Notes: * 1. "Formatting" units (e.g. formatting quarter) in the default en-US locale * are the same as "stand-alone" units, but are different in some languages. * "Formatting" units are declined according to the rules of the language * in the context of a date. "Stand-alone" units are always nominative singular. * In `format` function, they will produce different result: * * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'` * * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'` * * `parse` will try to match both formatting and stand-alone units interchangeably. * * 2. Any sequence of the identical letters is a pattern, unless it is escaped by * the single quote characters (see below). * If the sequence is longer than listed in table: * - for numerical units (`yyyyyyyy`) `parse` will try to match a number * as wide as the sequence * - for text units (`MMMMMMMM`) `parse` will try to match the widest variation of the unit. * These variations are marked with "2" in the last column of the table. * * 3. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales. * These tokens represent the shortest form of the quarter. * * 4. The main difference between `y` and `u` patterns are B.C. years: * * | Year | `y` | `u` | * |------|-----|-----| * | AC 1 | 1 | 1 | * | BC 1 | 1 | 0 | * | BC 2 | 2 | -1 | * * Also `yy` will try to guess the century of two digit year by proximity with `referenceDate`: * * `parse('50', 'yy', new Date(2018, 0, 1)) //=> Sat Jan 01 2050 00:00:00` * * `parse('75', 'yy', new Date(2018, 0, 1)) //=> Wed Jan 01 1975 00:00:00` * * while `uu` will just assign the year as is: * * `parse('50', 'uu', new Date(2018, 0, 1)) //=> Sat Jan 01 0050 00:00:00` * * `parse('75', 'uu', new Date(2018, 0, 1)) //=> Tue Jan 01 0075 00:00:00` * * The same difference is true for local and ISO week-numbering years (`Y` and `R`), * except local week-numbering years are dependent on `options.weekStartsOn` * and `options.firstWeekContainsDate` (compare [setISOWeekYear](https://date-fns.org/docs/setISOWeekYear) * and [setWeekYear](https://date-fns.org/docs/setWeekYear)). * * 5. These patterns are not in the Unicode Technical Standard #35: * - `i`: ISO day of week * - `I`: ISO week of year * - `R`: ISO week-numbering year * - `o`: ordinal number modifier * - `P`: long localized date * - `p`: long localized time * * 6. `YY` and `YYYY` tokens represent week-numbering years but they are often confused with years. * You should enable `options.useAdditionalWeekYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * * 7. `D` and `DD` tokens represent days of the year but they are often confused with days of the month. * You should enable `options.useAdditionalDayOfYearTokens` to use them. See: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * * 8. `P+` tokens do not have a defined priority since they are merely aliases to other tokens based * on the given locale. * * using `en-US` locale: `P` => `MM/dd/yyyy` * using `en-US` locale: `p` => `hh:mm a` * using `pt-BR` locale: `P` => `dd/MM/yyyy` * using `pt-BR` locale: `p` => `HH:mm` * * Values will be assigned to the date in the descending order of its unit's priority. * Units of an equal priority overwrite each other in the order of appearance. * * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year), * the values will be taken from 3rd argument `referenceDate` which works as a context of parsing. * * `referenceDate` must be passed for correct work of the function. * If you're not sure which `referenceDate` to supply, create a new instance of Date: * `parse('02/11/2014', 'MM/dd/yyyy', new Date())` * In this case parsing will be done in the context of the current date. * If `referenceDate` is `Invalid Date` or a value not convertible to valid `Date`, * then `Invalid Date` will be returned. * * The result may vary by locale. * * If `formatString` matches with `dateString` but does not provides tokens, `referenceDate` will be returned. * * If parsing failed, `Invalid Date` will be returned. * Invalid Date is a Date, whose time value is NaN. * Time value of Date: http://es5.github.io/#x15.9.1.1 * * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc). * @typeParam ResultDate - The result `Date` type, it is the type returned from the context function if it is passed, or inferred from the arguments. * * @param dateStr - The string to parse * @param formatStr - The string of tokens * @param referenceDate - defines values missing from the parsed dateString * @param options - An object with options. * see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * * @returns The parsed date * * @throws `options.locale` must contain `match` property * @throws use `yyyy` instead of `YYYY` for formatting years using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * @throws use `yy` instead of `YY` for formatting years using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * @throws use `d` instead of `D` for formatting days of the month using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * @throws use `dd` instead of `DD` for formatting days of the month using [format provided] to the input [input provided]; see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * @throws format string contains an unescaped latin alphabet character * * @example * // Parse 11 February 2014 from middle-endian format: * var result = parse('02/11/2014', 'MM/dd/yyyy', new Date()) * //=> Tue Feb 11 2014 00:00:00 * * @example * // Parse 28th of February in Esperanto locale in the context of 2010 year: * import eo from 'date-fns/locale/eo' * var result = parse('28-a de februaro', "do 'de' MMMM", new Date(2010, 0, 1), { * locale: eo * }) * //=> Sun Feb 28 2010 00:00:00 */ function parse(dateStr, formatStr, referenceDate, options) { const invalidDate = () => (0, _index4.constructFrom)(options?.in || referenceDate, NaN); const defaultOptions = (0, _index5.getDefaultOptions)(); const locale = options?.locale ??
