Summary

Log4r is a comprehensive and flexible logging library written in Ruby for use in Ruby programs.

More Info

Installation instructions are in the file INSTALLComprehensive examples are provided in examples/ and can be run right awayLog4r homepage: doc/index.htmlManual: doc/manual.htmlRDoc API reference: doc/rdoc/index.htmlThe changelogFeel free to bug the maintainer with any questions (listed at top of file)

Usability

Log4r works really well, so please take advantage of it right away! :) All versions since 0.9.2 have been stable and backward-compatible. The code is stable enough that updates are infrequent and usually only for adding features or keeping the code up to date with Ruby.

Platform Issues

Log4r is known to work on Linux and WindowsXP. It's safe to assume that Log4r will work on any Ruby-supported platform.

When Trouble Strikes

Log4r comes with an internal logger. To see its output, create a logger named 'log4r' before any others and give it a suitable outputter,

trouble = Logger.new['log4r'] trouble.add Outputter.stdout

Try running the unit tests provided (run the file tests/runtest.rb). Let the maintainer know what's up and feel free to explore and fix the code yourself. It's well documented and written in Ruby. :)
