[REBOL] Re: How to capture keyboard tab when typing in an 'area?
Hello, and welcome to Obscure Undocumented Features Of REBOL!! Today's question comes from Alan who is trying to make sense of some of the confusing behaviors of VID styles. Congratulations Alan, your question was chosen at random from the bottom of the email box. Change the flags in the face: view layout [ field area with [flags: [field]] field ] The two fields will tab between each other but the area will not and the tabs will go into the area. Your question rated a fun-factor of 8.7 and therefore you get a bonus question answered for you... here it is: Question: So what are the available flags?? Answer: It's a secret! Just kidding. ;) The flags you can use are: field -- behave like a standard field meaning that text is highlited upon selection and the clear-fields function will clear the text in this field tabbed -- tab and return will move the focus to the next valid face return -- return key activiates the action block of the face Well Alan, thank you for playing Obscure Undocumented Features Of REBOL!! You'll alsso be getting a copy of our home game, a bag of mismatched socks, and a copy of our fake studio audience applause on CD. We hope to see you here next time on OUFOR. Sterling Newton for OUFOR, saying If you don't play, you can't win! Help! How do I change the feel (or whatever) for an 'area so that when I enter a tab from the keyboard, a tab is entered into the area/text.

[REBOL] Re: Hide a face inside its action event?
It all depends o nwhen you do the hide. The problem you are running into is that the face is reshown automatically to display the change in the face as you release the mouse button. If you hide it on the 'up event then it should hide just fine. Example: view layout [ button hide feel [ engage: func [f a e] [if a = 'up [hide f]] ] ] Sterling Is it possible to hide a face when you're responding to an action for that face? E.g. clicking a button performs some actions, one of which is to hide the button itself. I can't seem to make it work. Other faces hide just fine, but not the one that is engaged. Example: view layout [button hide [hide face]] I'd like to avoide setting flags and having another face responding to time events just to do this, but if I have to...

[REBOL] Re: BNF grammar of REBOL for code obfuscator
No need to PARSE it yourself. :)
REBOL knows all this stuff on it's own so let it do the work.
? load
...
REFINEMENTS:
/header -- Includes REBOL header object if present.
/next -- Load the next value only. Return block with value and new position.
/library -- Force file to be a dynamic library. (Command version)
/markup -- Convert HTML and XML to a block of tags and strings.
/all -- Load all values. Does not evaluate REBOL header.
Play around with load/header and load/next. The /all refinement is
recommended if you are working with an unknown script so that no
evaluation will happen.
To remove comments, just let REBOL remove them for you and try:
save %file2.r load %.file.r
I'm sure you'll get some more input on this from others too.

Hello REBOLers,
I would like to write a code obfuscator (C-ish intention, isn't it ;-)) ) for
REBOL. Tha main idea behind is to have a custom loader by
'COMPRESSing the program code and 'DECOMPRESS it on load, like this:
- the packager REBOL line:
write/binary %someprog.bin compress read %someprog.r
- the shell loader (WinDOS .BAT file):
rebol.exe -s --noinstall --do do decompress read/binary %%someprog.bin quit
To get the unnecessary overhead data out of the script I would like to
- strip the header to the simplest REBOL [] form
- extinct one-line and block comments
- reduce tabulation and blank lines to single whitespace
My first approach to detect the end of the REBOL header did not work:
I just cannot keep track of the nested block levels in parse rules :-(
I also stucked at detecting comment boundaries
- to detect one-line comments whether they are _real_ comments
or just ; characters buried within a string (both and {} delimited)
- detect 'COMMENT blocks (reprise of the previously mentioned
detection problem for nested blocks)
Do you have an exact BNF notation (or directly 'PARSE rules) of the
REBOL language ? I searched the library but even %color-code.r is very
spartanian and does not destructure a REBOL script this way (although
its syntax coloring purpose might have suggested so).
Thanx for your commitment of ideas!

[REBOL] Re: To do or not to do?
NOO There is always a way not to do strings. :) Think about it this way... what are you building in your string that can be done? Answer: REBOL code. Why does this work? type? 5-Nov-2001 or this? type? first [10] Answer: because REBOL understands REBOL. Now what's the difference between these two statements? a: print 10 b: [print 10] Not much. do a 10 do b 10 Great. So why do we want to use the second one? Well, check this out. type? second a char! type? second b integer! How about this? find a integer! == none find b integer! [10] This is useful stuff! You can change your code far easier this way than with strings. REBOL knows what you're dealing with and can help you out! Now, the super-quick translation of your code below. I re-arranged the blocks so that the replacement would be simple but you could just as easily do it using COMPOSE or BIND to get it done. I use the word 'item in the block to be the replacement instead of * since words are meant to be symbols and that's exactly what we need. Rules: [ [0 length? to-string item] No data [date? item] Bad date [greater? now/date item - 14] Too old [specialcheck item] Not special ] ;; prepare data field ;; == RawValue: 5-12-2001 ;; bad date in this example Loadedvalue: if error? try [loadedValue: first load/all Rawvalue] [LoadedValue: RawValue] ;; apply rules ;; === foreach [rule message] Rules [ if not (do replace/all copy rule 'item LoadedValue) [ print [LoadedValue fails rule: Message] break ] ; if ] ; for I'm using a valid date here so it gets through more of the checks eventually failing because specialcheck is not defined. I hope this has helped you out. If you have any more questions about it, please ask... we all cringe here at REBOL HQ when we see the unnecessary use of DO with strings... you're always DOing REBOL code so why not start that way? Sterling Hi all, It may just be my irredeemably old-fashioned mindset, but everywhere I turn in Rebol I see the need to 'DO strings.

[REBOL] Re: read bug?
It seems that this thread has wandered from POST to GET problems.
I'll address the issue with GET as best I can.
People see that a long URL used with read:
read http://foo.com/cgi-bin/cgi.r?name=value-of-really-long-data
gets truncated or otherwise fails to read. I ran some tests on my
machine here (Linux w/ Apache) using Core 2.5 on both the client and
CGI end. I made a really big URL of over 7K which looks like the
example above. It made it through just fine.
However, I have seen a truncation of sorts happen in some situations
here though most have been using a browser going to a REBOL CGI
script. Have you tried the same read using a browser?
One possibility is that the receiving system truncates the GET data.
Remember that when using a GET method, all CGI data is passed to the
program on the server using environment variables. If any of the
client browser, webserver, or system env. vars limits the length then
the CGI script on the other end will not get all the data.
So take REBOL out of the picture and see what happens:
#!/usr/bin/perl
print Content-type: text/html\n\n;
while (($key, $val) = each %ENV) {
print $key = $valBR\n;
}
There's a little perl (yuck) cgi that'll print the env. vars for you.
Try your request with REBOL or a browser against that and see what you
get. Also, with REBOL, turn 'trace/net on' and do the read. What you
see printed to the console is EXACTLY what is being sent into the TCP
port to the server.
Let me know what you find out.

[REBOL] Re: integers and sizes
It all looks right. The to- conversions are just that and do not transform a value into another value. They are conversions which means that they return a new value of the new type as long as the original type can be converted into the target type. To work with your examples: a: 21 b: 105 / 5 type? a ;integer! type? b ;decimal! to-integer b ; 21 type? b ;decimal!, wow, that is interesting to-decimal a ;21 but: c: to-integer b ; 21 type? c ; integer! c: to-decimal a ;21 type? c ; decimal! The same thing works with series values that have extra storage associated with them: a: "foo" type? a ; string! b: to-issue a type? a ; string! -- still type? b ; issue! -- converted insert a "bar-" a == "bar-foo" b == #foo when b was converted from the string "foo" to the issue #foo it was copied and therefore is a new value. If the old value is changed, the new value is unaffected. Sterling From: "Travis Watkins" I fear that this may be a bug: Integer? 105 false (this is correct because you only use 4 bytes to represent an integer) integer? 21 true integer? (105 / 5) false (note, this is 21, the value which was true before) apparently any number which was at one point associated with a value greater than an integer is not an integer, even when reduced to a sufficently small number. Note: Win98 system Well, this does get interesting. To continue with your example: a: 21 b: 105 / 5 type? a ;integer! type? b ;decimal! a = b;true, as it should be same? a b ;true, as I guess it is strict-equal? a b ;false, ahhh, I feel better to-integer b ; 21 type? b ;decimal!, wow, that is interesting to-decimal a ;21 type? c ;integer! It is interesting that sometimes REBOL "leaves" it as it was (a decimal or an integer), despite trying to coerce it. I can't tell if this is a bug or a feature, but I could imagine circumstances where it might trip up programming logic.

Your problem is that you are calling INFORM from within another INFORM. This is not such a safe thing to do. If you just change "inform out" to "view/new out" it works fine except that the second pane is not modal. You might also get around the problem by doing a hide-popup before doing "interrogation" and then re-popping the "out" layout when the interrogation popup exits.

[REBOL] Re: Complex Series Parsing (Part 2)
Well, before anybody goes further into the "here's something that
works for the last input you posted" followed by "but then there's
this input that doesn't work" path, lets go back to the definition of
input and output.
If you use load.markup and trat the REBOL words you have in your block
as strings like Andrew suggests (which is a better way to deal with
them), then you have these input elements:
* text -- open text tag
* "???" -- some arbitrary string
* ??? -- some other open tag
* /??? -- some close tag
* /text -- a close text tag
Your input looks like this:
probe input: load/markup {tag0/tag0 text this and that
tag1those /tag1and these/texttag2/tag2textThere and
then/text}
== [tag0 /tag0 " " text " this and that^/" tag1 "those "
/tag1 "and these" /text tag2 /tag2 text "There and^/then"
/text]
You can get rid of the whitespace-only strings if you want to that are
created due to whitespace between the tags.
Now write the spec:
* any combination of input elements up to text
* open text
* any combination of "???", ???, /??? where text whould be
inserted if front of each "???"
* /text
* start the whole process over
Done.
That's all you've told us so far. Each item above is essentially a
parse rule already. Some can be joined together:
* [thru text]
* [any [
/text [thru text]
| tag!
| string! mark: (insert back mark text) string!
]
]
Now we just assemble:
; skip the immediate string after text so we don't add a second one
start-rule: [thru text [string! | none]]
parse imput [
start-rule
any [
/text start-rule ; start over
| tag! ; eat any random tags
| string! mark: (insert back mark text) string!
]
]
probe input
And presto!
Sterling
This is on the right track. But more complexity would arise... here is an
advanced XML structure...
y: [tag0/tag0 text this and that tag1those /tag1and
these/texttag2/tag2textThere and then/text]
output would be...
out: [
tag0
/tag0
text this and that
tag1
text those
/tag1
text and these
/text
tag2
/tag2
text There and then
/text
]
There is method to the madness, I've got the "madness" part down pat, now if

I'm not sure I understand what you are really trying to do. Usually
with parse, once you describe the format of what you want to parse and
the output wou desire, the parse rules just fall out onto the screen.
Correct me if I'm wrong:
Input is a block with the following format:
A text tag followed by a series of words with any number of non
text or /text tags interspersed and ends with a /text tag.
The desired output is the same block except that every place there is
a non text tag in the block a text tag should be placed after it
and before the next series of words. The ending /text tag should be
removed.
For this you don't need parse at all. Just march through the block
and insert the new text tag as needed:
y: [
text This is some text tag with a tag added /tag and then some text
/text
]
forall y [
all [tag? y/1 y/1 text y/1 /text insert next y text]
all [y/1 = /text remove y y: back y]
]
probe y: head y
Perhaps your rules are a bit more complicated in which caase you need
to define them and then see what's the best way to do it. Parse may
be necessary but this simple case can be done quickly another way.

Hello all.
How do you parse this...
y: [
text This is some text tag with a tag added /tag and then some text /text
]
So that you get this
n: [
text This is some text
tag
text with a tag added
/tag
text and then some text
]
I tried this...
n: []
z: parse y none
foreach val z [
either find val "" [append n val] [append n rejoin [{text } val]]
]
But then I get
n: [
text
text This
text is
text some
text text
tag
text with
text a
text tag
text added
/tag
text and
text then
text some
text text
/text
]
So how do I "collect" all the text until the next "tag"?

[REBOL] Re: sending 'none to CGI
It will arrive as a string and remain that way until you change it.
REBOL, when run in CGI mode, gathers up the relevant environment
variables and drops them into the system/options/cgi object. The
query-string holds the exact text following the '?' in the URL. You
can then make use of 'decode-cgi to make checking values easier:
system/options/cgi/query-string: "value=none" cgi-obj: make object!
decode-cgi system/options/cgi/query-string
The cgi-obj will now be an object containing the word 'value which has
the value of the string "none". REBOL purposely does not evaluate any
of the CGI information as that would open a security hole.
In order to change that "none" into a REBOL none value, you would need
to use load.
load "none" will result in a REBOL none value.
However, if your query string looked like this:
value=none%20none
then the resulting decoded string would be:
"none none"
and loading it would result in a block:
[none none]
which, as you point out below is a block with unevaluated words which
means that neither item in the block is actually the REBOL none
value. They are both simply the word 'none.
It is best, when writing REBOL CGI applications, to know ahead of time
what kind of data you are expecting to receive. You can then use
'make object decode-cgi' to help you make an object with the values.
Then, for non-string values, either wrap a direct conversion in a try
block:
if error? try [to-integer cgi-obj/usernumber] ["return error page"]
or check the type of a load (which is safe because it does not
evaluate any code):
if not integer? load cgi-obj/usernumber ["return error page"]
Well, that was rather long-winded for a one line answer. Sorry.
Sterling
If I send the following text/html output to the user
{A HREF="http://www.domain.dom/cgi-bin/script.cgi?value=} none {}
and he or she clicks on the resultant link, what value will be passed to
CGI? Will it be a 'none value REBOL can understand?
I suspect that it will be a unevaluated word, like 'none in a block:
[none]

[REBOL] Re: reb sites - Zork! thoughts
That's a cool idea. You would need to build the language parser and basic game engine. With 'parse, the language interpreter could be built pretty fast and easily extended. I think the hard part of making it so distributed would be keeping the game continuity. Two different people may design adjacent rooms, one being a very futuristic space capsule while the other is some bizarre, surreal room with chairs on the walls and 3 legged people drinking soda through their fingertips. Nevertheless, REBOL would be a great platform for it. Sterling I haven't downloaded a copy of /View since the first release, mainly due to the lack of current documentation. One of the fun things I discovered was the Reb Sites links. One thought comes to mind: creating a massively distributed, Internet-based role-playing game the likes of Zork! where the world is created by anyone and everyone. Persons help to create their little pieces of the world by uploading a valid XML file to a central server. The XML file defines a specific "room" or "tile" and also the creatures, objects, actions, and dialog within each room. You could even create a room Editor using the Reb interface.

[REBOL] Re: Rebol and FTP (recursive stuff in particular)
Yes. FTP will close the old connection to a given host if a new one is made but in a different directory. That is also the same behavior I see here with the latest experimental (2.4.39 on Linux). I also watched my netstat and only one connection stayed active. The only situation where you could end up with more than one connection to a single host is if you are using two different users to log in as. If you really want to make sure that all connections are closed immediately then you can set the port cache size down to zero: system/schemes/ftp/cache-size: 0 This will have the effect that the control connection is closed at the end of the request and no ports at all will ever be cached by REBOL FTP (not so efficient). If you set it to 1 then it should cache only one connection. If you are only connecting to a single host as a single user then you should see no difference in how it's all working. All sequential reads within a single directory will reuse the command port but access of a different directory will create a new command port and close the last one. If you are seeing different results... like multiple command ports open to the same host, please send as much info as you can into feedback as a bug report so we can track down the problem.

[REBOL] Re: clean-path
The main reason that URLs are not translated by clean-path is basically that you do not really know what directory transaltion is in effect on the contacted site. Take FTP as an example: read ftp://user1:[EMAIL PROTECTED]/readme.txt This file will most likely reside in /home/user1/readme.txt. Now lets say that user1 has shared their directory and this file for others to read. So user2 wants to get it: read ftp://user2:[EMAIL PROTECTED]/../user1/readme.txt This will work because the "root" directory that is specified by ftp://user2:[EMAIL PROTECTED]/ is actually in /home/user2/. The problem with cleaning the URL is this: clean-path ftp://user2:[EMAIL PROTECTED]/../user1/readme.txt would come out as: ftp://user2:[EMAIL PROTECTED]/user1/readme.txt which is clearly not right. Some FTP servers will not allow you to back out of your home directory but some do. The point is that we don't know so we leave it open and do no translation.

Right. I see what you mean. Perhaps the more frequent use of clean-path on a URL is this. We'll talk about it the next time we meet about /Core fixes/enhancements/etc. The only issue may be that we would be breaking code that relied on the current behavior... how much of that there is I can't say. The slider does not update on the text list unless you tell it to. I use the following function in my code to update text-list sliders every time I mod the list.

[REBOL] pop question Re:(3)
No problem. If I understand you last question correctly, it means something like this: How doe the server insure that the client only deals with the currently delivered emails while it has the box open? If that's the question, the answer is that I don't know all the specifics. However, from messing around with the POP protocol and watching my mailbox at the same time, I've noticed that the server does not deliver new messages to you mailbox (a simple file) until the mailbox is closed. It keeps the incoming mail in it's spool, a temp file, or some such place until it is safe to deliver. It also, as I recall, removes the mailbox file while you have it open. so when you open the mailbox and then go look for the file on the server, it actually appears empty on the server though you are reading a bunch of messages on the client side. I figure this is to protect the system from mailbox edits while the box is open... could royally mess things up. If I'm incorrect anywhere here or somebody knows all the nifty details, feel free to correct and/or add. Sterling Thanks Sterling, I will perform the suggested testing -- I wouldn't want to turn something loose that mucks around in someone's mailbox until I was sure it was bulletproof AND that I understood exactly how it worked.

Sterling Hi, just wondering how you deal with checkboxes when doing CGI. if you do something like: cgi-data: make object! decode-cgi system/options/cgi/query-string you lose multiple values with the same name, like you'd have in the case of multiple selected checkboxes.

I did a search in all the code on the book's CD and found something that can aid you in generating the HTML for form elements, but nothing that lets you read them.

[REBOL] FTP error Re:(2)
Are you perhaps behind a firewall? It looks like REBOL's FTP protocol
is having trouble establishing the active connection for the data.
Try setting:
system/schemes/ftp/passive: true
and try it again.
Sterling
With a trace/net on, one can see that Rebol parses internally the URL,
and I'm wondering if this is not the source of the problem :
URL Parse: myname password ftp.xoom.com none backup/ FRANCO22 final.DWP
Net-log: [
["PORT" port/locals/active-check] "200"]
Net-log: "200 PORT command successful."

Net-log: [

So, is this a bug?
[REBOL] Challenging script idea Re:

for each file if the number of appearances is different.
Well, enjoy!

I was noticing in the script library (web section)
that mailpage.r and websend.r are identical. So
here's the challenge: as powerful as parse (and other
language processing features) is, can someone come up
with a script that would analyze the tokens in a pair
of scripts and determine when they are essentially the same?

[REBOL] Linked list in rebol Re:
Well, as you know, you get doubly linked lists for free in REBOL.
That's called a block. To do the other part, I'd just make the items
in your block another block or an object. Then hold an index in one
of the vars in that.
triple: copy [] ; the linked list
foreach item [[none 42] [4 9700] [1 15] [3 1846]] [
repend triple item
]
now there are four items in triple. Each item is a block where the
first number is what you call *mrk in your structure and the second
number is the num you have in your struct. The marker is an index
back into triple so that you can do 'pick triple triple/2/1' and that
will bring back the block indexed by the third link of the second item
in triple, namely item number four "[3 1846]".
Another thing you could do is put an actual reference to triple into
the block:
repend triple [skip triple 3 675]
This way the first item in the block is actually a refernce into the
triple block.
You could do this with objects as well instead of blocks but I'll
leave that excercise to the reader. The implementation you choose
should be the one best suited for your application. Take into account
all the uses of that third link, how much data you want to store in
this item, and how you will be manipulating it.
Sterling
Hello:
I'd like to implement a *triple* linked list in rebol.
Below is a "c" structure: I'd welcome advice on how
to translate this to a rebol data structure.
If I'm correct, the nxt and prv elements are encapsulated
by a rebol list. What I'd like to figure out is how to
manually reference another node in the list.
(the mrk element)
typedef struct test_node
{
struct test_node *nxt; // points to next node
struct test_node *prv; // points to previous node
struct test_node *mrk; // points to a randomly selected node
long num;
}TestNode;
Thanks In Advance

[REBOL] Bcc?? Re:
An important note is that when yo uuse SEND, the [block of addresses]
is, by default, entirely Bcc. If you want it to show up in the
destination email with the list of people you sent it to, you'll want
to use send/header and make a header object like below. Then you'll
want to set the to field to the comma separated list of addresses:
send-to: [[EMAIL PROTECTED] [EMAIL PROTECTED]]
cc-to: [[EMAIL PROTECTED] [EMAIL PROTECTED]]
bcc-to: [[EMAIL PROTECTED] [EMAIL PROTECTED]]
header: make system/standard/email [
from: [EMAIL PROTECTED]
to: replace/all form send-to " " ", "
cc: replace/all form cc-to " " ", "
subject: "Message subject"
]
with any other headers you like.
Then:
send/header join join send-to cc-to bcc-to "message text" header
and it should be off. And the other end sees that you sent the email
to two people, and cc'd two others while you actually sent it to 6.
If you want to add the Bcc header to the ones you Bcc'd, then just
mail those after and add the Bcc header field for them.
Bottom line is that REBOL is not trying to pretend to be an emailer.
You get to decide how you want your mail to look. If you want an
extra reference, check out the %attach.r script on REBOL.org under the
'email area of the script library. I wrote that to send mail with
MIME attachements (looks like you're doing the same given that content
type header) and it does what I've explained above.
Sterling
HI,
does anyone know how to
create a custom email header
that includes Bcc.
This is what I tried:
tommy: reform [[EMAIL PROTECTED] [EMAIL PROTECTED]
[EMAIL PROTECTED]]

From: "[EMAIL PROTECTED]"
Bcc: tommy
MIME-Version: "1.0"
Subject: "Thank-you :)"

[REBOL] downloading big file via http Re:(2)
url: http://www.someserver/somefile.rm
http: open/direct/binary url
print "http opened."
while [true] [
w: wait [http]
{more code here}
]
it fails on the w: wait[http] line. why?
wait works on a tcp port, I know that from another project.
Does wait not work with an http port?
That might be a bug... it's being looked into.
I ran the url through my IE browser and it never timed out,
but you could watch, after about around a megabyte of data,
the download rate would plummet as if the server basically
lost interest in the request.
Then, I found that after cancelling, when I requested the same
url, IE was smart enough to just resume where it left off.
Well, it took about 20 re-tries, but I eventually got the 14.3 MB file.
IE resumed the download because it hadn't wiped the file from it's
cache just yet... you're lucky with a file that big.
Now, don't tell me you are going to let IE lick you!
NEVER Divide and conquer! Remember the Alamo! I've not yet
begun to fight!
How can I do the same thing (dowload the whole file) in Rebol?
You need to invoke a magic incantation and sacrifice your Perl
installation to your newfound REBOL gods.
is there a way to specify restarting a download in Rebol http?
Funny you should ask. I've just been discussing this exact thing with
Julian Kinraid. He's already modified both the FTP and HTTP protocols
to allow restarts of downloads. We'll be covering these possible
additions in our next devel meeting but that stuff wouldn't be out
'til next release and I'd hate to make you all wait like that.
So what I'm going to do is post some unsupported protcols onto
REBOL.org that have these modifications. It'll take a little time so
don't _expect_ them to be there by the time you see this mail though
they might be. I'll make the page at:
http://www.rebol.org/unsupported/
So you can check back there for them. I'll post a message when it's
all there.
is there a way to set it so it won't timeout?
Note: the timeout is actually on the client side,
because IE never times out...?
I don't think so right now.
The file I am trying to download is
http://www.grafxsource.com/RnaG/6-3-00-Caitlin-45.rm
It's basically a capture of a couple of hours of Irish radio.
-galt
You also asked in another message about the size of the file. IF the
server reports it (and you trust that), then once you do open/direct
on the http file, you can use port/size to see the size:
http: open/direct/binary http://www.grafxsource.com/RnaG/6-3-00-Caitlin-45.rm
http/size
== 15182055
Yup. It's big.
Well, you'll excuse me now. I just promised to do something and I
guess I'll do it now.
Sterling
[REBOL] restart in FTP and HTTP
OK. Two scripts have been posted to REBOL.org though not yet linked from the main page. Go to: http://www.rebol.org/unsupported/ for a brief text blurb and the files. These are the FTP and HTTP protocols modified so that a wisely formed read/custom call will make use of the partial read functionality of many web browsers and the restart command that exists in some ftp servers. If these changes make it into a full release version of REBOL then thes files will be removed from this location never to be seen from again as they perish into /dev/null. Sterling If I totally messed up and the files fail all over the place for you I'll fix them quickly so they work but they are unsupported so nobody is going to constantly be updating them with bug fixes as you find servers they don't work on. If somebody wants to take it on as their script, then just grab it and post it back into the REBOL.org script library. Then you can update it all you like. Party on Wayne! Party on Garth!
[REBOL] detach.r Re:
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...
cut out the rest
[REBOL] detach.r Re:(3)
Hmmm... well, it got all the attachment parts but blew out right at
the end.
Try changing:
if find/match body "--" [print "breaking... attachents finished" break] ;
we're at the end of the message attachments
to:
if any [find/match body "--" not fimd headers/content "^/--"] [print
"breaking... attachents finished" break] ; we're at the end of the message attachments
That way, it should gracefully exit if it either finds the proper end
marker or if it can't find another attachment.
Sterling
Doing as you said overcame the problem of the function looking for a string!
instead of an object!
But...
detach msg
starting decoding process...
== none
Then I had to change
if boundary: find/tail boundary {boundary="}
to
if boundary: find/tail boundary {boundary=}
Then...
do %detach.r

[REBOL] Getting an URL from a form Re:(6)
I did some work on this myself. It's a bit annoying when sites don't have a mechanism for a GET HTTP request. A while back Martin Johannesson wrote a simple http-post script to do those requests. Then, to help automate it a bit, I wrote a form parser that reads a web page, parses out a form and returns an object with that info in it so you can see what it requires to post it back. In the case you are talking about, here's what I can do: probe parse-form http://www.hembiocenter.se/menu.asp make object! [ method: 'post action: "search.asp" inputs: [word: none search: "actor" search: "title"] hidden: [] ] Then just change some fields so that your values are filled into the inputs block for the words you want... inputs == [word: "sleepy+hollow" search: "actor" search: "title] since 'search' appears twice, it's the radio buttons and the last one will be used. Then... page: http-post-form http://www.hembiocenter.se/search.asp inputs and presto! You have your page. On pages with hidden inputs, you will have to do an 'append inputs hidden' to pass the rest of the form data on. Both scripts are available form rebol.org... http://www.rebol.org/web/http-post.r http://www.rebol.org/web/parse-form.r Anyway, it'll help when you want to use a form where there is no alternate GET method to use.

[REBOL] FTP crashes rebol Re:(3)
FTP can do quite a number of things... we don't implement them all because the "standard" or "required" set of commands is rather small and support for the extra features is not guaranteed. Within REBOL right now, you can: read, write, append to, delete, and rename files read, make, delete, and rename dirs I think that's the list. However, the FTP protocol itself has many other commands that are optionally supported by servers. There is a command to restart a broken transfer at a specified point, and a few that can specify the structure of the target file system or file to be used... I'm not really dure how they get used or how many servers implement stuff like that. Append is probably the only thing there you didn't know about. FTP cannot do any mid-file editing within the protocol... for that you'd have to transfer the whole file back and forth and do the edit locally. It might be neat to implement some way to get that download restart command worked in but how do you put that info into the URL? Sterling Sterling, in your note to Tim to say that append should work, although it would be slow and inefficient. Is this really true? I didn't think you could modify parts of files using FTP. What can FTP really do? -galt

[REBOL] Limit on data in CGI Post? Re:(2)
CGI POST calls will send the data you want to the CGI process. When yo uare handling it yo umay need multiple reads to get it all... it may not all be there when you do your first read. You'll notice that with POST you also get some headers and one of them should tell you how much data to expect. Therefore you can write a read loop to get it all. You would most likely need to check to make sure that the port is still open as well as read from it (copy) to deal with data transfer delays and all. Also, decode-cgi is only for the GET request and not for POST. Yo uwill find that POST data has a more complex structure... almost like an email with attachments. You will have to deal with that data yourself.

[REBOL] Problem with SMTP Re:
If you have a proxy set, REBOL will go through it by default. You can make a list of bypass machines like this: system/schemes/default/proxy/bypass: ["center.uniba.sk"] That should bypass the proxy when it connects to your mail server. Sterling Hi, I have problem with network settings in REBOL (tested with Win98 and Linux RH6.2). When I set correct SMTP server and proxy server (3 CERN) I can't send email. But when I set only SMTP server without proxy it's ok. In ethereal (network sniffer) I can see correct communication when I haven't proxy. But when I have PROXY in ethereal is communication with PROXY(why?) but nothing with SMTP server. There are only 5 packets. Two standard UDP with DNS query for PROXY host name, and then 3 packets with PROXY. Here are my user.r set-net [ [EMAIL PROTECTED] center.fmph.uniba.sk none proxy.sturak.sk 8080 generic ] Please tell me what's wrong. Thanks Peter Hanusiak
[REBOL] [REBOL]string to series function Re:(3)
Fair enough. I have little time to give a complete course on parse so I went for the shortest version. I expected to see a few other responses to this thread as well and sure enough the old-time REBOL-masters of the outside world give a more full answer than us insiders have time for. Take it easy guys, Sterling Hi Sterling, one little detail: your approach works well enough with this particular example because space is one of the desired delimiters. Conceivably Tim may want a more universal solution that enables him to determine whether or not he wants to include spaces in his parse rule. In that case IMHO it would be more appropriate to use parse's all refinement and - for the sake of this particular example - include space explicitly as a delimiter in the rule: With space: parse/all "one#two%three four" "%# " == ["one" "two" "three" "four"] Without space parse/all "one#two%three four" "%#" == ["one" "two" "three four"] Note that the second version returns "three four" as one string because space is not included in the rule.
[REBOL] new proxy server and related problems ... Re:(3)
The new proxy server is probably a Squid proxy server, which means that the proxy-type needs to be set to 'generic, not 'socks or 'socks5. I assume that your netscape settings have the host and port number listed under the http proxy area, not under socks. Anyway, try it as generic and see if that fixes the problem. Sterling [EMAIL PROTECTED] wrote: Hi Petr, have you tried to set the http proxy settings? I.e. system/schemes/http/proxy/host: proxy.sec.trz.cz system/schemes/http/proxy/port-id: 3128 system/schemes/http/proxy/type: 'socks. system/schemes/http/proxy/user: none system/schemes/http/proxy/pass: none the strange thing is - netscape works.

I even tried set system/schemes/http/port-id to 3128, or directly site: read http://www.rebol.com:3128, but it still doesn't help. Will www.rebol.com be used for system/schemes/http/host?

[REBOL] ftp limits? Re:(3)
Hi Nigel,
I tried this and did get a timeout but I also got a timeout under
Netscape reading the same site and received no directory listeing
there either. That, unfortunately, tells me nothing other than the
server is really slow. You mention that you always get "some error or
timeout", so what error other than a timeout have you received? That
may be of some use.
Sterling
Thanks for that. The directory that causes the problem is set drwxr-xr-x and
all the files are -r--r--r--. So I don't think this is the same problem.
This certainly looks like a bug in Rebol to me. The directory downloaded
through an ftp client results in a 137k download (about 1500 files). I
suspect the problem is caused by the number of files.
I really do need an answer on this - if Rebol cannot do what I want I need
save my efforts and look elsewhere.
If anyone want to give it a try...
system/schemes/default/timeout: 1000
print read
ftp://anonymous:[EMAIL PROTECTED]/aix/fixes/cad/other/catia_o
em_v4/IRIX/
Replace email_address with you correct email address (all activity is
logged)
Depending on proxy/no proxy/Rebol platform you always get some error or
timeout without the directory listing ever being received.
Thanks
Nigel

[REBOL] ftp limits? Re:(4)
Somebody will take a look at it. I did manage to get the same server response error which I think is generated if the server times out before REBOL does and closes the connection. REBOL expects to hear something back and does not so it fails to parse the empty response. Thanks for the info Larry, Nigel. Sterling Hi Nigel, Sterling There does appear to be some kind of problem with the REBOL ftp is this instance. I was able to get the dir listing with WS-FTP although the server was slow (took about 150 seconds). With REBOL I got (don't need the user e-mail if set-net has e-mail configured): system/schemes/default/timeout: 5000 == 5000 list-dir ftp://ftp.europe.ibm.com/aix/fixes/cad/other/catia_oem_v4/IRIX/ connecting to: ftp.europe.ibm.com ** User Error: Server error: tcp 421 Timeout (1800 seconds): closing control connection.. ** Where: list-dir ftp://ftp.europe.ibm.com/aix/fixes/cad/other/catia_oem_v4/IRIX/ I had no problem getting the dir lists for each of the parent directories using REBOL, so I am inclined to agree with your speculation that the number of files or the time required for the server to send them is part of the problem. Based on the tests with WS-FTP, the server should have sent back the dir-list in about 180 seconds, REBOL apparently was unable to receive or acknowledge this, leading to the server timeout at 1800 seconds. The results of using 'trace/net are shown below. I have CC'd this to feedback, perhaps Sterling or someone else at Rebol tech can diagnose the problem? (I see Sterling has already replied:-) I just tried WS-FTP a seond time. It took 120 seconds for the dir-list to start downloading. The dir-list was fine. Hope this helps Larry
[REBOL] Unknown script error Re:
I haven't been keeping up with the beginning of this thread at all so I don't know what you are doing exactly (and don't have much time to deal with it too much myself either). However, I'm guessing that these are ftp transfers you are dealing with, right? That line you are wondering about is part of the protocols system of talking to the server. The error occurred because REBOL was expecting a response from a command sent to the FTP server and did not get an answer. Maybe the server closed the connection. Do you have a long timeout set for the transaction? If so, the server may timeout before REBOL does and close the connection on you causing REBOL to throw that error. Sterling I am trying to author a script to download via ftp. Yesterday I hurdled the problem of getting files bigger than 16 MB by using a function suggested by John to "chunk" the files into smaller pieces thus avoiding memory problems. Today, I have another problem. It appears that I cannot transfer too many bytes in one batch. I can transfer hundreds of small files at a time, no problem. I can transfer a single file 100MB, a little slow, but no problem. The problem lies when I transfer 5 files totaling 200+ MB. I get a script error, either after or during (I am not sure on what line it dies) the transfer of the last file. The error reads: ** Script Error: find expected series argument of type: series port bitset. ** Where: if not find/match/any server-said response Funny thing is 1) It looks like the files transferred fine when I look at the resulting directory, and 2) the line "if not find/match/any server-said response" does not exist anywhere in my script or any other rebol script on my system. Any clues would again be appreciated. Brian

To me - it looks like REBOL simply parses out the username:password from
the URL. But I'm not sure what the results of the trace mean. I can see
that the Authorization chalenge comes up - the little box that pops up in
your browser when accessing a password protected resource is referred to
as "Basic Authentication" - not just in Microsoft's parlance.
So - I'd say the server is responding appropriately - but that REBOL isn't
reacting to it correctly, and not handing it the username and password...

[REBOL] Personal Web Server Re:(3)
Well, that set of instructions has worked for others before. The HTTP header problem may be there if your script does not print out a line like "content-type: text/html" at the top with a blank line after it.

[REBOL] FTP Problem - Multiple Connections Re:
REBOL attempts to maintain one connection per site contacted. If more
connections are being made, you should see a message like "connecting

finished flawlessly with only one connection made.
So when you run it, does it print out multiple "connecting to ..."
messages?
Sterling
I have a problem that I hope can be solved. I operate several websites
and would like to make a script to upload the site data whenever there is
a change. My goal is to use Rebol.
I wrote the script below to move an entire site at once. I tested
uploading to one of my internal servers (at home) and it worked like a
champ. So, I then went to upload my data to my real website and I
received an error stating that only one {1} FTP connection was allowed at
any given time.
Because of that, I went back to my internal servers and monitored the FTP
connections, and sure enough, 5 Connections were generated by the script
below (it moves about 30 files in total - a very small, test website).
These connections persisted until I shutdown Rebol.
My question is, how do I open an FTP connection, write to that connection
as many times as I like, and then close that connection, all while
maintaining only one {1} connection to the FTP Server?
Thank-you,

[REBOL] clean-path when arg is url? Re:(2)
Well, the reason that clean-path does not clean up URLs is that you may want that information. Take, as an example, FTP. For a file on your hard drive, the path: %/../../foo/bar/baz is the same as: %/foo/bar/baz zso clean-path can clean that up without loss of information. However, the URL: ftp://my.domain.com/../../foo/bar/baz may not be the same file as: ftp://my.domain.com/foo/bar/baz because my home directory may be in /home/me so I am really accessing a totally different file in the two cases. It is dangerous to play around with paths when you could be sitting in a virtual root directory but still with the ability to go back to the real root. Sterling Hi Joel, Not sure why clean path is limited to non urls. Why not put in a request for it to be modified, to [EMAIL PROTECTED] ? In the mean time there is function to clean http paths on the Rebol Examples page http://www.rebol.com/examples.html Clean HTTP-Path "To remove /../ from within HTTP URLs.

[REBOL] Fixed format/width field files in REBOL Re:(2)
Instead of doing the read/lines into a block and parsing each line, could you not just have the line ending be part of the parse rule? assume data is your whole body of text before you created the block called 'tracelines' Then, instead of the last line in rule (to end), change that to 'thru newline' and do: parse/all data [ some [rule (print rejoin [time s ts s tt s adr s aack s artry s dbg s ta s dh s dl])] ] the parse rule now reads your data from one line and ends by reading thru the newline. Then the print happens and it repeats until all lines have been parsed. This way you don't have to break up the string into a block and write a whole loop to iterate over it when parse can do all the iteration for you. Sterling Andrew, I used the following snippet to translate logic analyzer trace files (which have fixed width fields, many of which I want to skip) into something that our simulators like. The file was read using read/lines into a block (tracelines) which was then parsed by the following: rule: [ 16 skip copy adr 8 skip 4 skip copy ts 2 skip 6 skip copy tt 4 skip 4 skip copy tbst 4 skip 20 skip copy aack 4 skip 4 skip copy artry 5 skip 11 skip copy dti 6 skip 6 skip copy dbg 3 skip 5 skip copy ta 2 skip 6 skip copy dh 8 skip 4 skip copy dl 8 skip 24 skip copy time 10 skip to end] s: " " trc: func [] [ foreach l tracelines [ parse/all l rule print rejoin [time s ts s tt s adr s aack s artry s dbg s ta s dh s dl] ] ] Ron
[REBOL] Is today the day? Re:(5)
The final ODBC user view has not been fully determined yet so I can't say quite how it will look. Sterling ODBC Implementation Question... Also what are the other main selling points beyond ODBC database access at this stage...? Command won't talk directly to mySQL, but you'll be able to access it through ODBC. Native d-base implementations are slated for early Q1 (also including Oracle, Sybase, etc.). Quick question - are you attempting to stick with the somewhat standard ODBC API used in everything from PHP to VC++ to LotusScript? By this I mean the somewhat usual combo of: snip And then, you could browse thru the result, pulling contents of fields, etc. - Porter
[REBOL] database testing
We're currently testing some different databases on Linux and other *NIX systems and I'm looking for a link to a mySQL test database to work with as well as links to the required shared library (.so) ODBC drivers for other databases and test DB's there as well. So if you work with certain databases and know where good resources are please mail me offline at [EMAIL PROTECTED] We can't test them all but if we can save the time to gather all the software we can test more of them. Any assistance is greatly appreciated and it'll help you in the long run. :) Sterling
