YAML::Any - Pick a YAML implementation and use it.
WARNING: This module will soon be deprecated. The plan is that YAML.pm itself will act like an Any module.
use YAML::Any; $YAML::Indent = 3; my $yaml = Dump(@objects);
There are several YAML implementations that support the Dump/Load API. This module selects the best one available and uses it.
Currently, YAML::Any will choose the first one of these YAML implementations that is installed on your system:
YAML::XS
YAML::Syck
YAML::Old
YAML
YAML::Tiny
If you specify an option like:
$YAML::Indent = 4;
And YAML::Any is using YAML::XS, it will use the proper variable: $YAML::XS::Indent.
Like all the YAML modules that YAML::Any uses, the following subroutines are exported by default:
Dump
Load
and the following subroutines are exportable by request:
DumpFile
LoadFile
YAML::Any provides the following class methods.
YAML::Any->order
This method returns a list of the current possible implementations that YAML::Any will search for.
YAML::Any->implementation
This method returns the implementation the YAML::Any will use. This result is obtained by finding the first member of YAML::Any->order that is either already loaded in %INC or that can be loaded using require. If no implementation is found, an error will be thrown.
%INC
require
Here is an example for DumpFile:
#!/usr/bin/perl use strict; use warnings; use YAML::Any qw(DumpFile); my $ds = { array => [5,6,100], string => "Hello", }; DumpFile("hello.yml", $ds);
When run, this creates a file called hello.yml in the current working directory, with the following contents.
hello.yml
--- array: - 5 - 6 - 100 string: Hello
In turn, the following LoadFile example, loads the contents from there and accesses them:
#!/usr/bin/perl use strict; use warnings; use YAML::Any qw(LoadFile); my ($ds) = LoadFile("hello.yml"); print "String == '", $ds->{string}, "'\n";
Assuming hello.yml exists, and is as created by the DumpFile example, it prints:
$ perl load.pl String == 'Hello' $
