DESCRIPTION

This "Catmandu::Exporter" exports items as rows with comma-separated values (CSV). Serialization is based on Text::CSV. A header line with field names will be included if option "header" is set. See Catmandu::TabularExporter on how to configure the field mapping and column names. Newlines and tabulator values in field values are escaped as "\n", "\r", and "\t".

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.
sep_char
Column separator ("," by default)
quote_char
Quotation character (""" by default)
escape_char
Character for escaping inside quoted field (""" by default)
fields
See Catmandu::TabularExporter.
columns

header
