TOML 포매터

import { parse, stringify } from '@iarna/toml'
import fs from 'fs'

const raw = fs.readFileSync('config.toml', 'utf-8')
const doc = parse(raw)
const formatted = stringify(doc)
// stringify() outputs canonical TOML with consistent spacing
fs.writeFileSync('config.toml', formatted)

// Quick one-liner with npx:
// npx taplo fmt config.toml

import tomllib   # Python 3.11+ (read-only)
import tomli_w   # pip install tomli-w (write)

# Parse and re-serialize to format
with open("config.toml", "rb") as f:
    data = tomllib.load(f)

formatted = tomli_w.dumps(data)
# tomli_w produces sorted keys, consistent quoting, and
# proper whitespace around = signs
print(formatted)

# CLI alternative: taplo fmt config.toml
