DebugVariables
The following actions are available only if you set $EnableDiag = 1;
- ?action=ruleset
- displays a list of all markups in 3 columns:
- column 1 = markup-name (1. parameter of markup() )
- column 2 = when will rule apply (2. parameter of markup() )
- column 3 = PmWiki's internal sort key (derived from #2)
(see Custom Markup Using the Markup() function for custom wiki syntax ).
To see more than what
?action=ruleset gives you, apply the Cookbook:MarkupRulesetDebugging recipe: it can also show the pattern and the replacement strings.

$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.
$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.

Is it possible for someone with admin priviledges to always have access to debugging tools, without letting everyone else access them?
You can easily & automatically allow debugging for anyone with admin priviledges (meanwhile leaving it off for everyone else) by including this line in config.php - just be sure that 1) $EnableDiag is either null or set to 0, and 2) to include it near the end of config.php, AFTER declaring your passwords, and after any AuthUser or other priviledge settings:
if (CondAuth($pagename, 'admin'))$EnableDiag= 1; # allows admin to always call phpinfo, etc
