# JK: the above line tells my emacs editor to use rpm-spec mode

# NOTE:
# pyproj 2.4.1 does not compile yet on epel8
# because it uses exceptions inside "nogil" blocks, and this Cython
# feature was added with cython 0.29
# while el8 currently only offers Cython 0.28
# (i.e.  python3-Cython-0.28.1-3.el8.x86_64)
# see: https://cython.readthedocs.io/en/latest/src/changes.html
# so try a downgrade to 2.3.1
# upgrade requested here:
# https://bugzilla.redhat.com/show_bug.cgi?id=1770543
#
# 2.3.1 depends on shapely which is not (yet) available
# so try the older 2.2.1 version
#
# epem8 branch requested here:
# https://bugzilla.redhat.com/show_bug.cgi?id=1770541
#
# finally, this seems to work if I disable one test file for pytest....

# avoid providing the private libs:

%global _description \
Cython wrapper to provide python interfaces to Proj. \
Performs cartographic transformations between geographic (Lat/Lon) \
and map projection (x/y) coordinates. Can also transform directly \
from one map projection coordinate system to another. \
Coordinates can be given as numpy arrays, python arrays, lists or scalars. \
Optimized for numpy arrays.
