What indentation style does the formatter use?

Each nested block level is indented by 4 spaces. Opening braces stay on the same line as the block name, and closing braces are on their own line, matching the nginx official style.

Are comments preserved?

Yes — lines starting with # are treated as comments and preserved exactly as-is, placed above the directive they annotate.

Does it validate nginx syntax?

No — the formatter is purely structural. It reindents based on { and } braces. For full nginx syntax validation, run nginx -t on your server.
