hi everyone.

im a big fan of D since uh, i guess it was around 2014 but i 
never had the time to dig really deep into it. ~4 weeks ago i 
started to write my game engine (not the first time haha) but in 
D, and im so extremely amazed how frictionless this whole process 
was so far. I dont understand why this language hasnt more 
widespread adoption, its awesome <3

greetings!

ps.: 400 unit tests so far, i love this!

So you probably saw my thread about text-editor from scratch. I 
use Raylib for my editor's rendering, but I was also thinking of 
maybe making it easier to later swap backends and also allow 
software rendering, like GOP for example.

What's your experience with software rendering, how do you draw 
pixels on screen? Because I initially considered specifically 
that, but on Linux/BSD/X11 it was extremely difficult, for some 
reason, to just open a window  and draw one pixel - I eventually 
managed to do it, but it was a lot of boilerplate, whereas with 
Raylib "it just werks" (tm) and is pretty portable.

I also do wonder why haven't you used Raylib yourself (D has a 
nice binding!).

I wanted to write everything from scratch and use as little third 
party code as possible. so I wrote my own UI system which i 
simply call "widget". and writing the software renderer for it 
was really fun and a huge learning experience. aside from 
rasterizing and only updating the pixels which actually changed, 
multit hreading the drawing loop gave the biggest performance 
boost and D made that super simple to implement

Since there is no source linked, in this is Software Rendering, 
you draw every pixel on a buffer (RAM) and then send/swap with 
the video buffer? So you are using only CPU?

hi, yes both the UI and the raymarcher write to a byte[] which i 
just hand over to the OS.

it totally is! the only issue i have is with vscode + code-d. its 
less usable than im used to from other IDEs/languages. do you 
have a suggestions for me on how i could improve that situation 
or is that just something i have to deal with (the D tax :P ) im 
using github copilot for autocomplete and refactoring help, so it 
hides some of the shortcomings.

I only code with syntax highlighting :)
Sometimes I also use grep to find things.

i remember the times without syntax highlighting :P but im glad 
about modern IDE features, im getting old remembering all the
