iso8601-js-period

Javascript library for parsing of ISO 8601 durations. Supported are durations of the form P3Y6M4DT12H30M17S or PT1S or P1Y4DT1H3S etc.

For documentation of ISO 8601, see

API

All methods of this library are published within the namespace nezasa.iso8601.period. The following methods are currently available.

Method Array[int] nezasa.iso8601.period.parse(String period, Boolean distributeOverflow)

Takes a ISO 8601 formatted duration and returns an array with 6 elements, one per unit. The order of the units, starting with the first element of the array, is “year”, “month”, "week", “day”, “hour”, “minute”, “second”.

If "distributeOverflow" is set to "true", the overflows are distributed to the higher units.

Examples (distrubtedOverflow = false):

Examples (distrubtedOverflow = true):

Method int nezasa.iso8601.Period.parseToTotalSeconds(String period)

Takes a ISO 8601 formatted duration and returns the total amount of seconds represented by the duration.

Method String nezasa.iso8601.Period.parseToString(String period, Array[String] unitNames, Array[String] unitNamesPlural, Boolean distributeOverflow)

Takes a ISO 8601 formatted duration and returns a more natural representation of the period. In order to handle different languages, the method takes two input arrays two define the unit names in singular and plural, e.g., for English it would be

The English versions as shown above represent the default, thus the English unit names are used if unitNames and unitNamesPlural remain undefined.

If "distributeOverflow" is set to "true", the overflows are distributed to the higher units.

Change Log

A special note about backward compatibility. We hate breaking backward compatibility and try to avoid it. But this lib is tiny, so atm we rather go for new features than always sticking to backward compatibility. Nevertheless, the aim of this lib is to give nice support for ISO8601. By the static nature of ISOs, this lib should not change to much neither.
