PineAPFEL is a C++ library and CLI tool for creating and evolving PineAPPL interpolation grids using APFEL++. It can fill grids with analytically computed coefficient functions for unpolarized and longitudinally polarized DIS, SIA, and SIDIS structure functions, and evolve them into FK tables via DGLAP evolution.

All physics parameters (coupling constants, thresholds, perturbative order, etc.) are specified through YAML configuration files through a theory card, an operator card, and optionally a grid card rather than being hardcoded.
