Magic Move for Code Snippets from first principles
Summary
A technical blog post by Rahul Ravikumar about animating code snippets using first principles. It explains why traditional presentation tools struggle with code animations, surveys diff algorithms, and argues for visual continuity over minimal edit distance. The piece describes token-based diffing with TextMate grammars and outlines how Heckel’s algorithm can identify anchors to drive smooth insertions, deletions, and movements, with references to related work on Bento and Warp.
