Look Ma – No Indexing!

on YouTube ↗42m

" summary

Shows how to make JetBrains IDE features usable while full indexes build by using DumbModeAccessType (modes like reliable-only and raw-index-acceptable), reading PSI and VirtualFile/workspace model directly, and caching per-file results with GistManager. Demonstrates turning a completion contributor into dumb aware so code completion and icon providers work during indexing, uses an inspection that finds non‑index-dependent extensions and test helpers that toggle dump mode; implemented changes restore functionality and measurably reduces user wait time.
