[REBOL] Kicked of list / Empty lines

but there isn't any function called feedback, is there? You have to "do %feedback.r" imho Hi Pekr Yep, in 2.2 (which I have to keep around to do FTPg), you can just type 'feedback' ... I suspect 'do %feedback.r' was left out of rebol.r for later versions. A nitpicky little thing, but the FTP problem is a good deal more major. but, as they do say in Germany: REBOL ist Perl ohne die Komplikation. Which should be "REBOL is Perl without the complication," only when I translate it back into English, I get "REBOL is bubbles without the complication." From this I infer that Perl doesn't translate very well from system to system; which is why I use REBOL in the first place. Hey! It's gonna be an interesting day here. I see that already.g --Ralph

That's the IETF... the main rfc for e-mail is 822. There are other standards that go along with e-mail messages, like MIME, that are defined in other rfc's, however. I just looked on Google and found a good page for you. Check it out: http://www.imc.org/rfcs.html http://www.imc.org/rfcs.html#rfc822 is a shortcut to the specific section dealing with 822. If you've never looked at standards before, they take a little getting used to. If you're trying to write something to parse up e-mail in Rebol, your time would probably be better spent just looking at a lot of your e-mail and figuring out the format from there. Then if you really want to get precise go look at the standards. Hope this helps!

[REBOL] REBOL/Core 2.3 Released! Re:(2)
Ok, good info. Thanks Ralph. It has been so long since we released a Core, we knew that the chances were good that we might miss a few "small" items. But, now that you are ready to test experimental releases and our automated build post scripts allow us to release without swiping a minute from our critical product development schedules, you'll see things getting fixed much faster. For instance, the FTP problem below occurs over all our products, including Command and Serve, so it needs to get fixed very soon. You would see that fix in a 2.3.1 experimental that would automatically be posted. But, you would need to test it. So, get your testing resources organized!

On Wed, 28 Jun 2000, you wrote: YES That fixed it. Now, if I had only asked you first instead of all those other peopleg Good :). A word of explanation to everyone about this: FTP can be used in the following ways: - active mode, no proxy. (This is the default) - passive mode, no proxy. - active mode, SOCKS5. - passive mode, SOCKS5. - passive mode, SOCKS4. Note that the SOCKS4 protocol does not support incoming connections, so the combination "active mode, SOCKS4" is not possible. Up until REBOL/Core 2.2 "passive mode" would only be used if REBOL detected that "active mode" does not work with a user's setup (automatic fallback). This fallback still exists in Core 2.3, but experience shows that not all FTP servers support the automatic fallback (in particular FTP servers on Win-NT often do not support it because they do not detect "connection refused" errors), and sometimes SOCKS servers have problems with the fallback as well. As a workaround for these server bugs Core 2.3 also allows users to manually switch to passive mode by putting system/schemes/ftp/passive: true into user.r. That forces FTP to always use passive mode. One other enhancement in the FTP implementation from Core 2.2 to 2.3 was that Core 2.3 supports "active mode, SOCKS5". Core 2.2 did not support this, i.e. it always fell back to passive mode when SOCKS5 was used for FTP, which caused problems for some users. Core 2.3 now supports all possible combinations of proxy servers and active/passive modes for FTP. -- Holger Kruse [EMAIL PROTECTED]

[REBOL] a quine or two
Just for fun: here's one of my first little exercises to get to know REBOL better: a "quine". This is a program which prints out its own source code when you run it. Here was my first attempt: REBOL [ Title: "A simple REBOL quine" Author: "Jake Hamby" Email: [EMAIL PROTECTED] Date: 23-Jun-2000 File: %quine.r ] header: [ Title: "A simple REBOL quine" Author: "Jake Hamby" Email: [EMAIL PROTECTED] Date: 23-Jun-2000 File: %quine.r ] code: [ print ["REBOL" mold header] print ["header:" mold header] print ["code:" mold code] print "do code" ] do code Note the duplication of the contents of the REBOL block. Of course the program would have been much shorter had I left the REBOL block empty, but I wanted to be kosher and do things the right way. Also, it piqued my curiosity about whether or not I could get at the contents of the REBOL block from within my script. I discovered how to do it, and here's my second successful quine: REBOL [ Title: "A simple REBOL quine" Date: 23-Jun-2000 File: %quine2.r Author: "Jake Hamby" Email: [EMAIL PROTECTED] ] print-obj: func [x][ foreach word next first x [ val: get in x word if val [print rejoin ["" word ": " mold val]] ] ] code: [ print "REBOL [" print-obj system/script/header print ["]^/print-obj:" mold :print-obj] print ["code:" mold code] print "do code" ] do code I'd like to submit these to the script library, as well as to this page (http://www.nyx.net/~gthompso/quine.htm), a repository of quines in many different languages, but I wanted to see if anyone could do better first. One curious "feature" of REBOL I discovered while fooling around was that blocks of code can contain embedded newlines and other whitespace, which display when you print the code block, but are invisible when you manipulate it like a list. In other words, this: block: [ a b c ] and this: block: [a b c] are equivalent in every way that I can see, *except* when you print them. Similarly, I was unable to programmatically construct a block with embedded newlines, which might have been helpful to me for this exercise, but print-obj turned out to be so short that I guess it doesn't matter. It is a weird feature, though: I think REBOL's doing the Right Thing for readability, but it's curious that I can't get at the internal structure where this is stored. -Jake

This is great, thanks, and congrats to all the REBOL team... but g... I was going to use 'feedback' to report that FTP is still broken but it seems that 'feedback' itself now does not work. I get: feedback ** Script Error: feedback has no value. ** Where: feedback and the FTP error that has appeared in all REBOLs since 2.2 is still there: read ftp://ftp.abooks.com/ connecting to: ftp.abooks.com ** User Error: Server error: tcp 425 Can't build data connection: Connection refused.. ** Where: read ftp://ftp.abooks.com/ This latter is a bit critical for us here to get working again.

brett, after you complete the form and agreement (if you wish to), the script will take you to platforms.html where you'll find the 2.3 versions available. Let me know if you have any further problems. dan At 10:46 AM 6/29/00 +1000, you wrote: REBOL/Core is available for download at http://www.rebol.com/downloads.html and No it aint.

[REBOL] [ANN] 2KB News Reader 0.1.1 Re:(3)
Howdy, Ryan, and others interested in REBOL's nntp.r: NNTP servers lie. They tell you a range of numbers of articles that MAY be there. They may well not be there, though. It's a funny thing. The only way to really get the true number of articles in a newsgroup is to get the headers for each article (which over a 22kb modem 'aint always a good idea). NNTP.r, as it is, also provides the optional NNTP "XHDR" command which lets you quickly download just the subject lines (or any other given header field: from, to, keywords, etc..) of all the headers in the group. Having all the subject lines, you can then know for sure (unless some of those articles expire while you are reading) the count of articles in a newsgroup. One of the things NNTP does when it connects to a news server is determine if it can do XHDR. Interactively you can ask an open news port what it can do by inserting [help] into the port. Here's how you can determine non-interactively if the server you are talking to has XHDR: np: open news://news.somewhere found? find np/handler/commands 'xhdr Using XHDR you can do something like the following: np: open news://news.somewhere set [total start end] insert np [count from "alt.test"] x-mids: rejoin ["Message-ID " start "-" end] message-ids: insert np [xhdr x-mids from "alt.test" please] ;- please is optional :) The XHDR command gives you back a big string in a block. Yes, that is a little odd (XHDR was added at the last minute just to help aspiring news bot writers, if you want to know!). The string you will find in the block has the number of each article followed by the message id. It's trivial to parse the string and it'll allow you to ask for individual articles by their message-ids in order. There's examples of getting articles by message id in the NNTP.r howto. Using XHDR, you'll have an efficient way of obtaining true newsgroup ordering with no gaps (for news severs that support the feature ... If they don't well, you probably have to fall back on getting all the message headers in a group if you want to insure total ordering... that's what Forte' free agent does!!). Boy, nntp.r really is in need of an update. Looking at NNTP.r it's doing all sorts of dialecting things by hand that would be a lot easier to do today in modern REBOL with things like parse block. The whole thing could be shrunk by at least a half. So many things rattling around on our overly loaded wagon trains... :-) Hope that info may be useful on your projects. -jeff As for the message count, that seems screwed up, too, because I always end up reading fewer messages than what the nntp.r returns. I'm not sure if trying to fix this would be more than just butting heads with nntp.r which may have some issues. Pretty impressive. It's about time someone made some public use of NNTP.r. I found one problem, it either reports the wrong number of messages available or else it can't always find the next message. After 3 or so messages, if I press "n" for next message, I just get the instructions again for each time I press "n". Cheers, Allen K
[REBOL] [ANN] 2KB News Reader 0.1.1 Re:(4)
Thanks for the input, Jeff. I'll work on updating my news reader with x-hdr functions. Yes, news servers do return very strange information. They are definitely part of the 'old Internet' when things were rather rough around the edges. Boy, nntp.r really is in need of an update.

[REBOL] [ANN] 2KB News Reader 0.1.1 Re:(2)
I played around a bit. It seems when the nntp.r checks for messages associated with a newsgroup, it also includes messages which have "expired." This accounts for the "non-existant" messages for when you choose "N" for next message and you see nothing but the options again. I ran into a series of these messages, perhaps a half-dozen or more before the header and text of a message finally appeared again.

[REBOL] Password ask/hide in view?
With core there is "pass: ask/hide" for hiding the typed password. Is there something like that in view? The code below I used in view to have a popup box to enter user name and password. Can you hide the typed in text for the password field? Is there a better way? button 40.40.250 300x24 "Login First Please" [ inform layout [ backdrop 200.60.60 text "User Name" pf1: field 100x24 [ user: pf1/text ] text "Password" pf2: field 100x24 [ pass: pf2/text ] button "Close" [ ftpaddress: join ftp:// [ user ":" pass "@domain.com.au/public_html/log.txt" ] emailaddress: to-email join user "@domain.com.au" hide-popup ] ]; end of inform Regards: Greg Schwarzõ¿õ¬ ~Email - [EMAIL PROTECTED]
