Logging Ruby

And just like log4j, Logging Ruby can be adapted for any use case, adding custom log input sources, output destinations and log levels.

At this moment, Logging Ruby can save logged data to these destinations:
Buffer
Email
Growl
File
IO
Stderr
Stdout
StringIo
Syslog

More documentation can be found in the project's README file.

A gem is also provided in the downloads section.

If Logging Ruby is not what you've been looking for, a good alternative is Log4R, another log4j inspired project.

Features:

• Support for hierarchical logging
• Custom log formats
• Custom log levels
• Custom log level names
• Log to multiple destinations
