 I am stuck.  I have followed along with the "Simple Database" contained in
the Rebol how-to.html file, but I can't manipulate the header object that
save/header load/header creates. I want to make changes and save the data
back, with the header intact.

This should work:
save/header %cities2.r data header
BUT it doesn't work correctly as there's a bug in 'save! Have a look at
REBOL/View's help for 'save:

 help save
USAGE:
SAVE where value /header header-data

DESCRIPTION:
 Saves a value or a block to a file or url.
 SAVE is a native value.

ARGUMENTS:
 where -- Where to save it. (Type: file url)
 value -- Value to save. (Type: any)

REFINEMENTS:
 /header -- Save it with a header
 header-data -- Header block or object (Type: block object)

With the refinement /header and using an object, 'save saves the data like
this:

 print read %cities2.r
REBOL
make object! [
Title: "City data"
Date: none
; SNIP!
Language: none
User_Groups: "PDX Vanc"
]

Note that "make object!" shouldn't be in the REBOL script file!

Here's a quick example:

 h: make object! [
[File: %file.r
[Date: 7/April/2000
[]
 data: [
[a: 1
[b: 2
[c: 3]
== [
a: 1
b: 2
c: 3]
 save/header %file.r data h
 print read %file.r
REBOL
make object! [
File: %file.r
Date: 7-Apr-2000
]

a: 1
b: 2
c: 3

Note that "make object!" shouldn't be in the 'save-ed file!

CC-ed to feedback and to ally list.

[REBOL] Newsletter via Procmail Re:

2000-04-07 Thread bpaddock


My web host supports REBOL and limited procmail but not SMTP (direct outgoing
mail).


Do a search in http://www.simtel.net/simtel.net/ .

I've seen a program there that will act as a SMTP server on
your local machine so that the ISP is not involved with
sending the mail on their server.




[REBOL] Thanks for advice on: Salvaging ASCII data from binary file

2000-04-07 Thread geddes

Thanks to everyone who responded. I used Allen K's advice:

good-chars:  charset  [#" " - #"/" #"0" - #"9" #"A" - #"Z" #"a" - #"z"]
file: to-file ask "Filename? "
data: read/binary file
forall data [
if find good-chars first data [
write/append %good.txt to-string copy/part data 1
]
]

This worked fine. The file was an Access database (Jet Engine) which got
corrupted when someone opened it in MS Word and overwrote it. Originally,
it was thought someone put a password on it. Of course, the ASCII version
looks like a mess, but the names, phone numbers, etc. are readable. Of
course, these people didn't have a recent copy or backup of the file.

Mark Evans suggested using Icon - which looks good; Michael Jelinek
mentioned using "strings" if I had Unix (I'm using Win95; I do have the MKS
toolkit, but not currently installed); Bob Paddock sent me a little program
(strip.exe) to clean the file. Of course, Euphoria or Snobol4 would
probably work well, too.

Rebol seems the simplest - nice for a little job like this.

[REBOL] CGI secure WAS: CGI problem

2000-04-07 Thread mailinglists

Hello Ingo,

   #!rebol -cs
   REBOL[]
   secure [net quit]
  
   This would give all access to files, but none to the web.

 Well, I just tried to answer the question, in te way I understood
 it. I think GET should still be possible, I am not sure about PUT.
 (I have written one test cgi up to now, so am not exactly a profi
 in this field).

 Thinking about it, the better solution would be to add 'secure
 to %user.r, know you could be sure, that none of your cgi's ever
 sends a mail with your files attached, or something like that ...

Uhm, but that would only count if you used your general Rebol for CGI, and
on a web server, you usuallyu don't (I wouldn't!), my web server has Rebol
in the /cgi-bin/ without a user.r, so it can't mail anyway...

I will test the 'PUT' this weekend... (don't you mean POST?)

Regards,
Rachid




[REBOL] bug ? parse / space Re:(3)

2000-04-07 Thread mailinglists

Hello,

 When I use the '| operator (for OR), 'parse will search the entire string
 for the first pattern then, if this isn't found, it will begin searching
for
 the second pattern. Although a person may want to do this, I do not. What
I
 want is to match the first or second pattern, WHICHEVER COMES FIRST in the
 search string. Bummer, huh?

I couldn't verify this (I only got 'true' returned, but that's obvious ;o),
but I believe 'any is what does that precisely:

a: "ads1dgfuihdf2iofj6pfg5idgfi6idfsgp7gfhi8"
parse a [any ["5" "6"] to end]

My mastery of parse doesn't extend to actually proving this, but I believe
this means 'parse stops at the first of the two it encounters, just like you
wanted, right? =)

Regards,
Rachid
