Transpile anything to everything!
summary
Compass adds a web‑friendly JavaScript transpiler that translates MongoDB queries and aggregations from any language to any language by combining ANTLR grammars (for parsing) with generated visitors, a shared code‑generation superclass, and a symbol table driven by YAML templates. Contributors add a language by supplying templates (for outputs) or a small visitor (for inputs), keeping development linear instead of quadratic. The system is pluggable, runs inside the Electron app, and already produces readable client snippets for Compass/Atlas.
