# Flatpak manifest for the single-file bundle attached to every GitHub release
# (pdfcraft-<version>-linux-<arch>.flatpak). Build it with packaging/linux/flatpak-bundle.sh.
#
# It repackages the release's own Linux tarball (pdfcraft-<version>-linux-<arch>.tar.gz, built on
# Ubuntu 22.04 by package.sh) instead of compiling Rust inside flatpak-builder: no network and no
# vendored crate sources during the build, a few seconds instead of 20+ minutes, and byte-for-byte
# the same binaries as the AppImage/deb/rpm. The script unpacks the tarball into `stage/` next to a
# copy of this file. The binaries need glibc >= 2.35 and load X11, Wayland, xkbcommon and Vulkan
# at runtime; the freedesktop runtime has all of them, and the GPU driver comes from its
# org.freedesktop.Platform.GL extension.
#
# ai.storyteller.pdfcraft.yml (same directory) is the from-source manifest for Flathub. Keep
# runtime-version and finish-args identical in both (packaging-lint checks this).

  # Display: Wayland first; X11 only when no Wayland compositor is running.

  - --device=dri
  # Printing: lpstat/lp (the cups-client module) reach the host's CUPS through its socket and
  # find driverless network printers through Avahi (`lpstat -e`). Without these the Print
  # dialog lists no printers.
  - --socket=cups
  - --system-talk-name=org.freedesktop.Avahi
  # The user's CUPS settings, read-only: their default printer and saved options (lpoptions)
  # and a print server named in their client.conf, which lp reaches over the network.
  - --filesystem=~/.cups:ro
  # Open/Save dialogs go through the file-chooser portal (rfd's xdg-portal backend) and
  # drag-and-drop through the document portal, so picked files work anywhere without broad
  # filesystem access. Documents and Downloads, where PDFs usually live, are granted so files
  # passed by path (the command line, Open Recent, "Save" next to the original) work there.
  - --filesystem=xdg-documents
  - --filesystem=xdg-download
  # Network: Help ▸ Check for updates reaches GitHub. The optional --control channel still listens
  # on 127.0.0.1 inside the sandbox.
  - --share=network
  # Deliberately not granted: home/host filesystem access. No CUPS socket either: printing
  # runs the `lp` command (crates/print), which the freedesktop runtime doesn't ship, so Print
  # reports that the spooler is unavailable until it goes through the print portal.
modules:
  # CUPS client tools for craft-print: the runtime has libcups but not lpstat/lp/lpoptions.
  # Linked statically against this release's libcups, so a runtime update can't break them;
  # the socket path matches the host's, which --socket=cups mounts.
