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.
