Log::SLF4J

Provides a jruby-compatible logger and Rails logger replacement that delegates to SLF4J.

This gem is adapted from rjack-slf4j by David Kellum in order to remove selection and bundling of SLF4J JARs. When the original gem is loaded by a Warbler-bundled jruby application multiple implementations of SLF4J are found on the classpath and SLF4J is unable to pick one.

Installation

Add this line to your application's Gemfile:

gem "log-slf4j", :github => "tomcz/log-slf4j", :tag => "0.0.3"
Note: the tag number should match the version of the gem.

And then execute:

$ bundle

NOTE: Unlike rjack-slf4j this gem does NOT bundle any SLF4J JARs so it is up to you to ensure that the slf4j-api-XXX.jar is present on the classpath along with a suitable implementation, such as slf4j-simple-XXX.jar or Logback.

Usage

require "log-slf4j"

// logger can be used directly
log = Log::SLF4J[ "my.app.logger" ]
log.info "Hello World!"

// or can replace the Rails logger
Rails.logger = Log::SLF4J[BookStore::Application]
