Introduction

This page is a quick reference for wikitext-code. A full help for Wiki markup can be found at Wikipedia.

WikiPages gives common guidelines on the best practices to be followed when writing FreeCAD documentation.

This Editing Overview has a lot of wikitext examples. You may want to keep this page open in a separate browser window for reference while you edit.

Editing basics

Start editing
To start editing a MediaWiki page, click the Edit link at the top of the page. This brings you to the Editing... page: a page with a text box containing the wikitext: the editable source code from which the server produces the webpage. If you just want to experiment, please do so in the sandbox, not here.
Type your changes
You can just type your text. However, also using basic wiki markup (described in the next section) and adding links adds to the value of your contribution.
Summarize your changes
Write a short edit summary in the small field below the edit-box. You may use shorthand to describe your changes, as described in the legend.
Upload images
You can also add images and screenshots. Please only upload *.png and *.svg files.
Preview before saving
When you have finished, click the Show preview button to see how your changes will look before making them permanent. Repeat the edit/preview process until you are satisfied, then click the Save page button. Your changes will be applied to the page immediately.

Basic text formatting

What you type What it looks like
You can ''italicize text'' by putting 2 apostrophes on each side. 

3 apostrophes will bold '''the text'''. 

5 apostrophes will bold and italicise '''''the text'''''.

4 apostrophes don't do anything special, there's just
''''one left over''''.

A single newline
has no effect
on the layout.

But an empty line
starts a new paragraph.

You can break lines<br>
without a new paragraph.<br>
Please use this sparingly.

You should sign your comments on talk pages:<br>
- Three tildes gives your user name: ~~~<br>
- Four tildes give your user name plus date/time: ~~~~<br>
- Five tildes gives the date/time only: ~~~~~<br>

You should sign your comments on talk pages:
- Three tildes gives your user name: Dr. Schorsch
- Four tildes give your user name plus date/time: Dr. Schorsch 20:55, 1 November 2006 (CET)
- Five tildes gives the date/time only: 21:01, 1 November 2006 (CET)

You can use <b>HTML tags</b>, too. For example:

Put text in a <tt>typewriter font</tt>. The same
font is generally used for <code>computer code</code>.

<strike>Strike out</strike> or <u>underline</u> text,
or write it in <span style="font-variant:small-caps">
small caps</span>.

Superscripts and subscripts:
X<sup>2</sup>, H<sub>2</sub>O

Invisible comments to editors (<!-- -->) 
only appear while editing the page.
<!-- Note to editors: blah blah blah. -->

If you wish to make comments to the public, 
you should go to the [[wikipedia:wikipedia:talk page|talk page]].

You can use HTML tags, too. For example:

Put text in a typewriter font. The same font is generally used for computer code.

Strike out or underline text, or write it in small caps.

Superscripts and subscripts: X2, H2O

Invisible comments to editors (<!-- -->) only appear while editing the page.

If you wish to make comments to the public, you should go to the talk page.

For a list of HTML tags that are allowed, see HTML in wikitext. However, you should avoid HTML in favor of wiki markup whenever possible.

Organizing your writing

What it looks like What you type
Section headings

Headings organize your writing into sections. The Wiki software can automatically generate a table of contents from them.

Subsection

Using more equals signs creates a subsection.

A smaller subsection

Don't skip levels, like from two to four equals signs.

Start with 2 equals signs not 1 because 1 creates H1 tags which should be reserved for page title.

External links

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

Here's a link to a page named Compile on Linux/Unix. You can not say compileonunix but Compile on Linux/Unixes and the link will show up correctly.

Here's a link to a page named [[Compile on Linux/Unix]].
You can not say [[compileonunix]] but
[[Compile on Linux/Unix]]es and the link will
show up correctly.

You can put formatting around a link. Example: Compile on Linux/Unix.

You can put formatting around a link.
Example: ''[[Compile on Linux/Unix]]''.

The first letter of articles is automatically capitalized, so Compile on Linux/Unix goes to the same place as compile on Linux/Unix. Capitalization matters after the first letter.

The ''first letter'' of articles is automatically
capitalized, so [[Compile on Linux/Unix]] goes to the same place
as [[compile on Linux/Unix]]. Capitalization matters after the
first letter.

The weather in Riga is a page that doesn't exist yet. You could create it by clicking on the link.

[[The weather in Riga]] 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 heading:

If multiple sections have the same heading, add a number. #Example section 3 goes to the third section named "Example section".

You can link to a page section by its heading:

*[[Help:Editing#Organizing your writing]].

If multiple sections have the same heading, 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.

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.

*[[Compile on Linux/Unix|Compile on Linux/Unix]]

You can make a link to Wikipedia by typing: wikipedia:Python (programming language)

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]

You can make a link to Wikipedia by typing:
[[wikipedia:Python (programming language)]]

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]

Linking to an e-mail address works the same way: mailto:someone@domain.com or someone

Linking to an e-mail address works the same way:
mailto:someone@domain.com or 
[mailto:someone@domain.com someone]

You can redirect the user to another page.

#REDIRECT [[Official position]]

To put an article in a category, place a link like Category:Help into the article. Category links do not show up in line but at page bottom and cause the page to be listed in the category.

To link to a category page without putting the article into the category, use a colon prefix (":Category") in the link. Category:Help

To put an article in a category, 
place a link like Category:Help into the article.
Category links do not show up in line
but at page bottom ''and cause the page to be''
''listed in the category.''
[[Category:Help]]

To link to a category page without putting the article
into the category, use a colon prefix (":Category")
in the link. [[:Category:Help]]

You can include pictures . You can refer to MediaWiki Images Help for details about the possible options. A very useful one is 'none', allowing your picture to be positioned on the left, with no flowing text:

You can include pictures [[Image:Base_ExampleCommandModel.png]].

You can use ordered or unordered lists:

  1. Item1
    1. Sub-item 1.1
      1. Sub-item 1.1.1
    2. Sub-item 1.2
  2. Item2
  • Item1
    • Sub-item 1.1
      • Sub-item 1.1.1
    • Sub-item 1.2
  • Item2
You can use ordered or unordered lists:

# Item1
## Sub-item 1.1
### Sub-item 1.1.1
## Sub-item 1.2
# Item2

* Item1
** Sub-item 1.1
*** Sub-item 1.1.1
** Sub-item 1.2

Code blocks and syntax highlighting

To mark a code block a number of solutions are available. The Code template is the preferred solution.

Prepend a space to each line

Example:

 import math
 from pivy import coin
 cam = Gui.ActiveDocument.ActiveView.getCameraNode()
 rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
        self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
        self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))

Result:

import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))

Use <pre> tags

Example:

<pre>
import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))
</pre>

Result:

import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))

Use <syntaxhighlight> tags

As the name implies, these tags will highlight the syntax. The lang parameter is required.

Example:

<syntaxhighlight lang="python">
import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))
</syntaxhighlight>

Result:

import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))

Use the Code template

The Code template will also highlight the syntax. If the language is Python the lang parameter is optional.

Example:

{{Code|lang=python|code=
import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))
}}

Result:

import math
from pivy import coin
cam = Gui.ActiveDocument.ActiveView.getCameraNode()
rot.setValue(coin.SbVec3f(0,0,1),math.pi/2)
       self.lineEdit_1 = QtGui.QLineEdit(self.centralWidget)
       self.lineEdit_1.setGeometry(QtCore.QRect(320, 30, 151, 22))

Templates and transcluding pages

Templates are segments of wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}. By default, pages are transcluded from the default Template namespace. The namespace is the portion of a page name before the colon; for instance, in Help:Editing, Help is the namespace in which the page Editing lives.

It is also possible to transclude other pages from the default namespace (the null one) by using {{:colon and double braces}}.

There are three pairs of transclusion markup tags that can be used in wikitext to control how transclusion affects parts of a template or article. They determine whether or not wikitext renders, either in its own article, which we will call "here", or in another article where it is transcluded, which we will call "there".

  • <noinclude>: the content will not be rendered there. These tags have no effect here.
  • <includeonly>: the content will render only there, and will not render here (like invisible ink made visible by means of transclusion).
  • <onlyinclude>: the content will render here and will render there, but it will only render there what is between these tags.

There can be several such section. Also, they can be nested.

Remark: if a page is transcluded without any transclusion markup, it may cause an unintentional categorization. Any page transcluding it will contain the same category as the original page. Wrap the category markup with <noinclude> tags to prevent incorrect categorization.

What it looks like What you type

This text comes from the page named Template:Transclusion demo. It has been transcluded into this page.

{{Transclusion demo}}

This transclusion demo is a little bit of text from the page Help:Transclusion demo to be included into any file.

{{Help:Transclusion demo}}

Special Pages

Special pages are pages that cannot be edited, but are generated by the wiki engine. They provide very useful functions, and live in the Special namespace. A summary of all special pages is available from Special:SpecialPages.

Direct link to frequently used Special pages are:

Minor edits

A logged-in user can mark an edit as "minor". Minor edits are generally spelling corrections, formatting, and minor rearrangement of text. Users may choose to hide minor edits when viewing Recent Changes.

Marking a significant change as a minor edit is considered bad Wikiquette. If you have accidentally marked an edit as minor, make a dummy edit, verify that the "[ ] This is a minor edit" check-box is unchecked, and explain in the edit summary that the previous edit was not minor.
