import RaStanza from './raStanza';
/**
 * Class representing an ra file. Each file is composed of multiple stanzas, and
 * each stanza is separated by one or more blank lines. Each stanza is stored in
 * a Map with the key being the value of the first key-value pair in the stanza.
 * The usual Map methods can be used on the file. An additional method `add()`
 * is available to take a raw line of text and break it up into a key and value
 * and add them to the class. This should be favored over `set()` when possible,
 * as it performs more validity checks than using `set()`.
 * @property {undefined|string} nameKey - The key of the first line of all the
 * stanzas (`undefined` if the stanza has no lines yet).
 * @throws {Error} Throws if an empty stanza is added, if the key in the first
 * key-value pair of each stanze 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 if a the stanzas within
 * the file are indented consistently and keep track of the indentation
