# xdg-desktop-portal:
|
|
# - dbus user service which allows sandboxed applications to request specific things from their external environment.
|
|
# - frequently paired with portal implementations like `xdg-desktop-portal-gtk`, `xdg-desktop-portal-wlr`
|
|
# wherein `xdg-desktop-portal` is the only component which speaks to the outside world, and the implementations speak only to the xdg-desktop-portal.
|
|
# - org.freedesktop.portal.OpenURI:
|
|
# - <https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.OpenURI.html>
|
|
# - request that the OS open some URI for the user
|
|
# - optionally provide a list of recommended .desktop files to handle the URI
|
|
# - xdg-desktop-portal dispatches this request to the backend (xdg-desktop-portal-gtk) which will present an app chooser to the user by default
|
|
# - xdg-desktop-portal then executes the chosen .desktop file, passing it the URI.
|
|
# - example (glib): `gdbus call --session --timeout 10 --dest org.freedesktop.portal.Desktop --object-path /org/freedesktop/portal/desktop --method org.freedesktop.portal.OpenURI.OpenURI '' 'https://www.google.com' "{'ask': <false>}"`
|
|
# - force non-flatpak glib apps to use this portal with: GTK_USE_PORTAL=1 or GIO_USE_PORTALS=1 (and then making sure the app can't see mimeapps.list)
|
|
# - org.freedesktop.portal.DynamicLauncher
|
|
# - <https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.DynamicLauncher.html>
|
|
# - whereas OpenURI requires a URI argument, DynamicLauncher is just "launch an app by <app_id>.desktop"
|
|
# - example (glib): `gdbus call --session --timeout 10 --dest org.freedesktop.portal.Desktop --object-path /org/freedesktop/portal/desktop --method org.freedesktop.portal.DynamicLauncher.Launch 'audacity.desktop' "{}"`
|
|
# - .desktop files are searched for in ~/.local/share/xdg-desktop-portal/applications
|
|
#
|
|
# debugging:
|
|
# - show available portals: <https://codeberg.org/tytan652/door-knocker>
