How it works

The parser turns headers, keys, repeated values, and nested dot sections into an object, then serializes that object as canonical INI text. Original trivia is regenerated rather than preserved byte-for-byte.

  • The installed serializer supplies one deterministic output style.
  • No dialect-specific spacing option is assumed.

Worked example

PostgreSQL and app config sections
Format an INI configuration file with multiple sections
Input
											[database]
host=localhost
port=5432
[app]
debug=true
Output
												[database]
host=localhost
port=5432

[app]
debug=true

When to use this

Node package settings, desktop preferences, and fixture normalization use canonical INI output.

Edge cases

  • Comments and original alignment can disappear during object serialization.
  • Repeated keys may become arrays under parser conventions.
  • Dot-separated section names can serialize as nested sections.
