PreviewChanges

Show highlighted changes of the wiki markup when previewing a modified page.

  $EnablePreviewChanges = 1;

Description

While editing a page in "preview" mode, a diff block is shown before the rendered page output. The diff block contains, like a page history, highlighted differences between the saved version of the page and the currently edited text.

Installation, PmWiki 2.2.118 or newer

Add to config.php:

  $EnablePreviewChanges = 1;

Installation, PmWiki 2.2.113 to 2.2.117

• Copy previewchanges.phpΔ to your pmwiki/cookbook directory.
• Add to config.php such a line:
  if(@$_REQUEST['preview']>'') include_once("$FarmD/cookbook/previewchanges.php");

Configuration

No configuration is required. The recipe will use the same functions that create and display the page history.

Usage

While modifying a page, press the "Preview" button. Above the rendered page output you will see a block with highlighted differences between the versions.
