cppkh-interface 0.1.0

Python interface for cppkh Khovanov homology computation with runtime C++ compilation.

cppkh-interface

cppkh-interface is a Python package for computing integer Khovanov homology with the C++ cppkh implementation.

The package is compatible with the main javakh-interface function:

import cppkh_interface

pd_code = [[1, 5, 2, 4], [3, 1, 4, 6], [5, 3, 6, 2]]
print(cppkh_interface.solve_khovanov(pd_code, de_r1=True, de_k8=True))

Unlike wrappers that ship a prebuilt DLL or shared object, this package ships the cppkh C++ source file and compiles a local executable on first use through cpp-simple-interface. The compiled executable is cached for later calls.

Install

pip install cppkh-interface

A g++ compatible compiler must be available at runtime. To select a compiler, set CXX before importing or calling the package:

CXX=clang++ python your_script.py

Windows PowerShell:

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

Build And Publish

From this directory:

poetry build
poetry publish

For local testing:

poetry run python -m cppkh_interface "[[1,5,2,4], [3,1,4,6], [5,3,6,2]]"
