clojure.edn

edn reading.

Extensible Data Notation is a subset of the Clojure language used as a data transfer format, designed to be used in a similar way to JSON or XML.

At some point in your adventures in Clojure land, you'll want to deserialize some clojure data structures from a string, and you'll want to use clojure.edn/read or clojure.edn/read-string for that. Do not use the read-* functions in clojure.core to deserialize untrusted Clojure code, as they can be unsafe.

read
Reads the next object from stream, which must be an instance of java.io.PushbackReader or some derivee. stream defaults to the current value of *in*. Reads data in the edn format (subset of Clojure data): http://edn-format.org opts is a map that can include the following keys: :eof - value to return on end-of-file. When not supplied, eof throws an exception. :readers - a map of tag symbols to data-reader functions to be considered before default-data-readers. When not supplied, only the default-data-readers will be used. :default - A function of two args, that will, if present and no reader is found for a tag, be called with the tag and the value.
read-string
Reads one object from the string s. Returns nil when s is nil or empty. Reads data in the edn format (subset of Clojure data): http://edn-format.org opts is a map as per clojure.edn/read
