Link Variables

admins (advanced)
$EnableLinkPageRelative
When enabled, causes Pm Wiki to use relative urls for page links instead of absolute urls.
        $EnableLinkPageRelative = 1;
$EnableLinkPlusTitlespaced
When enabled, a link written like [[Name|+]] will display the "Spaced Title". Default is to display the "Title" of the page. See the page PageVariables for {$Title} and {$Titlespaced}.
$PagePathFmt
This array lists the order in which Pm Wiki looks for the page that you most likely are attempting to link to. The default is listed below. Look at Cookbook:PagePaths for some ideas.
        array('{$Group}.$1', '$1.$1', '$1.{$DefaultName}')
$LinkPageExistsFmt
The (HTML) string to output for links to already existing wiki pages. Defaults to
        <a class='wikilink' href='\$LinkUrl'>\$LinkText</a>
$LinkPageCreateFmt
The (HTML) string to output for links to non-existent wiki pages. The default is to add a '?' after the link text with a link to the page edit/create form. Defaults to
        <a class='createlinktext' href='\$PageUrl?action=edit'>\$LinkText</a>
        <a class='createlink' href='\$PageUrl?action=edit'>?</a>
$LinkPageCreateSpaceFmt
Same as $LinkPageCreateFmt, but used when the link text has a space in it.
$LinkPageSelfFmt
The (HTML) string to output for self-referencing links (i.e. links to the page itself). Defaults to
        <a class='selflink' href='\$LinkUrl'>\$LinkText</a>
$UrlLinkFmt
The (HTML) string to output for URL-links that begin with 'http:', 'ftp:', etc. Defaults to
        <a class='urllink' href='\$LinkUrl' title='\$LinkAlt' rel='nofollow'>\$LinkText</a>
$IMapLinkFmt
an array of link formats for various link "schemes". Not set as default.
Examples of custom formats to allow different styling via classes:
Links to http: standard url links:
         $IMapLinkFmt['http:'] = "<a class='httplink urllink' href='\$LinkUrl'>\$LinkText</a>";  
Links to https: secure pages:
         $IMapLinkFmt['https:'] = "<a class='httpslink urllink' href='\$LinkUrl'>\$LinkText</a>";   
Links to Pm Wiki: Inter Map shortcut:
         $IMapLinkFmt['PmWiki:'] = "<a class='pmwikilink urllink' href='\$LinkUrl'>\$LinkText</a>";
$InterMapFiles
An array consisting a list of files and pages containing InterMap entries to be loaded.
$MakePageNameFunction
Name of a custom function to replace MakePageName(), which converts strings into valid page names.
$MakePageNamePatterns
$MakePageNamePatterns is an array of regular expression replacements that is used to map the page link in a free link such as [[free link]] into a page name. Currently the default sequence is:
    "/'/" => '',			   # strip single-quotes
    "/[^$PageNameChars]+/" => ' ',         # convert everything else to space
    '/((^|[^-\\w])\\w)/' => PCCF("return strtoupper(\$m[1]);"),
    '/ /' => ''
Note that if you change $MakePageNamePatterns, the documentation links may break. This can be fixed by re-setting $MakePageNamePatterns to the default in local/Pm Wiki.php.
$MakePageNameSplitPattern
See Cookbook:DotsInLinks.
$WikiWordCountMax
The maximum number of times to convert each Wiki Word encountered on a page. Defaults to 1,000,000. Common settings for this variable are zero (disable Wiki Word links) and one (convert only the first occurrence of each Wiki Word).
        $WikiWordCountMax = 0;     # disable Wiki Word links
        $WikiWordCountMax = 1;     # convert only first Wiki Word
$WikiWordCount
An array that allows the number of Wiki Word conversions to be set on a per-Wiki Word basis. The default is to use $WikiWordCountMax unless a value is set in this array. By default Pm Wiki sets $WikiWordCount['Pm Wiki']=1 to limit the number of conversions of "Pm Wiki".
        $WikiWordCount['PhD']=0;     # Don't convert "PhD"
        $WikiWordCount['Wiki Word']=5;  # Convert Wiki Word 5 times
        # the following lines keep a page from linking to itself
        $title = FmtPageName('$Title_',$pagename);
        $WikiWordCount[$title]=0;   
$EnableRedirectQuiet
Enable the quiet=1 parameter for the redirect directive. On publicly edited wikis it is advisable not to enable quiet redirects.
        $EnableRedirectQuiet = 0;     # disable quiet redirects (default)
        $EnableRedirectQuiet = 1;     # enable quiet redirects
