Hi,

Out of the box Debug::log writes the date and a specified message to [root]/debug.log. I would like to add the name of the logged-in user and the filename and line number at which the log function was called.

I know how to do this by editing the function. However I want to achieve this by adding code to [my module]/code rather than changing code in sapphire.

Is there a neat way of doing this? Currently I have no idea.

Thanks.

In an attempt to extent debug::log without altering the Version 2.4 framework, I added the following line to mysite/_config.php

Object::add_extension("Debug", "CustomDebug");

created and added the following to mysite\code\CustomDebug.php

Then in order to make sure that the object gets built before the object is run I commented out the above line in mysite/_config.php,
ran dev/build,
removed the comment, and finally
re-ran dev/build.

However when I re-ran dev/build I got the following message

Fatal error: Object::add_extension() - Extension "CustomDebug" is not a subclass of Extension in [my root]\sapphire\core\Object.php on line 530

I have now spent some time trying to figure out where I screwed up so if anyone can spot anything that would be great. Maybe my line in _config.php is wrong.

If you want better support than what Debug::log() offers, you should be using SS_Log::log(). Your code doesn't work because Object::add_extension() is used to add extensions to objects, not to replace them. Object::useCustomClass() can be used to replace some classes in some places, but not debug as it is always called statically.
