A simple logging facade for Node
Node.js logging facade to decouple frameworks, libraries and application code from specific logging implementations.
Adapters for different ruby logging backends. Create loggers using different adapters, like Logger (Stdlib), Rails or SLF4J (in JRuby only).
An adapter that makes it easy to use Log4j, Logback or any SLF4J compatible Java logger library through a Ruby standard library Logger interface
The Logback ruby gem packages the Logback[http://logback.qos.ch/] java log writer, and provides a JRuby facade for programmatic Logback setup. Logback implements the SLF4J[http://www.slf4j.org/] SPI packaged in the slf4j gem.
A JRuby adaption and gem packaging of the {Simple Logging Facade for Java}[http://www.slf4j.org/]. Provides all jar dependencies and a Ruby Logger compatible facade. SLF4J is a java logging abstraction and set of adapters to various concrete logging implementations and legacy logging APIs. The slf4j gem adds a ruby core Logger compatible facade to SLF4J, and makes any needed adapters available to JRuby applications. This makes it possible to unify and control logging output of both java and ruby components in a JRuby application.
