08:10 <hunar> Hello :) I checked out OOP in Pil and I have two questions: I made this https://pastebin.com/tM279n0E ... when creating objects, what is the difference between (new '(+Ball)) and (new +Ball) , and I wanted to call the method constrain> within the method update> but couldn't figure out how

08:12 <Regenaxer> Hi Hunar!

08:12 <Regenaxer> (new +Ball) is not correct, 'new' needs a "Type" which is a list of classes

08:13 <Regenaxer> You can call (update> This) inside the method

08:17 <hunar> Thanks :D didn't know This

08:17 <Regenaxer> ok

08:17 <Regenaxer> 'This' is a normal symbol, automatically bound inside methods

08:18 <Regenaxer> or explicitly with (with (xxx) ... This ...)

08:22 <Regenaxer> So what (new +Ball) actually does is (new NIL)

08:22 <Regenaxer> cause +Ball has no (super)class(es)

09:58 <razzy> Good day i wish to all! I solved my (in) troubles. I think PilCon about (in) (out), streams, files handling, would still have value for me.

09:59 <Regenaxer> razzy, your problem was not specifically 'in'

10:00 <Regenaxer> You do perhaps not understand how evaluation works?

10:00 <razzy> Question: do we have function that print string into pil-REPL-command-line but does not eval it? "without pressing enter"? So i can manually edit it?

10:01 <razzy> Regenaxer: my problem was that i did not read (doc 'in) enough. and i did not expect so many functionality in (in)

10:01 <Regenaxer> ok

10:06 <razzy> Regenaxer: do we have function that print string into pil-REPL-command-line but does not eval it? "without pressing enter"? So i can manually edit it and than send with enter?

10:09 <Regenaxer> This question makes no sense to me

10:10 <razzy> Regenaxer: thank you, no problem. i think i found workaround

10:35 <razzy> just curious, Why is (history) compiled function and not global list *History?

10:35 <Regenaxer> It is *inside* readline(), not in PicoLisp

10:37 <razzy> ah i forgot. thank you. sorry

10:38 <razzy> written as note for future me!

10:39 <Regenaxer> :)

11:20 <hunar> Thanks Regenaxer :) I was very busy and couldn't reply ... one more question.. I tried to dynamically get the terminal resolution with (call 'tput "lines") but tput lines only prints the result, not returning it.. How can I get the printed result

11:21 <Regenaxer> With a pipe: (in '(tput "lines") ... (line T) or (read) etc. )

11:22 <hunar> That worked :D thanks

11:22 <Regenaxer> :)

11:35 <Regenaxer> In Vip I first also used tput

11:35 <Regenaxer> But now I think I do all by "hand"

11:36 <Regenaxer> Lines and colums are retrieved by an "ioctl" call

12:01 <hunar> I just googled ioctl and didn't understand how to use it :/ ... By the way, since you know muuuch more than me, what do you suggest someone use if they want to draw ascii graphics fast, something like this https://www.youtube.com/watch?v=DEqXNfs_HhY

12:01 <hunar> Is tput fast enough?

12:03 <Regenaxer> The animation in the video is very fast! No way with tput, you need to write directly into the framebuffer

12:03 <Regenaxer> PilOS does something like that

12:03 <Regenaxer> Directly writes chars into video memory

12:04 <Regenaxer> tput is very slow, as it starts a procees each time

12:04 <Regenaxer> Vip is in between, it writes to the terminal window

12:05 <Regenaxer> 'prin' basically

12:05 <Regenaxer> and does cursor movements with escape sequences

12:05 <hunar> what should I read to get more familiar with (write directly into the framebuffer) :) Is it done with a library?

12:05 <Regenaxer> "Vip is in between" in terms of speed I mean

12:06 <Regenaxer> Yes, there are libraries, but I have never investigated

12:06 <Regenaxer> PilOS is low level, so there it is easy

12:06 <hunar> Cool :)

12:06 <Regenaxer> Do you need such fast animations?

12:07 <hunar> I don't need it actually.. just curious how people do stuff

12:07 <Regenaxer> good :)

12:10 <Regenaxer> Another example is perhaps rcsim

12:11 <Regenaxer> It writes directly to an XWindow

12:11 <Regenaxer> https://software-lab.de/rcsim.tgz

12:12 <Regenaxer> (I think you know it)

12:12 <hunar> I saw it before :) it's amazing .. but didn't understand (writes directly to an XWindow) that is different than opengl right?

12:12 <Regenaxer> yes, it does not use any library like OpenGL

12:13 <Regenaxer> Directly draws pixels

12:14 <hunar> I'll try running it now :)

12:14 <Regenaxer> ok

12:20 <Regenaxer> hmm, maybe I messed it up?

12:20 <Regenaxer> The key controls are for Penti now

12:20 <Regenaxer> I hope I did not release that (?)

12:22 <Regenaxer> Seems I did :(

12:30 <Regenaxer> What can we do next PilCon?

12:30 <Regenaxer> Day after tomorrow morning

12:34 <hunar> How can I run the rcsim? I copied the library to pil21/lib and run :pil misc/rcsim.l -go it keeps printing ? !? (sim> *Scene)

12:34 <hunar> sim> -- Bad message

12:35 <Regenaxer> You need also -main

12:35 <Regenaxer> ./pil misc/rcsim.l -main -go +

12:35 <hunar> Oh, I didn't realize 10th Sep is that soon :/

12:36 <Regenaxer> yeah, me too

12:36 <hunar> It's running :) what are the controls?

12:36 <Regenaxer> Do you have time to attend?

12:36 <Regenaxer> It is Friday, your holiday :)

12:37 <Regenaxer> The controls are the probleon

12:37 <Regenaxer> problem

12:37 <Regenaxer> I did something stupid

12:37 <Regenaxer> changed them

12:37 <Regenaxer> At the end of rcsim.l

12:38 <Regenaxer> "+" "-" etc.

12:38 <Regenaxer> It used to be keys from the numpad

12:38 <hunar> My life is kinda complex right now, I'll see my first child next month :) I'll try to attend it, but I may not talk (mic and camera) because my laptop has a horrible webcam and a broken microphone.. how to attend by the way?

12:39 <Regenaxer> No problem! Congrats for your child!! :)

12:39 <hunar> Thanks :D

12:40 <Regenaxer> Lets postpone rcsim for the moment? I don`t have access to the old version here

12:41 <hunar> Ok :)
