Geomol 28-Nov-2006 [6425] | I wan't my x-mas present NOW! .... oh, wrong channel... ;o) |
Maxim 28-Nov-2006 [6426] | hahaha |
Rebolek 28-Nov-2006 [6427] | maxim lol :))) |
ICarii 28-Nov-2006 [6428] | 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.. |
Graham 28-Nov-2006 [6429] | If Carl is still writing learner docs, perhaps he could finally document the system port. |
Gregg 29-Nov-2006 [6430] | 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. |
Graham 29-Nov-2006 [6431x2] | Eh ? |
the system port can't be used for drag and drop and View faces? | |
Gregg 29-Nov-2006 [6433x2] | Nope. |
At least I could never get it to work. | |
Graham 29-Nov-2006 [6435] | Hope this is rectified in r3 |
Henrik 29-Nov-2006 [6436] | what's the fastest way to sort a directory of files chronologically? |
Rebolek 29-Nov-2006 [6437] | 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... |
Henrik 29-Nov-2006 [6438] | thanks |
Gregg 29-Nov-2006 [6439] | 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? |
Jerry 14-Dec-2006 [6440] | ; 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? |
Maxim 14-Dec-2006 [6441] | 1 million objects? how much RAM is that taking? |
Jerry 14-Dec-2006 [6442] | 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. |
Maxim 14-Dec-2006 [6443x3] | 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... | |
Gabriele 14-Dec-2006 [6446] | version 2 definitely takes more memory. |
BrianH 14-Dec-2006 [6447] | With v2 that object method will be copied to every object. The factory function approach you use in v1 is better. |
Gregg 14-Dec-2006 [6448] | And with that number of objects, if you can use blocks instead of objects, it will reduce the weight even more. |
Maxim 14-Dec-2006 [6449] | but notice he is creating faces... can't replace that with block ! |
Rebolek 14-Dec-2006 [6450] | it's possible to replace it with block, when you create draw dialect instead of pane of faces |
Gregg 14-Dec-2006 [6451x3] | Right, to clarify, if your my-face object has other overhead that could be externalized, do that, and use blocks that contain a reference to the lightest-weight face you can use. |
Yes, even better rebolek. | |
It's exciting to see someone pushing REBOL this way though! | |
Rebolek 14-Dec-2006 [6454] | placing bitmaps with draw is possible even in non-AGG versions of View |
Maxim 14-Dec-2006 [6455] | do you think such a big draw block will hold? |
Rebolek 14-Dec-2006 [6456] | hm, not sure, but you can have one face per line (or column - don't know which direction Jerrry uses :) filled with draw block |
Maxim 14-Dec-2006 [6457] | well, I guess it depends on exactly what he is outputting... but by what I understand, the display is less an issue than the actual loading of all the characters. |
Rebolek 14-Dec-2006 [6458x2] | if he's just loading characters then keeping images in block is definitely better |
you can have block like this: [unicode-number image! unicode-number image! ...] and then just use SELECT | |
Maxim 14-Dec-2006 [6460] | yep. |
Jerry 14-Dec-2006 [6461] | Thank you for all your comments. I'll try them out. |
Graham 16-Dec-2006 [6462] | How about a /native refinement to return files in 'request-file to return files in the native file format? |
Anton 17-Dec-2006 [6463] | Why not just write a TO-LOCAL-FILES function to do that for all files in a block ? |
Graham 17-Dec-2006 [6464x4] | because it means I could do this |
show-text field form any [ request-file/only/native copy "" ] | |
and not get "none" in the field | |
umm.. let me rephrase that! | |
Anton 17-Dec-2006 [6468] | >> form to-local-file any [%hello %""] == "hello" >> form to-local-file any [#[none] %""] == "" |
Graham 17-Dec-2006 [6469x3] | form any [ to-local-file request-file/only/native copy "" ] |
form any [ to-local-file request-file/only copy "" ] | |
which errors if request-file returns none | |
Anton 17-Dec-2006 [6472] | This doesn't: form to-local-file any [request-file/only %""] |
Graham 17-Dec-2006 [6473] | ahh.. :) |
Anton 17-Dec-2006 [6474] | Too easy, eh ? |
