Harp Script

• 한국어판 README_KR

• Developed: Until ~December 2018

• Status: Experimental / Discontinued

Introduction

Harp Script is a simple, experimental scripting language developed around 2018.

Features

• Limited functionality

• Simple math operations

• Console I/O

• Some built-in functions related to dxlib

Implementation Features

• Direct-to-Bytecode (No AST): Does not build an explicit Abstract Syntax Tree (AST). A recursive descent parser with an operator-precedence stack generates bytecode directly during parsing. (See express.cpp)
• Simple FFI (Foreign Function Interface): Uses WinAPI (LoadLibrary/GetProcAddress) to dynamically load .dll files (e.g., DxLib.dll). These are wrapped as built-in functions (infunc) that can be called directly from the VM. (See memory.h, infunc.cpp)
• Stack-Based VM: A simple stack-based virtual machine, written in C++, interprets and executes the bytecode. (See execute.cpp)

Usage

1. Write your code in a.harp.

2. Run harp.exe.

3. Bytecode will be generated as the output file.

4. And you can see the result. (Console or Dxlib program)

Examples & Syntax
