TTE: Terminal Text Effects

Original Article ↗ Hacker News Discussion ↗

Overall reaction

  • Very positive reception; many describe the effects as beautiful, clever, and nostalgic.
  • Strong emotional response: people report smiling, feeling “wow,” and being reminded of 80s/90s BBSes, ANSI art, Commodore demos, roguelikes, and early “Matrix-style” hacks.
  • Some consider it one of the more delightful, whimsical projects they’ve seen on HN in a while.

Suggested use cases

  • Fun/non-critical contexts: splash screens, SSH MOTD/login banners, “about” screens, terminal game intros, roguelikes, MUDs/BBS doors, teaching/demos, and demoscene productions.
  • Developer-only tooling: scaffolding templates, build/deploy scripts, or package managers, especially as opt‑in themes or first-run-only effects.
  • Progress indicators and loading screens where time is already being spent (downloads, builds, compression, long-running commands).
  • Film/TV “hacker” scenes and retro‑cyberpunk aesthetics.

Concerns and pushback

  • Many warn against default use in serious or frequently used tools:
    • Animations can impede productivity and become annoying once the novelty wears off.
    • Debugging/log inspection users generally do not want animations.
  • Strong concern about slow or fragile connections (SSH over satellite, mosh, low‑baud terminals); animations could be unusable or harmful there.
  • Some argue terminals’ value is speed and simplicity; rich, GPU-heavy, 24‑bit animations feel out of place or should at least degrade gracefully on minimal terminals.

Controls, configuration, and ergonomics

  • Emphasis on making effects:
    • Fast or subtle for everyday use.
    • Disable‑able via flags, config, or environment variables (including NO_COLOR‑style conventions).
    • Potentially auto‑disabled on slow links or with TERM=dumb.
  • Suggestions for skipping/short‑circuiting animations via keypresses.

Technical notes and related tools

  • Implemented on top of ANSI escape codes with 24‑bit color; not a new terminal protocol.
  • Highly configurable: direction, speed, color, and specific variants for many effects.
  • Comparisons and connections to tools/libraries like notcurses, libcaca/AAlib, Chalk, charm.sh components, Emacs and Vim “screensaver” modes, and roguelikes such as Cogmind.
  • Some wish for more simple/quick effects and for terminal emulators to eventually support richer, structured capabilities (graphics protocols, forms, smarter stateful features).
