Installation

mew is distributed as a CPython 3.11+ package with a small C++ extension (Google Benchmark via nanobind). On supported platforms a pre-built wheel is installed; otherwise the C++ extension is compiled from source — see Building from source for the toolchain requirements.

Using uv

With a [tool.uv.sources] entry in your pyproject.toml:

[tool.uv.sources]
mew = { git = "https://github.com/nicholasjng/mew" }

Simply run:

$ uv add mew

Using pip

$ pip install git+https://github.com/nicholasjng/mew.git

A PyPI release is planned for the future.
