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, %c,  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")
