细节

要使用的外部差异引擎的名称，或设置为false以使用内部引擎。

可能的值：

• false - 如果可用的话，使用wikidiff2 ，否则使用PHP实现。

• 任何其他字符串都被视为外部差异可执行文件的路径。

The following values are no longer supported as of MW 1.32:

MediaWiki版本：

≤ 1.32

• 'wikidiff2' - 作为PHP/HHVM模块实现的维基媒体的快速差分引擎。

The following values are no longer supported as of MW 1.27:

MediaWiki版本：

≤ 1.27

• 'wikidiff'和'wikidiff3' - 被视为false，以向后兼容。

The external engine should return HTML for a table row containing four columns (two 'marker/content' pairs). These can be collapsed into one for diff formats that don't require columns, e.g. <tr><td colspan="4"> … </td></tr>

此设置代替了$wgUseExternalDiffEngine 。

Example

To display diffs in the format of the common GNU diff program, it is necessary to wrap that executable in a small script such as the following. This is needed both to get the required HTML wrapper, and also because diff returns non-zero when inputs don't match (which they generally don't for wiki changes).

• externaldiff.sh

  #!/bin/bash
  
  echo "<tr><td colspan=4><pre>"
  # @todo This should also escape HTML.
  diff "$1" "$2"
  DIFFRET=$?
  echo "</pre></td></tr>"
  
  if [[ $DIFFRET -eq 1 ]]; then
      exit 0
  else
      exit $DIFFRET
  fi
  

• LocalSettings.php

  $wgDiffEngine = 'external';
  $wgExternalDiffEngine = '/path/to/externaldiff.sh';
