🚂✨ trainmandala — the XScreenSaver manual, but make it cute ✨🚂

💖 NAME 💖

trainmandala — it's a screen saver. that's it. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

trainmandala [--display host:display.screen] [--visual visual]
[--window] [--root] [--delay number] [--speed number] [--scale number]
[--fps]

like, that's the whole invocation. she's lowkey minimal about it. 💅

🧚 DESCRIPTION 🧚

Enter the flowing ring.

no cap, that's the entire description in the original and I refuse to elaborate because neither did they. it's a ring. it flows. you enter it. ✨🔥

👑 OPTIONS 👑

  • --visual visual — tells it which visual to use. legal values are either the name of a visual class, or the id number of a specific visual (decimal or hex, both work, she's flexible 🫶).
  • --window — draws on a newly-created window. this is the default, so if you do nothing, congrats, you already did it. 💖
  • --root — draws on the root window instead. big "I want it everywhere" energy.
  • --delay number — per-frame delay, measured in microseconds. Default: 20000 (which is 0.02 seconds, for the people who don't think in microseconds, and honestly, same 😭).
  • --speed number — animation speed. 2.0 means twice as fast, 0.5 means half as fast. math, but make it fashion. 🌈
  • --scale number — resolution. range is 0.1 - 1.0. Default: 1.0. 🎀
  • --fps | --no-fps — whether to show a frames-per-second display at the bottom of the screen. yes that's a toggle, no it's not a mystery, you got this. ⭐

🦋 ENVIRONMENT 🦋

  • DISPLAY — used to get the default host and display number. classic X behaviour, love that for us. 💜
  • XENVIRONMENT — used to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. she's nosy about your config files and we respect it. 🙈
  • XSCREENSAVER_WINDOW — the window ID to use with --root. iykyk. 🌸
