DESCRIPTION

       This Catmandu::Exporter exports items serialized in JSON format. By default each item is
       printed condensed on one line.

CONFIGURATION

       file
           Write output to a local file given by its path or file handle.  Alternatively a scalar
           reference can be passed to write to a string and a code reference can be used to write
           to a callback function.

       fh  Write the output to an IO::Handle. If not specified, Catmandu::Util::io is used to
           create the output handle from the "file" argument or by using STDOUT.

       fix An ARRAY of one or more fixes or file scripts to be applied to exported items.

       encoding
           Binmode of the output stream "fh". Set to "":utf8"" by default.

       pretty
           Pretty-print JSON

       indent
       space_before
       space_after
       canonical
           JSON serialization options

       array
           Structure the data as a JSON array. Default is 1.

       line_delimited
           Export items as newline delimited JSON. Default is 0. The "array", "pretty", "indent",
           "space_before" and "space_after" options will be ignored if "line_delimited" is 1.
