• Labels:

  • reader
• Environment:

  clojure 1.5 beta2, Mac OS X 10.8.2, java version "1.6.0_37"

If a data-reader returns nil, the reader throws java.lang.RuntimeException: No dispatch macro... The error message implies that there is no dispatch macro for whatever the first character of the tag happens to be.

Here's a simple example:

(binding [*data-readers* {'f/ignore (constantly nil)}] (read-string "#f/ignore 42 10"))

RuntimeException No dispatch macro for: f clojure.lang.Util.runtimeException (Util.java:219)
