Link Variables

$EnableLinkPageRelative

When enabled, causes PmWiki to use relative urls for page links instead of absolute urls.

$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 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.

$LinkPageExistsFmt

The (HTML) string to output for links to already existing wiki pages. Defaults to

$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

$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

$LinkCategoryFmt

The (HTML) string to output for links to wiki category pages. Defaults to

$UrlLinkFmt

The (HTML) string to output for URL-links that begin with 'http:', 'ftp:', etc. Defaults to

$IMapLinkFmt

an array of link formats for various link "schemes". Not set as default.

$AddLinkCSS

An array of additional custom link CSS classes, that are added to the link format $UrlLinkFmt, $IMapLinkFmt or $LinkPageExistsFmt. Currently can have 2 elements:
$AddLinkCSS['othergroup'] = "crossgroup"; # add "crossgroup" class to wikilinks to other wikigroups
$AddLinkCSS['samedomain'] = "currentsite"; # add "currentsite" class to URL or Path links to resources on the same domain.

$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 to spaces characters not allowed in pagenames
    '/((^|[^-\\w])\\w)/' => 'cb_toupper',  # capitalize 1st letter of words
    '/ /' => ''                     # remove 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.

$MakePageNameSplitPattern

See Cookbook:DotsInLinks.

$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).

$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 redirect directive. On publicly edited wikis it is advisable not to enable quiet redirects.

$QualifyPatterns

An array of regular expression replacements applied when text from one page is included in another, used by the function Qualify(). The two default patterns rewrite links like [[Page]] into [[Group/Page]], and page (text) variables like {$Title} into {Group.Page$Title} so that they work the same way in the source page and in the including page.
