World: r3wp

It used to be just strings that were hashed. Other data types were 
just sitting there, and had to be found with a linear search like 
with other blocks.

I vaguely recall that they later started hashing some other datatypes, 
but can't recall which ones.

Is there a  Perl compatible regular expression parser written in 
REBOL

note to volker:   what did I say  !!!!  ;-)


I was just telling volker privately, a few hours ago, how having 
regexp within REBOL would help those who migrate to it  ;-)

Joe, not that I know of.   Try to learn the 'Parse word.  There are 
a lot of parse experts hanging on this site... (not that I am one 
of them..)

Yep, parse is great.

is there a way to set the datestamp when writing a file?

Try set-modes: 
http://www.rebol.com/docs/words/wset-modes.html
http://www.rebol.com/docs/words/wget-modes.html

>> port: open/binary %xml-object.r
>> set-modes port [creation-date: 1-Dec-2004 ]
** Access Error: Cannot open /D/rebol/rebXR/xml-object.r
** Near: set-modes port [creation-date: 1-Dec-2004]

What about 
   set-modes %xml-object.r  [creation-date: 1-Dec-2004 ]
But may not work on windows -- not all modes are supported.

no, doesn't work either.

hey, that works !

I still had the port open so the first attempt failed

kewl.

Larry's list of RegEx shortcomings http://www.perl.com/pub/a/2002/06/04/apo5.html?page=2

24 pages of problems ??

it's a start ...

I'll sleep better tonight now :)

Does one say what is the syntax to specify parity on a serial port 
?

I saw "parity: none" on docs, but what does it mean, even or odd 
? And so what is the other syntax (odd or even) "parity: ????"

'none means "no parity". parity: 'odd or ' even should work fine.

port/update should be applied after the change IIRC ...

So I can use 'odd or 'even in the URL  ?
Ie :
	open  serial://port1/9600/8/even/1

not sure ...

will try ;-)

but maybe so, as you can use /none/1

Seems to work ! Thanks

I also set rts-cts: off

I am not sure if rebol serial ports do work without that. I wanted 
simply my rebol tool to find our device on whatever port (autoscan) 
and it imo hangeg the app, even if I used open/direct/no-wait

WRT RegEx's -- I did a simple wildcard matcher (emulates VB's Like 
operator), and looked at hooking up PCRE, but it had a funky interface 
to it and I didn't get it working in the limited time I spent on 
it.

Is it possible to set the modification date on a directory?  I keep 
getting errors whereas it works with files in win32.

>> set-modes %xml-parse.r [ modification-date: 1-Jan-2005 ]
>> set-modes %www/ [ modification-date: 1-Jan-2005 ]
** Access Error: Cannot open /D/rebol/rebXR/www/
** Near: set-modes %www/ [modification-date: 1-Jan-2005]
>> set-modes %www [ modification-date: 1-Jan-2005 ]
** Access Error: Cannot open /D/rebol/rebXR/www
** Near: set-modes %www [modification-date: 1-Jan-2005]

I think I remember getting the same error with directories.

Shame ...

I am writing this file/directory replication tool, and I want to 
preserve the dates on the newly created directories

Well, I am stuffing around with files in C at the moment. I will 
see if it can be done with Windows api.

that would be cool.

(go to Windows group)

Graham I did something similiar which allows me to write the date 
to another target just as it appears in the original - kinda like 
a backup.  However, I need to modify it so that the target dates 
are stamped as they are originally.  Currently it changes the stamp.

Have you looked at Bo's LTC-Backup application that is on Developer?

http://vbnet.mvps.org/index.html?code/fileapi/folderdatetime.htm
for visual basic, googled "windows change directory date api"

can zip do it?

>> to-block %test
== [test]
>> to-block %test/
** Syntax Error: Invalid path -- test/
** Near: (line 1) test/

>> b: copy [] insert b %test/
== []
>> b
== [%test/]

file! is an any-string and thus sourced. probe to-block %"1 + 2"

only usable for loading from strings, or with some caution IMHO.
  probe to-block mold/only %test/

Hi, is it possible to restore the date of a file which was read via 
ftp?

How about not using ftp and try Coyote :)

>> foo: [a [does this]]
== [a [does this]]
>> bar: [b [does that]]
== [b [does that]]
>> rejoin [foo bar]
== [a [does this] [b [does that]]]

Is there an equivelant function that would give me:
== [a [does this] b [does that]]

>> A: []
== []
>> insert A bar
== []
>> insert A foo
== [b [does that]]
>> ? A
A is a block of value: [a [does this] b [does that]]

Yep, I can fudge it that way, but I was looking for a single function, 
like 'rejoin or 'reduce

Or, if you don't mind changing 'bar:
>> insert bar foo
== [b [does that]]
>> ? bar
BAR is a block of value: [a [does this] b [does that]]
