%global desc %{expand: \
TRX is a community-driven binary file format for storing tractography
streamlines (computed from diffusion MRI). The python-trx-python
package provides the reference reader/writer plus a `trx` CLI for
manipulating .trx files (concatenation, conversion, validation).

Required by dipy 1.12+ for its tractogram I/O. Upstream:

# Upstream uses setuptools_scm for version detection. The release tarball
# has no .git/ tree, so setuptools_scm falls back to "0.0", which trips
# Fedora's _python_dist_allow_version_zero check. Set
# SETUPTOOLS_SCM_PRETEND_VERSION via the global env so ALL build phases
# (generate_buildrequires, build, install) see it consistently —
# generate_buildrequires also runs the wheel-metadata step and was the
# step that failed on -1.

%changelog
* Mon May 25 2026 Morgan Hough <morgan.hough@gmail.com> - 0.4.0-2
- Set SETUPTOOLS_SCM_PRETEND_VERSION in %%generate_buildrequires too —
  -1 only set it for %%build and %%install but the wheel-metadata
  extraction in %%pyproject_buildrequires also needs it. Without it,
  setuptools_scm fell back to "0.0" and Fedora's version-zero check
  refused to ship the wheel.

* Mon May 25 2026 Morgan Hough <morgan.hough@gmail.com> - 0.4.0-1
- Initial COPR build (mhough/neurofedora). Prerequisite for python-dipy
  1.12+ which added a hard dep on trx-python for tractogram I/O. Pure
  Python, setuptools build backend, BSD-3-Clause. All runtime deps
  (deepdiff, nibabel, numpy, typer) already in Fedora.
