%description
A robust, feature-rich photo booth application built with Python, PyQt6, and OpenCV.
Uses a self-contained virtual environment to manage dependencie sand ensure
numpy compatibility. Background replacement unlikely to work.

%prep
# -n tells setup that the folder inside the tarball is named 'PyCheese-1.0'
%setup -q -n PyCheese-1.0

%build
# Nothing to compile, this is pure Python.

%install
# 1. Create Directory Structure
mkdir -p %{buildroot}/opt/%{name}
mkdir -p %{buildroot}/usr/bin
mkdir -p %{buildroot}/usr/share/applications

# 2. Copy the main script
install -m 644 pycheese.py %{buildroot}/opt/%{name}/pycheese.py

# 3. Create Virtual Environment inside the package
# Note: This requires network access during the 'rpmbuild' phase.
python3 -m venv %{buildroot}/opt/%{name}/venv

# 4. Install Dependencies
# We upgrade pip first, then install the app requirements
%{buildroot}/opt/%{name}/venv/bin/pip install --upgrade pip
%{buildroot}/opt/%{name}/venv/bin/pip install \
    --no-cache-dir \
    --ignore-installed \
    "PyQt6" \
    "opencv-python" \
    "mediapipe" \
    "numpy<2"

# 5. Fix Venv Paths (The "Relocation" Step)
# The venv currently thinks it lives in %{buildroot}/opt/...
# We must remove %{buildroot} from the scripts so they work on the target system.
find %{buildroot}/opt/%{name}/venv -type f -print0 | xargs -0 sed -i "s|%{buildroot}||g"

# 6. Create the Launcher Script
cat > %{buildroot}/usr/bin/%{name} <<EOF
#!/bin/bash
exec /opt/%{name}/venv/bin/python /opt/%{name}/pycheese.py "\$@"
EOF
chmod 755 %{buildroot}/usr/bin/%{name}

# 7. Create the Desktop Entry
cat > %{buildroot}/usr/share/applications/%{name}.desktop <<EOF
