This document describes Data::YAML::Writer version 0.0.6

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 \s-1YAML\s0.

In the spirit of YAML::Tiny this is a lightweight, dependency-free \s-1YAML\s0 writer. While \*(C`YAML::Tiny\*(C' is designed principally for working with configuration files \*(C`Data::YAML\*(C' concentrates on the transparent round-tripping of \s-1YAML\s0 serialized Perl data structures.

The syntax produced by \*(C`Data::YAML::Writer\*(C' is a subset of \s-1YAML\s0. Specifically it is the same subset of \s-1YAML\s0 that Data::YAML::Reader consumes. See Data::YAML for more information.

INTERFACE

The constructor \*(C`new\*(C' creates and returns an empty \*(C`Data::YAML::Writer\*(C' object. Encode a scalar, hash reference or array reference as \s-1YAML\s0. 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 \s-1YAML\s0 to

  • the handle of an open file

  • a reference to an array into which \s-1YAML\s0 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.

No bugs have been reported.
