✨ goop — the squishy transparent oil & bubble screenhack ✨

okay bestie, so this page is from the XScreenSaver manual, and goop is that little program that makes your screen look like a lava lamp went to the spa. Let's get into it 💅

💖 NAME

goop — squishy transparent oil and bubble screenhack 🫧

🌸 SYNOPSIS

goop [--display host:display.screen] [--foreground color] [--background
color] [--window] [--root] [--window-id number][--mono] [--install]
[--visual visual] [--transparent] [--non-transparent] [--additive]
[--subtractive] [--xor] [--no-xor] [--fps]

🦋 DESCRIPTION

So basically, the goop program draws a whole simulation of bubbles floating around in layers of overlapping multicolored translucent fluid. it's giving ✨oil slick✨ and honestly? iconic. no cap. 🔥

🎀 OPTIONS

goop accepts the following options, and bestie, we are listing every single one:

  • --window — draw on a newly-created window. This is the default, so if you don't say anything, this is what you get 💖
  • --root — draw on the root window.
  • --window-id number — draw on the specified window. like, that exact one. be specific, queen.
  • --mono — if you're on a color display, pretend we're on a monochrome display. delulu is the solulu 🫶
  • --install — install a private colormap for the window.
  • --visual visual — specify which visual to use. legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. hex is giving main character energy ngl.
  • --count integer — how many bubbles to draw per layer. Default: random. 🫧
  • --planes integer — how many planes to draw. Default: random, based on screen depth.
  • --delay microseconds — how much of a delay should be introduced between steps of the animation. Default 12000, or about 0.012 seconds. tiny lil pause, literally.
  • --transparent — if --layers is greater than 1, then each layer will be drawn in one color, and when they overlap, the colors will be mixed. This is the default. 🎨
  • --non-transparent — turns off --transparent. bye transparency 👋
  • --additive — if --transparent is specified, then this option means that the colors will be mixed using an additive color model, as if the blobs were projected light. This is the default. ✨ glow-y vibes
  • --subtractive — if --transparent is specified, then this option means that the colors will be mixed using a subtractive color model, as if the blobs were translucent filters. 🍓 stained glass moment
  • --xor — draw with xor instead of the other color tricks. chaos mode, lowkey 🔀
  • --no-xor — the other one. (it's in the synopsis, bestie, we don't make the rules) 🙈
  • --fps — display the current frame rate and CPU load. so you can see exactly how hard your poor little CPU is working 😭

🌈 ENVIRONMENT

  • DISPLAY — to get the default host and display number. she tells goop where to show up 💖
  • XENVIRONMENT — to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
  • XSCREENSAVER_WINDOW — the window ID to use with --root. 👑
