guzzle is a Wayland screen capture CLI tool.

guzzle does not try to do any of these things:

• support X11
• capture anything other than pixels from a screen
• have a GUI

guzzle [sink] [selection] [capture]

sink can be one of:

• copy - copy the contents to the clipboard (default)
• save - save the contents to a file (default if --file is present)
• print - print the contents to stdout

The output filename for save is the current date and time, unless the --file argument is given.

The --file argument can also be given for other sink options, in which case a file will be saved in addition to the specified action.

selection can be one of:

• area - select a region
• window - select a visible window
• output - select a visible display output / monitor
• screen - all visible outputs
• anything - select a region, window, or output (default)

Selections can be saved and reused with the --area-name arguments. When an area name is first used, the user will have to make a selection. On subsequent uses, the saved area will be used automatically.

capture can be one of:

• screenshot - make a screenshot of the selected region (default)
• video - record a video of the selected region

Capture can be delayed with the --delay argument, which accepts the number of seconds to wait for your make-up crew to finish.

The duration of video recordings can be specified with the --duration argument, which accepts the number of seconds for the recording.

guzzle copy window --file=browser.png --area-name=browser

• The user is prompted to select a visible window on the screen.
• The image of the window will be copied to the clipboard and also saved to the file browser.png.
• The area currently occupied by the window will be stored and reused on later invocations with --area-name=browser.

guzzle looks for the following programs on the PATH:

• slurp (the original inspiration for this project's name)
• grim
• wl-recorder
• wl-copy

You don't have to worry about any of that if you use Nix.

guzzle talks to window manager APIs to get window and monitor regions.

The currently supported window managers are

• Sway
• Hyprland
• anything else you, the helpful reader, will contribute in PRs :-)
