- * library; historically, Dave Raggett's "HTML Tidy" was typically used.
- * See https://www.w3.org/People/Raggett/tidy/
- *
- * Setting this to null is deprecated.
- *
- * If this is null and $wgUseTidy is true, the deprecated configuration
- * parameters will be used instead.
- *
- * If this is null and $wgUseTidy is false, a pure PHP fallback will be used.
- * (Equivalent to setting `$wgTidyConfig['driver'] = 'disabled'`.)
- *
- * Keys are:
- * - driver: May be:
- * - RemexHtml: Use the RemexHtml library in PHP
- * - RaggettInternalHHVM: Use the limited-functionality HHVM extension
- * Deprecated since 1.32.
- * - RaggettInternalPHP: Use the PECL extension
- * Deprecated since 1.32.
- * - RaggettExternal: Shell out to an external binary (tidyBin)
- * Deprecated since 1.32.
- * - disabled: Disable tidy pass and use a hacky pure PHP workaround
- * (this is what setting $wgUseTidy to false used to do)
- * Deprecated since 1.32.
- *
- * - 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.
+ * library; historically, other postprocessors were used.
+ *
+ * Setting this to null will use default settings.
+ *
+ * Keys include:
+ * - driver: formerly used to select a postprocessor; now ignored.
+ * - treeMutationTrace: a boolean to turn on Remex tracing
+ * - serializerTrace: a boolean to turn on Remex tracing
+ * - mungerTrace: a boolean to turn on Remex tracing
+ * - pwrap: whether <p> wrapping should be done (default true)
+ *
+ * See includes/tidy/RemexDriver.php for detail on configuration.
+ *
+ * Overriding the default configuration is strongly discouraged in
+ * production.
