# anvil-python-numpy -- numpy for the printer's CPython, into its
# site-packages.
#
# THIS IS NOT AN OPTIONAL SCIENTIFIC EXTRA. It is the package klippy cannot
# start without. extras/stepper_resonance_tester.py opens with a bare
# `import numpy as np`; klippy.py:122 walks EVERY config section through a
# load_object that does not catch ImportError; and printer.base.cfg includes
# FlashForge's printer.vibration.cfg, which declares [stepper_resonance_tester].
# So on a numpy-less install klippy never reaches ready -- it does not merely
# lose a feature. anvil-klipper names this package in its Depends for that
# reason. docs/notes/44-vfa-calibration.md has the whole chain.
#
# WHAT IT BUYS BACK, beyond the boot: the VFA (motor torque-ripple) calibration
# behind STEPPER_RESONANCE_FACTORY_CALIBRATE, and SHAPER_CALIBRATE /
# TEST_RESONANCES, which have been dead for exactly the same reason since
# klippy moved to our own CPython 3.13.
PKG_NAME=anvil-python-numpy

# ARCHITECTURE IS THE DEFAULT, mipsel_xburst2, and it is not a formality here
# any more than it is for anvil-klipper: this package is mostly compiled code.
# An `all` would let it install on a machine whose kernel refuses every .so in
# it, and the failure would arrive as an ImportError halfway through a boot.

# python ALONE, and no BLAS: -Dallow-noblas=true below picks numpy's bundled
# lapack_lite instead. That is not a corner cut for size -- there is no BLAS in
# this feed to link against, and lapack_lite is enough for the one linalg call
# the calibration makes (np.linalg.lstsq, in _r2_sinusoidal_fit).

PKG_DESCRIPTION="numpy for klippy -- the FFT, least-squares and polynomial fitting that extras/stepper_resonance_tester.py and shaper_calibrate.py are written against. Built with meson-python against a cross file, without BLAS."
