A compact, efficient Prolog interpreter with ISO Prolog aspirations. MIT licensed Integers & Rationals are unbounded Atoms are UTF-8 of unlimited length The default double-quoted representation is *chars* list Strings & slices are super-efficient (especially with mmap'd files) REPL with history Runs on Linux, Android, FreeBSD, macOS, and WebAssembly (WASI) & Go API for calling from C (or by using WASM from Go & JS) Foreign function interface (FFI) for calling out to user code Access SQLITE databases using builtin module (uses FFI) Concurrency via tasks / linda / futures / engines (generators) Pre-emptive multi-threading Blackboarding primitives ... FFIs for GNU Scientific Library (GSL), SQLite, Raylib Delimited continuations ##EXPERIMENTAL## Rational trees ##EXPERIMENTAL## CLP(Z) ##EXPERIMENTAL##
