Extension:JsCalendar (based on https://github.com/serpent213/mediawiki-extensions-yasec )

JsCalendar

NOTE: this is based on another extension: https://github.com/improper/mediawiki-extensions-yasec ... but doesn't aim to maintain backward compatibility with it.

Outputs a tabular calendar filled with events automatically generated from page titles in a certain namespace. Based on the intersection extension and the FullCalendar jQuery plugin.

Demo: FoodHackingBase Events

Usage

Assuming that event pages are called Event:Today_in_History/April,_12 (where Event is a namespace), the following wikitext will display a calendar of these events:

<EventCalendar>
namespace = Event
aspectratio = 1.35
prefix = Today_in_History/
suffix = 
dateFormat = F,_j
</EventCalendar>

... here F_j is the format from https://www.php.net/manual/ru/datetime.createfromformat.php - "F" means "name of month", and "j" means "day (with leading zero)".

Everything between "prefix" and "suffix" should be a date.

Alternatively, titleRegex parameter can be used to find event pages. For example, the following wikitext will find pages like Event:2020/05/15_Name_of_some_event:

<EventCalendar>
namespace = Event
titleRegex = ^([0-9]{4,4}/[0-9][0-9]/[0-9][0-9])_.*
dateFormat = Y/m/d
</EventCalendar>

When using titleRegex, the date part (in example above - [0-9]{4,4}/[0-9][0-9]/[0-9][0-9]) must be surrounded in "(" and ")" symbols (otherwise the calendar wouldn't know "which part of the title is the date").

aspectratio is optional and defaults to 1.6. CSS max-width is set to 800px and can be overridden in MediaWiki:Common.css.

Category-based coloring

The following parameters within <EventCalendar> will change the color of events to red/green based on the category into which the Event: page is included. Pages not included into any listed categories would have default color.

categorycolor.Cat-related events = red
categorycolor.Dogs = green

Keyword-based coloring

The following parameter within <EventCalendar> will change the color of event to yellow if the page contains the word "arctic" (the match is case-insensitive, so "Arctic" will work too), and to lightgreen if the page contains the word "statistically":

keywordcolor.arctic = yellow
keywordcolor.statistically = lightgreen

Requirements

• MediaWiki 1.34
• MySQL (this extension doesn't support PostgreSQL. Patches that add PostgreSQL support are very welcome, but maintainter of this extension won't be implementing this himself).

Installation

1. Deploy the files to extensions/JsCalendar.
2. Edit your LocalSettings.php:

   • Load the extension:

     wfLoadExtension( 'JsCalendar' );

   • Setup your namespace:

     $wgExtraNamespaces = array(
         100 => "Event",
         101 => "Event_talk",
     );
     $wgNamespacesToBeSearchedDefault = array(
         NS_MAIN => true,
         100     => true,
     );

   • For testing you might want to disable the cache:

     # How long to cache pages using EventCalendar in seconds. Default to 1 day.
     # Set to false to use the normal amount of page caching (most efficient),
     # set to 0 to disable cache altogether (inefficient, but results will never
     # be outdated)
     $wgECMaxCacheTime = 60*60*24;   // How long to cache pages in seconds
