✨ noof ✨

okay so bestie, we're talking about noof(6) — that's the XScreenSaver manual page, and honestly? it's giving "small but mighty" 💫 it draws rotatey patterns, and it does it with OpenGL. that's the whole vibe. short king of a manpage, and we love that for it 🎀

🌸 SYNOPSIS 🌸

noof [--display host:display.screen] [--visual visual] [--window]
[--root] [--window-id number] [--delay number] [--fps]

like, that's the whole invocation. no notes. slay. 💅

🦋 DESCRIPTION 🦋

it draws some rotatey patterns. using OpenGL. that's it, that's the plot 😭 no cap, the original really does keep it that brief, and honestly the brevity is iconic 👑

🎀 OPTIONS 🎀

  • --visual visual — tells it which visual to use. the legal values are either the name of a visual class, or the id number of a specific visual (and that number can be in decimal or hex, so you've got options fr fr ✨)
  • --window — draws on a newly-created window. this is the default, so if you do nothing, this is what you get 🫶
  • --root — draws on the root window instead 🌈
  • --window-id number — draws on the specific window you name 👀
  • --delay number — the per-frame delay, measured in microseconds. default is 10000, which is 0.01 seconds. tiny little pause, tiny little pause 💜
  • --fps — displays the current frame rate, the CPU load, and the polygon count. basically a little stats moment, iykyk 📊

🧚 ENVIRONMENT 🧚

  • DISPLAY — used to get the default host and display number 🖥️
  • XENVIRONMENT — used 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 🪟
