Sway Mode

The Sway compatibility mode is automatically enabled if the environment variable SWAYSOCK points to a valid Sway IPC socket file. This mode provides some features such as setting the window position and getting the workspace layout. By default, the application creates an "overlay" above the currently active window, which gives the illusion that the image is opened directly inside the terminal window.

Environment

SWAYSOCK

Path to the socket file used for Sway IPC. Unset it or set it to /dev/null to  disable integration with Sway WM.

XDG_CONFIG_HOME,  XDG_CONFIG_DIRS,  HOME

Prefix of the path to the application config file, see swayimgrc(5) for details.

XDG_CACHE_HOME, HOME

Prefix for the path used as persistent storage for thumbnails.

SHELL

Shell for executing an external command and loading an image from stdout.

Signals

SIGUSR1,  SIGUSR2

Perform the actions specified in the config file.

Exit Status

The exit status is 0 if the program completed successfully and 1 if an error occurred.

Examples

View multiple files:

  swayimg photo.jpg logo.png

Start slideshow for all files (recursively) in the current directory in random order:

  swayimg --slideshow --recursive --order=random

View using pipes:

  wget -qO- https://www.kernel.org/theme/images/logos/tux.png | swayimg -

Loading stdout from external commands:

  swayimg "exec://wget -qO- https://www.kernel.org/theme/images/logos/tux.png" \
          "exec://curl -so- https://www.kernel.org/theme/images/logos/tux.png"
