Trealla Prolog: Compact and efficient Prolog interpreter

Trealla Prolog is a compact and efficient Prolog interpreter written in C, aiming for ISO Prolog compliance. It supports unbounded integers and rationals, UTF-8 atoms of unlimited length, and efficient strings and slices. The interpreter includes a REPL with history and runs on various platforms like Linux, Android, and WebAssembly. It offers an API for C integration, a foreign function interface for calling C code, and supports SQLite database access. Additionally, it provides concurrency features like tasks, linda, and engines, along with pre-emptive multi-threading and blackboarding primitives. Trealla also supports experimental features like delimited continuations and rational trees. The project is open source under the MIT license and can be accessed from trealla-prolog.org. The interpreter uses UTF-8 internally and seamlessly handles code-point specific requirements. Building Trealla involves cloning the repository, installing necessary dependencies, and compiling the source code. Contributions to the project are welcome, and the project acknowledges the contributions of various individuals.
