Adding HTML5 Video to MediaWiki

To embed a youtube video, use the following code:


Extension LinkTitles

require_once( "$IP/extensions/LinkTitles/LinkTitles.php" );
$wgLinkTitlesSmartMode = false;         // false = case sensitive
$wgLinkTitlesMinimumTitleLength = 7;    // default is 3
$wgLinkTitlesSkipTemplates = true;      // skip any text in a {{template|text}}
$wgLinkTitlesFirstOnly = true;          // only link the first occurrence
$wgLinkTitlesBlackList = array();
$wgLinkTitlesBlackList[] = 'MediaWiki';
$wgLinkTitlesBlackList[] = 'mediaplayer';

Syntax Highlighting

The SyntaxHighlight extension, formerly known as SyntaxHighlight_GeSHi, provides rich formatting of source code using the <syntaxhighlight> tag. It is powered by the Pygments library and supports hundreds of different programming languages and file formats.


<syntaxhighlight lang="python" line='line'>
def quick_sort(arr):
	less = []
	pivot_list = []
	more = []
	if len(arr) <= 1:
		return arr
1 def quick_sort(arr):
2 	less = []
3 	pivot_list = []
4 	more = []
5 	if len(arr) <= 1:
6 		return arr
7 	else:
8 		pass



The lang="name" attribute defines what lexer should be used. The language affects how the extension highlights the source code.

<syntaxhighlight lang="python">
def quick_sort(arr):
    less = []

def quick_sort(arr):
    less = []


The line attribute enables line numbers.

<syntaxhighlight lang="python" line="1">
def quick_sort(arr):
    less = []

1 def quick_sort(arr):
2     less = []


<syntaxhighlight lang="python" line start="55">
def quick_sort(arr):
    less = []

55 def quick_sort(arr):
56     less = []


The highlight attribute specifies one or more lines that should be marked (by highlighting those lines with a different background color). You can specify multiple line numbers separated by commas (for example, highlight="1,4,8") or ranges using two line numbers and a hyphen (for example, highlight="5-7"). Note that the line number specification ignores any renumbering of the displayed line numbers with the start attribute.

<syntaxhighlight lang="python" highlight="1,5-7" start=3 line>
def quick_sort(arr):
    less = []
    pivot_list = []
    more = []
    if len(arr) <= 1:
        return arr

3 def quick_sort(arr):
4     less = []
5     pivot_list = []
6     more = []
7     if len(arr) <= 1:
8         return arr


The attribute indicates that the source code should be inline as part of a paragraph (as opposed to being its own block).

Note that line breaks can occur at any space between the opening and closing tags unless the source code is marked non-breakable with class="nowrap" (on those wikis that support it; see below) or style=white-space:nowrap. For example:

The following lambda x: x * 2 is a lambda expression in Python.

Is the result of:

The following <tvar|code><syntaxhighlight lang="python" inline>lambda x: x * 2</syntaxhighlight></> is a [[w:Lambda (programming)|lambda expression]] in Python.


When inline</> is used, class="nowrap" (on those wikis that support it; not on MediaWiki itself) specifies that line breaks should not occur at spaces within the code block. For example:

Without class="nowrap":

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxlambda x: x * 2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

With style="white-space:nowrap":

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxlambda x: x * 2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

References and Citations

Using Native Ref Tags

In-text references make it easy to copy the text to another page; on the other hand, they make it hard to read. References containing a lot of data, quotes or elaborate citation templates can make up a significantly larger fraction of the source than the text that will actually be visible. To avoid this, recent versions of the extension allow moving some or all of the references into the <references /> section, to the place where they will actually appear to the reader. Thus,

According to scientists, the Sun is pretty big.<ref name="miller" />
The Moon, however, is not so big.<ref name="smith" />

<ref name="miller">E. Miller, The Sun, (New York: Academic Press, 2005), 23-5.</ref>
<ref name="smith">R. Smith, "Size of the Moon", Scientific American, 46 (April 1978): 44-6.</ref>

will have the same output as the first example above, although the numbering and order of the references will not in general be the same.

Upgrading MediaWiki

Step 1 - download latest stable version of MediaWiki

Step 2 - determine database credentials from dreamhost

Get Hostname (e.g.)
Get Database name (e.g.)
  • bradleymonk_com
Get Database User name (e.g.)
  • username
Get Database User pass (e.g.)
  • password

Step 3 - back-up existing files and the database

  • Go to:
  • Enter db user and password when prompted
  • click on db in left panel
  • click on the "Export" tab
  • check "Save as file"
  • click "Go"

Step 4 - FTP the mediawiki.tar.gz file to the /w directory

Step 5 - Unpack the tarball

Use the console to SSH into the /w directory and unpack tarball
  • $ssh -l username
  • Change to the /w directory
  • $tar xvzf mediawiki.tar.gz
  • this unpacks into a new folder: /w/mediawiki

Step 6 - Move files and rename directory

Copy files from old to new directory
  • LocalSettings.php
  • logofile.png
  • images (or upload) directory
  • extension directory
  • custom skins
  • .htaccess file
Swap-rename directories
  • rename old directory /w_old
  • move new directory out of /w_old to top level domain
  • rename new directory to /w

Step 7 - Run MediaWiki update script

  • login with SSH again:
  • $ssh -l username
  • change to the /w/maintenance directory
  • enter: $php update.php

  • If the prompt gives an error like: "you're using php version 2.x mediawiki requires version 3.x"
  • try entering these:
  • $/usr/local/php53/bin/php update.php
  • $/usr/local/php54/bin/php update.php

Check if the upgrade worked by going to the MediaWiki page "Special Version"

MediaWiki Tips

  • To remove the arrow icon from external links, navigate to MediaWiki:Common.css and add this line of code
#content a[href ^="http://"].external {background: center right no-repeat; padding-right: 1px;}

Labeled Section Transclusion

See: Extension:Labeled_Section_Transclusion

Step 1: Mark off sections

Mark off sections in the text using <section></> tags like this:

    <section begin=Hayashi_Malinow_2000_Science />

    {{Article|Hayashi Malinow|2000|Science • PDF|10731148|Driving AMPA receptors into synapses}}

    <section end=Hayashi_Malinow_2000_Science />

Note that this uses two individual markers, rather than normal XML open/close tags, which simplifies nested or overlapping sections. This allows you to insert section tags without worrying about interfering with other sections.

Step 2: Transclude the section

Call the parser function to transclude it, i.e. to transclude a section called chapter1 from a page called Articles:
