Kohana provides us with a lot of information, useful for debugging, but there is no appropriate viewer for it (except of not very useful View::factory(‘profile/stats’)).
Problems of existing solutions
In fact, Kohana DevTools doesn’t solve the problem at all. It has a few nice features, but it doesn’t show the debugging information itself. Only a few variables are shown. And there have been no updates for the last two years.
Kohana Debug Toolbar solves the problem. However, it has its own ones. For example, it includes its html/js code into the page, and it can result in breaking the markup. Sure, you can disable this feature and use only FirePHP, but FirePHP doesn’t provide ability to show all the information that is needed.
All provided by Kohana debugging information we send over a custom HTTP header. And we created an extension for Google Chrome with a nice UI for it. For now it shows information about benchmarks, routes, sql queries, modules, included files. Soon it will allow to view the information about configs, logs, variables etc.
