Babashka is a native Clojure interpreter for scripting, compiled with GraalVM native-image to produce a self-contained, fast-starting binary (`bb`). In production, it serves as a replacement for bash or Python scripting in Clojure, offering a REPL, task runner, nREPL server, HTTP client/server, process spawning, file I/O, database access via JDBC, and foreign function interface (FFI) to C libraries. The architecture is a monolith with modular feature flags: environment variables such as `BABASHKA_FEATURE_CSV` or `BABASHKA_FEATURE_JDBC` control which optional libraries (XML, YAML, CSV, Transit, http-kit, spec, logging, etc.) are compiled into the binary. The core interpreter is SCI (Small Clojure Interpreter), extended with a rich set of built-in namespaces that wrap popular Clojure libraries. Build scripts and CI pipelines automate testing on Linux, macOS, and Windows, and the project maintains an extensive library compatibility test suite with over 100 third-party Clojure libraries pinned to specific git SHAs. The codebase demonstrates exceptional craftsmanship: the JLine-based REPL with inline autosuggestion and eldoc, the FFI trampoline dispatch, the custom GraalVM features for binary size optimization, and the deftype map interface support are all non-obvious solutions to real problems in building a scripting runtime on the JVM. While primarily an application, the repository also contains a valuable data asset in `test-resources/lib_tests/bb-tested-libs.edn`, a curated registry of library compatibility that could support research on Clojure library portability.
