Links

Internal Links

[[ThisIsALink]]

Internal links that get a label:

[[ThisIsTheLink|This is the label that shows up in text]]

External Links

External links that are rendered verbatim

http://cnn.com

External links that get a label

[http://something.com/something/else Local Label]

Note that "http:" can be omitted:

[//something.com/something/else Local Label]

If you want to avoid a text with an external link syntax to be automatically turned into a link, use <nowiki>:

<nowiki>http://cnn.com</nowiki>

Lists

* List item

Italics

''italics''

Bold

'''bold'''

Code and Fixed Typed Fonts

Code Section in a Box

 <pre>...</pre>

Indented Block

The alternative is to indent the block:

This is
an indented
block

Note that when using this method, MediaWiki is sensitive to the presence of '<source>' element. If you need to use it, use &lt immediately followed by ; to start the element.

However, this method is more flexible, as we can format the text:

This is
a block that contains bold sections and 
RED sections
End.

The size of the font in the indented block can be controlled with:

In somewhat smaller font.

In-Line Code

The in-line code is marked using the <code> HTML tag. It looks like this: this is some code. For more details, including how to change the rendering, see:

Media Wiki Concepts | <code>

In-Line no-formatting

<nowiki>...</nowiki>

Fixed Type Fonts

<tt> ... </tt>

Alternative highlight for Code

for i in "a b c"; do echo ${i}; done Use:

<font face='menlo' color='lightslategray' size='-1'>

for i in "a b c"; do echo ${i}; done

Paragraph Indentation

:One indent
::Two indents
:::Three indents
:::::: Multiple indent

Anchors and Linking to Anchors

An anchor is a in-page link target - it allows incoming links to target locations on the page other than section headings.

The anchors are automatically generated in case of the section headings. For example, a section named "Section One" generates a Section_One anchor, and the heading can be linked to by prepending "#Section_One" to the usual wiki #Links. In case of multiple sections with identical headings, the anchor names have a "_2", "_3", etc appended starting from the second occurrence.

Manual anchors can be also inserted and used in links:

<span id="anchor_name">text to anchor to</span>

or

<span id="anchor_name"></span>

Do not use:

<span id="anchor_name"/>

it won't work.

Anchor Names

Heading Name	Anchor
Test	#Test
Section One	#Section_One
Capitalization does Matter	Capitalization_does_Matter

Special Anchors

#toc links to the table of contents.

Preserving Old Anchors when a Heading Changes

If you want to change a heading to a more appropriate name, but want keep all existing links working, use the old anchor in a span inside the new heading, as follows:

=<span id='Old_Heading'></span>New Heading=

<blockquote style="background-color: #f9f9f9; border: solid thin lightgrey;">

Internal Link Template

Alternatively, use this parameterized template: Template:Internal. The first parameter is the target wiki page name, optionally followed by # an the anchor. The second parameter is the name of the link, as it will be rendered in the page.

<blockquote style="background-color: AliceBlue; border: solid thin LightSteelBlue;">
:some_external_link<br>
</blockquote>

http://example.com

External Link Template

Alternatively, use this parameterized templates: Template:External and Template:External2.

For External, the first and only parameter is the external link, or text and link:

{{External|http://example.com}}

{{External|something, something else: http://example.com}}

External2 allows for two stacked links.

If the link is to be hidden and exposed as a label:

{{ExternalLabel|http://example.com|example}}

<blockquote style="background-color: Gold; border: solid thin Goldenrod;">

</syntaxhighlight>

function test() {
  echo "this is a function"
}

where lang can be:

• bash
