score.relatime

Lightweight humanized relative time formatting, inspired by Moment.js

Quickstart

<script src="score.init.js"></script>
<script src="score.relatime.js"></script>
<script>
    score.relatime(new Date());
    // 'a few seconds ago';
    score.relatime("2015-10-21", "1985-10-25");
    // 'in 30 years';
    score.relatime("1955-11-12", "1985-10-25", {future: "Marty travelled %s back to the future"});
    // 'Marty travelled 30 years back to the future';
</script>

Details

Grammar

An Object consisting of key/value pairs used to format the time span.

default grammar

{
    future: 'in %s',
    past: '%s ago',
    s: 'a few seconds',
    ss: 'a few seconds',
    m: 'a minute',
    mm: '%d minutes',
    h: 'an hour',
    hh: '%d hours',
    d: 'a day',
    dd: '%d days',
    M: 'a month',
    MM: '%d months',
    y: 'a year',
    yy: '%d years'
}

Negative time spans will use the past key, positive time spans the future key as the base string.

changing the base string

var grammar = {
   past: "Marty McFly arrived in the future %s ago",
   future: "Marty McFly will arrive in the future in %s"
}

score.relatime("2015-10-21", "2016-10-21", grammar);
// "Marty McFly arrived in the future a year ago"

score.relatime("2015-10-21", "2013-10-21", grammar);
// "Marty McFly will arrive in the future in 2 years"

Grammars can be used for i18n:

var grammar = {
    future : 'in %s',
    past : 'vor %s',
    s : 'ein paar Sekunden',
    ss : 'ein paar Sekunden',
    m: 'einer Minute',
    mm : '%d Minuten',
    h: 'einer Stunde',
    hh : '%d Stunden',
    d: '%d Tag',
    dd: '%d Tagen',
    M: 'einem Monat',
    MM: '%d Monaten',
    y: 'einem Jahr',
    yy: '%d Jahren'
};

var localized = score.relatime.create(grammar);
localized(new Date());
// "vor ein paar Sekunden"

Changing the base string from the localized function

var variant = localized.create({past: "seit %s"});
variant(new Date());
// "seit ein paar Sekunden"

API

function score.relatime(date, relDate, grammar)

Returns a humanized string representation for the time span between a given date and the current time.

The date can be an instance of Date(), a timestamp or a string that will be parsed by the browser's native Date() function. But be careful, cross-browser JavaScript Date parsing behavior is an issue on older Browsers.

The optional relDate accepts the same formats as date and will serve as the base date to compare the actual date to.

It is also possible to override (parts of) the conversion strings by passing a grammar object. The expected format for this object can be found in the Grammar section, above.

function score.relatime.create(grammar)

Returns a new score.relatime function, bound to the given grammar.

The expected format for the grammar argument can be found in the Grammar section, above.
