /external e.g. 'ram 'ram-disk (being schemes). So I though general mechanism for sharing stuff over network would be great. Even hooking rebols thru system objects could be great.

[REBOL] Order of arguments to common words Re:
Interesting idea, Keith. Hi, I'm just wondering why this design choice was made: for pretty much any word that finds or picks, etc. a location out of a series, for example: print find "here and now" "and" blk: [red 123 green 456 blue 789] print select blk 'red 123 str: "REBOL" print pick str 2 E (all examples from the dictionary) the series is the first argument, and the index or the thing to find is the second argument. I'm just wondering why this is, because it seems like this makes it more confusing to string them together. For instance, with the way it is now, you would write something like: "skip skip [a b c d e] 2 2", which to make clearer with parentheses would be (skip (skip [a b c d e] 2) 2). How come it was chosen for it to be this way rather than being able to do "skip 2 skip 2 [a b c d e]", if the arguments were reversed? Just looking for some insight :) Thanks! Keith
[REBOL] REBOL stand-alone applications?
I would like to be able to put together an client side standalone application that uses REBOL - but I do not want to require the user to download the REBOL and see the scripts that make up the application. Is it possible to create a REBOL app that completely encapsulates the REBOL engine and hides the script(s) And if so, how? - Scanzoni

[REBOL] REBOL chat server Re:

I'm talking about sending ASCII AS IT IS TYPED to a port which is sent via tcp/ip to a terminal window (or a view layout?) The ASCII then appears in real-time, backspaces and all, on the receiving end. Check out multisession.r (on rebol.org, I think). It needs some work to be a "chat server" but it has all of the network and i/o basic functionality for it. I've been slack in working on my server lately, but I've achieved chat server status (at the least). I actually wanted buffered i/o (line not sent until the user presses return) and couldn't get rebol to do it automatically, so I had to scan the input for eol manually. I could have just as easily sent out the characters as they were typed. Np. Now, to do this with a REBOL/View client featuring an input window and an output window, would be even cooler. I'm using telnet to connect to my server. Is it possible? Certainly :) - Michael Jelinek
[REBOL] Re:Trapping errors? - Not like the book says?
Hi Doug,
Why don't you try it this way:
if error? error: try [send [EMAIL PROTECTED] {test} true ][
log-event/error system/script/header/file "error" (disarm error)
]
SEND doesn't return a value, so TRY doesn't return one either. As a
result all the set-word error: sees is the unset! value, which produces
the error. If you add 'true to the end of the try block, that
ensures you'll have some value to set 'error to. Here's an illustration
with PRINT, another function that returns no value.
type? try [print "hello"]
hello
== unset!
error? try [print "hello"]; ERROR? doesn't mind unset!
hello
== false
error? error: try [print "hello"] ; but error: can't stand it
hello
** Script Error: error needs a value.
** Where: error? error: try [print "hello"]
error? error: try [print "hello" true] ; give it TRUE to keep it happy
hello
== false
See you,
Eric
[REBOL] web stuff Re:
Just replying to one bit. By the way, the cookies-client.r is giving me trouble. there are documentation mistakes, redundancies, and inflexible code, and it doesn't fetch binary files like .jpg properly because of mishandling of cr lf chars, etc. - does anybody have a proper version that works or does anybody want to have a go at improving the blasted thing?

Is the cookie stuff supposed to be built into Rebol, or do you have to get down and dirty with the http protocol internals? I hope that cookies will be supported in Rebol. I think that cookies-client.r is a bit too low-level. One way I have seen it done (WebL) is having a cookie database built into the language, which by default makes cookies transparent to the programmer. It also allows the programmer to manage cookie databases. Something similar would no go astray here. I was going to give this method a go, but became entangled in uncertainty as to what is the real cookie spec. actually is. Then I just got sidetracked.
[REBOL] Rebol Config/INI File Difficulty Re:(2)
Thanks for the 'compose lesson. I've never had to use it. I can get something close to what I want, but I still am having trouble getting the following to work. Here is one file %in.dat: REBOL [] [ ss [ item1 "hello" item2 "goodbye" ] other [ n "bad" ] ] Fine. Now a console session sprops: do %in.dat == [ ss [ item1 "hello" item2 "goodbye" ] other [ n "bad" ] ] save/header %out.dat sprops [] Here is what %out.dat then contains: REBOL [] ss [ item1 "hello" item2 "goodbye" ] other [ n "bad" ] Not what I want. I want (expect) to see exactly what is in the file %in.dat. So I say, OK, use compose/deep to enclose the thing in a block. The following: save/header %out.dat compose/deep [(sprops)] [] gives the same %out.dat as before. And this: save/header %out.dat compose/deep [[(sprops)]] [] makes %out.dat look like the following: REBOL [] [[ ss [ item1 "hello" item2 "goodbye" ] other [ n "bad" ]]] As you can see there are is now an extra enclosing block instead of just one!!! How do I save sprops, which has the exact form I want, to %out.dat so it looks exactly like %in.dat??? TIA, Rodney
