You’re awesome! :heart: ## Help We’re not able to provide support through GitHub Issues. If you’re looking for help with your code, try posting on [Stack Overflow](https://stackoverflow.com/). All features should be documented. If you don’t see a feature in the docs, assume it doesn’t exist. ## Bugs Think you’ve discovered a bug? 1. Search existing issues to see if it’s been reported. 2. Try the `master` branch to make sure it hasn’t been fixed. ```rb gem "pghero", github: "ankane/pghero" ``` If the above steps don’t help, create an issue. Include: - Detailed steps to reproduce - Complete backtraces for exceptions ## New Features If you’d like to discuss a new feature, create an issue and start the title with `[Idea]`. ## Pull Requests Fork the project and create a pull request. A few tips: - Keep changes to a minimum. If you have multiple features or fixes, submit multiple pull requests. - Follow the existing style. The code should read like it’s written by a single person. Feel free to open an issue to get feedback on your idea before spending too much time on it. --- This contributing guide is released under [CCO](https://creativecommons.org/publicdomain/zero/1.0/) (public domain).

| 2,7 | * 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: * * `format(new Date(2017, 10, 6), 'do LLLL', {locale: cs}) //=> '6. listopad'` * * `format(new Date(2017, 10, 6), 'do MMMM', {locale: cs}) //=> '6. listopadu'` * * 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 (e.g. `EEEEEEEEEEE`) * the output will be the same as default pattern for this unit, usually * the longest one (in case of ISO weekdays, `EEEE`). Default patterns for units * are marked with "2" in the last column of the table. * * `format(new Date(2017, 10, 6), 'MMM') //=> 'Nov'` * * `format(new Date(2017, 10, 6), 'MMMM') //=> 'November'` * * `format(new Date(2017, 10, 6), 'MMMMM') //=> 'N'` * * `format(new Date(2017, 10, 6), 'MMMMMM') //=> 'November'` * * `format(new Date(2017, 10, 6), 'MMMMMMM') //=> 'November'` * * 3. Some patterns could be unlimited length (such as `yyyyyyyy`). * The output will be padded with zeros to match the length of the pattern. * * `format(new Date(2017, 10, 6), 'yyyyyyyy') //=> '00002017'` * * 4. `QQQQQ` and `qqqqq` could be not strictly numerical in some locales. * These tokens represent the shortest form of the quarter. * * 5. 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` always returns the last two digits of a year, * while `uu` pads single digit years to 2 characters and returns other years unchanged: * * | Year | `yy` | `uu` | * |------|------|------| * | 1 | 01 | 01 | * | 14 | 14 | 14 | * | 376 | 76 | 376 | * | 1453 | 53 | 1453 | * * 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 [getISOWeekYear]{@link https://date-fns.org/docs/getISOWeekYear} * and [getWeekYear]{@link https://date-fns.org/docs/getWeekYear}). * * 6. Specific non-location timezones are currently unavailable in `date-fns`, * so right now these tokens fall back to GMT timezones. * * 7. 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 * - `t`: seconds timestamp * - `T`: milliseconds timestamp * - `o`: ordinal number modifier * - `P`: long localized date * - `p`: long localized time * * 8. `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 * * 9. `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 * * @param {Date|Number} date - the original date * @param {String} format - the string of tokens * @param {Object} [options] - an object with options. * @param {Locale} [options.locale=defaultLocale] - the locale object.

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 interchangably. * * 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]{@link https://date-fns.org/docs/setISOWeekYear} * and [setWeekYear]{@link 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 ofthen 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 * * @param {String} dateString - the string to parse * @param {String} formatString - the string of tokens * @param {Date|Number} referenceDate - defines values missing from the parsed dateString * @param {Object} [options] - an object with options. * @param {Locale} [options.locale=defaultLocale] - the locale object.

* see: https://github.com/date-fns/date-fns/blob/master/docs/unicodeTokens.md * @param {Boolean} [options.useAdditionalDayOfYearTokens=false] - if true, allows usage of the day of year tokens `D` and `DD`;
