Variable substitutions in the skin template are all managed by the FmtPageName() function from pmwiki.php. Pmwiki variable substitutions available on pages are managed by the substitutions from stdmarkup.php or superseded in local/config files.

%apply=item id=ActionSkin ?%$ActionSkin

This array is used to override the current skin when performing a given action. The most common use is to set $ActionSkin['print']='foo' to use the 'foo' skin when printing, regardless of what the $Skin variable is set to.

%apply=item id=WikiTitle ?%$WikiTitle

A variable which contains the Wiki title as displayed in the browser tab and at the top of the browser window.

%apply=item id=EnablePageTitlePriority ?%$EnablePageTitlePriority

A variable defining how to treat multiple (:title ...:) page directives (added in PmWiki 2.2.9).

$EnablePageTitlePriority = 0; # PmWiki default, last encountered title wins (the title may be changed from included pages or GroupFooter).

$EnablePageTitlePriority = 1; # First title wins; if a title is defined in the page, directives from included pages cannot change it.

%apply=item id=EnableDiffInline ?%$EnableDiffInline

If set to 0, this variable switches off the word-level highlighting on the markup in the page history.

$EnableDiffInline = 0; # Disable colors, show plain text differences

%apply=item id=EnableRCDiffBytes ?%$EnableRCDiffBytes

If set to 1, (All)RecentChanges ? pages will display the difference in bytes of the page content from the previous version like (+123) or ~~(-42)~~

$EnableRCDiffBytes = 1; # Show bytes difference from previous version

The colors are the same as those in the page history; if your skin doesn't provide them, add to pub/css/local.css something like:

.diffmarkup { font-family: monospace; font-size: 0.9em; } 
.diffmarkup del { background: #ff9; text-decoration: none; }
.diffmarkup ins { background: #9f9; text-decoration: none; }

%apply=item id=EnableHighlight ?%$EnableHighlight

If set to 1, enables compatibility with the highlight.js library to highlight program code. In addition, you need to include the library and mark your code blocks with the wikistyle %highlight%, see WikiStyles#highlight.

%apply=item id=HTMLTagAttr ?%$HTMLTagAttr

A string containing attributes of the <html...> tag in the skin template, default empty. For example, to add a "lang" attribute, set in config.php:

$HTMLTagAttr = 'lang="en" xml:lang="en"';

For this variable to work in a custom skin, add it in the template file, for example:

<html xmlns="http://www.w3.org/1999/xhtml" $HTMLTagAttr>

%apply=item id=HTMLStylesFmt ?%$HTMLStylesFmt

An array of CSS statements to be included in the page's output along with other HTML headers. This array provides an easy place for scripts to add custom CSS statements.

%apply=item id=HTMLHeaderFmt ?%$HTMLHeaderFmt

An array of HTML text to be included in the page's <head> section, at the point where the skin template specifies a  directive. This array provides an easy place for scripts to add custom HTML headers.

For example, if you want to specify a logo for all the pages of your wiki (a png image for Firefox (and others...), an ico for Internet Explorer):

 
$HTMLHeaderFmt['logo'] =
  '<link href="http://path/to/logo.png" type="image/png" rel="icon" />
  <link href="http://path/to/logo.ico" type="image/x-icon" rel="shortcut icon" />';

Another example, if you want to get the RSS notification on some browsers (the RSS icon in Firefox for instance):

 
$HTMLHeaderFmt['rss'] =
  '<link rel="alternate" type="application/rss+xml" title="Rss All recent Changes" 
     href="$ScriptUrl/Site/AllRecentChanges?action=rss" />';

%apply=item id=HTMLFooterFmt ?%$HTMLFooterFmt: Like $HTMLHeaderFmt above, this contains an array of HTML text to be included near the end of an HTML document, at the point where the skin template specifies a  directive (usually just before a closing </body> tag). Primarily used by scripts to add custom HTML output after the body of the page output.
%apply=item id=MetaRobots ?%$MetaRobots: Sets the value of the <meta name='robots' ... /> tag generated by PmWiki to control search engine robots accessing the site. PmWiki's default setting tells robots to not index anything but the normal page view, and to not index pages in the PmWiki wiki group. Explicitly setting $MetaRobots overrides this default.

        # never index this site
        $MetaRobots = 'noindex,nofollow';
        # disable the robots tag entirely
        $MetaRobots = '';

%apply=item id=MessagesFmt ?%$MessagesFmt: An array of HTML text to be displayed at the point of any (:messages:) markup. Commonly used for displaying messages with respect to editing pages.
%apply=item id=RecentChangesFmt ?%$RecentChangesFmt: An array specifying the format of the RecentChanges ? listing.

The key of the array specifies the page where changes will be logged, as in

$RecentChangesFmt['$SiteGroup.AllRecentChanges']

The value of the array specifies the format in which the changes will be logged, as in

'* [[{$Group}.{$Name}]]  . . . $CurrentTime $[by] $AuthorLink: [=$ChangeSummary=]'

Note the two consecutive spaces before the three dots (. . .). The two spaces separate two parts of the format: the first part doesn't change (e.g. a link to the changed page) and the second part does change (e.g. the date and author of the change). Upon saving a page, PmWiki removes a line that matches the first part and adds a line with the current format before the first line with 2 spaces. This way, any line without two consecutive spaces stays at the top of the recent changes page.

You can use and adapt the following to change the format (put it in config.php):

$RecentChangesFmt['$SiteGroup.AllRecentChanges'] = 
  '* [[{$Group}.{$Name}]]  . . . $CurrentTime $[by] $AuthorLink: [=$ChangeSummary=]';
$RecentChangesFmt['$Group.RecentChanges'] =
  '* [[{$Group}/{$Name}]]  . . . $CurrentTime $[by] $AuthorLink: [=$ChangeSummary=]';

Note that changes made to the format will only affect new edits. In other words, you will need to edit a page for your new format to be visible. Note also that you need to have two spaces between the page name and the other information about the edit.

Also note that this variable has other uses, such as not reporting at all to RecentChanges ? and AllRecentChanges ? as found here PmWiki Questions.

%apply=item id=RecentUploadsFmt ?%$RecentUploadsFmt: An array specifying the format for uploaded files at the RecentChanges ? listing. It is similar to $RecentChangesFmt. If enabled, newly uploaded files will be logged to the RecentChanges ? pages. Default is disabled. See Cookbook:RecentUploadsLog for more information.
%apply=item id=DraftRecentChangesFmt ?%$DraftRecentChangesFmt: An array specifying the format of the RecentChanges ? listing when saving Draft pages.

$RecentChangesFmt is set to $DraftRecentChangesFmt when a Draft page is saved. For example, you could save drafts in a separate Recent Draft Changes page and not list in the normal group's Recent Changes page:

$DraftRecentChangesFmt['$Group.RecentDraftChanges'] =
  '* [[{$Group}/{$Name}]]  . . . $CurrentTime $[by] $AuthorLink: [=$ChangeSummary=]';
$DraftRecentChangesFmt['$Group.RecentChanges'] = '';

%apply=item id=RCLinesMax ?%$RCLinesMax: The maximum number of lines to be stored in RecentChanges ? pages. The default is zero, meaning "no limit".

        $RCLinesMax = 1000;       # maintain at most 1000 recent changes

%apply=item id=PageRedirectFmt ?%$PageRedirectFmt

The text to be used when a page is redirected via the (:redirect:) markup.

$PageRedirectFmt = '<p><i>redirected from $FullName</p>';
$PageRedirectFmt = '';

For display options, see also the FAQ on PageDirectives.

%apply=item id=WikiStyle ?%$WikiStyle: An array which contains the predefined WikiStyles which can be used on a textpage.
See: PmWiki.CustomWikiStyles
%apply=item id=WikiStyleApply ?%$WikiStyleApply: An array which defines the scope of wiki styling per HTML element. Default settings are:

'item' => 'li|dt',
'list' => 'ul|ol|dl',
'div' => 'div',
'pre' => 'pre',
'img' => 'img',
'block' => 'p(?!\\sclass=)|div|ul|ol|dl|li|dt|pre|h[1-6]',
'p' => 'p(?!\\sclass=)'

This defines that we can apply wiki styling on:

LI elements using the item keyword
UL, OL, DL elements using the list keyword
etc.

An example of applying scope to an LI element is below. For more information refer to WikiStyle scope.

* %apply=item red%Here is a red styled list item
* This item would not be styled.

Here is a red styled list item
This item would not be styled.

You can add additional HTML elements to $WikiStyleApply to apply wiki styles to other HTML elements. For example to allow styling on table rows, or anchor tags.

%apply=item id=WikiPageCSSFmt ?%$WikiPageCSSFmt: This variable holds a page name where you can add CSS rules applied to specific page patterns (default disabled). See Cookbook:LocalCSS as an example.
: $WikiPageCSSFmt = 'Site.LocalCSS?'; # global Site.LocalCSS ? page
: $WikiPageCSSFmt = '{$Group}.LocalCSS?'; # per-group LocalCSS ? pages
%apply=item id=WikiPageCSSVars ?%$WikiPageCSSVars: If a "wiki CSS page" is enabled with $WikiPageCSSFmt, this is an array with global PHP $variables available as pre-processor @variables in that page. By default the array contains: 'FarmPubDirUrl?', 'PubDirUrl?', 'Skin', 'action', 'SkinDirUrl?'.
%apply=item id=EnableSelfWikiPageCSS ?%$EnableSelfWikiPageCSS: If a "wiki CSS page" is enabled with $WikiPageCSSFmt, that specific page doesn't have CSS applied to itself when browsed or edited. In case a grave mistake is made in the styles and the site becomes unusable, this page will still be viewable and editable. People familiar with CSS can set this to 1 and the styles will be applied to the page itself, also in "Preview" mode:
: $EnableSelfWikiPageCSS = 1; # Apply styles to the "wiki CSS page" itself
%apply=item id=PmTOC ?%$PmTOC: Enable and configure the built-in table of contents, see Table of contents (TOC).
: $PmTOC['Enable'] = 1; # Enable TOC; default is 0 (disabled).
%apply=item id=ToggleNextSelector ?%$ToggleNextSelector: A CSS selector to enable interactive toggling of hidden sections, see Cookbook:ToggleNext. By default it is disabled.
%apply=item id=MaxIncludes ?%$MaxIncludes: Controls the number of times that pages can be included via the (:include:) and other directives, used to control recursion and otherwise pose a sanity check on page contents. $MaxIncludes defaults to 50, but can be set to any value by the wiki administrator.

        $MaxIncludes = 50;            # default
        $MaxIncludes = 1000;          # allow lots of includes
        $MaxIncludes = 0;             # turn off includes

$Skin: Lists the name(s) of skins to load, unless overridden by $ActionSkin. Normally $Skin contains a single string which is the name of a skin directory, but it may also be an array of names, in which case the first skin found from the list is used.
%apply=item id=SkinDirUrl ?%$SkinDirUrl: Set by scripts/skins.php to be the base url of the current skin's directory (i.e., within a 'pub/skins/' directory). This variable is typically used inside of a skin .tmpl file to provide access to .css files and graphic images associated with the skin.
%apply=item id=SkinLibDirs ?%$SkinLibDirs: An array which, given the filesystem path (array key) to a skin (or a directory containing several skins), provides the corresponding URL (array value).

The array key is the directory containing the skin.tmpl and skin.php files, as seen by the PmWiki program. It does not have to be publicly accessible.

The value is the URL (web address) of the directory containing the .css, .gif, and other files which appear in the HTML code sent by PMWiki ? to the browser. This directory must be publicly accessible.

By default $SkinLibDirs is set to:

$SkinLibDirs = array(
  "./pub/skins/\$Skin" => "$PubDirUrl/skins/\$Skin",
  "$FarmD/pub/skins/\$Skin" => "$FarmPubDirUrl/skins/\$Skin");

Extra details: When PMWiki ? is searching for a skin it looks for a directory named for the skin in the array index/keys, and if it finds it then it will use the files in that directory and also the files in the matching array value url. The two sides normally point to the same publicly accessible directory, but they do not have to.

%apply=item id=SkinTemplateIncludeLevel ?%$SkinTemplateIncludeLevel

how many levels of inclusion are allowed for skin templates with the  directive. By default this directive is disabled. Setting it to 1 allows one level of inclusions, setting it to 2 allows included templates to include more templates. There can be up to 10 levels of inclusion. This variable can be defined either in local/config.php or in pub/skins/skinname/skinname.php (with SDV):

  # in config.php, allow one level of inclusions
  $SkinTemplateIncludeLevel = 1; 

  # in skinname.php, allow 3 levels of inclusions
  SDV($GLOBALS['SkinTemplateIncludeLevel'], 3);

%apply=item id=PageLogoUrl ?%$PageLogoUrl

is the url that refers to a logo image which most skins display somewhere in the page's header (top left usually).

%apply=item id=EnablePathInfo ?%$EnablePathInfo

Changes the handling of the page URL. When set to 1 page URL will be ...wiki.php/Main/Main, when set to 0 (default) it will be ...wiki.php?n=Main.Main.

%apply=item id=EnableFixedUrlRedirect ?%$EnableFixedUrlRedirect

When PmWiki is given a partial page name (e.g., just the name of a WikiGroup), it uses $PagePathFmt in order to make a complete page name from the partial one, then issues a "redirect" to the browser to tell it to reload the page with the correct full page name. Setting $EnableFixedUrlRedirect=0; blocks the redirect, so that PmWiki continues processing with the adjusted page name rather than issuing the redirect.

%apply=item id=GroupHeaderFmt ?%$GroupHeaderFmt

Defines the markup placed at the top of every page. Default value is:

        $GroupHeaderFmt = '(:include {$Group}.GroupHeader self=0 basepage={*$FullName}:)(:nl:)';

%apply=item id=GroupPrintHeaderFmt ?%$GroupPrintHeaderFmt: Defines the markup placed at the top of every page when action=print. Default value is:

        SDV($GroupPrintHeaderFmt,'(:include $Group.GroupPrintHeader basepage={*$FullName}:)(:nl:)');

%apply=item id=GroupFooterFmt ?%$GroupFooterFmt: Defines the markup placed at the bottom of every page. Default value is:

        $GroupFooterFmt = '(:nl:)(:include {$Group}.GroupFooter self=0 basepage={*$FullName}:)';

%apply=item id=GroupPrintFooterFmt ?%$GroupPrintFooterFmt: Defines the markup placed at the bottom of every page when action=print. Default value is:

        SDV($GroupPrintFooterFmt,'(:nl:)(:include $Group.GroupPrintFooter basepage={*$FullName}:)');

%apply=item id=PageNotFoundHeaderFmt ?%$PageNotFoundHeaderFmt

Specifies the HTTP header to send when attempting to browse a page that doesn't exist. Some webserver packages (notably Microsoft's "Personal Web Server") require that this variable be changed in order to work.

# default
$PageNotFoundHeaderFmt = 'HTTP/1.1 404 Not Found';
# return all pages as found
$PageNotFoundHeaderFmt = 'HTTP/1.1 200 Ok';

Beware when expecting to return the content of a Group(header|footer) for an non existent page! By default PmWiki returns 404 (because the page does not exist), despite there is some content to show. Firefox shows the content, while Internet Explorer displays its default 404 page. $PageNotFoundHeaderFmt MUST be set to return 200 as described above in order to get the expected behaviour with all browsers.

%apply=item id=HTMLVSpace ?%$HTMLVSpace

Setting $HTMLVSpace = ''; in a local customizationfile (e.g., local/config.php) prevents insertion of spacer paragraphs (<p class='vspace'></p>) in generated HTML code. To limit this change to a single skin, place the $HTMLVSpace = ''; statement in a skin.php file, preceded by the statement global $HTMLVSpace;.

%apply=item id=HTMLPNewline ?%$HTMLPNewline

This variable allows to enable linebreaks by default, i.e. without having the directive (:linebreaks:) in a page or in a GroupHeader. To enable line breaks, add to config.php such a line:
$HTMLPNewline = '<br/>';

%apply=item id=SimpleTableDefaultClassName ?%$SimpleTableDefaultClassName

This variable can contain a CSS classname to be used for simple tables, if a "class=" attribute is not defined in the wiki page (default unset):
$SimpleTableDefaultClassName = "wikisimpletable";
See for sample code PITS:00638.

%apply=item id=EnableSimpleTableRowspan ?%$EnableSimpleTableRowspan

If set to 1, will enable features replicating the recipe Cookbook:RowspanInSimpleTables (default disabled).
$EnableSimpleTableRowspan = 1; # See recipe

%apply=item id=EnableSortable ?%$EnableSortable

Set this variable to 1 to enable sortable tables, see Tables#sortable (default disabled):

$EnableSortable = 1; # Enable sortable tables

%apply=item id=TableCellAttrFmt ?%$TableCellAttrFmt

For Tables, defines the HTML attributes given to each <td> or <th> cell in the output. Can contain references to $TableCellCount which holds the horizontal column number of the current cell.

%apply=item id=TableCellAlignFmt ?%$TableCellAlignFmt

For Tables, defines the HTML attributes for alignment of each <td> or <th> cell. Default is " align='%s'" where %s will be replaced with 'center', 'left' or 'right'. For a valid HTML5 ? output you may want to change this in config.php:
$TableCellAlignFmt = " class='%s'";
then define the CSS classes td.center, td.right and td.left (also th).

%apply=item id=TableRowAttrFmt ?%$TableRowAttrFmt

For Tables, defines the HTML attributes given to each <tr> element in the output. Can contain references to $TableRowCount to give the absolute row number within the table, or $TableRowIndex to provide a repeating row index from 1 to $TableRowIndexMax.

        # Give each row a unique CSS class based on row number (tr1, tr2, tr3, ... )
        $TableRowAttrFmt = "class='tr\$TableRowCount'";
        # Give each row alternating CSS classes (ti1, ti2, ti1, ti2, ti1, ... )
        $TableRowIndexMax = 2;
        $TableRowAttrFmt = "class='ti\$TableRowIndex'";

%apply=item id=TableRowIndexMax ?%$TableRowIndexMax: The maximum value for $TableRowIndex in Tables.

        # Set rows indexes as 1, 2, 3, 1, 2, 3, 1, 2, ...
        $TableRowIndexMax = 3;

%apply=item id=EnableTableAutoValignTop ?%$EnableTableAutoValignTop: Advanced tables are intended for layout, and automatically insert the valign='top' attribute if there is no valign attribute defined in the markup source. Setting this variable to 0 in config.php will prevent the automatic addition.

        $EnableTableAutoValignTop = 0; # disable automatic valign='top' attr

%apply=item id=EnableAutoSkinList ?%$EnableAutoSkinList: This variable enables the change of the skin from the URL to any skin available on the wiki installation. See also $PageSkinList and Skins:SkinChange.
%apply=item id=PageSkinList ?%$PageSkinList: This is an array of allowed skins that can be changed by the visitor with ?skin= or ?setskin= URL query to the wiki. See also $EnableAutoSkinList and Skins:SkinChange.
$FmtV['$TableCellCount']: PMWiki ? internal variable - Horizontal column number of the current cell. For use in $TableCellAttrFmt and $TableRowAttrFmt. Administrators can use in $TableCellAttrFmt and/or $TableRowAttrFmt.

        Example: $TableCellAttrFmt = 'class=col\$TableCellCount';

$FmtV['$TableRowCount']: PMWiki ? internal variable - Current row number. Administrators can use in $TableCellAttrFmt and/or $TableRowAttrFmt.

        Example: TableRowAttrFmt = "class='row\$TableRowCount'";

$FmtV['$TableRowIndex']: PMWiki ? internal variable - Row index number derived from $TableRowIndexMax. (1,2,3,1,2,3,...). Administrators can use in $TableCellAttrFmt and/or $TableRowAttrFmt.

        Example: $TableRowAttrFmt = "class='ind\$TableRowIndex'";
