NAME

TAP::Parser::YAMLish::Writer - Write YAMLish data

VERSION

Version 3.17

SYNOPSIS

    use TAP::Parser::YAMLish::Writer;
    
    my $data = {
        one => 1,
        two => 2,
        three => [ 1, 2, 3 ],
    };
    
    my $yw = TAP::Parser::YAMLish::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 YAMLish.

METHODS

Class Methods

"new"

 my $writer = TAP::Parser::YAMLish::Writer->new;

The constructor "new" creates and returns an empty "TAP::Parser::YAMLish::Writer" object.

Instance Methods

"write"

 $writer->write($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 = TAP::Parser::YAMLish::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.
