cpp-pd-code-simplify-interface 0.1.2

Python interface for cpp-pd-code-simplify with runtime C++ compilation.

cpp-pd-code-simplify-interface

cpp-pd-code-simplify-interface is a Python package for calling the cpp-pd-code-simplify C++ implementation from Python.

The package is designed for PyPI distribution:

pip install cpp-pd-code-simplify-interface

It ships the C++ source code inside the wheel and source distribution. On first use, the package compiles a cached local dynamic library through cpp-simple-interface; later calls reuse that library through ctypes. A C++14 compiler compatible with g++ must be available at runtime.

Calls use the C++ library's default preprocessing pipeline: R1-move removal followed by nugatory-crossing removal.

Example

import cpp_pd_code_simplify_interface as simplify

pd_code = "PD[X[1,5,2,4],X[3,1,4,6],X[5,3,6,2]]"
result = simplify.simplify(pd_code)
print(result["simplification_found"])

The default max_paths=-1 uses deterministic heuristic green-path sampling in the C++ backend. Use ban_heuristic=True to request exhaustive green-path enumeration for a manageable input.

Batch use:

results = simplify.simplify_many([pd_code, "PD[]"])

To select a compiler:

CXX=clang++ python your_script.py

Windows PowerShell:

$env:CXX = "C:\path\to\g++.exe"
python your_script.py

On Windows, use a compiler whose target architecture matches Python. A 64-bit Python process needs a 64-bit compiler target.

Command-line use also supports multi-line PD-code files:

python -m cpp_pd_code_simplify_interface --pd-file inputs.pd --max-paths -1

Build And Publish
