IncludeCPP 3.7.24

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

IncludeCPP

Write C++ code, use it in Python. Auto-generates pybind11 bindings.

pip install IncludeCPP

First Steps

Project Setup

includecpp init

Creates:

• cpp.proj - project configuration
• include/ - your C++ source files
• plugins/ - generated binding definitions

Write C++ Code

Put your code in namespace includecpp:

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

namespace includecpp {

class FastList {
public:
    void append(int val) { data.push_back(val); }
    int get(int i) { return data[i]; }
private:
    std::vector<int> data;
};

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

}  // namespace includecpp

The parser only scans code inside namespace includecpp. Everything else is ignored.

Generate Bindings

includecpp plugin fast_list include/fast_list.cpp

This runs a C++ parser that:

1. Scans your source files for classes, methods, functions
2. Extracts signatures, return types, parameter names
3. Generates plugins/fast_list.cp with binding instructions

Build

includecpp rebuild

Compiles your C++ into a Python extension module (.pyd on Windows, .so on Linux/Mac).

Use in Python

from includecpp import fast_list

my_list = fast_list.FastList()
my_list.append(42)
print(fast_list.add(1, 2))  # 3

Alternative syntax:

from includecpp import CppApi

api = CppApi()
fast_list = api.include("fast_list")

How to Start

Minimal Example

# 1. Create project
mkdir myproject && cd myproject
includecpp init

# 2. Write C++ (include/math.cpp)
cat > include/math.cpp << 'EOF'
namespace includecpp {
    int square(int x) { return x * x; }
}
EOF

# 3. Generate plugin
includecpp plugin math include/math.cpp

# 4. Build
includecpp rebuild

# 5. Use
python -c "from includecpp import math; print(math.square(7))"

Development Workflow

For active development, use auto:

includecpp auto math

This regenerates the .cp file from source and rebuilds in one command.

For fastest iteration:

includecpp rebuild --fast

Skips unchanged files. ~0.4s when nothing changed.

How IncludeCPP Works

Architecture

Your C++ Source            Plugin File (.cp)           Python Module
include/math.cpp    --->   plugins/math.cp     --->    math.cpXXX.pyd
     ^                           ^                          ^
     |                           |                          |
  C++ parser              Binding config             pybind11 compiled
  extracts API            (editable)                 extension

The Parser

The C++ parser (parser.cpp) runs as a compiled executable. It:

1. Tokenizes your C++ source files
2. Identifies the namespace includecpp block
3. Extracts:
   • Class names and inheritance
   • Method signatures (name, return type, parameters)
   • Function signatures
   • Template instantiations
   • Const/static qualifiers
4. Outputs structured binding instructions to .cp files

Plugin Files (.cp)

The .cp format is a declarative binding specification:

SOURCE(math.cpp) math

PUBLIC(
    math CLASS(Calculator) {
        CONSTRUCTOR()
        CONSTRUCTOR(int)
        METHOD(add)
        METHOD_CONST(getValue)
        FIELD(value)
    }

    math FUNC(square)
    math TEMPLATE_FUNC(maximum) TYPES(int, float, double)
)

Key directives:

• SOURCE(file.cpp) module_name - links source to module
• PUBLIC(...) - defines public bindings
• CLASS(Name) - expose a class
• STRUCT(Name) - expose a struct
• FUNC(name) - expose a free function
• METHOD(name) - expose a class method
• METHOD_CONST(name, signature) - for overloaded methods
• TEMPLATE_FUNC(name) TYPES(...) - instantiate template
• CONSTRUCTOR(args) - expose constructor
• FIELD(name) - expose member variable
• DEPENDS(mod1, mod2) - declare module dependencies

Build System

The build manager:

1. Reads cpp.proj configuration
2. Parses all .cp files in plugins/
3. Generates pybind11 binding code
4. Compiles using CMake with detected compiler (MSVC, GCC, Clang)
5. Places output in ~/.includecpp/builds/ (not in your project)
6. Creates a registry so Python can find modules

Caching layers:

• Object files: Only recompile changed .cpp files
• Generator cache: Compiler/CMake detection runs once
• SHA256 hashes: Skip unchanged modules entirely

CPPY Code Conversion

Convert code between Python and C++ with full support for classes, functions, and type hints.

Python to C++

includecpp cppy convert math_utils.py --cpp
includecpp cppy convert data.py --cpp --no-h  # Skip header
includecpp cppy convert src/*.py --cpp -o include/

Converts Python code to optimized C++ with:

• Type hints mapped to C++ types (int, str -> std::string, List -> std::vector)
• Classes with constructors, methods, fields
• Functions with proper signatures
• List comprehensions to STL algorithms
• Exception handling to try/catch

C++ to Python

includecpp cppy convert utils.cpp --py
includecpp cppy convert mymodule.cp --py  # Auto-resolve SOURCE()

Converts C++ to Python with:

• STL types mapped to Python equivalents
• Classes with type hints
• Methods become class methods with self
• Structs become dataclasses

AI-Assisted Conversion

includecpp cppy convert complex_lib.py --cpp --ai
includecpp cppy convert advanced.cpp --py --ai -v

The --ai flag enables intelligent conversion with:

• Section-by-section analysis and processing
• Automatic --think2 context level
• Comprehensive rulebase for precise conversions
• pybind11 wrappers for Python features without C++ equivalents:
  • Generators -> callback pattern / py::iterator
  • Async/await -> std::async / std::future
  • Context managers -> RAII pattern
  • Duck typing -> templates with concepts
• Reports API changes to user
• Fallback to standard conversion if AI unavailable

Workaround Examples:

Python Feature	C++ Workaround
yield	Callback pattern or py::iterator
async/await	std::async + std::future
with context	RAII ScopedResource class
List comprehension	transform_to_vector template
Dict comprehension	transform_to_map template
Dynamic attributes	py::object

Analyze Code

includecpp cppy analyze math.py           # View structure
includecpp cppy analyze utils.cpp --json  # JSON output

Type Mapping

includecpp cppy types  # Show conversion tables

Python	C++

CSSL - C-Style Scripting Language

IncludeCPP includes CSSL, a scripting language with advanced data manipulation features.

Basic Usage

from includecpp import CSSL

# Execute CSSL code
CSSL.exec('''
    printl("Hello from CSSL!");

    int x = 10;
    for (i in range(0, 5)) {
        x = x + i;
    }
    printl(x);
''')

# Execute with arguments
result = CSSL.exec('''
    int a = parameter.get(0);
    int b = parameter.get(1);
    parameter.return(a + b);
''', 5, 3)
print(result)  # 8

Live Object Sharing

Share Python objects with CSSL scripts. Changes in CSSL reflect back to Python:

from includecpp import CSSL

class Counter:
    def __init__(self):
        self.value = 100

counter = Counter()
cssl = CSSL.CsslLang()
cssl.share(counter, "cnt")

# Modify in CSSL - changes reflect in Python!
cssl.exec('''
    $cnt.value = $cnt.value - 10;
    printl($cnt.value);  // 90
''')

print(counter.value)  # 90 - Changed!

Shared Object Syntax

• $name - Access shared object
• $name.property - Access/modify properties
• $name.method() - Call methods
• delete("name") - Remove shared object

Data Types

// Basic types
int x = 42;
float pi = 3.14;
string name = "CSSL";
bool active = true;

// Collections
array<int> arr;
arr.push(1);
arr.push(2);
printl(arr.length());  // 2

vector<string> vec;
vec.push("A");
vec.push("B");

stack<int> s;
s.push(10);
s.pop();

Control Flow

// If/elif/else
if (x > 10) {
    printl("big");
} elif (x > 5) {
    printl("medium");
} else {
    printl("small");
}

// For loops
for (i in range(0, 10)) {
    printl(i);
}

for (i in range(0, 10, 2)) {  // with step
    printl(i);  // 0, 2, 4, 6, 8
}

// Foreach
array<string> items;
items.push("A");
items.push("B");
foreach (item in items) {
    printl(item);
}

// While
int count = 0;
while (count < 5) {
    printl(count);
    count = count + 1;
}

Functions

// Basic function
void greet(string name) {
    printl("Hello, " + name + "!");
}

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

// Global variables
global version = "1.0.0";
printl(@version);

// r@ syntax for global declaration
r@myGlobal = "value";
printl(@myGlobal);

BruteForce Injection System

CSSL's unique injection operators for data manipulation:

// <== Move data (replaces target)
target <== source;

// +<== Copy & add to target
target +<== source;

// -<== Move & remove from source
target -<== source;

// <<== Code infusion into functions
myFunc() <<== {
    printl("Injected code!");
};

// +<<== Add code without replacing
myFunc() +<<== {
    printl("Additional code!");
};

String Methods

string s = "Hello World";

// Methods
s.length();           // 11
s.toUpper();          // "HELLO WORLD"
s.toLower();          // "hello world"
s.contains("World");  // true
s.startsWith("Hello"); // true
s.endsWith("World");  // true
s.replace("World", "CSSL");
s.split(" ");         // ["Hello", "World"]
s.trim();             // Remove whitespace
s.substring(0, 5);    // "Hello"

CSSL Modules

# Create callable module
module = CSSL.module('''
    string name = parameter.get(0);
    printl("Hello, " + name + "!");
''')
module("World")  # Prints: Hello, World!

# Create module with functions
math_mod = CSSL.makemodule('''
    int add(int a, int b) {
        return a + b;
    }

    int multiply(int a, int b) {
        return a * b;
    }
''')
print(math_mod.add(2, 3))       # 5
print(math_mod.multiply(4, 5))  # 20

Inline Payloads

cssl = CSSL.CsslLang()

# Register code as payload
cssl.code("helpers", '''
    global version = "1.0.0";
    void log(string msg) {
        printl("[LOG] " + msg);
    }
''')

# Use in CSSL
cssl.exec('''
    payload("helpers");
    @log("Application started");
    printl(@version);
''')

  • Generator expressions: (x for x in items) now converts to vector
  • Tuple unpacking: a, b = func() now uses C++17 structured bindings
• AI Conversion Flags:
  • New --think flag for less context mode
  • New --think3 flag for maximum context mode
  • New --websearch flag for web search in AI conversion
  • Default: --think2 mode (unchanged behavior)

v3.3.10

• CPPY Converter seeded RNG fixes:
  • Fixed rng = random.Random(seed) then rng.randint() - now properly tracks seeded RNG variables
  • Fixed random.choices(...)[0] subscript - returns single element directly without [0]
  • Seeded RNG methods (randint, uniform, choice, random) now use the tracked variable with proper C++ distributions

v3.3.9

• CPPY Converter fixes:
  • Added f-string (JoinedStr) support - f"text {expr}" now converts to string concatenation
  • Fixed random.Random(seed).method() chained calls - now generates proper inline lambda with seeded RNG
  • Fixed random.choices(items, weights=weights) keyword argument handling
  • Improved string type detection in f-string expressions

v3.3.8

• Major rulebased converter improvements:
  • Added Python random module support (randint, uniform, choice, sample, shuffle, gauss, etc.)
  • Added os module support (getcwd, path.join, path.exists, listdir, mkdir, etc.)
  • Added time module support (sleep, time, perf_counter, monotonic)
  • Added sys module support (exit, platform)
  • Added math module support (sqrt, pow, sin, cos, log, etc.)
  • Added re (regex) module support (match, search, sub, findall)
  • Added threading module support (Thread, Lock, Semaphore, etc.)
  • Added collections module support (deque, defaultdict, Counter)
  • Added pathlib.Path support
• Unconvertible code detection:
  • Automatically detects GUI frameworks (tkinter, PyQt, PySide, pygame) and other unconvertible modules
  • Shows red warning with line numbers when unconvertible code is found
  • New --force flag to convert anyway (with /* UNCONVERTIBLE */ comments)
  • Supports 30+ modules in detection (numpy, pandas, flask, django, etc.)
• Fixed duplicate file output in cppy convert --ai
• Plugin command now skips inline and underscore-prefixed functions
