About Tracy

Tracy library is a useful helper for everyday PHP programmers. It helps you to:

  • quickly detect and correct errors with an expandable call stack tree
  • log errors (and optionally receive emails when an error occurs in production mode)
  • dump variables
  • measure execution time of scripts/queries
  • see memory consumption between breakpoints

Module features

Includes config settings for a variety of Tracy options.

Many optional custom panels provide a wide variety of information and tools to help your development and debugging process. See the blog post for more details.

Additionally, content can be dumped to the page via TD::dump() or to the debug bar via TD::barDump(), or logged via TD::log() from PW template files. eg.

TD::debugAll($page, 'Current Page');
   Aliases;  debugAll(), da()

TD::barDump($page, 'Current Page');
   Aliases;  barDump(), bd()

   Aliases; dump(), d()

TD::log('Log Message');
    Alias; l()

TD::fireLog('Log Message');
    Alias; fireLog(), fl()

    Alias; addBreakpoint(), bp()

    Aliases; timer(), t()

By default, manually logged content is sent to: /site/assets/logs/tracy/info.log, but you can specify an optional second parameter to one of the following: 'debug', 'info', 'warning', 'error', 'exception', 'critical' files.

eg. TD::log('Log Message', 'debug'); which will put the message in the debug.log file.


To make fireLog work, you need to add some browser extensions:
