The path uses . as a separator. Quoted segments are not supported here — if you need a key that contains a dot, use Document#get(path : Array(String)) with an explicit array of segments.

set(key : String, value : String) : Nil

Sets a top-level key to value. If a top-level KeyValueLine already exists for that key, only its value (and any trailing comment if comment is given) is replaced — surrounding whitespace and comments are preserved. Otherwise a new line is inserted at the end of the top-level section (before the first table header).

comment is the trailing comment text without the leading #. Pass an empty string to clear an existing trailing comment, nil to leave it untouched on update.

The current implementation operates on a single bare key. For dotted paths or values inside [section] blocks, see issue tracker — those are planned but not in v0.1.

set_with_comment(key : String, value : String, comment : String) : Nil

Same as #set but also sets a trailing inline comment on the line. The comment argument should not include the leading #; it is added automatically with a single space prefix.
