PLY problem

[Ole Streicher <olebole@debian.org>]

Hi,

I have (still) problems with PLY generated files in the astropy package:
they are just not generated, and I have no idea how to generate them
correctly. For example, there are the files

astropy/coordinates/angle_lextab.py
astropy/coordinates/angle_parsetab.py

which are now cleaned up in d/clean, and they are somehow cached
regenerated from

astropy/coordinates/angle_utilities.py

The latter file contains the hint

# This module includes files automatically generated from ply (these end in
# _lextab.py and _parsetab.py). To generate these files, remove them from this
# folder, then build astropy and run the tests in-place:
#
#   python setup.py build_ext --inplace
#   pytest astropy/coordinates

but this seems not to fit very well into the pybuild procedure. And, I
have a few more of them (in astropy/units/format).

What would be the best way to regenerate them?

Best regards

Ole
