Define my own reader macro in clojure

It is possible to create tagged literals by having a reader map in data_readers.clj at the top of your classpath.

This must be in data_readers.clj at the top of your classpath (usually src directory).

{ß reader-demo.core/read-fn} 

This goes into reader-demo.core

(defn some-func [arg] (str "some-func invoked with " arg)) (defn read-fn [arg] (-> arg keyword some-func)) 

Invoking

#ß foo 

will return

"some-func invoked with :foo" 

This technique is described here: The reader: Tagged literals

Notice that in practice you should namespace your tagged literals as all non-namespaced ones are reserved for Clojure itself.
