01:44:16 <tangentstorm> hey impomatic  :)
01:45:56 <impomatic> Hi tangentstorm. How's it going?
01:46:53 <tangentstorm> going alright... working on a pascal -> retro/ngaro compiler
01:46:55 <tangentstorm> yourself?
01:54:21 <impomatic> All fine... I'm not actually working on anything, but considering a few ideas :-)

11:02:46 <Mat2> good day 
11:05:13 <Mat2> tangentstorm: you will find my VDP code in the backport directory (romVDP.pas)
11:06:08 <Mat2> tangentstorm: together with test.pas for testing
11:09:45 <Mat2> two bugs need to be fixed, the font is rendered mirror and attributes are not correct processed
11:11:24 <tangentstorm> Mat2: awesome! i'm just wrapping something up. i'll take a look in just a few minutes! :)
11:12:19 <Mat2> I will fix the remaining issues today after work (in one ore two hours)
11:13:04 <Mat2> but you can take a look (it's fast)
11:13:33 --- nick: Mat2 -> Mat2-at-work
11:50:50 --- nick: Mat2-at-work -> Mat2
12:01:18 <Mat2> tangentstorm: font rendering is now fixed
12:04:37 <tangentstorm> Mat2: aww :/ I was trying to figure out to send you a patch :)
12:04:53 <tangentstorm> it looks nice, even backwards :)
12:06:37 <Mat2> thanks
12:07:06 <Mat2> the last bug remain is the processing of colour attributes
12:08:14 <Mat2> hmm, this seem to be a compiler bug, I need a work around
12:11:34 <tangentstorm> can you describe the problem ?
12:12:44 <tangentstorm> test.py doesn't exit for me on winxp... it just sits there ( i suspect crt.readkey and sdl are conflicting with each other )
12:12:47 <Mat2> only 128 colours are visible and instead of changing the foreground colour of a tile the background colour is changed
12:14:07 <tangentstorm> how rude
12:14:09 <tangentstorm> :)
12:15:40 <Mat2> *lol* ok, SDL map only 128 colours in 8-bit modes (have someone ever used this modes before me?)
12:21:31 <Mat2> so, problem fixed
12:23:20 <Mat2> the palette for 256 colour mode is duplicated for the upper 128 colours with changed intensity values so there are really two 128 colour palettes
12:24:52 <tangentstorm> merge request submitted
12:25:10 <tangentstorm> weird
12:28:01 <Mat2> ???
12:29:30 <Mat2> ok, the fixed source is now online
12:29:58 <Mat2> you can't merge my repro ?
12:31:08 <tangentstorm> yep, i can
12:31:19 <Mat2> :)
12:31:27 <tangentstorm> the request is for you to pull my changes in :)
12:31:59 <tangentstorm> i don't know what it looks like from assembla... you should have a message or something on there
12:32:09 <Mat2> hmm, nope
12:33:21 <tangentstorm> https://www.assembla.com/code/avm/git/reviews#open
12:33:48 --- quit: impomatic (Quit: http://programminggames.org)
12:34:51 <Mat2> thanks, my connection is somewhat slow
12:35:24 <Mat2> I have a notification with your request
12:37:38 <Mat2> ok, merged your changes :)
12:37:57 <Mat2> thanks
12:38:35 <tangentstorm> np :)
12:39:08 <tangentstorm> oh pretty colors
12:39:55 <tangentstorm> i think i will try porting this: https://github.com/sabren/b4/blob/master/xterm256color.pas
12:43:35 <Mat2> I have found no more bugs, the code works well
12:44:30 <Mat2> are the ng-*.pas files in your repro your ngaro version ?
12:45:18 <tangentstorm> Mat2: yep. retro.pas is the command line interface. ng.pas is the main file for the vm, and it includes the others.
12:47:54 <Mat2> ok, I replace the terminal functionality
12:52:49 <Mat2> do you need ANSI and vt100 terminal emulation support (for xterm256colour.pas for example) ?
12:54:05 <tangentstorm> i already have a library that does all that somewhere around here
12:54:13 <Mat2> ok
12:54:19 <tangentstorm> maybe not vt100
12:54:26 <tangentstorm> i guess i should make a list :)
12:54:32 <Mat2> yes
12:55:00 <tangentstorm> i definitely want this to run on the terminal / console as well as in graphic mode
12:55:49 <tangentstorm> in fact... i was kind of thinking i might make two completely separate executables : a terminal app with no vm, and a vm that just output ansi/xterm escape codes
12:57:02 <Mat2> so you can now program a SDL terminal program :)
12:57:57 <tangentstorm> yeah! this is awesome :)
12:58:14 <tangentstorm> http://en.wikipedia.org/wiki/Remote_imaging_protocol
12:58:19 <tangentstorm> was kind of thinking of doing something like this
12:59:47 <Mat2> In germany a similar (lisp based) protocol was used for the national BTX net
13:00:25 <tangentstorm> there were a number of protocols like this, i think.
13:00:46 <tangentstorm> ripterm was sort of a general purpose bbs client. i know a lot of people who used it but nobody who ever used the graphics :)
13:02:00 <Mat2> weird
13:02:58 <tangentstorm> i think the graphics stuff was being developed just as BBSes were losing popularity. <shrug>
13:04:46 <Mat2> there exist here some non public networks for people which do not want to use the internet, mostly programmers
13:05:35 <Mat2> so BBSes are still somewhat popular
13:06:05 <Mat2> there problem is the bandwidth I think
13:06:25 <tangentstorm> there are actually a bunch of BBSes you can get at through telnet too
13:06:51 <tangentstorm> when i first got into retro, i was trying to make a console style game with ansi graphics... there's actually a pretty thriving ansi art scene still :)
13:07:45 <Mat2> I know the demo scene a bit, the last text-style art I saw was a demo for the famous ZX81
13:10:09 <Mat2> this one: http://www.youtube.com/watch?v=X92xvLlbnVg&feature=relmfu
13:12:12 <Mat2> not really ASCII art because sinclair used a non ASCII compatible encoding
13:14:02 <Mat2> (and no colours so no ANSI support)
13:14:28 <Mat2> but nice
13:18:37 <tangentstorm> haha cute
13:19:43 <tangentstorm> pablodraw is the ansi art / paint program that seems to be the big thing now... it has built in networking so many people can all draw together
13:21:00 <Mat2> good to know such programs :)
13:21:19 <Mat2> ok, I compiled retro.pas and get a stack underflow error
13:21:55 <tangentstorm> well, I never!!
13:22:16 <tangentstorm> hopefully it's an ngaro underflow, right?
13:22:28 <tangentstorm> you can run retro -d   to get the debugger
13:22:53 <tangentstorm> no breakpoints yet, but it has an extra opcode .. 31 triggers the debugger i think
13:26:59 <Mat2> are you compiling 32 bit or 64 bit code ?
13:27:14 <tangentstorm> 32, afaik
13:28:01 <tangentstorm> Mat2: is it the pc stack or the ngaro stack that's underflowing?
13:28:07 <Mat2> the ngaro stack
13:28:36 <tangentstorm> is it happening in the help screen?
13:28:51 <Mat2> at startup, yes
13:29:00 <tangentstorm> retro.pas and retro.py both crash when you run that color help
13:29:10 <tangentstorm> oddly, retro.c doesn't
13:29:19 <tangentstorm> i haven't figured out what's different yet
13:30:16 <tangentstorm> probably the vt.rx code isn't doing things exactly the right way, but i don't know why the three vms all have different issues
13:30:32 <tangentstorm> ( retro.py and retro.pas both crash, but not in the same place )
13:30:53 <tangentstorm> if you use the retro 11.5 image that crc's made it will probably work better
13:31:09 <Mat2> ok, I will take a look
13:35:03 <Mat2> the retro 11.4 image work well
13:40:05 <tangentstorm> :)
13:40:36 <tangentstorm> I'm really tired and juggling too many things right now.
13:40:41 <Mat2> ok, now I have a testbed for implementing the VDP code
13:40:50 <tangentstorm> I will make a bug/issue list.
13:41:08 <Mat2> that's needed
13:41:21 <tangentstorm> Mat2: you may also want to look at https://github.com/badsector/ptckvm
13:42:13 <tangentstorm> the "video" module is sort of the modern replacement for crt in freepascal that all the console apps use
13:42:34 <tangentstorm> it doesn't have 256 color support though
13:43:30 <tangentstorm> i don't really have a use for it or anything, but it might be handy for reference or something
13:43:38 <Mat2> thanks, I will take a look
13:44:03 <tangentstorm> actually, that badsector guy has a bunch of really cool programs
13:44:22 <tangentstorm> he has a pascal audio/soundsystem i was thinking of stealing
13:44:36 <tangentstorm> all zlib license too
13:44:57 <tangentstorm> and a haxe version which i believe should compile to javascript
13:45:07 <Mat2> nice
13:45:08 <tangentstorm> for a retro music / midi device
13:45:50 <Mat2> I will take some sleep and finish coding tomorrow
13:47:29 <Mat2> text display works but need some modifications
13:48:53 <tangentstorm> me too. i've been up way too long. talk to you later :)
13:49:06 <Mat2> see you later :)
