Overview

Manages logger creation for classes which mixin RSI::Loggable. LogManager has default settings for the log directory (Dir::tmpdir) and for the log file name (“app.log”).

If you’d like to override the defaults, call #root=() and/or #log_filename=() before LogManager is first used (ie, before RSI::Loggable#logger() is called the first time). You can also supply an arbitrary IO to #root_fh=() .

By default, the LogManager will create logs with level set to Logger::INFO. Individual classes mixing in RSI::Loggable may choose to override this by calling #logger.level=() .
