%description
SigVisualizer is a real-time PyQt5 viewer for Lab Streaming Layer (LSL)
streams.  It discovers available outlets on the local network and plots
their signals interactively.

# Upstream has no setup.py / pyproject.toml — the files are loose Python
# modules that import each other via from sigvisualizer import ... .  We
# install them under %%{_datadir}/%%{name}/ and ship a tiny launcher in
# %%{_bindir}.

%build
# Nothing to build (pure Python).

%changelog
* Mon Jun 02 2026 Morgan Hough <morgan.hough@gmail.com> - 0-1.20260602gitaa754e6
- Initial RPM package for App-SigVisualizer (master commit aa754e6).
- Upstream has no setup.py — installs loose .py modules under
  %%{_datadir}/%%{name}/ and ships a wrapper /usr/bin/sigvisualizer that
  cd's into that dir so relative icon/ui paths resolve.
- Upstream does not declare a version; Version: 0 is intentional. Bump
  on every snapshot tag rotation.
