WikiLinks provide easy linking between pages of the wiki. To create a
[[WikiLink]], just put the name of the page to link to in double brackets.
For example `\[[WikiLink]]`.
If you ever need to write something like `\[[WikiLink]]` without creating a
wikilink, just prefix it with a `\`, like `\\[[WikiLink]]`.
There are some special [[SubPage/LinkingRules]] that come into play when
linking between [[SubPages|SubPage]].
Also, if the file linked to by a WikiLink looks like an image, it will
be displayed inline on the page.
WikiLinks are matched with page names in a case-insensitive manner, so you
don't need to worry about getting the case the same, and can capitalise
links at the start of a sentence, and so on.
It's also possible to write a WikiLink that uses something other than the page
name as the link text. For example `\[[foo_bar|SandBox]]` links to the SandBox
page, but the link will appear like this: [[foo_bar|SandBox]].
To link to an anchor inside a page, you can use something like
`\[[WikiLink#foo]]`
## Preprocessor directives and wikilinks
ikiwiki has two syntaxes for
[[preprocessor_directives|PreprocessorDirective]]. The older syntax
used spaces to distinguish between preprocessor directives and
wikilinks; as a result, with that syntax in use, you cannot use spaces
in WikiLinks, and must replace spaces with underscores. The newer
syntax, enabled with the `prefix_directives` option in an ikiwiki
setup file, prefixes directives with `!`, and thus does not prevent
links with spaces. Future versions of ikiwiki will turn this option
on by default.
