# Bash launcher installed as /usr/bin/fslpython: sets $FSLDIR if unset and
# execs the system python3. Upstream FSL ships this name as a private conda
# environment; on Fedora the packaged fslpy stack replaces it.

%description
FSL's wrapper scripts (eddy, xtract, bianca, fsladd, aff2rigid, ...) start
with "#!/usr/bin/env fslpython", the Python interpreter of FSL's private
conda environment. This package provides /usr/bin/fslpython for Fedora: a
launcher that exports FSLDIR (default /usr/lib/fsl) and FSLOUTPUTTYPE and
runs the system python3, and pulls in python3-fslpy and the scientific
Python stack those scripts import.

%prep
# Nothing to extract; Source0 is a single script.

%build
# Nothing to compile.

%install
install -D -p -m 0755 %{SOURCE0} %{buildroot}%{_bindir}/fslpython
# $FSLDIR/bin/fslpython, the upstream location, for scripts that call it
# by absolute path.
install -d %{buildroot}%{_prefix}/lib/fsl/bin
ln -s ../../../bin/fslpython %{buildroot}%{_prefix}/lib/fsl/bin/fslpython

%check
%{buildroot}%{_bindir}/fslpython -c 'import fsl.data.image, fsl.utils.run, numpy, nibabel'
test "$(%{buildroot}%{_bindir}/fslpython -c 'import os; print(os.environ["FSLDIR"])')" = /usr/lib/fsl

%changelog
* Sun Sep 13 2026 Morgan Hough <morgan.hough@gmail.com> - 1.0-1
- Initial package: /usr/bin/fslpython launcher over the system python3 and
  Fedora's python3-fslpy, so FSL's 16 "#!/usr/bin/env fslpython" wrapper
  scripts (eddy, xtract, bianca, fsladd, aff2rigid, pnm_stage1, film_cifti,
  possum_*.py) stop failing with "bad interpreter".
