Inform

Inform prints colourised, interactive logging output to the console. It includes support for timings and thread-local prefixes.

For example:

# Controllable log level filtering
Inform.level = :info

# Accept a block, print timing information once completed if > 0.1s
frozbot = Inform.info("Initializing the frozbot") do
  Frozbot.new
  sleep 1
end

# Other log levels than info
Inform.level = :debug
Inform.debug("Madness")
Inform.warning("and")
Inform.error("Nonsense")

# Thread-local log prefixing
Thread.current[:inform] = '1'
Inform.info("Frozbot is %{name}", :name => frozbot.name)

# Override output stream
buf = StringIO.new
Inform.output = buf
Inform.info("Loggable..")
buf.rewind
puts buf.read

Will print:

>>> Initializing the frozbot : Done (1.00s)
    Madness
WARNING: and
ERROR: Nonsense
1 *** Frozbot is myfrozbot

• Make debug, warning, error accept blocks
• Refactor tests
• Colourisation isn't tested at all - should it be?
• RDoc
