NAME

       xdg-desktop-portal-wlr - an xdg-desktop-portal backend for wlroots

DESCRIPTION

       xdg-desktop-portal-wlr (or xdpw for short) allows applications to request screenshots and
       screencasts via xdg-desktop-portal in wlroots-based Wayland compositors.

       xdpw will try to load the configuration file from these locations:

       •   $XDG_CONFIG_HOME/xdg-desktop-portal-wlr/$XDG_CURRENT_DESKTOP
       •   $XDG_CONFIG_HOME/xdg-desktop-portal-wlr/config
       •   /etc/xdg/xdg-desktop-portal-wlr/$XDG_CURRENT_DESKTOP
       •   /etc/xdg/xdg-desktop-portal-wlr/config

       $XDG_CONFIG_HOME defaults to ~/.config. $XDG_CURRENT_DESKTOP can be a colon seperated
       list. Each element of that list will be tried.

       The configuration files use the INI file format. Example:

           [screencast]
           output_name=HDMI-A-1
           max_fps=30
           exec_before=disable_notifications.sh
           exec_after=enable_notifications.sh
           chooser_type=simple
           chooser_cmd=slurp -f %o -or

SCREENCAST OPTIONS

       These options need to be placed under the [screencast] section.

       output_name = name
           Select which output will be screencast.

           This option is used with chooser_type = none. The list of available outputs can be
           obtained via wayland-info(1) (under the zxdg_output_manager_v1 section).

       max_fps = limit
           Limit the number of frames per second to the provided rate.

           This is useful to reduce CPU usage when capturing frames at the output's refresh rate
           is unnecessary.

       exec_before = command
           Execute command before starting a screencast. The command will be executed within sh.

       exec_after = command
           Execute command after ending all screencasts. The command will be executed within sh.

       chooser_cmd = command
           Run this command to select an output.

           For more details see OUTPUT CHOOSER.

       chooser_type = type
           Specifies the input send to the chooser.

           The supported types are:
           •   default: xdpw will try to use the first chooser found in the list of hardcoded
               choosers (slurp, wofi, bemenu) and will fallback to an arbitrary output if none of
               those were found.
           •   none: xdpw will allow screencast either on the output given by output_name, or if
               empty an arbitrary output without further interaction.
           •   simple, dmenu: xdpw will launch the chooser given by chooser_cmd. For more details
               see OUTPUT CHOOSER.

   OUTPUT CHOOSER
       The chooser can be any program or script with the following behaviour:
       •   It returns any error code except 127. The error code 127 is internally used to signal
           that no command could be found and all output from it will be ignored.
       •   It returns the name of a valid output on stdout as given by wayland-info(1).
           Everything else will be handled as declined by the user.
       •   To signal that the user has declined screencast, the chooser should exit without
           anything on stdout.

       Supported types of choosers via the chooser_type option:
       •   simple: the chooser is just called without anything further on stdin.
       •   dmenu: the chooser receives a newline separated list (dmenu style) of outputs on
           stdin.
