Library to build PHP extensions with C++

Tools and libraries to glue C/C++ APIs to high-level languages

pybind11 is a header-only C++ binding library that exposes C++ functions and classes as Python modules. It serves as a language bridge, mapping native types, inheritance hierarchies, and lambda functions into compatible Python objects to enable high-performance native code execution. The library includes specialized integration for NumPy arrays, utilizing buffer protocols to bind native C++ data without copying memory. It provides a toolkit for mapping C++ standard library data structures and smart pointers into the Python environment while maintaining cross-language memory management. The p

A tiny JavaScript runtime

Duktape is an embeddable JavaScript engine and portable scripting runtime designed for integration into C and C++ applications. It functions as a lightweight ECMAScript runtime that provides a C-JavaScript bridge for exchanging data and invoking functions between native code and a script execution environment. The engine includes an ECMAScript bytecode compiler that allows for the serialization and caching of compiled functions to disk to reduce application startup time. It organizes script dependencies using a CommonJS-compliant module loader. The runtime covers a variety of capabilities in

SWIG is a tool that generates wrapper code to expose C and C++ libraries to a wide range of higher-level programming languages. It reads annotated C/C++ header files and produces language-specific bindings from a single interface definition, supporting languages such as Python, Java, Ruby, C#, Perl, and many others. The generated wrapper code is free from the project's GPL license, allowing users to distribute it under their own terms. The tool handles modern C++ features including templates, namespaces, smart pointers, and constructs up to C++20 through specialized parsing and code generatio

Import C++ files directly from Python!

Sol2 is a C++ Lua binding library that serves as a language interoperability layer for integrating Lua scripts into C++ applications. It acts as a scripting wrapper and API toolkit, enabling the execution of Lua code and the management of shared state within a native C++ environment. The library focuses on automated function and type mapping to bridge native C++ classes and complex data types with the Lua scripting engine. It provides mechanisms for bidirectional data exchange, allowing compiled logic and variables to be synchronized between the host application and the script runtime. The s

Delphi binding for Lua 5.1 language

The following is a list of reasonably mature or actively developed open source embedded scripting languages to use in your application. Stretching the definition of a scripting language, it also includes Datalog implementations. Items with a strong copyleft license (like the GNU GPL) that will…

VerySimple.Lua - Lua 5.3 for Delphi

This is Lua contained in a single header to be bundled in C/C++ applications with ease. Lua is a powerful, efficient, lightweight, embeddable scripting language.

Cyber is a fast, efficient, and concurrent scripting language. You can embed it into your applications, games, or engines on desktop or web. Cyber also comes with a CLI so you can do scripting on your computer.

Thorium Scripting Language

JerryScript is a lightweight, ECMAScript-compliant JavaScript engine and bytecode compiler designed for resource-constrained devices. It serves as an embedded interpreter and IoT scripting runtime, enabling the execution of JavaScript code within native C applications on hardware with limited memory. The project differentiates itself through a focus on low-memory runtime management, utilizing bytecode precompilation and pre-compiled state snapshots to reduce startup time and memory overhead. It features a C-binding native bridge for bidirectional communication between native code and scripts,

A lightweight, dependency-free library for binding Lua to C++

libffi is a foreign function interface library that enables calling functions written in other languages at runtime. It serves as a multi-architecture ABI wrapper and dynamic call frame generator, allowing the execution of external functions based on runtime descriptions of argument types and return values. The project provides a portable interface to handle diverse calling conventions across different hardware architectures and operating systems. It includes capabilities for executable closure allocation, which allows foreign code to trigger callbacks within a host language via jump tables s

Luau is a high-performance programming language evolved from Lua 5.1. It consists of a bytecode virtual machine, an embeddable scripting engine, and a static code analyzer designed to provide a secure, sandboxed execution environment for host applications. The project is distinguished by its gradual typing system, which combines automatic type inference with optional manual annotations to detect bugs without requiring full static typing. It also features native vector mathematics for high-performance operations and a specialized debugging system that uses bytecode patching to minimize executi
