  Collection of editing commands for the CodeMirror code editor

  

  It's CodeMirror! All I had to do was write a Janet grammar for it -- very easy to do. CodeMirror is pretty amazing -- I was able to implement the "edit values with your mouse" by just asking CodeMirror for the syntax node under the cursor, checking if it parsed as a number, and if so replacing it with a different string.

  I went with CodeMirror after reading this post that compares a few different editor components: https://blog.replit.com/codemirror and I've been super happy with it.

  87 1,326 8.0 Rust

  Graph-oriented live coding language and music DSP library written in Rust

  For IDE, you can use the combo (Vite.js, Sevelte.js, and Windi CSS) I choose for building Glicol (https://glicol.org).

  I had a blog post about the combo before:

  Infrastructure for solid modeling

  

  No; Bauble doesn't know how to "rasterize" SDFs into meshes; it only knows how to raymarch them. It's theoretically possible, but it's a pretty complex problem that would take me much too long to figure out and implement. So Bauble is relegated to just making pretty pictures for now.

  Create, ray trace & export programatically defined Signed Distance Function CSG geometries with an API suited for generative art - in your browser! 🎉

  I've written a tool somewhat similar that can export meshes of sdf's created using a javascript api, check it out: https://github.com/stasilo/retrace.gl

  2 1,203 7.2 Haskell

  A math-inspired CAD program in haskell. CSG, bevels, and shells; 2D & 3D geometry; 2D gcode generation...

  

  There's also ImplicitCAD (https://github.com/Haskell-Things/ImplicitCAD) which produces STLs, as it is designed for CAD. It uses implicit functions, which I believe are similar to SDFs (I believe the idea is not to necessarily correspond to the distance function).
