    MinForth

    MinForth

    A minimalistic but complete standard Forth compiler in C

    MinForth V3.4 is a classic Forth system with command-line interface. Development resource requirements are minimal. A source text editor and a C compiler are sufficient. By design no toolchain is required to adapt or rebuild MinForth. A complete rebuild takes only few seconds. Current sources are for Windows and Linux (32-bit or 64-bit). MinForth primitive definitions are written in mixed Forth and C language and are transpiled to pure C code. Main but not exclusive application for the transpiler is to build the MinForth V3.4 high-level Forth compiler. MinForth V3.4 is widely conformant to the Forth-2012 draft standard and passes the usual test suites. Feedback and bug reports are welcome per - Usenet forum https://groups.google.com/forum/#!forum/comp.lang.forth - email to minforth@gmx.net

    RustPython

    RustPython

    A Python Interpreter written in Rust

    RustPython is an implementation of the Python programming language written in Rust. Its goal is to provide a fast, embeddable, and secure interpreter that can be integrated into Rust applications or used standalone. Because it’s in Rust, it benefits from memory safety and modern tooling, allowing developers to compile Python into efficient binaries or embed it as a scripting engine in Rust projects. The interpreter aims to support the Python standard library, dynamic typing, garbage collection, and common builtins, although full compatibility is a work in progress. It also supports bytecode compilation and execution, enabling faster startup and reuse of parsed code. By bridging the two language ecosystems, RustPython offers a compelling path for projects that want Python flexibility but desire Rust’s performance and safety discipline.

    BAScript

    Scripting engine for Pascal compilers.

    BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Delphi, Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. The virtual machine defines its own language, called the BAScript language. It is a low-level language, somewhat similar to the Assembler language, which is not intended to be easy to program but easy to execute. So it is recommendable to use other higher level languages and translate them into BAScript language. Package includes two compilers that translates from a higher-level language to the BAScript language. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript.
