/*	SUBJECT'S AGE FROM YEAR Description: In an article about a person or a company, when the mouse hovers over a year in the article, the age of the article's subject by that year appears in a tooltip. Link: User:Gary King/subjects age from year.js TODO Show age of item for establishments on death year. TODO For biographies with no birth year but with a death year (Cyrus the Great, Leonidas I), make dates relative to death year instead so that they stil work. TODO For articles with more than one category beginning with a number, like Babe Ruth, use the year closest to the present year. if (typeof(unsafeWindow) != 'undefined') {	var console = unsafeWindow.console; mw = unsafeWindow.mw; } var fromYearType; function fromYearPhrases(phrase) {	// fromYearType var phrases = { 'biography': { 'birth': 'birth', 'death': 'death' }, 'establishment': { 'birth': 'established', 'death': 'disestablished' } }; return phrases[fromYearType][phrase]; } function subjectsAgeFromYear {	function findYearsInText(node) {		if (node[0].nodeType != 3) return true; var nodeText = node[0].nodeValue; var years = nodeText.match(patterns[l]); if (!years) return true; var newNode = $(' '); // loop through each year in the same text node for (var k = 0; k < years.length; k++) {			var abbrText = currentYear = years[k]; var birthYearIndex = nodeText.indexOf(currentYear); var workThisYear = true; // don't work on this year—for AD years if (l == 0 && ( // 'year' is followed by a ' BC'; wait for next pattern to work on this nodeText.substr(birthYearIndex + currentYear.length, 3).indexOf('BC') != -1 // 'year' is preceded by a ','; this is probably a unit such as 1,000 km				|| nodeText.substr(birthYearIndex - 1, 1).indexOf(',') != -1 // 'year' is preceded by a month; this is probably part of a day, like "January 1" || (currentYear.length <= 2 && (nearAMonth(nodeText, birthYearIndex, -1, years, k) && currentYear.indexOf('AD') == -1)				// 'year' is followed by a month; this is probably part of a day, like "January 1"				|| nearAMonth(nodeText, birthYearIndex + currentYear.length, 1)) // 'year' is followed by a hyphen; this is probably part of a longer phrase // || nodeText.substr(birthYearIndex + currentYear.length, 1).indexOf('-') != -1 // 'year' is followed by "years", indicating a length, or relative date, as opposed to an absolute date // || nodeText.substr(birthYearIndex + currentYear.length, 6).indexOf('years') != -1 // 'year' is followed by "?year", such as "-year", " years" || nodeText.substr(birthYearIndex + currentYear.length, 5).indexOf('year') != -1 ))				workThisYear = false; if (currentYear.indexOf('BC') != -1 || ((birthYear < 0 || deathYear < 0) && nodeText.substr(birthYearIndex + currentYear.length + ' BC'.length, 10).indexOf('BC') != -1)) var currentYear = -1 * parseInt(currentYear); else if (currentYear.indexOf('AD') != -1 || currentYear.indexOf('CE') != -1) var currentYear = parseInt(currentYear.replace(/AD/, ).replace(/CE/, )); var firstPart = nodeText.substring(0, birthYearIndex); var difference = currentYear - birthYear; // find a year to act on; work on AD years first, then BC years if (workThisYear && (currentYear >= birthYear || currentYear >= (birthYear - birthYearBuffer)) && (currentYear <= deathYear || currentYear <= (deathYear + birthYearBuffer))) {				var abbr = $(' '); // after death year but before the buffer if (currentYear > deathYear && currentYear <= (deathYear + birthYearBuffer)) {					var yearsLater = currentYear - deathYear; abbr.attr('title', yearsLater + ' ' + pluralize('year', yearsLater) + ' after ' + fromYearPhrases('death')); }				// was alive at currentYear else if (difference >= 0) {					// age at currentYear abbr.attr('title', difference + ' ' + pluralize('year', difference) + ' old'); // birth year if (difference == 0) abbr.attr('title', abbr.attr('title') + ' (' + fromYearPhrases('birth') + (fromYearType == 'biography' && isAlive ?
