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 objects 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.
