Pretty Code

I am of the opinion that AI coding tools enable us to build personalised tools for ourselves.

In my Python newsletter, I use quite a lot of code examples, and Substack famously does not include syntax highlighting natively. So code looks pretty uninspiring for those of us who live in the IDE.

Initially I used Carbon.sh, which did the job, but I wanted more features:

  • Generate gradients and other patterns for backgrounds
  • Use uploaded images as backgrounds
  • Customizable syntax highlighting, supporting more languages
  • Render code diffs
  • Customizable fonts

I built this using v0 for the initial design (heavily inspired by carbon.sh). Then Cursor to polish if off.

Take it for a spin!
