Flags

Flag	Default	Description
--duration	0s	Bound the loop. 0s means run until a key is pressed or SIGINT arrives.
--no-tips	false	Suppress the rotating tip line.
--seed	0	Seed the tip-rotation order. 0 means time-based.
--ascii	false	Force the kaomoji-only static fallback even on a capable terminal.

Examples

Run the animation until you press a key:

glacier vibe

Run for exactly 10 seconds (useful in scripts):

glacier vibe --duration=10s

Show the animation without tips:

glacier vibe --no-tips

Force the static fallback (useful on a terminal that does not support raw mode):

glacier vibe --ascii

Reproducible tip order (useful for screenshots):

glacier vibe --seed=42 --duration=5s

What it does under the hood

vibe detects terminal capabilities via term.Capability. On a TTY without --ascii, it acquires raw mode with term.AcquireRaw so a single keypress exits cleanly, then hands control to a term.Animator running at 100ms per frame. Each frame is rendered by vibeAnimation.Render: the bear expression cycles through three kaomoji every 30 ticks (3 seconds), and the tip rotates every 50 ticks (5 seconds) from the 12-tip registry in cmd/glacier/internal/vibetips. The result is wrapped in a term.Box with rounded corners and padding. When stdout is not a TTY, when --ascii is set, or when raw mode is unavailable, the command falls back to a single printed frame (kaomoji + wordmark + tagline + one tip) and exits 0.

Exit codes

Code	Meaning
0	Success or clean keypress exit
1	Animation setup failed
130	SIGINT (Ctrl-C)
143	SIGTERM
