# Flatpak manifest for ViewFree.
#
# Built against the GNOME runtime purely for its libraries — ViewFree does not
# use libadwaita and does not assume GNOME conventions, because it has to look
# right on KDE, Xfce, Cinnamon, MATE and LXQt too.
#
# Build locally with:
#   flatpak run org.flatpak.Builder --user --install --force-clean \
#       build packaging/flatpak/io.github.justlinuxnoob.ViewFree.yml
#
# `cargo-sources.json` is generated by packaging/flatpak/generate-sources.sh and
# lets the build run with no network access, which Flathub requires.

  # Both display servers. ViewFree makes no X11-only assumptions, but falls

  # An image viewer is pointed at arbitrary files on the disk, so it needs to
  # be able to read them — and the batch tools need to write results back
  # beside them. There is no narrower permission that lets someone convert a
  # folder of photographs in place.
  - --filesystem=host

  # Reading and writing the *host's* mimeapps.list is what makes the one-click
  # "become the default image viewer" work, and what makes undoing it work.

  # Opening the containing folder in the user's file manager.

  # Explicitly NOT requested: --share=network. ViewFree has no telemetry, no
  # update check and no account system, so it has no reason to reach the
  # network, and saying so here makes that promise enforceable rather than
  # merely stated in a README.

    # Scoped to this module rather than declared at the top level: a
    # top-level `append-path` also applies to the finish stage, where it
    # displaces /app/bin from PATH and makes flatpak-builder report
    # "Command 'viewfree' not found" even though the binary is right there.
