Debug Variables

%apply=item id=Abort Function?%$AbortFunction

A custom function name replacing the built-in Abort() function.

%apply=item id=Enable Diag?%$EnableDiag

%apply=item id=Enable Markup Diag?%$EnableMarkupDiag

By default, the "ruleset" action will display all markup rules, and the old-format patterns requiring update for PHP 7 will list with their files and line numbers. Setting $EnableMarkupDiag to 1 will list files and line numbers of all patterns. Note, this needs to be set early in config.php before a Markup() call or before including a recipe.

%apply=item id=Enable IMS Caching?%$EnableIMSCaching

A variable which, when set equal to 1, recognizes the "If-Modified-Since" header coming from browsers and allows browsers to use locally cached pages. Disabled by default to help the administrator customize its page without needing permanent reloading.

%apply=item id=Enable Stop Watch?%$EnableStopWatch

This activates an internal stopwatch that shows how long it takes to render a page. (If you have a wiki that composes a HTML page from multiple pages, such as a normal layout with a sidebar, you'll get separate timings for each subpage and for the total page.)

The timings can be displayed by adding <!--function:StopWatchHTML 1--> in the wiki template.

Valid values are:

        $EnableStopWatch = 0; # No timings (the default). No HTML will be generated.
        $EnableStopWatch = 1; # Wall-clock timings only.
        $EnableStopWatch = 2; # Wall-clock and CPU usage timings. Won't work on Windows.

See Stopwatch for more details.
