Pest: Building a Language Server
summary
Parser built with Pest (PEG grammar) with heavy TDD coverage, JSON/RPC handled by Parity’s implementation over stdio, and a WebAssembly browser parser demo proves cross‑platform deployment. Grammar sizes reach thousands of lines (2.5k–10k) and parse in under a second; throughput around 200 MB/s on JSON benchmarks. Pest lacks a native concurrent parser so parsing is guarded with Arc+Mutex. Current status: beta with an expected 10k user base.
