DESCRIPTION

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

CONFIGURATION

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
