Timbre, a logging library for Clojure

Logging with Java can be maddeningly, unnecessarily hard. Particularly if all you want is something simple that works out the box.

tools.logging helps, but it doesn't save you from the mess of logger dependencies and configuration hell.

Timbre is an attempt to make simple logging simple and more complex logging possible.

What's In The Box?

• Small, uncomplicated all-Clojure library.
• Map-based config: no arcane XML or properties files.
• Decent performance (low overhead).
• Flexible fn-centric appender model.
• Sensible built-in appenders including simple email appender.
• Tunable flood control.
• Asynchronous logging support.

Status

Timbre was built in a day after I finally lost my patience trying to configure Log4j. I tried to keep the design simple and sensible, but I didn't spend much time thinking about it so there may still be room for improvement. In particular, the configuration and appender formats are still subject to change.

Getting Started

Leiningen

Depend on [timbre "0.5.0-SNAPSHOT"] in your project.clj and use the library:

(ns my-app
  (:use [timbre.core :as timbre :only (trace debug info warn error fatal spy)])

Start Logging

TODO: Out-the-box std-out examples

Configuration

TODO: Config format (assoc) & appenders. Recommend just viewing source for now.
