Manifold Atlas:Wiki syntax

This page collects some simple but useful tips about the Wiki syntax. The MediaWiki Handbook is a good reference for the wiki software: see especially the section for editors.



You create hyperlinks inside the Manifold Atlas by writing [[page name|link text]]. For example

[[Surfaces|2-dimensional manifold]]

produces the link 2-dimensional manifold.

If you wish to link to a Wikipedia page, use the above format with the page name: Wikipedia:page_name. For example

[[Wikipedia:Differentiable_manifold|smooth manifold]]

produces the link smooth manifold.

Links to sections and subsections

You can refine your hyperlinks to sections and even subsections of web-pages. For example

[[5-manifolds: 1-connected#Invariants|linking form]]

produces the link linking form, which goes directly to the invariants section of the page on simply-connected 5-manifolds.

External links

For a general web address, insert the entire URL in the address field and seperate the link text simply with a space. For example

[ homepage]

produces the link homepage.

Open and broken links

If the address part of a link is empty or incorrect you will produce an open or broken hyper link

Writing open links can be helpful.

  • It can speeding up writing (come back and fill address later).
  • It can indicate pages you would like to see created in the future in the Atlas:
    • if you click an open link the Wiki system creates the edit-page for page named by the address in the open link.


You can comment out text simply by placing it within <!-- ... -->. For example:

<!-- This text would not appear on the page. -->

Bold face and emphasis

To obtain bold face, place text or links inside three single quotation marks: ''' ... '''. For example

'''bold text''' and a [[Hirzebruch surfaces|'''bold link''']]

produces bold text and a bold link.

You can also emphasise text in a similar way by placing it with in two single quotation marks.

Sections, subsections, etc

  • Sections, subsections and subsubsections etc are produced using == ... ==, === ... === and ==== ... ==== etc.
  • Make sure that text between section headers is enclosed with the tags <wikitex> ... </wikitex>.
  • For example:
==<sectioncount/> Invariants ==

===<subsectioncount/> Seiberg-Witten invariants ===

Line breaks

The Wiki syntax is very sensitive to spare line-breaks in contrast to LaTeX which many authors may be used to. You may find that new sections and subsections appear with large spaces either at their beginning or end: if so you will need to hunt down the spare lines causing them and delete them.
