(:Summary:variables that control the display of links in pages:)
(:Audience: admins (advanced):)
:$EnableLinkPageRelative:When enabled, causes PmWiki to use relative urls for page links instead of absolute urls.
        $EnableLinkPageRelative = 1;

:$PagePathFmt: This array lists the order in which PmWiki looks for the page that you ''most likely'' are attempting to link to. The default is listed below. Look at Cookbook:PagePaths for some ideas.
        [=array('{$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 PmWiki: InterMap 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 (see [[CustomInterMap]]).

:$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 non-alnums to spaces
    "/((^|[^-\\w])\\w)/e" 
      => "strtoupper('$1')",               # initial caps after spaces
    "/ /" => ''                            # strip spaces
@]
: :Note that if you change $MakePageNamePatterns, the documentation links may break. This can be fixed by re-setting $MakePageNamePatterns to the default in local/PmWiki.php.

:$WikiWordCountMax:The maximum number of times to convert each WikiWord encountered on a page.  Defaults to 1,000,000.  Common settings for this variable are zero (disable WikiWord links) and one (convert only the first occurrence of each WikiWord).
        $WikiWordCountMax = 0;     # disable WikiWord links
        $WikiWordCountMax = 1;     # convert only first WikiWord

:$WikiWordCount:An array that allows the number of WikiWord conversions to be set on a per-WikiWord basis.  The default is to use $WikiWordCountMax unless a value is set in this array.  By default PmWiki sets @@$WikiWordCount['PmWiki']=1@@ to limit the number of conversions of "PmWiki".
        $WikiWordCount[=['PhD']=0;     # Don't convert "PhD"=]
        $WikiWordCount['WikiWord']=5;  # Convert WikiWord 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 [[PmWiki.PageDirectives#redirect|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
