IncludeCPP 4.7.0

Professional C++ Python bindings with type-generic templates, pystubs and native threading

IncludeCPP

Use C++ code in Python. Write your C++ functions and classes, IncludeCPP generates the Python bindings automatically.

pip install IncludeCPP

Quick Start

1. Create a Project

mkdir myproject && cd myproject
includecpp init

This creates:

• cpp.proj - your project settings
• include/ - put your C++ files here
• plugins/ - binding files go here (auto-generated)

2. Write Some C++

Create include/math.cpp:

namespace includecpp {

int add(int a, int b) {
    return a + b;
}

int multiply(int a, int b) {
    return a * b;
}

}

Your code must be inside namespace includecpp. Everything outside is ignored.

3. Generate Bindings

includecpp plugin math include/math.cpp

This scans your C++ and creates plugins/math.cp with the binding instructions.

4. Build

includecpp rebuild

Compiles your C++ into a Python module.

5. Use in Python

from includecpp import math

print(math.add(2, 3))       # 5
print(math.multiply(4, 5))  # 20

Done. Your C++ code works in Python.

---

Classes

C++ classes work the same way:

// include/calculator.cpp
#include <vector>

namespace includecpp {

class Calculator {
public:
    Calculator() : result(0) {}

    void add(int x) { result += x; }
    void subtract(int x) { result -= x; }
    int getResult() { return result; }
    void reset() { result = 0; }

private:
    int result;
};

}

Generate and build:

includecpp plugin calculator include/calculator.cpp
includecpp rebuild

Use in Python:

from includecpp import calculator

calc = calculator.Calculator()
calc.add(10)
calc.add(5)
calc.subtract(3)
print(calc.getResult())  # 12

Development Workflow

When you're actively working on your C++:

# Regenerate bindings AND rebuild in one command
includecpp auto math

# Fast rebuild (skips unchanged files, ~0.4s when nothing changed)
includecpp rebuild --fast

# Rebuild everything from scratch
includecpp rebuild --clean

---

CLI Commands

Command	What it does
init	Create project structure
plugin <name> <file.cpp>	Generate bindings from C++
auto <name>	Regenerate bindings + rebuild
rebuild	Compile all modules
rebuild --fast	Fast incremental build
rebuild --clean	Full clean rebuild
get <name>	Show module's API
server start	Start HomeServer
server stop	Stop HomeServer
server upload	Upload file/project
server download	Download file/project
server list	List stored items

---

Project Configuration

The cpp.proj file controls your build:

{
  "project": "MyProject",
  "include": "/include",
  "plugins": "/plugins",
  "compiler": {
    "standard": "c++17",
    "optimization": "O3"
  }
}

---

Plugin Files (.cp)

The .cp files tell IncludeCPP what to expose. They're auto-generated, but you can edit them:

SOURCE(calculator.cpp) calculator

PUBLIC(
    calculator CLASS(Calculator) {
        CONSTRUCTOR()
        METHOD(add)
        METHOD(subtract)
        METHOD(getResult)
        METHOD(reset)
    }
)

Common directives:

• CLASS(Name) - expose a class
• METHOD(name) - expose a method
• FUNC(name) - expose a function
• FIELD(name) - expose a member variable
• CONSTRUCTOR() or CONSTRUCTOR(int, string) - expose constructor

---

Requirements

• Python 3.9+
• C++ compiler (g++, clang++, or MSVC)
• CMake

pybind11 is installed automatically.

HomeServer

Store and manage your modules, projects and files locally with the HomeServer:

# Install and start the server (one-time setup)
includecpp server install

# Manual start/stop
includecpp server start
includecpp server stop
includecpp server status

# Upload files or projects
includecpp server upload mymodule ./include/mymodule.cpp
includecpp server upload myproject ./myproject --project

# List, download, delete
includecpp server list
includecpp server download mymodule ./backup/
includecpp server delete mymodule

# Change port (default: 2007)
includecpp server port 3000

# Remove HomeServer completely
includecpp server deinstall

The server runs silently in the background and can auto-start with Windows.

Experimental Features

IncludeCPP also includes experimental features that are still in development:

• CSSL - A scripting language for runtime code manipulation
• AI Commands - OpenAI-powered code analysis (includecpp ai)
• CPPY - Python to C++ conversion (includecpp cppy)

These are hidden by default. To enable them:

includecpp settings

Check "Enable Experimental Features" and save.

Warning: Experimental features may have bugs or breaking changes between versions.
