Enabling logging

To enable logging in FireBreath, both for your own messages and the ones FireBreath generates, you need to do the following:

  1. add the following to your PluginConfig.cmake

  2. regenerate your project using the prep* scripts
  3. open up Factory.cpp in your project. You need to define the following function inside the class definition for PluginFactory:

  4. FireBreath will now log to the specified output. You can add your own log messages, by using the FBLOG_* macros that can be found in firebreath/src/ScriptingCore/logging.h.
