PCCM - Python C++ Code Manager

0.4.16 verified Mon Apr 27 auth: no python

PCCM is a Python library for generating C++ code from Python class definitions, enabling seamless interoperability between Python and C++. It is currently at version 0.4.16, with moderate release cadence targeting Python >=3.6.

pip install pccm

Common errors

error ModuleNotFoundError: No module named 'pccm' ↓

cause Library not installed or installed in wrong environment.

fix

Run 'pip install pccm' in the correct Python environment.

error AttributeError: module 'pccm' has no attribute 'ClassBuilder' ↓

cause Incorrect import or older version of pccm (<0.4.0) does not have ClassBuilder.

fix

Update pccm to latest version: 'pip install --upgrade pccm' and use correct import: from pccm import ClassBuilder

error TypeError: add_public_method() missing 1 required positional argument: 'name' ↓

cause Missing method name argument.

fix

Provide method name: self.add_public_method('method_name', arg_types)

Warnings

breaking Version 0.4.x changed the API for method registration: use add_public_method instead of add_method. ↓

fix Replace add_method with add_public_method (or add_private_method for private).

gotcha ClassBuilder.build() returns a string, not a file. Users often expect it to write to disk. ↓

fix Write the returned string to a file manually if needed.

deprecated Deprecated method 'add_property' is removed in 0.4.x; use 'add_getter_setter' instead. ↓

fix Replace add_property with add_getter_setter.

Imports

ClassBuilder
wrong
```
from pccm import builder
```
correct
```
from pccm import ClassBuilder
```
The correct symbol is ClassBuilder, not a submodule.
PccmClass
wrong
```
from pccm.core import PccmClass
```
correct
```
from pccm import PccmClass
```
PccmClass is exported directly from pccm, not a nested module.

Quickstart

Define a PCCM class, add it to a builder, and generate C++ code.

from pccm import ClassBuilder, PccmClass

class MyClass(PccmClass):
    def __init__(self):
        super().__init__()
        self.add_public_method('hello', [])

builder = ClassBuilder()
builder.add_class(MyClass)
cpp_code = builder.build()
print(cpp_code)
