Tools to easy the debugging in DokuWiki are provided, some needs the enabling of debug config.

To provide more info for debugging DokuWiki has a config allowdebug that enable some debugging options. When enabled you can:

• Appending &do=debug so DokuWiki will output a huge list of debug strings.
• Look up output of dbglog() in data/cache/debug.log
• Receive additional error messages e.g. from some authentication backends

Insert a code block in the wikipage filled by $msg as plain text.

Adding an extra argument to dbg($msg, $hidden=true) will return the $msg as html comment.

Writes $msg to the log in the cache directory data/cache/debug.log when config allowdebug is enabled.

Use dbglog($msg, 'Header above log message') for including a header above $msg.

Print a reversed, prettyprinted backtrace

When you write your own debug functionality, use this function to remove all data from an array where the key seems to point to sensitive data.
