NAME

slurp - select a region in a Wayland compositor

SYNOPSIS

slurp [options...]

DESCRIPTION

slurp is a command-line utility to select a region from Wayland compositors which support the layer-shell protocol. It lets the user hold the pointer to select, or click to cancel the selection.

If the standard input is not a TTY or the -r option is used, slurp will read a list of predefined rectangles for quick selection. Each line must be in the form "<x>,<y> <width>x<height> [label]". The label is optional and can be any string that doesn't contain newlines. It can be accessed using the "%l" sequence in a format string.

If the Esc key is pressed, selection is cancelled. If the Space key is held, the selection is moved instead of being resized.

OPTIONS

-h

Show help message and quit.

-d

Display dimensions of selection.

-b color

Set background color. See COLORS for more detail.

-c color

Set border color. See COLORS for more detail.

-s color

Set selection color. See COLORS for more detail.

-B color

Set color for highlighting predefined rectangles from standard input when not selected.

-F font family

Set the font family name when displaying the dimensions box. Only useful when combined with the -d option. The available font family names guaranteed to work are the standard generic CSS2 options: serif, sans-serif, monospace, cursive and fantasy. It defaults to the sans-serif family name.

-w weight

Set border weight.

-f format

Set format. See FORMAT for more detail.

-p

Select a single pixel instead of a rectangle. This mode ignores any predefined rectangles read from the standard input.

-o

Add predefined rectangles for all outputs, as if provided on standard input. The label will be the name of the output.

-r

Require the user to select one of the predefined rectangles. These can come from standard input, if -o is used, the rectangles of all display outputs. This option conflicts with -p.

-a width:height

Force selections to have the given aspect ratio. This constraint is not applied to the predefined rectangles specified using -o.

COLORS

Colors may be specified in #RRGGBB or #RRGGBBAA format. The # is optional.

FORMAT

Interpreted sequences are:

%x The x-coordinate of the selection

%y The y-coordinate of the selection

%w The width of the selection

%h The height of the selection

%X The x-coordinate of the selection with coordinates relative to the output

containing the top left corner.

%Y The y-coordinate of the selection with coordinates relative to the output

containing the top left corner.

%W The width of the selection cropped to the output containing the top left

corner.

%H The height of the selection cropped to the output containing the top left

corner.

%l Label included with region from stdin

%o The name of the output containing the top left corner, or "<unknown>" if

not known

The default format is "%x,%y %wx%h\n".

KEYBOARD CONTROLS

The following keyboard actions can be used during selection:

Escape Cancel the selection and exit slurp

Space If currently making a selection, while space is held down, move the entire selection rather than change the selection's size as you move the pointer.

Shift Experimental. If the -a option wasn't specified, then set the aspect ratio to 1:1 while shift is held down, releasing it restores the un-constrained aspect ratio. Note: This behavior may change in the future depending on feedback.
