Sorry but this is another release announcement.
I just rewrite my node-geohash module with clojure. You can include it with leiningen according to the instructions shows here. The project is hosted on bitbucket this time. The API is rather simple, please just follow the README doc.
It’s totally different experience to write such kind of algorithm in a functional language. You have to translate loops to recursions, also make sure they are available for tail recursion optimization. I really enjoy coding in clojure.
