Hall's Dynamic Weight Change (DWC) model - bw Python wrapper

This is a python wrapper of the bw package's C++ implementation of the Dynamic Weight Change model from Hall et al. for adults.

Specifically, this package provides Python bindings via C++ shimming for the adult_weight and energy_build functions. See the original package for comprehensive documentation.

Installation

You can install the package via uv:

uv add git+https://github.com/nestauk/ahl_dwc.git --tag v0.1.0

Or develop locally by cloning the repo and running uv sync.

Implementation Details

• shim.hpp contains the necessary shims to replace Rcpp functionality with standard C++ and pybind11 equivalents, this is entirely new code.
• bindings.cpp contains the pybind11 bindings for the two functions we are exposing, this is entirely new code.
• adult_weight.cpp is identical to the version in the bw package.
• adult_weight.h has been modified very slightly to use shim.hpp (the main new code in src) to replace the references to math.h and Rcpp.h in the original version. The actual structure of adult_weight.h is near identical to the original though.
• energy_build.cpp is identical to the version in the bw package.
