import RaStanza from './raStanza.ts';
/**
 * Class representing an ra file. Each file is composed of multiple stanzas,
 * separated by one or more blank lines. Each stanza is stored in the `data`
 * record, keyed by the value of the first key-value pair in the stanza. Lines
 * that are entirely comments (`#`) and `include` directives are skipped.
 * @property {undefined|string} nameKey - The key of the first line of all the
 * stanzas (`undefined` if the file has no stanzas yet).
 * @throws {Error} Throws if an empty stanza is added, if the key in the first
 * key-value pair of each stanza isn't the same, or if two stanzas have the same
 * value for the key-value pair in their first lines.
 * @param {(string|string[])} [raFile=[]] - An ra file, either as a single
 * string or an array of strings with one stanza per entry. Supports both LF
 * and CRLF line terminators.
 * @param {object} [options]
 * @param {boolean} [options.checkIndent=true] - Check that the stanzas within
 * the file are indented consistently and keep track of the indentation
 * @param {boolean} [options.skipValidation=false] - Skip the subclass
 * validation step
