Mediawiki formatting

This is a partial copy of How to edit a page of Wikipedia. Here you can see what works and what doesn't work.

Wiki markup


{{shortcut|WP:MARKUP}}

The wiki markup is the syntax system you can use to format a Wikipedia page; please see Editing for details on it, and Wikitext examples for a longer list of the possibilities of Wikitext.

Links and URLs


What it looks like What you type
London has public transport.
  • A link to another Wiki article.
  • Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
  • Thus the link above is to the URL en.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Canonicalization.
<nowiki>
London has [[public transport]].
</nowiki>
San Francisco also has public transportation.
  • Same target, different name.
  • The target ("piped") text must be placed first, then the text that will be displayed second.
<nowiki>
San Francisco also has
[[public transport| public transportation]].
</nowiki>
San Francisco also has

public transportation.

Examples include buses, taxicabs,
and streetcars.

  • Endings are blended into the link.
  • Preferred style is to use this instead of a piped link, if possible.
  • Blending can be suppressed by using <nowiki></nowiki> tags, which may be desirable in some instances. Example: a microsecond.
<nowiki>
San Francisco also has
[[public transport]]ation.

Examples include [[bus]]es,
 [[taxicab]]s, and [[streetcar]]s.

a [[micro]]<nowiki>second</nowiki>
</nowiki>
See the Manual of Style.
  • A link to another namespace.
<nowiki>
See the 
[[Wikipedia:Manual of Style]].
</nowiki>
Automatically hide stuff in parentheses:

kingdom.

Automatically hide namespace:
Village Pump.

Or both:
Manual of Style

But not:
Manual of Style#Links

  • The server fills in the part after the pipe character (|) when you save the page. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page (see previous entry#link-to-section).
  • See Pipe trick for details.
<nowiki>
Automatically hide stuff
in parentheses:
[[kingdom (biology)|]].

Automatically hide namespace:

<!-- A village pump proposal was made so that users would be allowed to create the article shown here. Pages here would be articles requested for a long time. If you find someone has created the article, please look in requested articles and put one in its place -->

National sarcasm society is a page
that does not exist yet.

  • You can create it by clicking on the link.
  • To create a new page:
    1. Create a link to it on some other (related) page.
    2. Save that page.
    3. Click on the link you just made. The new page will open for editing.
  • For more information, see How to start a page and check out Wikipedia's naming conventions.
  • Please do not create a new article without linking to it from at least one other article.
<nowiki>
[[National sarcasm society]]
is a page 
that does not exist yet.
</nowiki>
How to edit a page is a link to this page.
  • Self links appear as bold text when the article is viewed.
  • Do not use this technique to make the article name bold in the first paragraph; see the Manual of Style.

The character tilde (~) is used when adding a comment to a Talk page.

You should sign your comment by appending four tildes (~~~~)
to the comment so as to add your user name plus date/time:

Patricia Zhang 13:40, Jan 14, 2007 (UTC)

Adding three tildes (~~~) will add just your user name:

Patricia Zhang

and adding five tildes (~~~~~) gives the date/time alone:

13:40, Jan 14, 2007 (UTC)

  • The first two both provide a link to your user page.
<nowiki>
The character '''tilde''' (~) is used 
when adding a comment to a Talk page. 
You should sign your comment by 
appending four tildes (~~~~)
to the comment so as to add your 
user name plus date/time:

* Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").
  • It is possible to redirect to a section. For example, a redirect to United States History#History will redirect to the United States page, to the History section if it exists.
  • <nowiki>
    #REDIRECT [[United States]]
    
    #REDIRECT [[United States#History|United 
    States History]] will redirect to the 
    [[United States]] page, to the History 
    section if it exists 
    </nowiki>
    * Link to a page on the same subject in another language by placing a link of the form: [[language code:Title]] in the wiki text of the article.

    For example in the article on Plankton, which is available on a lot of other wikis, the interlanguage links would look like so:

    [[de:Plankton]] [[es:Plancton]] [[ru:Планктон]] [[simple:Plankton]]

    • While it does not matter where you put these links while editing, it is recommended that these links be placed at the very end of the edit box.
    • These will not be visible in the main text of the article on which they are placed but appear as links in the extreme left margin column of Wikipedia page as part of a separate box under the 'toolbox' titled 'in other languages'. You can check out the links to the corresponding page in wikipedias of other languages for this Wikipedia MOS help page itself.
    • Please see Interlanguage links and the list of languages and codes.

    • Link to books using their ISBN. This is preferred to linking to a specific online bookstore, because it gives the reader a choice of vendors. However, if one bookstore or online service provides additional free information, such as table of contents or excerpts from the text, then a link to that source will aid the user and is recommended.
    • ISBN links do not need any extra markup, provided you use one of the indicated formats.

    Headings

    For a top-level heading, put it on a separate line surrounded by '=='. For example:

    ==Introduction==

    Subheadings use '===', '====', and so on.

    A typewriter font for monospace text
    or for computer code:

    Use <code><pre> Block of Code </pre></code> 
    around the block of code.
    
    * The <pre> tags within the code block 
    will create formatting issues. To solve, 
    display the tags literally with

    You can <s>strike out deleted material</s>
    and underline new material.

    You can also mark <del>deleted material</del> and
    <ins>inserted material</ins> using logical markup.
    For backwards compatibility better combine this
    potentially ignored new <del>logical</del> with
    the old <s><del>physical</del></s> markup.

    • When editing regular Wikipedia articles, just make your changes and do not mark them up in any special way.
    • When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted material.
    <nowiki>
    You can <s>strike out deleted material</s>
    and <u>underline new material</u>.
    
    You can also mark <del>deleted material</del> and

    Suppressing interpretation of markup:



    Link → (''to'') the [[Wikipedia FAQ]]

    • Used to show literal data that would otherwise have special meaning.
    • Escape all wiki markup, including that which looks like HTML tags.
    • Does not escape HTML character references.
    • To escape HTML character references such as &rarr; use &amp;rarr;

For the 1-2-3 superscripts, it is nevertheless preferred when possible (as with units of measurement) because most browsers have an easier time formatting lines with it.

    Ordinary text should use wiki markup for emphasis#emph, and should not use

    224i225
    or
    226b227
    . However, mathematical formulae often use italics, and sometimes use bold, for reasons unrelated to emphasis. Complex formulae should use 317 markup, and simple formulae may use
    230math231
    ; or
    232i233
    and
    234b235
    ; or
    <nowiki>''</nowiki>

    </nowiki>
    Spacing in simple math formulae:


    Obviously, x² ≥ 0 is true when x is a real number.
    • To space things out without allowing line breaks to interrupt the formula, use non-breaking spaces: &nbsp;.

    <nowiki>
    Obviously, ''x''&sup2;&nbsp;&ge;&nbsp;0 is true 
    when ''x'' is a real number.
    </nowiki>
    Complicated formulae:


    <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>

    • See Formula for how to use <math>.
    • A formula displayed on a line by itself should probably be indented by using the colon (:) character.

    <nowiki>
    : <math>\sum_{n=0}^\infty \frac{x^n}{n!}</math>
    </nowiki>

    (see also: Chess symbols in Unicode)

    No or limited formatting—showing exactly what is being typed

    A few different kinds of formatting will tell the Wiki to display things as you typed them—what you see, is what you get!

    What it looks like What you type
    <nowiki> tag:

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

    </nowiki>
    <pre> tag:

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

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

    Leading spaces are another way
    to preserve formatting. However, it will make the whole page fail to render properly in some browsers, such as IE7, thus making the page unreadable.

    Putting a space at the beginning of each line
    stops the text from being reformatted.
