World: r3wp

Thanks for the enlightenment, Cyphre

Cyphre - so why not to fix that system port bug?! That would be nice, 
as old (pre R3) SDK could have fixed that bug

I have already posted the bug into RAMBO so it depends on Carl's 
decission now.

will system port exist in R3, or it will be done in other way?

You need to ask Carl, but I think system port should be in R3 too.

Can somebody explain to me, how does FIND work in file! ?

>> path: %/disk/drawer/
== %/disk/drawer/
>> file: %/disk/drawer/file
== %/disk/drawer/file
>> find/match file path
== %file
>> find/match file %/disk
== %/drawer/file
>> find/match file %/disk/
== %drawer/file
>> find/match file %disk/
== none
>> find/match file %drawer
== none


It seems to work only if the searched string stars on begining of 
file!

That's right, the /MATCH refinement causes exact matching to occur 
from the position you specify (eg. the start). I was a bit confused 
by this at first too. What you probably want is the /ANY refinement, 
which switches on wildcards. So use /ANY instead of /MATCH and you'll 
be alright.

There's nothing special about FIND's treatment of FILE! datatype 
here. It's just another any-string!

I'm using /MATCH because I want to strip part of path. I'll probably 
make parse rule for it :/

Ah.. maybe you want FIND/ANY/TAIL

or just FIND/TAIL

Anton great, that's exatly it!

Cyphre, where is this documented?

You can also use the API to get the current keyboard state, whether 
or not you trap the key yourself. And, yes, if we ever get system 
ports working under View, it will be nice; for file drops alone it 
would be great.

About the numLock and capsLock, the problem is solved. In ActionScript, 
there are "flash.ui.Keyboard.numLock" and "flash.ui.Keyboard.capsLock". 
I am programming my GUI using ActionScript and my engine using REBOL. 
And ActionScript and REBOL talk to each other through sockets.

Cool.

Maxim: AFAIK the only info about system port I know is here:
http://www.rebol.com/docs/changes.html#section-5.10and 
and also Gregg's script at rebol.org:

http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=sys-port-drag-accept.r

my god... how can such a big feature pass by virtually unused...

I didnt even know about the system port being something we could 
program.

I was asking and ranting about being able to accept OS events ... 
and IIRC no one droped this on me !

Max, you're always ranting maybe!? ;-P (joking)

hehhee

I'm the Canadian Pekr  ;-)

what? hehe :-)

I wan't my x-mas present NOW! .... oh, wrong channel... ;o)

hahaha

maxim lol :)))

More info on the abilities of system port would be great - till then 
ill experiment with it to see just what its range is under windows..

If Carl is still writing learner docs, perhaps he could finally document 
the system port.

Under Windows, you can trap pretty much any WM IIRC, but you can't 
do it from a View window, which is the big limitation. Still useful 
for some things though.

Eh ?

the system port can't be used for drag and drop and View faces?

Nope.

At least I could never get it to work.

Hope this is rectified in r3

what's the fastest way to sort a directory of files chronologically?

This needs 'foreach-file from rebol.org

>> include %foreach-file.r
>> out: copy [] ff: func [file][repend out [file modified? file]]
>> foreach-file %./ :ff

== [%./!/basics_wide_desktop_computer_system.xml.ttx 21-Jun-2006/16:05+1:00 
%./!/basi
cs_wide_hard_disk_drive.xml.ttx 21-Jun-2006/8:...
>> sort/skip/compare out 2 2

== [%./ft/wavs/balloon.wav 23-Aug-2001/13:00+1:00 %./ft/wavs/down.wav 
23-Aug-2001/13:
00+1:00 %./ft/wavs/error.wav 23-Aug-2001/13:00...

thanks

Hmmm, has anyone looked at my FILE-LIST script on REBOL.org? If so, 
would it make sense to add an option to sort the results, or an option 
to have extra data returned (e.g. attrs or date-time) along with 
the file names themselves?

; version 1
my-face: make face [
    my-data: none
]
make-my-face: func [ extra-data ] [
    make my-face [ 
        my-data: extra-data 
    ]
]
; end of version 1

; version 2
my-face: make face [
    my-data: none
    new: func [ extra-data ] [
        make my-face [ 
            my-data: extra-data 
        ] 
    ]
]
; end of version 2


Quesion: I have a lot of my-face objects ( 1,000,000+ ) in an appication. 
Which version is better? Will the version 2 take more memory since 
the "new" is a object method instead of a function?

1 million objects?  how much RAM is that taking?

It depends. Every my-face shows an Unicode character bitmap. They 
are put in a pool for saving memory. If a character is not needed, 
it won't be loaded. ... Showing a long article wich Chinese character 
in it is a nightmare. Short article is not a problem though.

why don't you simply use AGG to "stamp" each character in a bitmap? 
 using the draw command over and over (per character or per line)

this can limit your memory use a lot! especially if you do a pre 
analysis and count the recurrence of each character in the article 
(so you can keep only those that recur, saving some speed).

I guess some of this is what you already do...

version 2 definitely takes more memory.

With v2 that object method will be copied to every object. The factory 
function approach you use in v1 is better.

And with that number of objects, if you can use blocks instead of 
objects, it will reduce the weight even more.

but notice he is creating faces... can't replace that with block 
 !

it's possible to replace it with block, when you create draw dialect 
instead of pane of faces
