NAME
Data::YAML::Reader - Parse YAML created by Data::YAML::Writer
VERSION
This document describes Data::YAML::Reader version 0.0.6
SYNOPSIS
use Data::YAML::Reader;
my $yr = Data::YAML::Reader->new;
# Read from an array...
my $from_array = $yr->read( @some_array );
# ...an open file handle...
my $from_handle = $yr->read( $some_file );
# ...a string containing YAML...
my $from_string = $yr->read( $some_string );
# ...or a closure
my $from_code = $yr->read( sub { return get_next_line() } );
DESCRIPTION
In the spirit of YAML::Tiny this is a lightweight, dependency-free YAML reader. 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 accepted by "Data::YAML::Reader" is a subset of YAML. Specifically it is the same subset of YAML that Data::YAML::Writer
produces. See Data::YAML for more information.
INTERFACE
"new"
Creates and returns an empty "Data::YAML::Reader" object. No options may be passed.
"read( $source )"
Read YAML and return the data structure it represents. The YAML data may be supplied by a
o scalar string containing YAML source
o the handle of an open file
o a reference to an array of lines
o a code reference
In the case of a code reference a subroutine (most likely a closure) that returns successive lines of YAML must be supplied. Lines
should have no trailing newline. When the YAML is exhausted the subroutine must return undef.
Returns the data structure (specifically either a scalar, hash ref or array ref) that results from decoding the YAML.
"get_raw"
Return the raw YAML source from the most recent "read".
BUGS AND LIMITATIONS
No bugs have been reported.
