[REBOL] script not terminating, continues to replicate Re:(2)
A) You are not using a REBOL/view to serve this cgi, yes? I am using /Core 2.3 for Solaris on Sparc. B) You are using an expired experimental? It is not an experimental version of /Core. So is the #! line pointing to the correct REBOL? Yes. The script is in the same directory as the binary. How is this invoked, through an IMG tag? The script is invoked using an exec statement which is invoked by an include statement. I see that it is ending with .cgi. Perhaps another copy of it is lying around in another directory getting invoked erroneously? nope.
[REBOL] script not terminating, continues to replicate Re:(4)
The strange thing about it is that I had been running the script for months without knowing it was causing any problem. The hosting service claims they had warned me about it before, but I cannot recall any prior communications. I was experiencing much heavier hit volumes when they decided to make me pull the script (since two of the major BeOS news sites are down and I am one of the last few standing until BeNews and BeGroovy come back online.) Perhaps the higher hit volumes just exacerbated the problem. So, this script had been working when tested? Adding QUIT to the end? The script as it appears to me, as a regular CGI, shouldn't behave that way, so I'd conjecture there's something about the SSI method that causing the problem. Wish I could be more helpful. -jeff
[REBOL] shifting characters in rejoin
I have created a function which returns something strange when I use
rejoin.
The function is called build-html.r which builds a markup statement.
Here is the console result. Notice the closing bracket for the opening

do %build-html.r
Script: "Untitled" (none)

[REBOL] distributed collaborative support application
Here's an idea for a breakthrough REBOL application (forgive me if this already exists, since I do not normally go shopping for these sorts of things): I work for a support services company and we use several tools to operate the support center. We have a problem tracking application which includes contact management and reporting features. We also use e-mail, of course, and the telephone. Increasingly, we are using chat programs to facilitate communications between our support desk and our escalation contacts. Imagine a support application which features the following: -problem tracking, including work history, problem coding, contact management, and reporting accessible through the LAN, WAN, and Internet -integrated e-mail functions -integrated chat functions -integrated file sharing functions to share documents with off-site or alternate-site technicians -CGI interface which allows field technicians to access and update problems from the field using a laptop or even a Palm device
[REBOL] What should we bake? Re:
With companies like Register.com enticing everyone and their brother, dog, and grandmother to "register" their own domain, there will be increased demand for simple Web site building solutions. Tools like Microsoft Front Page are not the answer because the user still needs to use FTP and to understand too many other things about building a Web site. It is not simple enough. The simplest Web site building solution is a server-side application with a Web-based control panel. My vision is the following... 1. A user goes to a page on the Web where they can use the Web site building tool. After selecting which site functionalities they would like to include, they enter their credit card number, etc., and then move on to the site building process. 2. The user chooses the overall structure and layout and design of the site from a set of templates. Each template has a set of major regions where the user can choose to "plug in" the elements of a Web page, including photographs, chat interfaces, tables of links, journals, diaries, etc., etc. 3. The user finishes and clicks "Done." When the user is building the site, the program behind the interface could be building a REBOL script which executes upon visiting the user's URL and dynamically builds the page. The script is built using REBOL "plug-ins," functions designed to display a specific site element or designed to call upon some other functionality. Of course, the application should be using Cascading Style Sheets for better style control and the application would have to be tested against multiple browsers in multiple environments for the most consistent rendering possible.
[REBOL] Some ideas to collaborative environments Re:
Question: Would it be better to use a central-server for the collaborative envrionment like "ICQ" or should we use a more decentralized approach. (E.g. by using IRC to find the other participants and then create direct connections?) Depends on how it would be used. If the application would be used as to create a sort of "ad hoc" collaborative environment, then the decentralized approach is appropriate. But if the application would be used to create planned environments, then a centralized approach is best. The application would be hosted by an Application Service Provider, which everyone with a big pipe wants to be nowadays. -Ryan
[REBOL] parse or Re:(7)
Joel-
Thanks for the parsing routine. There are still a few things about it
that I need to look at a few more times for me to understand it
perfectly, but I was able to make a re-usable function out of your
routine. (I also changed some of the 'words because I like my scripts
to read like "plain English.") The function follows...
REBOL []
parse-paragraphs: func [
"Parse a document into a block of paragraphs."
document [string!] "the document to be parsed"
][
paragraph-block: copy []
current-paragraph: copy ""
stopper: charset {.?!:}
non-stopper: complement stopper
fragment: copy ""
sent: [
copy fragment [any non-stopper stopper]
(append current-paragraph fragment)
[{^/} (append paragraph-block current-paragraph current-
paragraph: copy "")
|{"^/} (append paragraph-block append current-paragraph {"}
current-paragraph: copy "")
| none
]
]
paragraph: [
(paragraph-block: copy [] current-paragraph: copy "")
any sent end
(if 0 length? current-paragraph [append paragraph-block
current-paragraph])
]
parse/all document paragraph
paragraph-block
]
To make up for my omission (and my lack of time/energy last night),
the following is a scheme for using parse to attack the paragraphing
problem you posted. I know it doesn't handle every possible case, but I
think it can be generalized in a fairly obvious way.
Enjoy!

[REBOL] The Industry Needs REBOL But Thinks it Wants Perl Re:(7)
How did you handle unruly students typing out of turn? (assuming there may have been unruly students. Trolls are always possible.) The possibilities for a productive online classroom are increasing, even for those persons stuck with low bandwidth. On the BeOS, we have BeShare, which is a file-sharing program (similar to Napster, but for any kind of file) but it is also a chat room where you can see who is connected at all times. It is a great community building tool because people pop in all of the time with questions, which they get answered (or at least responded to) much more quickly than they could receive responses from an e-mail discussion list. Of course, there are coding projects going on at BeShare quit often and the file-sharing aspects of BeShare help out with that quite a bit. BTW, BeShare is open source as well as the server software called MUSCLE. So far, MUSCLE servers have been compiled for the BeOS, Linux, and FreeBSD. I may start a REBOL collaboration on BeShare some day to increase the interest in REBOL. I need to brush up on my own skills first, however. -Ryan I used to teach online during early 90's. I taught C/C++ courses at CALC (Computer Aided Learing Center) using Genie network (similar to AOL or Compuserve). We used Roundtable (similar to chat room) for our classes. At one time, we had 60 students attending one class. What a fun to see so many online at once. I instructed them to raise their hands by sending just an exclamation mark. That way I had a queue of students jotted down. Each student has a chance to ask the teach. I didn't give lectures but just answer questions students might raise during the classes. The "lectures" were given in form of written texts. They could download those notes weekly. I assigned them with weekly projects. I was able to evaluate and grade their programming skills by looking at their projects they developed with what they learned during the course. Textbooks was used for the classes. (I am not a tutorial writer.)
[REBOL] REALLY DISCOVER THE POWER OF REBOL Re:(3)
It is a strange beast, indeed. RT depends on developers to create applications to show that REBOL is a viable alternative. Meanwhile, developers of the open source persuasion see tractor application development as RT's responsibility, feeling REBOL itself could be maintained by the open source community. This argument seems to crop up in relation to all sorts of products nowadays. It seems "open source" as a marketing element is here to stay. Somehow products that are "open source" have become attractive to customers in the same way shampoos are attractive when they have not been tested on laboratory animals. Only time will tell whether or not open source software like operating systems and programming languages will become the standard vs. commercial, closed source options. I tend to think open source operating systems and programming languages WILL become the standard because of how we use them. Like electricity, gasoline, etc., they are becoming resources which need to be standardized. I see an inherent mistrust of closed source products amongst many developers because a closed source product can be taken away as quickly as it is given. It's kind of like not wanting to commit to a relationship with someone who hides things from you. This is how I perceive this behavior, at least. -Ryan Things like Javascript have splintered badly, but that's because they were not Open Source, and vendors implemented their own closed source in different ways. All that happens is that people like Elan, Gabrial, Lemir, and Joel don't waste time ruminating about how REBOL is implemented. Rather, they can contribute working code to the project. Carl would still control what goes into the kernal. But Carl doesn't want that to happen, and so it won't. Pity, because it might free up some of his developers to create real-life reference applications, and then maybe more people would put REBOL to work. -Ted.

[REBOL] parse or Re:(5)
I assumed that
this is NOT what you wanted, but rather you wanted to copy through
either {.^/} or {."^} WHICHEVER COMES NEXT. (Natural language
text munching is a real pain, speaking from personal experience! ;-)
Yes, this is what I was looking for. As someone who has never
parsed anything before using REBOL (there will be more like me!) the
parsing rules are confusing to read in the REBOL docs. My
inclination is to want to use a simple statement which will parse until
a set of characters is reached OR a different set of characters is
reached, whichever comes along first and next.
The strategies I've thought of (I don't have time to code, compare,
and recommend right at the moment) are:
1) Write more complicated parse rules, that either
1a) parse to newline, append the copied chunk to a paragraph
string under construction, then look at the tail end of
the last chunk to see whether it can be extended or whether
a new paragraph should be started (based on whether it
looked like the end of a sentence).
1b) parse to period, grab and append the next character if it
is a quotation mark, append to paragraph under construction, and
start a new paragraph if the next character is newline.
2) Use simpler parsing (break on newlines), then make a postpass
across the block of "lines", gluing back together wherever the
boundary isn't the end of a sentence.
You missed another option, which I had been using previously. Here
is the function:
breakdown-content: func [
"breakdown an e-mail content field into its parts"
msg [object!] "e-mail message"
][
article-info: msg/content
end-of-paragraph: rejoin [{.} newline]
replace/all article-info end-of-paragraph {.~}
content-parts: copy []
foreach part parse/all article-info {~} [ append content-parts
trim/lines part ]
]
In other words, replace all instances of a set of characters with a new
character that can be recognized later. The above example needs to
be fixed because it only replaces instances of {.^/} with "~" and I've
discovered the tilde is a bad choice, anyway. I need to also be able
to replace any set of characters you might find at the end of a
paragraph, including {."^/} and {!^/} and {?^/} and {:^/} and {...^/} and
I'm sure there are more.
I was hoping there would be a quick way to use parse instead of
replacing characters first and then parsing.

[REBOL] standard message object
I have some thoughts about creating a standard message object! and I would like to hear your input. Across the Internet, whether it be in e-mail, newsgroups, bulletin board systems, or Web pages, the most common form of communication is the message. Messages have common values, illustrated as follows: EMAIL - From: Subject: Content: NEWS From: Subject: Content: BULLETIN BOARD -- Author: Subject: Comment: NEWS STORY -- Byline: Headline: Body: ...and I'm sure there are more comparisons I cannot think of at the moment. Because of these similarities, I suggest that a standard message object! be developed so that information can easily be exchanged between mediums. Furthermore, functions should be developed for converting messages from the e-mail, news, etc., formats into the standard message object! and vice-versa. But what values should be included in the message object! ? A news posting, for example, may include the following headers... From Subject Date Newsgroups Path In-Reply-To Message-ID References MIME-Version Content-Type Lines NNTP-Posting-Host X-Trace NNTP-Posting-Date Organization Xref Followup-To Content-Transfer-Encoding X-Complaints-To X-Mailer X-Accept-Language Reply-To X-Newsreader X-Priority X-MSMail-Priority X-MimeOLE User-Agent X-Abuse-to X-Comments X-Anon X-Mail-To-News-Contact X-Mimeole X-Sender X-Server-Date X-MIMEOLE X-Abuse-Info X-Anon-1 X-Anon-2 X-No-Archive Sender While an e-mail message may include the following headers... Received Return-path To From Reply-To Date Subject Organization Message-Id X-REBOL MIME-Version Content-Type Precedence X-MindSpring-Loop Content-transfer-encoding Priority In-reply-to References X-mailer X-SELMA X-PMFLAGS Bulletin Board messages and News Articles have their own formats, as well. Is there a standard message object! that could be developed and re-used? For example... make object! [ Author: Date: Subject: Body: Message-ID: MIME-Version: Content-Type: Origin: ] Are more values than the above needed for a standard message object? -Ryan

[REBOL] linux help Re:(2)
I would LOVE to be able to install a "plain" Linux on my Dell Latitude 433MC 486/33 laptop, but I only have a floppy drive. I've looked for linux distributions which I can install from floppy, but it seems I can only find CD-ROMs. More than Linux, I'd like to put a BSD on the laptop, but again I can only find CD-ROMs. I am suspect of this "monkey" linux. Do you have other programs created on redhat that work fine on monkey? Making your own rescue disk from redhat or similar and putting rebol on it should prove to you that the problem isn't space or environment.

[REBOL] REBOL stand-alone applications? Re:
Hmm... Well, with /View, here is how you can make a "stand-alone" app for the BeOS... 1. give the script the #! /boot/home/config/bin/rebol shebang 2. make the script executable. 3. give the script a nice icon. 4. use PackageBuilder to have the following installed when the end user double-clicks on the .pkg file... executable script in /install_folder executable script in /boot/home/config/bin/ rebol in /boot/home/config/bin/ This installs the /View rebol binary alongside the executable rebol script in the bin/ directory. Now the script is executable from the commandline (just type the name of the script) or the script is executable like other applications in that you can double-click on its icon to launch it. I'm sure something similar can be accomplished on other platforms. Of course, it's not within the license to install /View for the end user. This is how it COULD be done. 8-) -Ryan 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

low tuple value of 0.0.0 instead of 1.1.1).

Making this change only made the slider /data value change from 0 to 1 when I move the slider and the /data value doesn't return to 0. Change: red: slider 10x259 [red/color: ... to: red: slider 10x259 0 [red/color: ... etc. That should do the job.

the tuple range from 0.0.0 to 255.255.255 instead of 1.1.1 to 255.255.255.
Also, the hex values returned have a similar problem, whereas #010101 is
the darkest value instead of #00. Also, you must slide all color bars
from their original position before clicking on a color frame or else the script
will return an error.

The isp and modem part I feel is not needed because some people would be on a LAN some with a modem attached, so for software to run on all pc's it should use the connection normally used. All that would be needed is "connect username:[EMAIL PROTECTED]" for connecting to restricted areas on the net because it would use the normaly user name/password to get on the net. Or "connect/dial username:[EMAIL PROTECTED] 5551212" for one computer to talk to the server (non internet).

[REBOL] adding data to hyperlinks, etc. Re:(2)
Is it possible to pass variables to a REBOL script via a hyperlink as such? http://www.rebol.com/cgi-bin/test.cgi?value1 The QUERY_STRING will then contain "value1" correct? as if I had submitted a form to the .cgi script? In the interim while I haven't received any responses, I thought of a third solution, albeit I don't like it. The third solution is to have each news article rendered within its own form and to have its own submit button. The form can carry the article's reference number via the cgi object. This is probably the easiest solution, but I can't stand the thought of having so many submit buttons on a news headlines page. Perhaps I'll change the value of the submit button to be "!" so that it doesn't take up so much space. Otherwise, if anyone has an answer to my previous question I'm all ears. 8-) -Ryan Hello. Before I progress any further, I need some advice. With my script News Site, the script saves news articles as object expressions and loads them into memory before rendering a page based on the values in the objects. One of the object values is a reference number to differentiate the object from all others (since the objects are only object expressions they are assigned to object words upon loading.) The next feature I want to add is a commenting system. I want the reader to be able to click on a hyperlink for "comments" which will then execute a .cgi script. The .cgi script will then render a page including all of the comments people have posted in regards to the news article in question. The question I have is, how do I pass a value to a script from a hyperlink so that the script renders the correct set of comments? I have thought of another option, albeit more cumbersome. During the time the main script creates object expressions for the news articles themselves, the script could create a separate .cgi script just for that article. But how can I write a script to a directory and then make the script executable all at the same time? I'm thinking the web server will see the .cgi extension and assign it executable status, but I'm not sure that is always the case. I hope you're understanding what I am writing. Your help is much appreciated. -Ryan

Think of all the serial devices hanging off the end of PCs that need monitoring in real time. Given that I just "discovered" (thanks ddj) Rebol perhaps there is something I am missing?

[REBOL] benchmarking (teeny-bits-of-time/2 ) Re:(3)
I thought using a counting expression would be a simple way to benchmark a system. My results are disturbing, however. Consider my original expression: forever [ t: now c: 1 while [ now = t ][ c: c + 1 ] print c c: copy [] ] Here are the results of running the expression on an Intel Celeron 333MHz workstation running Windows NT 4 (66MHz bus) with Pegasus and Microsoft Excel both open at the same time: 37594 37261 37103 37313 37555 37551 37274 37472 37563 37195 37539 37556 37496 37579 37386 37540 37108 Now here are the results of running the expression on a dual Intel Celeron 433MHz machine (66MHz bus) running BeOS 5 Pro (with no additional applications open): 11607 11652 11649 11630 11713 11682 11595 11606 11538 11745 11693 11529 11456 11444 As you can see, the expression counted many more times-per-second on Windows NT 4 than on BeOS 5 Pro. In fact, REBOL on Windows NT 4 counted more than three times as high per-second than REBOL on BeOS 5 Pro. This is despite the fact BeOS 5 Pro was running on twice the hardware and then some. Examination: REBOL does not seem to utilize both processors simultaneously, instead it seems to alternate their use, which means the processors lose their cache information each time. Perhaps the REBOL for BeOS binary is three times as slow as the binary for Windows NT? I used Carl's expression... t: now/time n: 1 while [n 100] [n: n + 1] n / third (now/time - t) and here are the results: The Windows NT machine returned a result of 500,000 The BeOS 5 Pro machine (dual processors) returned a result of 250,000 I posted these results to the beusertalk mailing list and the response was that the compiler used to create the BeOS binary must be far less superior than the compiler used to create the Windows NT binary (which compiler did RT use for this? I know BeOS R5 ships with a much better compiler than previous IDEs.) The response also was that perhaps the code used to create the BeOS binary requires some optimization. The BeOS seems to return much better benchmark results using other criteria (e.g. OpenGL frame rates) than using a REBOL counting expression as a benchmark. Is the code for the BeOS binary written to take advantage of BeOS' multithreadedness and for SMP? I gather from watching my Pulse meter while running the REBOL expression that REBOL does not utilize SMP like it could on the BeOS. -Ryan Also, WRT calling NOW in a loop. Note that it is very expensive on some systems! Compare the loop timing on this line to that below that calls NOW. It takes nearly 10 times longer (under WinNT) if you call NOW. Ryan's loop should be up in the 40 range rather than 38000. Amazing, isn't it. t: now/time n: 1 while [n 100] [n: n + 1] n / third (now/time - t) -Carl

[REBOL] teeny bits of time Re:(2)
I'm using /Core 2.2 on both Windows NT and BeOS 5 x86 and nope, such a feature doesn't exist. I'm sure there are hurdles in getting exact measurements of time in less than seconds. If it would be possible to run a continuous REBOL routine in the background while continuing to execute REBOL scripts in the foreground, then I suppose you could call upon a word that returns an approximate sub-second length of time (most likely represented as an estimated fraction of a second instead of an exact measurement in milliseconds.) Depending on the workload of the cpu at any given time, this estimated fraction of a second may be based on a different denominator. Any other thoughts on this? I REALLY would like to be able to call upon fractions of a second in REBOL. -Ryan Ryan, Have you tried the view version ... maybe its there. -Larry [EMAIL PROTECTED] wrote: Wouldn't this be cool? current-time: now/time == 20:37:33 print current-time/hour 20 print current-time/minute 37 print current-time/second 33 print current-time/millisecond 14 print current-time/microsecond 57 print current-time/nanosecond 98 Any idea if this would even be possible? -Ryan

Here are the results of running the expression on an Intel Celeron 333MHz workstation running Windows NT 4 (bear in mind the first number returned is the remaining number of times the expression can count from 1 within the second the expression begins): 2498 37594 37261 37103 37313 37555 37551 37274 37472 37563 37195 37539 37556 37496 37579 37386 37540 37108 I guess this is a REBOL benchmarking expression of sorts. If you could run this expression continuously while running other REBOL scripts--and if you could call the count from within the expression using another REBOL script running in parallel--you could create a fraction of a second based on the average count total during a specified period of time. For example, you call 'c from the expression when 'c = 2000. Perhaps the average number of counts during the previous 10 seconds was 37,501 counts per second. Then the fraction would be .053331 seconds. REBOL could return a special 'now of now == 19-Jun-2000/18:20:44.053331-5:00 or current-time: now/time == 18:20:44.053331-5:00 Then you have your milliseconds, microseconds, and nanoseconds as follows: print current-time/second 44 print current-time/millisecond 5 print current-time/microsecond 33 print current-time/nanosecond 31 Of course, this is a very imprecise way of measuring sub-second intervals in REBOL. Any suggestions on how this might be implemented? -Ryan

[REBOL] web apps Re:
I was the one who inquired about the spellchecker. This application you found is very cool. Check out... http://www.spellchecker.net/features/textbox.htm You can link the spellchecker to any textbox. A REBOL version would be great because REBOL would be able to accomplish something similar without Javascript (useful for Palm devices, etc.) a few months ago someone asked for a spell checker, just found http://www.spellchecker.net - using a javascript file and a script (perl). would rebol be an interesting choice for this task?
[REBOL] An appeal to keep /Core Re:(3)
One of the things that always amazes people is how powerful /Core is despite how small the binary is. I think /Core needs to stay around because we will be looking to put messaging language into smaller and smaller devices and time goes by. Put /Core on a watch or in a medical device which swims in the bloodstream and sends messages back to a computer via wireless. Keep /Core around, for sure, and work to make it SMALLER for gosh sakes. It's just my opinion, and that of many others so it seems, that /Core oughta stay around. This does not mean that we do not want /View or /Command or any of the others (we do, we do!)... It just means that /Core is the perfect entry level point for REBOL and we hope that ever-so-easy-to-open portal remains in place.
[REBOL] REBOL and the unix shell Re:(3)
Hey, combine these articles with the script library, online documentation, news headlines, links, discussion board, a REBOL store (hey, who doesn't want a t-shirt, anyway?) and an open-source project area and you have a very cool resource. 8-) My real hope is that if I get a bunch of these articles together, other people would be interested in contributing some domain specific articles of their own to the collection. REBOL is used for a universe of tasks, and various people out there know the complete ins and outs of doing a particular task with REBOL. IMHO, their specialized REBOL knowledge should be recorded and shared with the rest of the community.
[REBOL] /view and the Web Re:(5)
No. I am thinking of the possibility of creating interactive Web pages using /view . I agree with Ryan, I dont see an end to /Core any time soon. I can see it getting stale, kind of like it is right now. Ryan, are you thinking of making a web browser using view? --Ryan [EMAIL PROTECTED] wrote: I can't see /core being "discontinued" except perhaps being replaced by /command . Perhaps /core is the enticement for /command . I am beginning to use core as a CGI workhorse for me (and I hope Carl continues with it, despite some evidence to the contrary in this list).
[REBOL] %detach.r Re:(3)
The following accomplishes the feat of copying the encoded image into a 'word and appending the string value with the proper brackets and "64#" designation.
stuff: msg/content
imagecode: copy []
if find/any stuff {image/jpeg} [parse/all stuff [thru {base64^/^/} copy text
thru {==} (append imagecode text)]]
insert imagecode "64#{" append imagecode "}"
write/binary %image.jpg imagecode
But the %image.jpg does not display correctly. What is it I need to know about base64 encoding to make sure that "write/binary" produces the correct result? Following is the result of
>> print imagecode

[REBOL] RSS, ICE, etc. (was group projects ) Re:(4)
Wow, I wasn't aware of Rich Site Summary (RSS) and Information and Content Exchange (ICE) standards before you mentioned this. The RSS method seems fairly simple, see... http://www.publishing.about.com/arts/publishing/library/blrss.htm While the ICE method seems more involved. Since you know more about the trends, which method do you recommend? I definitely would like to make the creation of a syndication file automatic within my project, but is RSS enough to offer potential clients? -Ryan Ryan... interesting stuff. You might want to check out all the work going on on XML/RSS/RDF/ICE syndication of headlines, XML-RPC and similar interfaces to syndication, etc. Full disclosure: my current company (cf. http://www.clickfeed.com ) has built an aggregation personalization / syndication framework for news with customized delivery using some of this same tech. It's a rich space, but needs standard interfaces. (Data transport is there, but the whole inbound side of things --- the push side, ala your Scoop --- is totally open.) jb [EMAIL PROTECTED] wrote: I'm interested in reading more about your vision. OK, here goes... I have currently laid plans to develop (and have begun developing) a suite of REBOL applications I have dubbed "The News Mail." The first in the series is an application called "The Headlines" which allows you to update the news headlines on a web site by simply sending an e-mail to a POP account. Why this functionality? For the sake of simplicity and accessibility. If you can update the news headlines on a web site by simply sending an e-mail, you can update the site from any number of e-mail clients, including those found on Palm devices, etc., so long as they are sending text/plain output (a more complicated parsing routine for RTF and HTML could be developed, as well.) The original, functioning version of "The Headlines" can be seen at http://www.fargonews.com where all of the headlines and article content appearing there has been updated via e-mail. My original script is called Scoop and can be downloaded at http://www.bebits.com/bob/3796/Scoop_1.0.zip I have completely re-written Scoop to be object-oriented, with individual news articles saved as objects which are loaded and handled later. All local settings are saved in a config file which is loaded first. The new version of Scoop is called "The Headlines" and the input portion is functional, while the text/html output needs to be broken off and developed as a separate application. The look of the text/html output is controlled by a cascading stylesheet which can be replaced by any other stylesheet using the same class names. Other ideas for "The News Mail" suite... -"The Links" for updating web site links via e-mail. -"The Ads" for updating banner advertisements via e-mail. -Commenting System, Classified Ad System (through CGI.) -Offer access to "The Headlines," "The Links," and "The Ads" through a CGI interface, as well. Ulimately, I'm looking to offer a Web business customer the opportunity to manage a news-oriented Web site without having to actually manage a web space. The customer will be able to manage the site through e-mail and Web-based forms. Setup time for the Web developer will be minimal: perhaps 30 minutes tops to customize the config file which controls the various REBOL applications in the suite. OK, so I've spilled my guts. Input, anyone? I'd like to know what people think about saving data as objects vs. saving data in database format. I'm assuming saving the data as objects makes the data more versatile. Thanks. -Ryan
[REBOL] group projects Re:(2)
It would be very cool to have some sort of group project site exclusively for REBOL. It would, of course, have to be scripted in REBOL. 8-) -Ryan A while back I toyed around with the notion of setting up a SourceForge style development site / community called "Webol.org" devoted to web application development using Rebol. If there's any interest in this, I can cobble together those notes and huck them up to the list or something. I'd be happy to provide the server space, but time isn't as free as I wanted it to be to work much on this... jb [EMAIL PROTECTED] wrote: I checked SourceForge and there isn't a single REBOL project listed. I have started a project myself and I have a vision, but I'm not sure whether SourceForge is the place to post it. Does anyone have plans for a REBOL site where persons can work together on REBOL projects? Is anyone interested in working on group projects? My sense is that the REBOL community is largely made up of developers who may be averse to group projects for fear that someone else may make money off of their ideas. Or maybe the REBOL community is so small that group projects haven't surfaced yet. I'd like to know your throughts on this. Ryan Christiansen Web Developer

[REBOL] detach.r
I am trying to detach an attachment (.jpg image) from an e-mail using the
script detach.r from the REBOL script library. Unfortunately, I am getting an
error, as follows...
detach msg/content
starting decoding process...
** Script Error: find expected series argument of type
: series port bitset.
** Where: if boundary: find/tail boundary {boundary="}
In the 'msg/content, there is no {boundary="} statement. Instead, there is a {--
Message-Boundary-11825} statement.
My question is: Is my Pegasus e-mail client sending some non-standard
"boundary" indicator? Is there any way to set this up so that the script will
work with most e-mail clients?
I can't find any other information in the REBOL docs or examples about
detaching e-mail attachments.
Thanks. Detailed msg/content and detach.r script information follows...
The msg/content looks as follows...

[REBOL] detach.r Re:(2)
Doing as you said overcame the problem of the function looking for a string!
instead of an object!
But...
detach msg

== none
Then I had to change
if boundary: find/tail boundary {boundary="}
to
if boundary: find/tail boundary {boundary=}
Then...
do %detach.r
Script: "Save email attachments to disk" (9-Jun-1999)
detach msg

Boundary string: Message-Boundary-1182

** Script Error: copy expected range argument of type: number series

Again, is the {boundary=} statement sent by Pegasus causing problems?
Take another look at the detach function. It expects the wohle email
message as text, including all the headers and everything. If you already
have the imported email object, you should be able to change the top of
the detach func to look like this:
detach: func [
{Takes in the whole email text and returns a block of filenames
and decoded base64 attachments present in the email}
mail [object!]
][
headers: mail
print "Starting decoding process..."
boundary: headers/content-type
.. rest of script...
and then call 'detach msg'
Sterling
I am trying to detach an attachment (.jpg image) from an e-mail using
the script detach.r from the REBOL script library. Unfortunately, I am
getting an error, as follows...
detach msg/content
starting decoding process...
** Script Error: find expected series argument of type
: series port bitset.
** Where: if boundary: find/tail boundary {boundary="}
In the 'msg/content, there is no {boundary="} statement. Instead, there
is a {-- Message-Boundary-11825} statement.
My question is: Is my Pegasus e-mail client sending some non-standard
"boundary" indicator? Is there any way to set this up so that the script
will work with most e-mail clients?
I can't find any other information in the REBOL docs or examples about
detaching e-mail attachments.
Thanks. Detailed msg/content and detach.r script information follows...
The msg/content looks as follows...

[REBOL] multi-tasking? Re:
If you do the following... do %script.r do %script2.r do %script3.r The scripts will execute in succession, but when they complete is up to the processor, RAM, hard drive, etc. This is how I understand it, anyway, because you are essentially mult- tasking within a single task, which is the REBOL application itself. Hi i'm writting to ask if it's possible to launch other scripts from a single script, but, without having to wait for each script to end before the next one can starts. thanks. timmy
[REBOL] set in object 'variable string Re:(2)
This is not an option. The documentation says you can "set in" new values to an existing object. But it is not working on /core for WinNT. Is the documentation incorrect or... may have to create another object? test-obj-2: make test-object [ y: "another string" ]
[REBOL] set in object 'variable string Re:(2)
The documentation is very poor concerning objects because there is a paragragh in the objects documentation as follows... The in function can also be used to set words: set in fred 'balance $20.00 print fred/balance $20.00 This paragraph is telling me I can set a new value into an existing object using the following syntax... set in object 'word value But obviously it doesn't work. The following does work, however, and thank you for the help. -Ryan ob1: make object! [x: "hello"] ob1: make ob1 [y: "world"] probe ob1 make object! [ x: "hello" y: "world" ]
[REBOL] set in object variable string Re:(3)
Ah, yes, I see. Too bad it doesn't work the other way, too! 8-) -Ryan It works if the word already exists in the object. Mike. test-object: make object! [x: "string"] print test-object/x string set in test-object 'x "new value" == "new value" print test-object/x new value
[REBOL] set in object 'variable string Re:(4)
"set" means "assign a value to," as when you declare a variable and then assign it a value. You were trying to assign a value to a variable that did not exist. Yes, but that IS the purpose of "set" set 'test-word "test words" == "test words" print test-word test words I have just assigned a value to a variable that previously did not exist. Thus, reading that I can... set in object 'word value makes perfect sense.

Where can I find more info on this? Your last point could be solved by the Cachè-Database which already uses objects for storing information. They call it postrelational database or multidimensional database.
[REBOL] crlf and newline (was Re: parsing by period and newline)
Thank you for this help.
Another question: I understand the difference between "newline" and "crlf"
but...
1. Is "crlf" a replacement for "newline newline" ?
2. Is "crlf" a Windows convention vs. *nix?
3. When should I be concerned to make sure I parse by "crlf" as well as
"newline"?
Hello [EMAIL PROTECTED]!
On 05-Giu-00, you wrote:
n end-of-paragraph: rejoin [{.} newline]
n ;does not work as I desire (i.e. parsing ONLY by instances of
n a period followed by a newline character.) Using a charset
When you use PARSE in that way, it splits the string at each
occurrence of any character in the second string; that is, the
first string is split each time a #"." is found, and each time a
newline is found. PARSE will split the string twice if the two
characters are found in sequence.
Anyway, a working solution is:
breakdown-content: func [
"breakdown an e-mail content field into its parts"
msg [object!] "e-mail message"
][
article-info: msg/content
content-parts: copy []
parse/all article-info [
some [copy part thru ".^/" (append content-parts part)]
; this is if you need to keep the last paragraph
; even if it is not ended by . and newline
[end | copy part to end (append content-parts part)]
]
]
Using your example I get:
content-parts
== ["^/^/First paragraph here.^/" "^/Then a second paragraph. Another
sentence.^/" "^/A final paragraph.^/" "^/"]
If you want to get rid of the newlines, you can use TRIM/LINES,
changing:
append content-parts part
to:
append content-parts trim/lines part
This way I get:
content-parts
== ["First paragraph here." "Then a second paragraph. Another sentence."
"A final paragraph." ""]

Gabriele.

[REBOL] group projects
I checked SourceForge and there isn't a single REBOL project listed. I have started a project myself and I have a vision, but I'm not sure whether SourceForge is the place to post it. Does anyone have plans for a REBOL site where persons can work together on REBOL projects? Is anyone interested in working on group projects? My sense is that the REBOL community is largely made up of developers who may be averse to group projects for fear that someone else may make money off of their ideas. Or maybe the REBOL community is so small that group projects haven't surfaced yet. I'd like to know your throughts on this. Ryan Christiansen Web Developer

[REBOL] variable not local?
Loading the following functions and then using the expression...

produces too many values for the "body" word in the resultant object...

Somehow, the "content-parts" variable in the breakdown-content function
carries over from one operation to a second operation. Why is this
happening?
Thanks.

[REBOL] Re: no exact naming rules (was [REBOL] AW: [REBOL] Syntax highlighting for GoldED)
I am very much a fan of text editors with good GUIs combined with good functionality. I use text editors extensively for HTML and for CGI scripting (but I am not a C++ programmer.) I would very much like to see a text editor with the following: two "drop zones" where you can drag and drop new words that should be highlighted in a script. One drop zone would be for words universal to the type of file you are writing in (.r, .html, .pl) and the other drop zone would be for words local to the specific file you are writing. After dragging a new word to the drop zone, you would choose the type of highlighting preferred from a drop-down menu. What do you think? There isn't. And I doubtit's possible to write a good syntax highlighting module for rebol at all. In most languages there are exact naming rules, e.g. in my favourite language E: first two literals of word are upper case-constant first two literals of word are lowercase , not ending in a ( -variable first literal upper case, second one lower case - standard E function or a system function ... But with rebol ? imagine the syntax parser finds a word like Öffne_Datei : what is it ? A variable, a function ?
[REBOL] Re: data storage (was: [REBOL] rebol ecommerce site Re:(3))
This subject brings something else to mind I would like to share... I am looking forward to REBOL/Command in the hopes that the BeOS version will support read/write access to extended BeOS File System attributes. Extended BFS attributes are a simple, reliable way to store and retrieve data in fast, robust, journaled file system. Within the next few weeks or months, the new BeOS kernel-based networking environment dubbed "BONE" is expected to be released in a point release upgrade for the BeOS. BONE is rumored to be just as robust and stable as Linux. Meanwhile, Apache 2.0 when completed will support the BeOS. I was wondering if your content is store in a database or flat file. How did you deal with REBOL's data limitations?

[REBOL] two-digit return of now switches
Is there any way to make REBOL return a two-digit /month or /day or /hour or /minute
or /second ?
I have a file-naming scheme which names files based on the date and time they are
created in the following format...
20001225122345.html
The above file was named at 12:23:45 p.m. on Dec. 25, 2000
But unfortunately REBOL returns a single digit for a /day for example if the day is
less than 10. This is not satisfactory since I want to be able to find my newest
document at the tail of the directory.
Here is the naming scheme I am currently using...
current-time: now/time
