04:59 <BitPuffin> When making a language that uses S-expressions inside of racket, but not necessarily perfect overlap with racket syntax, what's the best approach, is there some an extensible reader you could re-purpose or is it better to just write a new parser?

05:00 <BitPuffin> I mean I know we have reader extension

05:00 <BitPuffin> maybe I could use those

20:30 <dustyweb> YAY

20:30 <dustyweb> Goblins v0.7 released!

20:30 <dustyweb> with CapTP (distributed networked programming) support!

20:30 <dustyweb> now just waiting for the docs page to catch up so I can link to the new documentation :)

20:30 * dustyweb excited

20:54 <dzoe> Hmmm... made me look again at terminal-phase and run away quickly :)

21:06 <dustyweb> dzoe: because of the code or the game? :)

21:06 <dustyweb> it was written in a rush... though I think there are some nice things in thre

21:07 <dzoe> dustyweb: to be honest, no, the game code is fine... the dependencies are not my cup of tea.

21:08 <dustyweb> dzoe: oh, raart and lux?

21:08 <dzoe> I like neither charterm nor ansi approach to accessing the terminal for example.

21:08 <dustyweb> for the most part I just use raart

21:08 <dustyweb> which I really like

21:08 <dzoe> Which in turn uses ansi :)

21:09 <dustyweb> it does, is kind of abstracted away from me though :)

21:09 <dustyweb> dzoe: someone just sent me a HUGE Terminal Phase level today btw! I haven't had time to run it yet

21:10 <dzoe> I can understand that - but as I am fiddling with low-level stuff all the time (yes, in Racket :) ), I know it can be done better/cleaner/with less dependencies.

21:10 <dustyweb> probably :)

21:10 <dustyweb> as in, sounds likely

21:10 <dustyweb> dzoe: what's the main thing you're working on these days?

21:11 <dzoe> Well, for termios I am using my own ffi-based approach all the time. But I should really polish it and publish it.

21:11 <dzoe> For money? I am crunching some big data using parallel algorithms written with Racket futures.

21:11 <dustyweb> cool

21:12 <dustyweb> I meant in general but including for money :)

21:12 <dzoe> For fun? Software rasterizers in Racket that render ... in terminal :D

21:12 <dustyweb> whee :)

21:12 <dustyweb> dzoe: pics?

21:12 <dzoe> Not now - I finally switched to the new Unicode standard: Symbols for Legacy Computing

21:13 <dustyweb> oh there it goes

21:13 <dustyweb> yay!

21:13 <dzoe> Hmmm... maybe there are some

21:13 <dzoe> Gimme a sec

21:13 <dustyweb> https://docs.racket-lang.org/goblins/captp.html

21:13 <dustyweb> docs are updated :D

21:14 <dzoe> http://joe.cz/slc-test.png

21:14 <dzoe> Yes, those are charactes :)

21:14 <dustyweb> dzoe: oh WOW!

21:14 <dzoe> Yes, everything is absolutely default

21:14 <dustyweb> that is FANTASTIC!

21:15 <dustyweb> wow!

21:15 <dzoe> Just some clever trickery with minimizing the error in RGB space using smallest squares method.

21:15 <dzoe> As you can have only 2 colors in 2x3 character cell.

21:15 <dustyweb> dzoe: also, Terminal Phase just barely uses raart

21:15 <dustyweb> so it might be possible for me to swtich to your library

21:15 <dzoe> When I clean it up!

21:16 <dustyweb> unlike some of my other ascii art programs, for the most part it's mostly individual characters blitted to the screen

21:16 <dzoe> And that might take some time as I get easily distracted by that for money part of things :-/

21:16 <dustyweb> the other ascii art programs being https://dustycloud.org/blog/conservancy-card/ https://dustycloud.org/blog/lets-just-be-weird-together/

21:18 <dustyweb> dzoe: what's the pixel art from btw?

21:19 <dustyweb> the pixel art transposed to unicode characters I mean, of course

21:21 * dustyweb wonders how dzoe is rendering so many different colors on one "character"

21:23 <dzoe> dustyweb: 32x32 tiles for use in ADOM from http://pousse.rapiere.free.fr/tome/

21:24 <dzoe> It's not "many", it's 2 (two).

21:24 <dzoe> It's just that if you pick the right two, it tricks the human eye easily.

21:25 <dustyweb> right :)

21:26 <dzoe> dustyweb: http://joe.cz/tmp/tut24-screenshot.png - this is the state of 3D rasterizer (pure Racket) from May. That is canvas% backed.

21:27 <dzoe> The goal is to back it with SLC glyphs and 256-color / 16M-color ANSI extensions.

21:27 <dustyweb> interesting!

21:29 <dzoe> Btw, nice ASCII/ANSI animations you have there :)

21:29 <dzoe> I was never that patient to actually do something like that. That's why I stick to generating everything using some math formula.
