This document describes Data::YAML::Writer version 0.0.7

SYNOPSIS

use Data::YAML::Writer;

my $data = {
one => 1,
two => 2,
three => [ 1, 2, 3 ],
};

my $yw = Data::YAML::Writer->new;

# Write to an array...
$yw->write( $data, \@some_array );

# ...an open file handle...
$yw->write( $data, $some_file_handle );

# ...a string ...
$yw->write( $data, \$some_string );

# ...or a closure
$yw->write( $data, sub {
my $line = shift;
print "$line\n";
} );

DESCRIPTION

Encodes a scalar, hash reference or array reference as YAML.

In the spirit of YAML::Tiny this is a lightweight, dependency-free YAML writer. While "YAML::Tiny" is designed principally for working with configuration files "Data::YAML" concentrates on the transparent round-tripping of YAML serialized Perl data structures.

The syntax produced by "Data::YAML::Writer" is a subset of YAML. Specifically it is the same subset of YAML that Data::YAML::Reader consumes. See Data::YAML for more information.

INTERFACE

"new"

The constructor "new" creates and returns an empty "Data::YAML::Writer" object.

"write( $obj, $output )"

Encode a scalar, hash reference or array reference as YAML.

    my $writer = sub {
        my $line = shift;
        print SOMEFILE "$line\n";
    };
    
    my $data = {
        one => 1,
        two => 2,
        three => [ 1, 2, 3 ],
    };
    
    my $yw = Data::YAML::Writer->new;
    $yw->write( $data, $writer );

The $output argument may be

• a reference to a scalar to append YAML to
• the handle of an open file
• a reference to an array into which YAML will be pushed
• a code reference

If you supply a code reference the subroutine will be called once for each line of output with the line as its only argument. Passed lines will have no trailing newline.
