Exploring Scala Tooling ecosystem

" summary

Compares concrete tooling: Metals: LSP client with type‑at‑point, worksheet and IDE integrations, Bloop 1.3: keeps a single hot compiler, deduplicates compilations and offers isolation for concurrent builds — claims up to 20x faster builds, and build choices like SBT 1.3 (faster, Coursier parallel downloads, simple semantics=true compiler plugin config), Mill, Pants and Bazel. Explains SemanticDB as a portable schema (JSON/protobuf) for fast cross‑tool analysis and shows which toolchains actually integrate via LSP/BSP.
