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.

1 Hyperlinks

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.

1.1 Links to sections and subsections

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

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

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

1.2 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

[http://www.him.uni-bonn.de/kreck homepage]

produces the link homepage.

2 Comments

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

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

3 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.

4 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 ==
<wikitex>; 
TEXT
</wikitex>

===<subsectioncount/> Seiberg-Witten invariants ===
<wikitex>;
MORE TEXT
</wikitex>

</wikitex>

5 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 mind 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.
