Summary
Added
--statsflag to display token count comparison when encoding JSON to TOON.Usage
Output:
users[3]{id,name,role}:
1,Alice,admin
2,Bob,user
3,Charlie,user
ℹ Token estimate: 43 (JSON) → 18 (TOON)
✔ Saved ~25 tokens (58.1%)
Implementation
Uses simple approximation:
Math.ceil(text.length / 4)(GPT-style tokenizers average ~4 chars per token)
Why not use gpt-tokenizer:
If you prefer accuracy over simplicity, I can switch to gpt-tokenizer.
Screenshots
Added a small feature that seemed useful. Hope you can accept this PR if it looks good to you!
