Rethinking compilers with live coding
summary
A browser-based live-coding system called The Gamma compiles an F#-like scripting language to JavaScript via Fable and avoids re-running expensive operations by building a fine-grained dependency graph caching nodes hashed from syntax and dependencies. Editing reparses the source but reuses previous nodes so only new nodes (e.g. changing blur radius) recompute; blurring previously hangs ~3s but updates that reuse cached results take ~400ms, and memory eviction is left as a pragmatic tradeoff.
