D. Williams-Young's reuseable density functional theory (DFT) grid library
copied from cf-post-staging / integratorxxIntegratorXX is a modern C++ library for the generation of atomic and molecular grids for quantum chemistry calculations. Among the most important applications of these grids is the evaluation of exchange--correlation (XC) related quantities (energies, potentials, etc) required for density functional theory calculations. IntegratorXX provides a uniform interface for the generation of primitive, radial and solid angle quadratures, as well as their combination into spherical grids.
