VLBI Wiki | PmWiki / Links

authors (basic) A key feature of WikiWikiWebs is the ease of creating links in the text of a document. PmWiki provides multiple mechanisms for creating such links.

Links to other pages

To create a link to another page, simply enclose the name of the page inside double square brackets, as in [[wiki sandbox]] or [[installation]]. These result in links to wiki sandbox and installation, respectively.

PmWiki creates a link by using the text inside the double brackets. It does this by removing spaces between words, and automatically capitalizing words following spaces or other punctuation (like ~). Thus [[Wiki sandbox]], [[wiki sandbox]], and [[WikiSandbox]] all display differently but create the same link to the page titled WikiSandbox.

In other words, PmWiki will automatically create the link path name using title case as a rule, but link text will display in the format you have entered it.

A suffix can also be added to the end of a link, which becomes part of the link text but not the target. Thus [[wiki sandbox]]es is a link to WikiSandbox but displays as wiki sandboxes.

Link text in (parentheses) will not be not displayed, so that [[(wiki) sandbox]] links to WikiSandbox and displays as sandbox.

Finally, you can specify the link text via a vertical brace, thus [[WikiSandbox | a play area]], which links to WikiSandbox but displays as a play area. You can use an arrow (->) to reverse the order of the text and target, as in [[a play area -> WikiSandbox]] (a play area).

Some sites also recognize WikiWord links, in which a WikiWord appearing in the text is automatically treated as a link to a page of the same name.

Link Shortcuts

[[PageName|+]] creates a link to PageName and uses that page's title as the link text, eg [[Links|+]] gives Links.

[[PageName|#]] creates a reference link as shown below.

[[!PageName]]creates a link to the PageName in the group called Category.

[[~Author]] link creates a link to the page in the page called Author in the Profiles group. PmWiki will automatically generate that link for the current Author when it encounters three tilde characters (~) in a row (~~~). Adding a fourth tilde (~~~~) appends the current date and time.

Links to specific locations within a page

To define a location within a page to which you may jump directly, use the markup [[#name]]. This creates an "anchor" that uniquely identifies that location in the page. Then to have a link jump directly to that anchor, use one of

[[#name|link text]] within the same page, or
[[PageName#name]] or [[PageName#name|link text]] for a location on another page
The form [[PageName(#name)]] may be useful for hiding the anchor text in a link.

For example, here's a link to the Intermaps section, below.

Links to external sites (URLs)

Links to external sites simply begin with a prefix such as 'http:', 'ftp:', etc. Thus http://google.com/ and [[http://google.com/]] both link to Google. As with the above, an author can specify the link text by using the vertical brace or arrow syntax, as in [[http://google.com/ | Google]] and [[Google -> http://google.com]].

Links as References

Links may also be specifed as References, so the target appears as an anonymous numeric reference rather than a textual reference. The following markup is provided to produce sequential reference numbering within a PmWiki page:

Formatting the link as: [[http://google.com |#]] produces: [1] as the link.

Subsequent occurrence of the reference link format on the same page will be incremented automatically as per the following example: Entering [[http://pmwiki.com |#]] produces [2], [[#intermaps |#]] produces [3], and so on for further reference links.

Intermaps

InterMap links are also supported (see InterMap). In particular, the Path: InterMap entry can be used to create links using relative or absolute paths on the current site (e.g., Path:../../somedir/foo.html or Path:/dir/something.gif).

Links to pages in other wiki groups

See WikiGroup.

Links that open a new browser window

To have a link open in another window, use %newwin%:

%newwin% http://www.pmichaud.com produces http://www.pmichaud.com
%newwin% [[http://google.com/ | Google]] produces Google
%newwin% Main.WikiSandbox produces Main.WikiSandbox

You can also specify that links should open in a new window via the target attribute:

%target=_blank% Any links on this line like http://www.pmichaud.com 
will open in a new window.

Any links on this line like http://www.pmichaud.com will open in a new window.

How do I put a link that will open as a new window?

Use the %newwin% wikistyle, as in:

%newwin%http://www.example.com/

http://www.example.com/

How do I place a mailing address in a page?

Use the mailto: markup, as in one of the following:

    mailto:myaddress@example.com
    [[mailto:myaddress@example.com]]
    [[mailto:myaddress@example.com | email me]]

See also Cookbook:EProtect for information on protecting email addresses from spammers.

How do I make a WikiWord link to an external page instead of a WikiPage?

Use link markup. There are two formats:

    [[http://www.example.com/ | WikiWord]]
    [[WikiWord -> http://www.example.com/]]

How do I find all of the pages that link to another page (i.e., backlinks)?

Use the link= option of the (:pagelist:) directive, as in

    (:pagelist link=SomePage:)   -- show all links to SomePage
    (:pagelist link={$FullName}:)  -- show all links to the current page
