Simple C-like scripting engine written in Free Pascal. While it is primarily designed for satania-buddy, it can also be utilized as a general-purpose, embeddable scripting engine.

It has been tested and works on the following platforms: DOS (go32v2), Windows (x86 & x64), Linux (x64), although theoretically it should work on every platforms except 8/16-bit systems.

Enable SE_LIBFFI if you need to call external functions from DLLs/SOs.

About compiler

• The compiler itself is a one-pass compiler. It follows Niklaus Wirth’s design, completely skips AST generation and generates binary directly.
• Due to the lack of AST, only constant folding and peephole optimizations are implemented.
• The virtual machine is stack-based, with super instructions to speed up certain operations.
