# IncludeCPP

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

```bash
pip install IncludeCPP
```

# First Steps

## Project Setup

```bash
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`:

```cpp
// 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

```bash
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

```bash
includecpp rebuild
```

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

## Use in Python

```python
from includecpp import fast_list

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

Alternative syntax:

```python
from includecpp import CppApi

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

# How to Start

## Minimal Example

```bash
# 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`:

```bash
includecpp auto math
```

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

For fastest iteration:

```bash
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

```

Sends source files to AI for analysis, suggests improvements while preserving all existing functions.

### AI Optimize

```bash
includecpp ai optimize mymodule                        # Optimize module sources
includecpp ai optimize --file src/utils.cpp            # Optimize specific files
includecpp ai optimize --agent mymodule "add SIMD"     # Custom task
```

### AI Ask

Ask questions about your project with full context awareness:

```bash
includecpp ai ask "where is collision detection?"              # Search all modules
includecpp ai ask "how does chunk generation work?" chunk_utils  # Specific module
includecpp ai ask "explain the biome system" --file include/biomes.cpp
includecpp ai ask "list all public methods" --all -x tests      # All except tests
```

Supports: module name, --file, --all, -x/--exclude

### AI Edit

Edit code with AI assistance:

```bash
includecpp ai edit "add logging to all methods" collision
includecpp ai edit "optimize the loop" --file include/utils.cpp
includecpp ai edit "add error handling" --all --think2          # Thorough mode
```

Flags:
- `--file` - specific files
- `--all` - all modules
- `-x/--exclude` - exclude modules
- `--think2` - thorough analysis (more tokens)

### AI Generate (Super Assistant)

The most powerful AI command - a full assistant with file operations and command execution.

```bash
# Basic usage
includecpp ai generate "add error handling to all functions" --file mymodule.cp

# Create new module from scratch
includecpp ai generate "fast SIMD math library" --t-new-module simd_math

# Planning mode (search, analyze, then execute)
includecpp ai generate "refactor for better performance" --t-plan --think2

# With Python file (auto-detect module usage)
includecpp ai generate "update api methods" --file mymod.cp --python main.py

# Full context mode
includecpp ai generate "comprehensive optimization" --t-max-context --think3
```

**Flags:**

### AI Tools

List available tools for the generate command:

```bash
includecpp ai tools
```

Available tools: READ_FILE, WRITE_FILE, EDIT_FILE, DELETE_FILE, CREATE_FOLDER, LIST_FOLDER, SEARCH_FILES, GREP, RUN_CMD, INCLUDECPP_CMD

### Build Error Analysis

When AI is enabled and `rebuild` fails, the build error is automatically analyzed:
- Root cause identification
- Code fix suggestions
- Prevention tips

### Configuration

```bash
includecpp ai --info          # Show status, model, usage stats
includecpp ai disable         # Disable without removing key
```

API key stored in `~/.includecpp/.secret`.

## Overloaded Methods

Specify the signature to disambiguate:

```
MODULE CLASS(Circle) {
    METHOD_CONST(intersects, const Circle&)
    METHOD_CONST(intersects, const Rect&)
}
```

## Template Instantiation

```
MODULE TEMPLATE_FUNC(maximum) TYPES(int, float, double)

MODULE STRUCT(Point) TYPES(int, float) {
    FIELD(x)
    FIELD(y)
}
```

Generates `maximum_int`, `maximum_float`, `maximum_double` and `Point_int`, `Point_float`.

## Module Dependencies

```
DEPENDS(math_utils, geometry)
```

Ensures dependent modules build first.

## VSCode IntelliSense

Generates `.pyi` stub files for autocomplete. Enable in `cpp.proj`:

```json
{
  "CPI-IntelliSense": true
}
```

## CPPY Code Conversion

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

### Python to C++

```bash
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

```bash
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

```bash
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

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

### Type Mapping

```bash
includecpp cppy types  # Show conversion tables
```

| Python | C++ |
|--------|-----|
| int | int |
| float | double |
| str | std::string |
| bool | bool |
| List[T] | std::vector<T> |
| Dict[K,V] | std::unordered_map<K,V> |
| Optional[T] | std::optional<T> |
| Tuple[...] | std::tuple<...> |

# CSSL - C-Style Scripting Language

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

## Basic Usage

```python
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:

```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

```cssl
// 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

```cssl
// 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

```cssl
// 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:

```cssl
// <== 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

```cssl
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

```python
# 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

```python
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);
''')
```
