ମଡ୍ୟୁଲ:Year in various calendars

Script error: No such module "Year in other calendars".

Script error: No such module "Year in other calendars".

This module produces the sidebar opposite displaying a given Gregorian year in various different calendars.

Syntax

ସମ୍ପାଦନା

Simple 

{{#invoke:Year in other calendars|main}}

All parameters 

{{#invoke:Year in other calendars|main |year=(n) |footnotes=(footnotes) |gregcal=(article name)}}

Parameters

ସମ୍ପାଦନା
year
Number specifying the year to be displayed. This can be negative and also can be in the format "n BC" to display BC dates. If not specified, the current year is used.
footnotes
Any footnotes to be placed at the bottom of the sidebar.
gregcal
Name of an article to be displayed for Gregorian and Julian years (e.g. "2000 BC"). Do not include square brackets.

Microformat

ସମ୍ପାଦନା

The HTML mark up produced by this template includes an hCalendar microformat, which makes the event/ date details parsable by computers, either acting automatically to catalogue article across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to a calendar or diary application. For more information about the use of microformats on Wikipedia, please see the microformat project.

hCalendar uses HTML classes including:

  • attendee
  • description
  • dtend
  • dtstart
  • location
  • summary
  • url
  • vevent

Please do not rename or remove these classes; nor collapse nested elements which use them.


Adding new calendars

ସମ୍ପାଦନା

The module is set up to allow for easy addition of new calendars. Just scroll down to the "Build the box" section of the module code, and add your calendar as follows:

To display one year: 

    local myCalendar = calendar:new()
    myCalendar:setLink( 'My calendar article' ) -- The name of the calendar's Wikipedia article.
    myCalendar:setYear( year + 10 ) -- Lua code linking the Gregorian calendar year to your calendar's year.
    box:addCalendar( myCalendar )

To display a year range: 

    local myCalendar = calendar:new()
    myCalendar:setLink( 'My calendar article' ) -- The name of the calendar's Wikipedia article.
    myCalendar:setYearRange( year + 10, year + 11 ) -- Lua code outputting the start year and the end year of the year range.
    box:addCalendar( myCalendar )

More complicated calendars can be passed as a string to calendar:setYear().

Technical details

ସମ୍ପାଦନା

The module defines three classes which do the work of setting up the sidebar and displaying the data provided by the calendar functions. These are the calendarBox class, which defines the sidebar; the calendar class, which holds the data for one calendar; and the calendarGroup object, which defines a group of calendar objects with a heading.

To load these classes from another module, use the following: 

local yearInOtherCalendars = require( 'Module:Year in other calendars' )
local calendarBox = yearInOtherCalendars.calendarBox
local calendarGroup = yearInOtherCalendars.calendarGroup
local calendar = yearInOtherCalendars.calendar

calendarBox class

ସମ୍ପାଦନା

A calendarBox object is initiated with: 

local myCalendarBox = calendarBox:new{ year = yyyy, footnotes = footnotes, navbar = page name }
  • year - sets the Gregorian year to base calendar calculations on. If not specified, the current year is used.
  • footnotes - sets text to be displayed in a footnotes section at the bottom of the sidebar.
  • navbar - sets the page name to be used by the navbar.

Calendar box objects have the following properties:

  • calendarBox.year - the Gregorian year number. This is negative for BC years; for example, for the year 100 BC the value of calendarBox.year is -99. (BC years are calculated by "1 - n" rather than "0 - n", as there is no year zero.)
  • calendarBox.yearText - the Gregorian year text. This is a string value of the format "n" for AD years and "n BC" for BC years.
  • calendarBox.caption - the text of the box caption (the bold text that appears directly above the box). The default caption is the value of calendarBox.yearText.
  • calendarBox.footnotes - the text of the box footnotes.
  • calendarBox.navbar - the page name used by the navbar.

Calendar box objects have the following methods:

  • calendarBox:setCaption( caption ) - sets the box caption (the bold text that appears directly above the box). The default caption is the value of calendarBox.yearText.
  • calendarBox:addCalendar( obj ) - adds a calendar object or a calendar group object to the calendar box.
  • calendarBox:addCalendarGroup( obj ) - an alias for myCalendarBox:addCalendar().
  • calendarBox:export() - converts the calendar box object to wikicode. This calls calendar:export() and calendarGroup:export() to export calendar objects and calendar group objects.

calendar class

ସମ୍ପାଦନା

A calendar object is initiated with: 

local myCalendar = calendar:new()

Calendar objects have the following properties:

  • calendar.link - the link name.
  • calendar.year - the year value. This is always a string value.

Calendar objects have the following methods:

  • calendar:setLink( link, display ) - sets the link name for the calendar object. link is the name of Wikipedia's article about the calendar, and display is an optional display name for the article link.
  • calendar:setRawLink( wikitext ) - sets the calendar link as raw wikitext.
  • calendar:getLink() - gets the link value.
  • calendar:setYear( year ) - sets the year value for the calendar. year can be a number or a string.
  • calendar:setYearRange( startYear, endYear ) - sets the year value for the calendar as a year range. Both startYear and endYear must be number values.
  • calendar:export() - exports the calendar to wikitext. If no link value was found, this returns nil. If a link was found but no year value was found, the calendar is output with a value of N/A for the year.

calendarGroup class

ସମ୍ପାଦନା

A calendarGroup object is initiated with: 

local myCalendarGroup = calendarGroup:new{ heading = heading }
  • heading - the wikitext heading for the calendar group (e.g. [[Hindu calendar]]s).

Calendar group objects have one property:

  • calendarGroup.heading - the calendar group heading text.

Calendar group objects have the following methods:

  • calendarGroup:addCalendar( obj ) - adds a calendar object to the calendar group.
  • calendarGroup:export() - converts a calendar group to wikitext. Calls calendar:export() to export individual calendar objects.
