SLOP(1)

NAME
slop - select operation

SYNOPSIS
slop [-klqn] [OPTIONS]

DESCRIPTION
slop is an application that queries for a selection from the user and prints the region to stdout. It grabs the mouse and turns it into a crosshair, lets the user click and drag to make a selection (or click on a window) while drawing a pretty box around it, then finally prints the selection's dimensions to stdout.

OPTIONS

-h, --help
    Print help and exit.

-v, --version
    Print version and exit.

-x, --xdisplay=hostname:number.screen_number
    Sets the xdisplay to use.

-b, --bordersize=FLOAT
    Sets the selection rectangle's thickness.

-p, --padding=FLOAT
    Sets the padding size for the selection, this can be negative.

-t, --tolerance=FLOAT
    How far in pixels the mouse can move after clicking, and still be detected as a normal click instead of a click-and-drag. Setting this to 0 will disable window selections. Alternatively setting it to 9999999 would force a window selection.

-c, --color=FLOAT,FLOAT,FLOAT,FLOAT
    Sets the selection rectangle's color. Supports RGB or RGBA input. Depending on the system's window manager/OpenGL support, the opacity may be ignored.

-r, --shader=STRING
    This sets the vertex shader, and fragment shader combo to use when drawing the final framebuffer to the screen. This obviously only works when OpenGL is enabled. The shaders are loaded from ~/.config/slop. See https://github.com/naelstrof/slop for more information on how to create your own shaders.

-f, --format=STRING
    Sets the output format for slop. Format specifiers are %x, %y, %w, %h, %i, and %g. If actual percentage signs are desired in output, use a double percentage sign like so `%%`.

-n, --nodecorations=INT
    Sets the level of aggressiveness when trying to remove window decroations. `0' is off, `1' will try lightly to remove decorations, and `2' will recursively descend into the root tree until it gets the deepest available visible child under the mouse. Defaults to `0'. Supplying slop with just `-n` is equivalent to supplying `-n1`.

-l, --highlight
    Instead of outlining a selection, slop will highlight it instead. This is particularly useful if the color is set to an opacity lower than 1.

-q, --quiet
    Disable any unnecessary cerr output. Any warnings simply won't print.

-k, --nokeyboard
    Disables the ability to cancel selections with the keyboard.

-o, --noopengl
    Disables graphics acceleration. Might be useful if you get rendering bugs.

EXAMPLES
To emulate a windows XP selection, you can use something like this:

    slop --highlight --tolerance=0 --color=0.3,0.4,0.6,0.4

In order to avoid using eval(1) in your scripts (pretty big security issue), you can use slop like this instead:

    read -r X Y W H G ID < <(slop -f "%x %y %w %h %g %i")
