Data::GUID::Any - Generic interface for GUID/UUID creation
use Data::GUID::Any 'guid_as_string';
my $guid = guid_as_string();
This module is a generic wrapper around various ways of obtaining Globally Unique ID's (GUID's), also known as Universally Unique Identifiers (UUID's).
On installation, if Data::GUID::Any can't detect a way of generating both version 1 and version 4 GUID's, it will add either Data::UUID::MT or UUID::Tiny as a prerequisite, depending on whether or not a compiler is available.
For legacy compatibility with Data::UUID, guid strings are returned uppercase, even though RFC 4122 specifies that generators should provide lower-case strings. To force lower case results from Data::GUID::Any, set $Data::GUID::Any::UC to a false value.
guid_as_string(); # will be lower case
The following functions are available for export.
my $guid = guid_as_string();
Returns a guid in string format with upper-case hex characters:
This is the most general subroutine that offers the least amount of control over the result. This routine returns whatever is the default type of GUID for a source, which could be version 1 or version 4 (or, in the case of Win32, something resembling a version 1, but specific to Microsoft).
It will use any of the following sources, listed from most preferred to least preferred:
Data::UUID::LibUUID (v4 or v1)
UUID (v4 or v1)
Win32 (using GuidGen()) (similar to v1)
uuid (external program) (v1)
APR::UUID (v4 or v1)
At least one of them is guaranteed to exist or Data::GUID::Any will throw an exception when loaded. This shouldn't happen if prerequisites were correctly installed.
my $guid = v1_guid_as_string();
Returns a version 1 (timestamp+MAC/random-identifier) GUID in string format with upper-case hex characters from one of the following sources:
uuid (external program)
If none of them are available, an exception will be thrown when this is called. This shouldn't happen if prerequisites were correctly installed.
my $guid = v4_guid_as_string();
Returns a version 4 (random) GUID in string format with upper-case hex characters from one of the following modules:
RFC 4122 [http://tools.ietf.org/html/rfc4122]
