nano-base

Tiny base converter (2..36) — ~1 KB, zero deps. 255 → FF (base 10→16), FF → 11111111 (16→2), negatives supported. Perfect for code-golf, minimal containers, or just for fun.

✨ Features

• ✅ Convert between any bases 2..36 (digits 0-9A-Z, case-insensitive)
• ✅ Two forms:
  • <value> <to_base> (assumes from=10)
  • <value> <from_base> <to_base>
• ✅ Handles negatives, 0

🚀 Usage

# Local (from repo)
python app_min.py 255 16        # FF
python app_min.py FF 16 2       # 11111111
python app_min.py -42 10 16     # -2A

After installing:

# CLI
pip install nano-base
nano-base 255 16                # -> FF
nano-base FF 16 2               # -> 11111111
nano-base -2A 16 10             # -> -42

🤓 Why so small?

• Uses int(s, base) + tiny loop to format in target base
• No bigint libs; Python int already arbitrary precision
• Single tiny file + tiny CLI: perfect for scripts, containers, CI.

🎉 Fun Ideas

• Hex table (0..255)

for i in $(seq 0 255); do printf "%3d -> %s\n" $i "$(nano-base $i 16)"; done

• Binary width (pad with printf)

printf "%08d\n" "$(nano-base 42 2)"   # 000101010 (pad separately)

• Base36 IDs

nano-base 123456789 10 36   # -> 21I3V9

Note: Valid range is bases 2..36; input is case-insensitive (a..z ≡ A..Z).
