If it were up to me I'd just the first magic number there. Maybe add it to the seed if you're feeling adventurous.

>>106827819
On my machine it has no usecase.

using u8 = unsigned char;
using u16 = unsigned short;
using u32 = unsigned int;
using u64 = unsigned long;
using u128 = __uint128_t;

using i8 = signed char;
using i16 = signed short;
using i32 = signed int;
using i64 = signed long;
using i128 = __int128_t;

using f32 = float;
using f64 = double;
using f128 = long double;

Thanks to the anons in previous thread, my dynamic array of Polygons which may contain dynamic arrays of Polygons ad-infinitum is working good enough for now. Using indexes for everything now instead of pointers, so it doesn't matter if realloc moves memory.

Sad to say, Tcl/Tk is the only good GUI library. Things only ever went downhill from there.

At least it's still maintained to this day by dedicated and active core team, no matter how much everyone tries to gaslight you that it's "deprecated" and "looks old" or whatever other crap people try to say about it

how
you just interpolate geometry between two states with time

>>106829616
Not that exciting, huh?

>>106829869
It's a declarative library, so by calling the api functions you're basically building the node tree that you want for that frame. Before, there was just that one tree. But now because of the exiting animations, nodes should be able to stick around inside the real tree for a while, even if they are not part of the declared tree. So I have to rewrite some stuff to account for this.

>>106830471
that looks like a bad api design to me
it's no longer declarative if the definition doesn't match the visual
a better api would let the user toggle the tree as hidden which triggers the hiding animation
then add/delete elements while it's hidden after it receives animation completion event

tcl/tk would be good but it has too many weird quirks and the text widget is just slow.

I'm currently writing my own PNG decoder in C, lol. It's been a while since I've had this much fun programming. Reading the specification and figuring things out. Yeah... that's life. *unzips beer*
Now I'm debating whether I should implement my own deflate implementation or use zlib... Might as well go all in, right?

>>106830966
I was writing something like that not long ago after doing CS50. And yeah, it was not only fun, but truly "empowering" so to speak.
It was my first time writing code that was not simple terminal baby projects, or simple webdev shit. Dealing with raw bytes and interpreting the data, working with PNG chunks and shit, it was amazing.
I was doing it in C as well and then translated the program to Rust just because.
I abandoned the project precisely after the deflate implementation, though. Got somewhat bored, ironically.

>>C API

>>no ebussy
Of course for the C API but it's irrelevant.

I'm talking about how it interacts with the underlying GPU API (OpenGL, Vulkan, ..).
If it allows you to talk to it directly?
how are widgets are compiled to GPU primitives?
can you put GPU rectangle/quads inside a widget (ex: a font library generates quads)?
does the GPU or does the GUI library does Z-sorting of the widgets?
how are events handled?
what does the GUI library state and data structures looks like?

ImGUI C-API is a horrifying mess.

>>106829468
Apache libraries are easy to use if you know the data format you're working with
just look up how the PDF format works, then the Apache lib should be basically self-explanatory

Hey /g/, you're stuck with a terminal with no commands. No vi, emacs, nano, grep, echo, sed, mv, ls or even cat. But you gotta edit this file!
Thankfully, you got your trusty le - pure POSIX sh builtin line editor, which works in every single POSIX compliant shell, even the ones with absolutely NO external commands!

I wondered what could be done with pure POSIX sh builtins, meaning absolutely no commands like ls, mv, rm, touch etc. So I made a simple line editor with command/pipe capabilities.

Instead of worrying about variable size limits, it simply uses temporary files as buffers.
Files are created with :>, copied around by simply looping < "$file", everything works on current selection or other line numbers if provided. There's also janky teletype mode simply for the reason that I wanted to avoid the screen clear and other escape sequences.

It could be tidied up a bunch but I needed give you guys this great tool.

>the text widget is just slow
that's probably the calculation of the metrics in the background; there's no assumption that all the lines are the same height, so metrics (the sizes of everything) get a bit expensive

>>106831493
Maybe someone should submit a TIP to the tcl core team proposing an optimisation, where you can force a text widget to have a fixed line height

>>106830966

for me it's miniz. Actually I took only the parts of miniz I needed and put them in its own file (~800 LoC).

Ooops, almost mixed the two. But I guess it's XP +1.

>>106831528
feel free, but I advise writing the damn code first so that you have a patch (or branch) to go with it
people get real sour about unimplemented suggestions, especially when they come with demands to "work on my problem for free instead of your own ones that pay the bills!"

Thanks. I never used them, but line editor was most a shell can do with pure builtins.
But in the name of transparency, I just now realized I absentmindedly left rm commands in the cleaning function... Lines 108-113 should be.
