The Micro-Manager acquisition engine, and the Data Browser plugin, are both written in the Clojure programming language. You can write your own Clojure scripts or Micro-Manager plugins using the Clojure Editor (described here), available under the Plugins menu .
Micro-Manager includes jars for the Clojure Core and Clojure Contrib on the class path. The Data Browser source code shows an example of a Micro-Manager plugin in written Clojure.
