Simple build

I'm using Python 3.11 for this project

python3.11 -m venv venv
source venv/bin/activate.fish
python3.11 -m pip install -r requirements.txt

Building on Fedora

To build in a toolbox on Fedora Silverblue:

toolbox create photo-viewer
toolbox enter photo-viewer
sudo dnf install -y \
    python3.11 \
    python3.11-devel \
    gcc \
    patchelf \
    mesa-libGL \
    mesa-libEGL \
    libatomic \
    freetype \
    libxkbcommon \
    libxkbcommon-x11 \
    dbus-libs \
    fontconfig \
    xcb-util-cursor \
    xcb-util-wm \
    xcb-util-keysyms \
    gdk-pixbuf2 \
    atk \
    gtk3
python3.11 -m ensurepip --upgrade
./build.sh

Then, I:

1. Moved the binary to ~/.local/bin to put it on my path

2. Added the following ~/.local/share/applications/PhotoViewer.desktop file to make it available via wofi/dmenu:

[Desktop Entry]
Name=PhotoViewer
Comment=Open images with PhotoViewer
Exec=/home/nicaudinet/.local/bin/main.linux %F
Icon=/home/nicaudinet/.local/share/icons/photo-viewer.png
Terminal=false
Type=Application
Categories=Graphics;Viewer;
StartupNotify=true
MimeType=image/png;image/jpeg;image/jpg;image/gif;image/bmp;

3. Added the camera.png icon to home/nicaudinet/.local/share/icons/photo-viewer.png

4. Refreshed the XDG mimetype database to make PhotoViewer the default app with which to open PNG or JPEG files
