Bun-flavored TOML

TOML is a minimal configuration file format designed to be easy for humans to read.

Bun implements a TOML parser with a few tweaks designed for better interopability with INI files and with JavaScript.

; and # are comments

In Bun-flavored TOML, comments start with # or ;

# This is a comment
; This is also a comment

This matches the behavior of INI files.

In TOML, comments start with #

# This is a comment

String escape characters

Bun-flavored adds a few more escape sequences to TOML to work better with JavaScript strings.
