This page is intended to describe features of PmWiki 1.0 that have been changed or eliminated in PmWiki 2.0. For now this page will be maintained a simple list and will probably need some restructuring later.

Markup changes

• Double brackets are used for all links, including [[free links]]. Providing alternate text for a link is performed using either a vertical brace [[PageName | link text]] or an arrow [[link text -> PageName]]. See http://www.pmwiki.org/pmwiki2/pmwiki.php/PmWiki/LinkSyntax.

• So far, the ThisPage:, ThisGroup:, etc., InterMap shortcuts are not defined. In fact, they may not be needed in PmWiki 2. If someone needs them, add an entry to PITS:NewIssue explaining why.
  
  Ok, so as an example, how next lines, which are in a sidebar, may be written in pmwiki2 ?
  *[[ThisPage:?action=upload Upload]]
  *[[ThisGroup:SideBar&action=edit Edit menu]]

Customization changes

• The $BrowseReplacements, $DoubleBrackets, and $InlineReplacements arrays are no longer used -- see custom markup.

• ?action=post no longer exists -- posting a new page is now performed by using ?action=edit with the post control set to a true value.

• $WikiWordPagePathFmt is now $PagePathFmt, which is applied to all page links not qualified by a group.

• $WikiPageExistsFmt, $WikiPageCreateFmt, etc. are now $LinkPageExistsFmt, $LinkPageCreateFmt, etc.

• $DeleteKeyWord is now $DeleteKeyPattern.

• In $...Fmt strings, $Title_ and $Title are currently represented by $Name. In the future, $Title will be used to refer to a page's title (which may be different from its name).

• $GroupHeaderFmt and $GroupFooterFmt now specify the markup to be added to the beginning and end of each page, rather than the name of the page. The default settings of $GroupHeaderFmt and $GroupFooterFmt perform the equivalent of an (:include:) of the GroupHeader? and GroupFooter? pages.

• The css/stdlayout.css file no longer exists; PmWiki now places its basic formatting styles directly into the $HTMLStylesFmt array.

• PmWiki's ReadPage() function no longer supplies default text for non-existent pages -- this is now decided by whatever functions need the page. (As of 2.0.devel9 the default text is still stored in $DefaultPageTextFmt, however.)

• $SearchExcludePatterns is now simply $SearchPatterns and can be chosen by the list= parameter to (:searchresults:) and (:pagelist:). See Cookbook:SearchResults.

• $PageName is now $FullName. $PageName still functions but will be removed in the 2.0 official release.

• $HTMLTitleFmt is deprecated -- it still works but will be removed in the 2.0 official release.

• $EnablePerGroupCust is now $EnablePGCust.
