When to use this skill

CRITICAL TRIGGER RULE

• Use this skill ONLY when the user explicitly mentions the exact skill name: ascii-progress-and-spinner.

Trigger phrases include:

• "ascii-progress-and-spinner"
• "use ascii-progress-and-spinner"
• "用 ascii-progress-and-spinner 生成 ASCII 进度条"
• "使用 ascii-progress-and-spinner 做 spinner / loading"

Boundary

• Do not integrate a specific UI framework; output styles + refresh rules + fallback protocol + examples.
• Must cover:
  • determinate progress bars
  • indeterminate spinners
  • non-TTY / redirected-output fallback (log lines, no carriage-return updates)

How to use this skill

Inputs

• mode (determinate | indeterminate)
• width (default 40)
• showPercent (default true)
• showEta (optional)
• multiTask (optional)
• colorMode (none | ansi256, default none)

Outputs (required)

• progressBarStyles (>= 3)
• spinnerStyles (>= 2)
• renderRules (TTY single-line refresh vs logLines)
• fallbackRules (non-interactive / redirected output)

Recommended render rules

• TTY (interactive): single-line refresh (overwrite previous line), avoid log spam
• Non-TTY (logs): print log lines (no overwrite). Each line may include task name + percent.

Inline Style Examples

Progress bar styles:

Style 1 (block):   [████████░░░░░░░░░░░░]  42%  ETA 3s
Style 2 (hash):    [########............]  42%  ETA 3s
Style 3 (arrow):   [========>-----------]  42%  ETA 3s

Spinner styles:

Style 1 (braille): ⠋ Loading...  →  ⠙ Loading...  →  ⠹ Loading...
Style 2 (pipe):    | Loading...  →  / Loading...  →  - Loading...

Non-TTY log fallback:

[task-1] 25% complete
[task-1] 50% complete
[task-1] 75% complete
[task-1] 100% complete - done (4.2s)

Workflow

1. Determine mode: determinate (known total) or indeterminate (spinner)
2. Select styles from the style gallery (>= 3 progress, >= 2 spinner)
3. Define render rules: TTY uses single-line refresh, non-TTY uses log lines
4. Define fallback rules for redirected output (no carriage returns)
5. Validate: Fixed-width percent field, no jitter, grep-friendly log mode

Script

• scripts/demo.py: local demo for progress bar + spinner shapes

Examples

• examples/styles.md

Quality checklist

1. Fixed width (percent field is fixed-width to avoid jitter)
2. Log mode is grep-friendly (no overwrite)
3. ASCII-only defaults are available (avoid ambiguous-width Unicode)
