Print object to PrintWriter out as JSON

DEPRECATED; replaced by 'write-str'. Converts x to a JSON-formatted string. Valid options are: :escape-unicode false to turn of \uXXXX escapes of Unicode characters.

Pretty-prints JSON representation of x to *out*. Options are the same as for write except :value-fn, which is not supported.

DEPRECATED; replaced by 'pprint'. Pretty-prints JSON representation of x to *out*. Valid options are: :escape-unicode false to turn off \uXXXX escapes of Unicode characters.

DEPRECATED; replaced by 'write' to *out*. Write JSON-formatted output to *out*. Valid options are: :escape-unicode false to turn off \uXXXX escapes of Unicode characters.

Reads a single item of JSON data from a java.io.Reader. Options are key-value pairs, valid options are: :eof-error? boolean If true (default) will throw exception if the stream is empty. :eof-value Object Object to return if the stream is empty and eof-error? is false. Default is nil. :bigdec boolean If true use BigDecimal for decimal numbers instead of Double. Default is false. :key-fn function Single-argument function called on JSON property names; return value will replace the property names in the output. Default is clojure.core/identity, use clojure.core/keyword to get keyword properties. :value-fn function Function to transform values in maps ("objects" in JSON) in the output. For each JSON property, value-fn is called with two arguments: the property name (transformed by key-fn) and the value. The return value of value-fn will replace the value in the output. If value-fn returns itself, the property will be omitted from the output. The default value-fn returns the value unchanged. This option does not apply to non-map collections.

DEPRECATED; replaced by read-str. Reads one JSON value from input String or Reader. If keywordize? is true (default), object keys will be converted to keywords. If eof-error? is true (default), empty input will throw an EOFException; if false EOF will return eof-value.

Reads one JSON value from input String. Options are the same as for read.

Write JSON-formatted output to a java.io.Writer. Options are key-value pairs, valid options are: :escape-unicode boolean If true (default) non-ASCII characters are escaped as \uXXXX :escape-js-separators boolean If true (default) the Unicode characters U+2028 and U+2029 will be escaped as \u2028 and \u2029 even if :escape-unicode is false. (These two characters are valid in pure JSON but are not valid in JavaScript strings.) :escape-slash boolean If true (default) the slash / is escaped as \/ :key-fn function Single-argument function called on map keys; return value will replace the property names in the output. Must return a string. Default calls clojure.core/name on symbols and keywords and clojure.core/str on everything else. :value-fn function Function to transform values in maps before writing. For each key-value pair in an input map, called with two arguments: the key (BEFORE transformation by key-fn) and the value. The return value of value-fn will replace the value in the output. If the return value is a number, boolean, string, or nil it will be included literally in the output. If the return value is a non-map collection, it will be processed recursively. If the return value is a map, it will be processed recursively, calling value-fn again on its key-value pairs. If value-fn returns itself, the key-value pair will be omitted from the output. This option does not apply to non-map collections.
