[REBOL] can rebol strip this type of text file?
hi all i am new to scripting (rebol and python) and was wondering if it was capable of doing to the following and if so..how? the following is an example of what i need to strip and turn into a tab delimited file.. the entries are from a music database that is updated weekly..it is in lotus notes so i export from there and it dumps this file out with the new titles for the coming week (here the 19th June) i only need to get the rows with the double astericks at the start (i put those in for this post, they are not there in the normal file) and then strip the words at the start and then put a tab in between them so i can bring it into excel for the sales team to look at i would need a first row to describe each column also maybe something like Title tab Artist tab Cat no tab APN etc etc the tracklisting is a little more complicated as it has multiple tracks within the row..they are seperated by commas i think that it won't be that hard but i had no success in perl so i thought i might try rebol or python... thanks in advance keith FORM: Popular Recording CMTYPESWITCH: Popular RELOCORIGINAL: 55864A2603AC94ACCA2568F200224388 CMCOUNTRY_ORIGIN: CMGENRE_CODE: **CPTITLE: INFINITE POSSIBILITIES **CPARTIST: AMEL LARRIEUX CPOARTISTS: **CMCATNUMBER: 4948792 **CMAPN: 9399700067507 **CMARIAPRICECODE: C9921 **CMARIAMEDIACODE: 21 **CMARIADISTRIBUTORCODE: SMA CMARIAPACKAGECODE: **DMRELEASE: 19/06/2000 cMDateFormat: 19/06/2000 12:00:00 AM DMDELETE: cMDeleteStatus: No **CMLISTPTRACKS: GET UP,I N I,SWEET MISERY,SEARCHIN' FOR MY SOUL,EVEN IF,INFINITE POSSIBILITES,SHINE,DOWN,WEATHER,MAKE ME WHOLE,GET UP (THREAD HAD FUN MAIN MI,GET UP (MV MIG MIX (RADIO)) CMLISTPARTISTS: ,,, RELOCMEDIA: F73C80183A01A8D7CA2568F2002A5517 **CURMPRICE: 15.91 **CMTYPE: Compact Disc CMRECORDCOMPANY: SONY MUSIC CMPACKAGE: CMARIADISTRIBUTORHOUSECODE: cDistributorHouse: CMLOCALE: Y $UpdatedBy: CN=PPT/OU=AEROS/O=JUKEBOX $Revisions: 02/06/2000 05:42:22 PM,02/06/2000 05:42:22 PM
[REBOL] restart in FTP and HTTP Re:
[EMAIL PROTECTED] wrote: 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! Also, remember that the first byte is 0... read/custom http://www.ibm.com/index.html [restart 1 reend 2] This reads the *second* byte and the third byte, so the length is (3 - 2) + 1 = 2 read/custom http://www.ibm.com/index.html [restart 10 reend 20] Read from the eleventh byte upto and including the twenty-first byte, a length of (21 - 11) + 1 = 21 Rebol will also translate line terminators, which is why (on a Windows machine) - length? read/custom http://www.ibm.com/index.html [restart 100 reend 1000] == 899 The length that was actually read is (1001 - 101) + 1 = 901, but Rebol removed two #"^M"'s. Using the binary refinement is a wise choice - length? read/binary/custom http://www.ibm.com/index.html [restart 100 reend 1000] == 901 The same applies to ftp, [restart 1] will start reading from the second byte, and you'll probably want to use the binary refinement to avoid confusion.

Ok peoples, I've spent all day looking at %detach.r, Ryans email, rfcs and the inner parts of Rebol. And I blame Ryan for it. :) I really couldn't let the code in detach go to waste. I chopped %detach.r to pieces and put it back together again (no guarantee all functionality is the same - in fact I know it is different). I called my version %import-attachments.r. Because I wanted to import them as a block and leaving hanging of an email object as a new field. But alas I think I was misguided. Nevertheless! export-attachments found in this same file seems to work :) Even for Ryans email from the Be mailer. I have assumed, that multipart message can be nested (as is the case with the Be mailer). This is explicitly allowed according to the rfc. Please check it out and let me know how many mistakes a newbie Rebol programmer has made. :) Please note that I have only got it working for content-type of image so far. Next to do would be text and application. I'm very happy if someone else wants to "spit and polish it". Brett.
[REBOL] By any other name (CGI, HTTP)
- Open Your Mind - I didn't find a way in the RFC, but maybe I did a poor search. I don't have the time to study Apache right now, so I don't know if the answer is there. The question: is there a way for an Apache-handled CGI script named john-doe.r, and referenced to as such in a web form, to output a web page named john-doe.html (or even john-smith.html)? In other words, I'd like to have form action="john-doe.r" method="get" in the form, click on the submit button and see john-doe.html on my browser. Oh, *without* generating a file on the server and redirecting to it. I need direct output maybe with some neat HTTP header. :-) If it turns out there's no way, well, I'll happily keep the .r extension and be proud of it.

Can your script write out a test file, if so, where does it show up? The exists? function actually makes this determination by attempting to open a port to the file or url your specified. If opening the port results in an error it does not exist (for all practical purposes that's true as far as REBOL's concerned there)-- otherwise it does exist. Point being that other things can make it appear to not exist. -jeff Just a guess, but does the same happen if you add a trailing slash, ie: print exists? %./ Yes it does.

So, Daniel: what do you see if you do what-dir in the other script? Can you change-dir? What are the system/options/path, and system/script/path values? Can your script write out a test file, if so, where does it show up? Jeff, All the above works as intended when launched with the Rebol interpreter. However, when called from a cgi-script, a change-dir in the regular script yields : ** Access Error: Cannot open /c/winnt/. ** BTW, the same change-dir (change-dir %/c/winnt/) in the CGI script does not work neither and results in the same error. The external script runs in its own directory [system/script/path]. The CGI script runs in the cgi-bin as defined in httpd.conf (Apache on NT) In both scripts, if I write print system/options/path, I get ** Script Error: Invalid path value: path. ** Where: system/options/path daniel The exists? function actually makes this determination by attempting to open a port to the file or url your specified.

Thank you for your answer. I don't see why this would happen, as I'm working on local files with an administrator account (NT). What user does the *web server* run as?

[REBOL] New VID scroller styles...
Hi! I just finished two new styles for VID. The first one is a scroller, which is a generalization of the "slider" style found in VID. The second one is a replacement for VID's slider. The SLIDER style is almost backward compatible with VID's slider; only a minor change to your layouts should be needed if you add these styles to them: the current value of the slider is SLIDER/CURRENT instead of SLIDER/DATA. Its behaviour is different from that of VID's slider, hopefully better; the look is the same anyway. This style offers more functionality wrt VID's. It is possible to set the minimum as well as the maximum value for the slider. Examples: ... do %scroller-styles.r ... view layout [ styles scrollers ... slider ; as for VID's (from 1 to size) slider 310 ; range from 1 to 310 slider minimum 5 maximum 20 ; range from 5 to 20 ... ] ... (SLIDER is implemented as a special case of SCROLLER, so it has all of its features; the difference between the two is only in default values.) The SCROLLER style is very similar to the one found in my previous script CID-Utils.r. It is designed to be used to scroll areas. Other than the obvious minimum and maximum value parameters, it has a VISIBLE parameter that is used to specify how much of the area is visible. So, VISIBLE is the size of the visible area; MINIMUM is the value the scroller should have when the top of the area is visible; MAXIMUM is the value the scroller should have when the bottom of the area is visible. By default, the scroller comes with two arrows. It is possible to choose their position; by default they are as I like them, on both sides of the scroller. (I know some of you DON'T like them this way, but I repeat that this is just the default.) Pressing an arrow will increase/decrease the scroller's value by 5 (this can be changed too). Some examples: ... do %scroller-styles.r ... view layout [ styles scrollers ... scroller ; just a vertical scroller with arrows, going from 0 ; to 150, visible 50 scroller minimum 10 maximum 100 visible 30 ; you can guess scroller options [without arrows] ; no arrows scroller options [with arrows together] ; both arrows on the ; same side scroller options [with arrows skipping 10] ; pressing an arrow will skip 10 ... ] ... For those of you who like having the arrows together, I'd suggest defining your own style: ... styles scrollers style my-scroller scroller options [with arrows together] ... my-scroller ... ...

[REBOL] Parsing command line arguments Re:
Howdy, Garold:
Command line args that use - or + can be quoted. If you
need quotes, at least under unix, you can escape the
quotes.
Using the following script which I called "rargs":
#!/usr/local/bin/rebol -q
REBOL [Title: "Rargs"]
foreach item [
system/options/args
system/script/args
][ print [mold :item "==" item]]
You can see some examples:
rargs print \"hello\"
system/options/args == print "hello"
system/script/args == print "hello"
rargs \"+-\"
system/options/args == "+-"
system/script/args == "+-"
or...
rargs {+-}
system/options/args == {+-}
system/script/args == {+-}
If you're running under windows, I'm not sure what the

just call rebol on the script you wanted? Maybe so... Not

for shell scripts:
http://www.cs.unm.edu/~whip/rebol-unix-shell.html

Since I didnt find anything for processing command line
arguments, I decided to investigate the issue as my first
REBOL script.
I use command line programs heavily from other programs.
REBOL eats ALL arguments starting with - or
+. Since / is used in paths, it isnt
available as a flag either.
Is there a REBOL standard for option flags?
Is there a standard REBOL script for handling command line
arguments that I missed?
Any suggestions for improvements of this script?
Should I move the parse rules inside the parse-args
function?
Is there a better choice for names?
Thanks,

[REBOL] /view and the Web Re:
Since /view seems to be platform-dependent in drawing windows, is there any application for /view with Web scripting? I assume the answer is "no." -Ryan Well, Ryan, /View has all of /Core's functions as far as CGI, so you don't have to use all the GUI stuff. I likes /View but I LOVE /Core. /View has potential, it's fun to play wid. But /Core is here and now and running e-commerce aps for me like the loyal trooper it is, night and day. That's my opinion. I speak for strictly for myself here, but I think the immediate real winners from REBL are gonna be /Core and /Command. Later, I am willing predict, /View will come into its own perhaps as a part of the new e-commerce aps on the new http://rebol.com. --Ralph

Cool stuff, Ladislav! Someone's going to accuse you of
being a guru here at the rate you're going! (Or maybe
someone just did (; ) I love your "MY" function, saves
typing and works nicely with the way compose works,
allowing you to sculpt the context of words that are
executed in a block. It's wild in REBOL how a given
block of words to be executed could have words that are
bound to a million different places:
Like this silly thing comes to mind:
REBOL [Title: "Mind num'in magic"]
contexts: [a b c d e f g]
i: 0
foreach context contexts [
set context make object! compose [num: (i: i + 1)]
]
;- in this hand we have an ordinary block of
; nums.. nothing up our sleeves.. ;)
nums: [[(num)] [(num)] [(num)] [(num)] [(num)] [(num)] [(num)]]
;- allow me to fan the nums out here on the table:
forall nums [
bind first nums in get first contexts 'self contexts: next contexts
] nums: head nums
;-- Abracadabra!! Alacazoo!
; All the nums come back to you!
print [mold nums "==" mold compose/deep nums]
halt
;=
Enough silly business, though...
What happens if someone does something like this in
your secure-do, though?:
secure-do [
security: [file allow] get: func [/any][
do %bad-stuff.r
]
] 'throw [] []

Hi,
the GC problem has a work-around as can be seen below:
secure-do: func [
{secure script execution} untrusted [block! file!
string!] {untrusted script} security [block!word!]
{specify net/file policy} hidden [block!] {words to
hide} protected [block!] {words to protect} /local
my-words my result sec-do
] [
; tell GC about secure-do
sec-do: :secure-do ...
[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] /view and the Web Re:(7)
My 2 cents... I have personally been a little disappointed that /view is getting all the RT attention. This is simply because my problems are better solved with /command and who knows when that will be ready. I also wish that /core was updated as quickly as /view with new features and bug fixes. I am actively working on my own /command extensions for Win32 by using a tcp port for communication between Rebol and an EXE that will carry out commands for Rebol. I will likely make this extension public once I'm comfortable with it. I didn't want to do this but since RT is not forthcoming with a /command deadline (and additionally my request for getting a copy of /command has been ignored), I can't wait for something indeterminate. I am also working on using Rebol in web server mode so I can use a browser for UI, even though my app is running locally. I am only using the web server to get the browser interface (so that I can use form input - otherwise file display would be enough). My hope is that under Win32 you can double-click my app icon and it will load Rebol and my special EXE, pop open the default browser to the application's home page, and away you go, with most pages being rebol scripts. I have been very tempted to really rely on /view but haven't for these main reasons: 1) My company has a dictum that all new UI work be browser-based 2) I have found View to be quirky in that certain Win32 niceties aren't available (like cursor blinking, ctrl-shift selecting...) 3) Browsers currently have a richer set of possibilities including video, audio, etc. But I may be a /view convert at some point.

[REBOL] re: uppercase and lowercase
uppercase and lowercase work apparently only on any-string. But it's too bad it doesn't work on character. You can do a string or a filename, but not a single character. You can write a lower-char function that converts the char to a string then do lowercase then convert back to char again, but it seems a bit wasteful and unnecessary. I submit that making these functions work on a char and return a char is a useful and reasonable thing. Comments? galt
