PR Lens by Coldtea.ai

See code through a new lens

What it does

PR Lens is a new way to look at code. It draws animated architecture and data flow diagrams of any codebase and every pull request, so you see the change before you read a single line of code. It runs as a GitHub Action, on the CLI, or as a skill for your coding agent. Open source under MIT.

PR Lens draws what matters as animated architecture and data flow diagrams, inside the PR itself. Review the shape of the change, not a wall of diff.

A custom renderer built for humans. With zero cognitive overload See what truly matters before you read any line of code. Software is changing. The way we read it is as well Depth, weight, glyph and colour carry meaning. Not dark lines on white boxes. What is new, what was touched and what was taken out, visually linked. You see it before you read it. A pull request touches one part and moves several. The parts it did not touch stay on the page, so you build a model of the system rather than a patch See how the system moves and connect the dots faster.Animation is usually a distraction. Here it is intentional diff --git a/app/api/broadcasts/queue/route.ts b/app/api/broadcasts/queue/route.ts…from prlens.dev

  • Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
