Catmandu::Exporter - Namespace for packages that can export
package Catmandu::Exporter::Foo; use Catmandu::Sane; use Moo; with 'Catmandu::Exporter' sub add { my ($self, $data) = @_; my $fh = $self->fh; $fh->print( ... ); } package main; use Catmandu; my $exporter = Catmandu->exporter('Foo', file => "/tmp/output.txt"); # Or on the command line $ catmandu convert JSON to Foo < /tmp/something.txt >/tmp/output.txt
A Catmandu::Exporter is a Perl package that can export data. By default, data items are written to STDOUT. Optionally provide a file or fh parameter to write to a file, string, or handle. New exporter modules are expected to use the print method of fh.
file
fh
print
Every Catmandu::Exporter is a Catmandu::Fixable thus provides a fix parameter and method to apply fixes to exported items.
fix
Every Catmandu::Exporter is a Catmandu::Addable thus inherits the methods add and add_many.
add
add_many
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.
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.
Binmode of the output stream fh. Set to ":utf8" by default.
:utf8
An ARRAY of one or more fixes or file scripts to be applied to exported items.
Adds one object to be exported.
Adds many objects to be exported. This can be either an ARRAY-ref or an Catmandu::Iterator. Returns a true value when the export was successful or undef on error.
Returns the number of items exported by this Catmandu::Exporter.
Returns the current logger.
See function export_to_string in module Catmandu.
The exporters Catmandu::Exporter::JSON, Catmandu::Exporter::YAML, Catmandu::Exporter::CSV, and Catmandu::Exporter::RIS are included in Catmandu core.
See Catmandu::Importer for the opposite action.
