The following actions are available only if you set $EnableDiag = 1; in your configuration file. They can be used for debugging and should not be set in a production environment.
- ?action=ruleset
- displays a list of all markups in 4 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)
- column 4 = Debug backtrace information for potentially incompatible rules (filename, line number, pattern)
?action=ruleset gives you, apply the Cookbook:MarkupRulesetDebugging recipe: it can also show the pattern and the replacement strings.
- doesn't make use of PmWiki's authorization mechanisms.
- ?action=phpinfo
- displays the output of phpinfo() and exits. No page will be processed
- doesn't make use of PmWiki's authorization mechanisms.
- ?action=diag
- displays a dump of all global vars and exits. No page will be processed
- doesn't make use of PmWiki's authorization mechanisms.
- $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.
- $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
