Details

Configuration for HTML postprocessing tool. Set this to a configuration array to enable an external tool. Dave Raggett's "HTML Tidy" is typically used. See http://www.w3.org/People/Raggett/tidy/.

The replacement for Tidy is going to be RemexHtml

If this is null and $wgUseTidy is true, the deprecated configuration parameters will be used instead. If this is null and $wgUseTidy is false, a pure PHP fallback will be used.

Keys are:

driver - May be:
- RaggettInternalHHVM - Use the limited-functionality HHVM extension
- RaggettInternalPHP - Use the PECL extension
- RaggettExternal - Shell out to an external binary (tidyBin)
- Html5Depurate - Use external Depurate service <translate> (removed in <tvar name=2>1.32</tvar>)</translate> Gerrit change 431531
- Html5Internal - Use the Balancer library in PHP <translate> (removed in <tvar name=2>1.32</tvar>)</translate> Gerrit change 431531
- RemexHtml - Use the RemexHtml library in PHP
tidyConfigFile - Path to configuration file for any of the Raggett drivers
debugComment - True to add a comment to the output with warning messages
tidyBin - For RaggettExternal, the path to the tidy binary.
tidyCommandLine - For RaggettExternal, additional command line options.

Example

Configure MediaWiki to use the tidy PECL package:

$wgTidyConfig = [
    'driver' => 'RaggettInternalPHP',
    'tidyConfigFile' => "$IP/includes/tidy/tidy.conf",
];

or to use the tidy binary:

$wgTidyConfig = [
    'driver' => 'RaggettExternal',
    'tidyConfigFile' => "$IP/includes/tidy/tidy.conf",
    'tidyBin' => 'tidy',
    'tidyCommandLine' => '',
];

The connection between $wgTidyConfig and the settings used by older MediaWiki versions ($wgTidyInternal , $wgUseTidy , $wgTidyBin , $wgTidyConf , $wgTidyOpts , $wgDebugTidy ) is roughly:

$wgTidyConfig = $wgUseTidy ? [
    'driver' => $wgTidyInternal ? 'RaggettInternalPHP' : 'RaggettExternal',
    'tidyConfigFile' => $wgTidyConf,
    'debugComment' => $wgDebugTidy,
    'tidyBin' => $wgTidyBin,
    'tidyCommandLine' => $wgTidyOpts,
] : null;
