MediaWiki版本:

  • 'wikidiff''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';
