Then something cool happened. I launched the application from the /view console and then opened a /core console to send data to the port specified by the /view app. The /view layout did not change until I clicked on the window. Upon doing so, a little animated REBOL logo appeared in the lower right-hand corner of the layout. Is this logo supposed to be appearing in every layout?

[REBOL] Bug in either clean-script.r or the parser. Re:
Hi Brett,
I've had a few problems occasionally with this script too. I tried hard to
track down the exact condition that caused the bug, but couldn't. I've also
noted that if run a few times in the same session it can accumulate indents.
Send your bug report direct to the author..

Subject: [REBOL] Bug in either clean-script.r or the parser.
I've been using clean-script heavily recently, and have now tripped over
the
following problem.
clean-script mangles the attached script.
Specifically it creates an unmatched "(" for the following line. In other
tests it could be a new "[".
table-start: [text-line (emitter/start-table trim text) newline]
The thing is it handles earlier such lines correctly, which leads me to
think about the parser.
I've think I've narrowed it down to the script not "consuming" the first
"["
for this line. Instead load/next gets and it will return a block value.
I tried removing some lines before this line and the error moved. Same for
when you add extra lines - BUT they have to be of the same type not just
any
old line.
Any ideas?
Thanks.
Brett.

I was considering moving to Forth, but a few days ago discovered REBOL may I ask firstly, I find the sample View text-edit.r is very slow taking 0.5 secs to accept a char, have I made a error in my install ,something not set correctly ? A full screen Rebol editor would be very useful. There is still some optimising to be done in the View beta. The speed of a large editable area is one one of them. Currently, if you reduce the area e.g halve the height, you will get a more reasonable edit speed. This might be an indicator of the improvement to come, in the experimental version of BeOS I find that a large screen edit is faster than std native BeOS editor. So I'm waiting to see if this improvement will be the same across all platforms with the next beta release. Cheers, Allen K

Subject: [REBOL] bug ?
Difference is a high-level function that returns the differences
between two datasets. But datasets do not exist in Rebol
(they're not a datatype), so difference accepts any series including
strings. However, when you use it on the content of two files (read
%file), you get a strange result :
difference file1 file2
== {:"39%.@{}!(^^4567)~}
From the Core release docs addendum, DIFFERENCE renamed EXCLUDE, though
DIFFERENCE is retained as a synonym for EXCLUDE.
Why do you say it won't work? It appears to be correctly returning only the
different characters as would be expected when dealing with a string. What
it returns depends on what the series is made up of.
difference "ABCDEFG" "ABCDEFGH"
==H
difference [1 2 3 4] [1 2 3 4 5 8]
== [5 8]
difference ["the" "cat" "sat"] ["the" "cat" "sat" "on" "the" "mat"]
== ["on" "mat"]

[REBOL] /content-type and rebol/core (was %detach.r) Re:(2)
Hi Ryan,
Actually it is a custom BeOS MIME content subtype that seems to be the
problem.

Subject: [REBOL] /content-type and rebol/core (was Re: %detach.r)
OK. The newer version of %detach.r worked fine with the Windows NT/
Pegasus e-mail message. But it is having trouble with the BeOS R5 Pro/
BeMail e-mail message.
Here are the /content-type and /content results of using 'probe to view
email objects as REBOL sees them. As you can see, the "boundary="
statement as read by REBOL/core produces something different than what
the e-mail header declares.
Here is the /content-type as produced by 'probe
Content-Type: "multipart/mixed; boundary=_--_BeOS.rmp.96"
Rather than parse using the inbuilt parser. Could you post the header in
plain text?
Would need to see this to find out why the parser is getting it wrong. It
may be that
BeOS is not breaking the line length and that a mail gateway is being
'helpful' by trimming it
---
From what I have seen in the message it seems to indicate that BeOs is using
a custom defined multipart sub type. producing a nested form of
multipart/mixed, which is not wrong, but I would be surprised if the parser
did handle it.
From the RFC---
multipart -- data consisting of multiple parts of
independent data types. Four initial subtypes
are defined, including the primary "mixed"
subtype, "alternative" for representing the same
data in multiple formats, "parallel" for parts
intended to be viewed simultaneously, and "digest"
for multipart entities in which each part is of
type "message".
-
But if you look at the Boundary you will see that it is not a standard
format but rather custom content type. That of multipart/x-bfile
So it looks like you will have write some changes to detatch.r to handle
this BeOs specific subtype.
multipart/x-bfile. If you send the same message and content from both email
clients, save the message as plain text and examine the contents and the
differences you should be able to see what steps need to be added to handle
this content subtype in detach.r.
Cheers,
Allen K
Here is the actual beginning of the email /content as produced by
'probe
Content: {This is a multi-part message in MIME format.
--_--_BeOS.rmp.960760927_--_
Content-Type: multipart/x-bfile;
^-boundary="++BFile111399423249++"
As you can see, the parsing routine within REBOL/core found the first
line in /content which contains "--" and copies the line past the "--"
and only up to the "6" and then quit, as follows...
_--_BeOS.rmp.96
Any suggestions? Does REBOL/core for BeOS need to be fixed? Or is Be,
Inc., not adhering to some e-mail message standard?

Hi Allen, Ryan
Allen, good catch there. But there may also be a problem with finding the
start of the base64. Looking at an e-mail in my pop mailbox:
--=_NextPart_000_0025_01BFD481.83702DE0
Content-Type: image/jpeg;
name="bay.jpg"
Content-Transfer-Encoding: base64

...
Won't the appearance of the Content-Disposition line cause the code to
fail
on this e-mail?
Are the blank lines just before and after the base64 required by the MIME
standard?
Perhaps best to find "image/jpeg" and then find the blank line before the
start of the base64 with "^-^-" ?
Can we find the end of the base64 by looking for the blank line after?
I suppose, we would like to get the image file name as well?
Sorry for the stupid questions, but I don't know much about this.
Cheers
Larry
You are right Larry, there will also be a problem with finding the start,
after finding base64 should find "^/^/" before copying. There should be at
least one empty line between a mime content header and its content.
Something like this perhaps. (not tested).
parse/all email-contents [thru {base64^/} to "^/^/" copy text to {--}
(append

Hi all, I've written a little Rebol app to learn on, which, on running, simply reads my pop email box and displays the from, subject and date fields in a list. Now, the window does not show until the network read is done. Because the network read is slow, the window does not appear straight away. In fact the Rebol icon does not appear on the task bar (Windows NT 4) until the window is created. In my Powerbuilder work, I strike the same problem when a user opens a window that must show the results of a database read. To the user this looks like the application is slow. What is normally done in Powerbuilder is to declare a post-open event for the window. Then in the code that runs at window-open, POST a message to the window's event queue. So that after the window opens and is painted (and anything else is done) the system comes to the post-open event which will then do the database call. The end result is that windows open almost instantaneously (so the user sees that it is working) and then the information fills down the page. I would like to achieve something similiar with my little learning rebol app. My guess is that the same technique could possibly be used, but I'm not sure. Or others may have a different technique. I've considered opening a "dummy" initial window that then calls the other stuff , but I used to do that stuff years ago in more primitive (user interface days) so I would like something a little more neat and elegant :) Brett.

The rate setting working as a substitute for my POST event command very smart. Still, a 1x1 image... shades of HTML solutions :) Yes and no.. It is just an inherited style, image had all the other facets and feel, I wanted without having to write an entire face for it A lot of the VID components are inherited from others. Image is inherited by all these Progress, List, Anim, Frame, Box, Backdrop. Here is a rough layout VID styles indicating inheritence. FACE -SENSOR -IMAGE --Progress --List --Anim --Panel --Frame --Box --Backdrop -BUTTON --Check ---Radio --Arrow --Toggle --Rotary --Choice -TEXT --Label --Title ---Subtitle -FIELD --Area -SLIDER I wonder about few things though. When does the count down for rate start? Observasional guess work here, and it would be good to confirm. I believe it is triggered after the show is called on that face. Show is called inside the 'view function. The beauty of this is that layouts can be created before time and have their own individual load events, that won't trigger until they are shown. You can always add a counter with switch [ 'time [counter: counter + 1 if (counter 10) [rate: 0 engage: none do action] ; may have to change the order of these.. ] Will this change in a different Rebol version? Will the "user experience" be the same under different platforms? Do I really need the overhead (even if small) of an graphical element for what is really an event? Good questions, The overhead is minor, however to avoid adding it, the other way would be to insert an event to the top level events using insert-event. Which is not really a solution for the non technical VID user. My aim was to provide a simple reusable plugin solution to the problem from a VID point of view, though the technique can be used in any face. If you are using faces then you have absolute control, investigate the insert-event-func. I know we have a 'quit event, I wonder if there is a 'start event? Nevertheless. Thank you. It will do this job. Brett. Glad it helped.. I'm sure better ideas will come, it is the nature of progress.. Cheers, Allen K

[REBOL] http authorisation - how? Solution Re:(3)
Anton, Brian
I've found the problem.
Does your password or user-id contain a space?
Example from RFC2617
!--StartFragment--To receive authorization, the client sends the userid
and password,
separated by a single colon (":") character, within a base64 [7]
encoded string in the credentials.
basic-credentials = base64-user-pass
base64-user-pass = base64 [4] encoding of user-pass,
except not limited to 76 char/line
user-pass = userid ":" password
userid = *TEXT excluding ":"
password= *TEXT
Userids might be case sensitive.
If the user agent wishes to send the userid "Aladdin" and password
"open sesame", it would use the following header field:
Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
OK lets try this..
enbase join "Aladdin" [":" "open sesame"]
== "QWxhZGRpbjpvcGVuIHNlc2FtZQ=="
Cool that creates the correct one, but the problem we have is
when we include the it as part of the URL. The space is URL encoded.
(confirmed from reading a trace)
http://Alladin:[EMAIL PROTECTED]/file
So Rebol will send the wrong code..
enbase join "Aladdin" [":" "open%20sesame"]
== "QWxhZGRpbjpvcGVuJTIwc2VzYW1l"
And hence we get the dreaded 401 Not Authorised Error
So if you have this problem then use the following method to access the page
instead.
print read [
scheme: 'http
host: "fortytheives.com"
user: "Alladin"
pass: "open sesame"
path: "path/to/file/"
target: "file.ext"
]
I'm sending in a feedback on this..
Cheers,
Allen K

[REBOL] How does Rebol earn it's stripes? Re:
- Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, May 31, 2000 9:38 PM Subject: [REBOL] How does Rebol earn it's stripes? When I first read on Rebol's site that the distinction between code and data is blurred I cheered. I looked at the language constructs and thought that looks like some of my psuedo code. But then hmm...now what? I've been trying to figure out what Rebol's niche is(/are). Well for me the niche for Rebol is anywhere that has a hard drive and an internet connection. It is a really time saver, virtually any web or file task that needs automation. It is described as a messaging language. Between what and what? I can see how flexible it is. Less clear is the readability of the code I've seen. Readability of the code? That is a very subjective thing and depends on what other languages you are used to. One of the beauties to me of Rebol is that you can use white space where ever you want. (Anyone tried Clarion? If the line doesn't start in the correct column it complains!) But I find Rebol very easy to read and very English like. Like any code it can be complex or simple depending on the task. Rebol just makes more complex tasks simpler. I would really appreciate it if people could tell me what applications of Rebol they have made (or dreamt of) that clearly show Rebol (with it's announced features) as being a better choice than a general purpose language for those applications. I've written an email processor/server for message archiving. The whole thing barely takes up 20k and will work equally well when the client changes OS platforms. For the future, I see Rebol on pocket pcs, with numerous travelling salesman friendly apps. I see smart documents, that a client can run from a floppy, view a catalog and place orders. And when View is complete I see a nice cross platform spreadsheet app. Putting my crystal ball away now. Cheers, Allen K I've got so many scripts on my harddrive, that I've had to write another script to index them :-)

After viewing your counter I got an idea you might like. You can have your REBOL counter preprocess your web page--much like the way PHP or SSI does. Have it parse your web page looking for a special text like ~counter. Once this text is found it would replace it with the actual count. This way would let you use your favorite html editor to create and edit the page, and still have an easy to create program. You could also use tags like REBOL-counter, just 12345, or whatever sequence you feel appropriate. This could be useful for doing quotes of the day, random jokes, time and date, and all that other fun stuff. This would only add about 3 or 4 more lines to your existing counter script. Hint: use the replace function. You will also need to tell the webserver that your printing html by first printing "Content-type: text/html^(0A)^(0A)". Best of all, it would count everytime. --Ryan

[REBOL] getting web pages via script Re:
Hi Jason,
** Access Error: Cannot open

** Where: write file read site/:file
The reason why you are getting the error is because the file name you are
trying to save it under contains illegal characters. The "?" is an illegal
character in Windows (and some other platforms) filenames.
You could use 'trim/with to remove the illegal chars.
foreach file files [write trim/with copy file "?" read site/:file]
Or you could use 'replace if you prefer, to subsitute another value
foreach file files [write replace copy file "?" "$" read site/:file]

This doesn't solve/answer all your questions, but it should get you on the
way. The following code will
parse through page with all the courses listed on it and pull out all the

Then the second part of the script, reads/saves these pages into the

%courses/californiacreek etc., the code also shows simple error handling
using 'try [], which is needed as the bowen is a dead link
This should give you a taster of how powerful the command parse is. If you
read through the parse docs at http://www.rebol.com/users/parintro.html it
should help you solve the rest of your requirements.

Subject: [REBOL] Text to CW !!!
Hi,
I saw a perl script in USENET news that coded text to CW -alphabets,
the author of script challenged others to do the same with a shorter
program. I thought to do it in REBOL. Here it is, much shorter than
the original perl -script, that was actually very badly written, but
unfortunately a bit longer than the shortest (and very unreadable)
perl script. This script is a bit broken (because I tried to take
every byte off that I could). And almost unreadable. It is certainly
not a good example how one should program in REBOL. I post it
here just because there might be some interested in it. Here it comes
(about 210 bytes :)
REBOL[]foreach c system/script/args[s: copy{ }x: index?
find{etianmsurwdkgohvfüläpjbxcyzqö*54*3***2***16***7***8*90}c
until[s:
head insert s either odd? x["."]["-"](x: to-integer x - 1 / 2) = 0]prin
s]
And a little more readable version:
REBOL[]
foreach char system/script/args [
str: copy " "
pos: index? find
"etianmsurwdkgohvfüläpjbxcyzqö*54*3***2***16***7***8*90"
char
until [
str: head insert str either odd? pos ["."]["-"]
(pos: to-integer pos - 1 / 2) = 0
]
prin str
]
It is supposed to be used from the commandline, but it is easy to
alter do otherwise. I'll repeat this, if you want to use this code
snippet in your program do yourself a favor and fix it, currently it
is hmm... feature rich :) It does not like spaces in input and
also unknown characters produce a crash.
Have fun,

[REBOL] REBOL for DOS Re:(5)

What other "simple" OSes are left? Linux? Not all that easy. Upcoming Neutrino? Standalone Amiga/Elate? Maybe DOS is ugly OS, but it is lightweight and boots fast. Still not sure RT will reconsider REBOL DOS release though ... Have you tried BeOS? Powerful as Linux, GUI interface, et al. Take a test drive :-) www.be.com free.be.com Well, it was not my intention to miss BeOS, as in real - I am going to give it a try as I have some good references to it. Just waiting for new hw. However, it's still gui system, occupying some XX MBs on your hd. I had some "pocket" server appliances in mind :-) Doesn't BeOs Personal weigh in at about 500mb? Whew! John Hi John, Boes File download is about 40 mb. But Beos needs 500mb space to create a virtual partition (ie a 500 meg windows file that contains the beos file system). Rebol on Beos runs in the telnet app If we are talking space then Beos uses a lot compared to Dos. (There is also supposed to be an embedded Beos version available) The only thing that makes Beos comparable to DOS really is how fast it boots. Beos boots up and is ready to use in under 20 seconds on my system. That's pretty amazing for a gui system (though my emulated Amiga boots just as fast, after waiting 3+ minutes for windows ;) Cheers, Allen K
[REBOL] System object documentation Re:
Hi Tim, Best way to learn what is in the system object, is to use Bo's browse-system.r script from Rebol.org archives. http://www.rebol.org/utility/browse-system.r. Many of the entries in the system can also be accessed through mezzanine functions. e.g source what-dir what-dir: func [ "Prints the active directory path" ][system/script/path ] The note on not using source system is in the FAQ. http://www.rebol.com/faq.html From the FAQ " Q. I find that when I type SOURCE SYSTEM, SOURCE REBOL, or PRINT SYSTEM, the computer will lock up. Why? A. Viewing the system object should only be done with care. Future revisions of the system object are going to change, therefore, use the mezzanine level functions to access system object information when possible. With that said, here is an example of viewing the system object: print mold first system [self version product words options user script console ports network schemes error standard] print system/product Core WARNING: DO NOT enter 'print mold second system' or 'print mold system' since this will cause the interpreter to hang.

[REBOL] Updated Replace
Hi All,
Heres an updated version of 'replace from Bo, that fixes an issue with
'replace and tags. (where the correct length of the tag was not taken into
account during a replace), that I sent in as a feedback issue.
I have been testing it and seems to be working properly. If you find any
problems please let [EMAIL PROTECTED] know.
If there is no problem then this updated version should (hopefully) end up
in the next core release. This updated 'replace also has a case refinement
An example of the problem that was identified in the current rebol/core
'replace
replace "This is a string with a tag in it" tag tag2
== "This is a string with a tag2g in it"
or
replace "This is a string with a tag in it" tag ""
== "This is a string with a g in it"

[REBOL] getting Rebol OK Re:(4)
What with infinite loops? "rebol.exe" says Windows? my 95 can stop rebol's with the task-manager, but for instance old textpad can't do it (maybe textpads fault)? And all are named REBOL.. Could there be a timeout which triggers like escape? Volker Hi Volker, This is kind of off target here, but.. The method below would solve that problem in rebol/view. It ensures that processes don't keep running in the task manager after the window is closed for a rebol/view script that has an infinite loop. Hopefully the event scheme could be added to rebol/core too. or Perhaps some of the rebol/core gurus have similar solution for rebol/core? event-port: open [scheme: 'event] forever [ ; do stuff... ; do more stuff wait event-port ; since time events are always firing it won't have to wait long. event: first event-port if event/type = 'quit [break] do event ] close event-port ; end of script..

Subject: [REBOL] Associative Arrays in Rebol? Re:(2)
In article [EMAIL PROTECTED], you wrote:
I think select and paths should come close to what you're asking:
select [ a "this is a" b "this is b" ] 'a
== "this is a"
I'll have to ponder that for a while but my first thought
is that doing it that way would make it difficult to
populate it from a data file of arbitrary data.
Here is a snipit from the Awk doc's that explains what I'm
after.
http://www.gnu.org/manual/gawk-3.0.3/html_chapter/gawk_12.html
Arrays in awk superficially resemble arrays in other
programming languages; but there are fundamental
differences. In awk, you don't need to specify the size of
an array before you start to use it. Additionally, any
number or string in awk may be used as an array index, not
just consecutive integers.
In most other languages, you have to declare an array and
specify how many elements or components it contains. In such
languages, the declaration causes a contiguous block of
memory to be allocated for that many elements. An index in
the array usually must be a positive integer; for example,
the index zero specifies the first element in the array,
which is actually stored at the beginning of the block of
memory. Index one specifies the second element, which is
stored in memory right after the first element, and so on.
It is impossible to add more elements to the array, because
it has room for only as many elements as you declared. (Some
languages allow arbitrary starting and ending indices, e.g.,
`15 .. 27', but the size of the array is still fixed when
the array is declared.)
A contiguous array of four elements might look like this,
conceptually, if the element values are eight, "foo", "" and
30:
Only the values are stored; the indices are implicit from
the order of the values. Eight is the value at index zero,
because eight appears in the position with zero elements
before it.
Arrays in awk are different: they are associative. This
means that each array is a collection of pairs: an index,
and its corresponding array element value:
Element 4 Value 30
Element 2 Value "foo"
Element 1 Value 8
Element 3 Value ""
We have shown the pairs in jumbled order because their order
is irrelevant.
One advantage of associative arrays is that new pairs can be
added at any time. For example, suppose we add to the above
array a tenth element whose value is "number ten". The
result is this...

Brad Emerson Hi Brad, A couple of ideas... db: [ "book" "The Hobbit" "book" "The Stand" "candy" "Mars Bar" "candy" "MM" ] foreach [category item] db [ if category = "book" [print item] ] Or you could look at rearanging the way you store your data, so that items are stored under their categories. db: [ book ["The Hobbit" "The Stand"] candy ["Mars Bar" "MM"] ] foreach item db/book [print item] foreach item db/candy [print item] or category: 'book foreach item db/:category [print item] Cheers Allen K

Subject: [REBOL] Parse questions ??
Hello All,
I have a file consisting of lines in the following format:
"23123+34234+234234-23423+3-"
ie, n digits followed by a sign etc etc.
The only way i've been able to extract the data into a series is to do two
replaces, replacing "+" by "+ " and "-" by "- " and then parsing it using
the space as a delimiter. I can't use the sign as a delimiter because that
only returns the value and not the sign.
My first question is, should parse allow the delimited character to be
optionally returned by way of a refinement?? In this case the sign is a
delimiter but also an integral part of the data.
Hi Mike,
You are using parse in its simplist form, as just a split function,
whenever you need more from it, you can create your own parse rules.
See attached script, and the 'parse topics in the docs
The other problem i had was once i had the data in the form "123+", i
wasn't able to convert it to decimal, because the sign was at the end and
not the beginning, so i had to write code to move it.
Do people think that decimal and integer should be modified to allow for a
optional sign at the end??
I admit I don't see this form very often, so I would not see any need for it
to be built in,
but others may. It only takes one or two lines to convert this format to an
integer, it doesn't
take much to make your own converter. (see attached script)
Cheers,
Allen K

[REBOL] HELP!! Inserting text problems Re:(3)
Hi, Here is a different approach, using Replace. Not as efficient, but simple to use. marker: copy "Insert Here" new-text: copy "Insert This" replace/all page marker new-text or if you need to preserve the marker text marker: copy "Insert Here" new-text: copy "Insert This" replace/all page marker join marker new-text Cheers Allen K - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, February 12, 2000 2:48 AM Subject: [REBOL] [REBOL]HELP!!
