PYTHON 3.11 → DETERMINISTIC PORTABLE ISO C11

Start here

PyCForge is a bounded Python-to-C source transpiler with a desktop workspace, command-line interface, and structured Python API.

Source grammarPython 3.11TargetPortable ISO C11 source
Governing rule. PyCForge converts only what it can prove inside its declared static and resource-bounded contract. Unsupported input is rejected with diagnostics; it is not guessed at, partly published, or silently approximated.

Your first conversion

Save the following source as example.py:

def add(left: int, right: int) -> int:
    return left + right

In the workspace, open the file and choose Transpile Source Bundle (Ctrl+Return). From a terminal:

pycforge convert example.py --output example.c

A successful result contains a typed C prototype and definition using int64_t. Generated C is published only after the complete source bundle passes parsing, normalization, analysis, proof validation, C-IR validation, rendering, and conformance checks.

Install a downloaded source package on Windows

Use an isolated virtual environment. Substitute the actual archive location if it is not in the current PowerShell directory.

py -3.12 -m venv .venv
.\.venv\Scripts\python.exe -m pip install --upgrade pip
.\.venv\Scripts\python.exe -m pip install .\pycforge-1.0.4.tar.gz
.\.venv\Scripts\python.exe -m pycforge.ide

Verify the command surface and installed version:

.\.venv\Scripts\python.exe -c "import pycforge; print(pycforge.__version__)"
.\.venv\Scripts\pycforge.exe --help

For source review after extraction, create the environment beside the extracted directory and install the directory with python.exe -m pip install .. Keep review results separate from the original archive so its checksum remains meaningful.
