Help:Wikitext examples

Basic text formatting

You can format the page using Wikitext special characters.

What it looks like	What you type
You can italicize text by putting 2 apostrophes on each side. 3 apostrophes will bold the text. 5 apostrophes will bold and italicize the text. (Using 4 apostrophes doesn't do anything special -- 3 of them bold the text as usual; the others are 'just' apostrophes around the text.)	You can ''italicize'' text by putting 2 apostrophes on ''each'' side. 3 apostrophes will '''bold''' the text. 5 apostrophes will '''''bold and italicize''''' the text. (Using 4 apostrophes doesn't do anything special -- <br /> 3 of them '''bold''' the text as usual; the others are ''''just'''' apostrophes around the text.)
A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function (used internally to compare different versions of a page). But an empty line starts a new paragraph. When used in a list, a newline does affect the layout (see below).	A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the ''diff'' function (used internally to compare different versions of a page). But an empty line starts a new paragraph. When used in a list, a newline ''does'' affect the layout ([[#lists\|see below]]).
You can break lines without a new paragraph. Please use this sparingly. Please do not start a link or italics or bold text on one line and end on the next.

You should "sign" your comments on talk pages: Three tildes gives your signature: Example Four tildes give your signature plus date/time: Example 07:46, 27 November 2005 (UTC)[reply] Five tildes gives the date/time alone: 07:46, 27 November 2005 (UTC)	You should "sign" your comments on talk pages: * Three tildes gives your signature: ~~~ * Four tildes give your signature plus date/time: ~~~~ * Five tildes gives the date/time alone: ~~~~~

HTML tags

Main article: Help:HTML in wikitext

You can use some HTML tags, too. However, you should avoid HTML in favor of Wiki markup whenever possible.

What it looks like	What you type
Put text in a `monospace ('typewriter') font`. The same font is generally used for `computer code`.	Put text in a <kbd>monospace ('typewriter') font</kbd>. The same font is generally used for <code> computer code</code>.
~~Strike out~~ or underline text, or write it in small caps.	<s>Strike out</s> or <u>underline</u> text, or write it <span style= "font-variant:small-caps"> in small caps</span>.
Superscripts and subscripts: X², H₂O	Superscripts and subscripts: X<sup>2</sup>, H<sub>2</sub>O
Centered text Please note the American spelling of "center".	<div style="text-align: center;">Centered text</div> * Please note the American spelling of "center".

The blockquote command formats block quotations, typically by surrounding them with whitespace.	<blockquote> The '''blockquote''' command ''formats'' block quotations, typically by surrounding them with whitespace. </blockquote>
Invisible comments to editors (<!-- -->) appear only while editing the page. If you wish to make comments to the public, you should usually use the talk page.	Invisible comments to editors (<!-- -->) appear only while editing the page. <!-- Note to editors: blah blah blah. -->

Links

Main article: Help:Link

You will often want to make clickable links to other pages.

What it looks like	What you type
Here's a link to a page named Official position. You can even say official positions and the link will show up correctly.	Here's a link to a page named [[Official positions\|Official position]]. You can even say [[official positions]] and the link will show up correctly.
You can put formatting around a link. Example: Wikipedia.	You can put formatting around a link. Example: ''[[Wikipedia]]''.
The first letter of articles is automatically capitalized, so wikipedia goes to the same place as Wikipedia. Capitalization matters after the first letter.	The ''first letter'' of articles is automatically capitalized, so [[wikipedia]] goes to the same place as [[Wikipedia]]. Capitalization matters after the first letter.
Intentionally permanent red link is a page that doesn't exist yet. You could create it by clicking on the link.	[[Intentionally permanent red link]] is a page that doesn't exist yet. You could create it by clicking on the link.
You can link to a page section by its title: Doxygen#Doxygen Examples.. If multiple sections have the same title, add a number. #Example section 3 goes to the third section named "Example section".	You can link to a page section by its title: * [[Doxygen#Doxygen Examples]]. If multiple sections have the same title, add a number. [[#Example section 3]] goes to the third section named "Example section".
You can make a link point to a different place with a piped link. Put the link target first, then the pipe character "\|", then the link text. About Links Cities in Morocco Or you can use the "pipe trick" so that a title that contains disambiguation text will appear with more concise link text. Spinning Boston	You can make a link point to a different place with a [[Help:Piped link\|piped link]]. Put the link target first, then the pipe character "\|", then the link text. * [[Help:Link\|About Links]] * [[List of cities by country#Morocco\|Cities in Morocco]] Or you can use the "pipe trick" so that a title that contains disambiguation text will appear with more concise link text. * [[Spinning (textiles)\|]] * [[Boston, Massachusetts\|]]
You can make an external link just by typing a URL: http://www.nupedia.com You can give it a title: Nupedia Or leave the title blank: [1] External link can be used to link to a wiki page that cannot be linked to with [[page]]: http://meta.wikimedia.org/w/index.php?title=Fotonotes&oldid=482030#Installation	You can make an external link just by typing a URL: http://www.nupedia.com You can give it a title: [http://www.nupedia.com Nupedia] Or leave the title blank: [http://www.nupedia.com] External link can be used to link to a wiki page that cannot be linked to with <nowiki>[[page]]</nowiki>: http://meta.wikimedia.org/w/index.php?title=Fotonotes &oldid=482030#Installation
Linking to an e-mail address works the same way: mailto:someone@example.com or someone	Linking to an e-mail address works the same way: mailto:someone@example.com or [mailto:someone@example.com someone]
	#REDIRECT [[Official positions\|Official position]]
	[[Help:Category\|Category links]] do not show up in line but instead at page bottom ''and cause the page to be listed in the category.'' [[Category:English documentation]] Add an extra colon to ''link'' to a category in line without causing the page to be listed in the category: [[:Category:English documentation]]
	The Wiki reformats linked dates to match the reader's date preferences. These three dates will show up the same if you choose a format in your [[Special:Preferences\|]]: * [[1969-07-20]] * [[July 20]], [[1969]] * [[20 July]] [[1969]]

Just show what I typed

A few different kinds of formatting will tell the Wiki to display things as you typed them.

What it looks like

What you type

The nowiki tag ignores [[Wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: →

<nowiki>
The nowiki tag ignores 
[[Wiki]] ''markup''.
It reformats text by 
removing
newlines    and multiple
 spaces.
It still interprets special
characters: &rarr;
</nowiki>

The pre tag ignores [[Wiki]]
 ''markup''.
It also doesn't     reformat
 text.
It still interprets special
characters: →

<pre>
The pre tag ignores [[Wiki]]
 ''markup''.
It also doesn't     reformat
 text.
It still interprets special
characters: &rarr;
</pre>

Leading spaces are another way to preserve formatting.

Putting a space at the
beginning of each
line stops the text   
from being
reformatted.  It still 
interprets Wiki
markup and special
characters: →

Source code

Main article: mw:Extension:SyntaxHighlight

If the syntax highlighting extension is installed, you can display programming language source code in a manner very similar to the HTML <pre> tag, except with the type of syntax highlighting commonly found in advanced text editing software.

List of supported languages: http://pygments.org/languages/

Here's an example of how to display some C# source code:

<syntaxhighlight lang="csharp">
// Hello World in Microsoft C# ("C-Sharp").

using System;

class HelloWorld
{
    public static int Main(String[] args)
    {
        Console.WriteLine("Hello, World!");
        return 0;
    }
}
</syntaxhighlight>

Results in:

// Hello World in Microsoft C# ("C-Sharp").

using System;

class HelloWorld
{
    public static int Main(String[] args)
    {
        Console.WriteLine("Hello, World!");
        return 0;
    }
}

Images, tables, video, and sounds

This is a very quick introduction. For more information, see:

Help:Images and other uploaded files, for how to upload files;

w:en:Wikipedia:Extended image syntax, for how to arrange images on the page;

Help:Table, for how to create a table.

After uploading, just enter the filename, highlight it and press the "embedded image"-button of the edit_toolbar.

This will produce the syntax for uploading a file [[Image:filename.png]]

What it looks like

What you type

A picture, including alternate text:

You can put the image in a frame with a caption:

A picture, including alternate text:

[[Image:Wiki.png|This is Wiki's logo]]

You can put the image in a frame with a caption:
[[Image:Wiki.png|frame|This is Wiki's logo]]

A link to Wikipedia's page for the image: Image:Wiki.png

Or a link directly to the image itself: Media:Wiki.png

A link to Wikipedia's page for the image:
[[:Image:Wiki.png]]

Or a link directly to the image itself:
[[Media:Wiki.png]]
