NAME

Data::Random::Flexible - Flexible fast-to-write profilable randoms

VERSION

Version 1.06

SYNOPSIS

A more flexible set of randoms for when you want to be random FAST

    use Data::Random::Flexible;

    use feature "say";

    my $random = Data::Random::Flexible->new();

    say "32 Characters of random numbers?, sure: ".$random->int(32);

    say "16 Characters of random letters?, sure: ".$random->char(16);

    say "16 Of a mixture of numbers and letters?, sure: ".$random->mix(16);

    say "Random mixture of 16 your own characters?, sure: ".$random->profile('irc',16, [qw(I r C 1 2 3)]);
    
    say "Random mixture of 16 your own characters from a saved profile?, sure: ".$random->profile('irc',16);

The module can also use alternative providers for rand(), for more detail look at the engine() function, the currently supported providers of random are:

        Math::Random::Secure
        Math::Random::MTwist
        Math::Random::Xorshift
        Math::Random::MT
        Math::Random::ISAAC
        Math::Random::ISAAC::XS (Not selectable will be used AUTO if availible by Math::Random::ISAAC)
        Crypt::PRNG
        Your own code reference.

new()

Create a new Math::Random::Flexible object, accepts 1 optional argument, a hashref of profiles

engine()

Return a list of availible engines for rand(), by default the module will always use CORE::rand, that being perls inbuilt rand. If you want to change it simply provide your choice as the first argument.

If you pass in a reference to your own random function it will attempt a test against it if successful it will use that!

An example of passing your own:

    sub mycode { return int(rand(9)) }

    $random->engine(\&mycode);

If you pass something weird that is not a known engine or a reference, it will not switch engines but will raise a warning.

NOTE Normal every day users just wanting a nice way to get random numbers and such of a set length need not pay attention to it!

store()

Set and/or return the stored profiles, will always return the currently used profiles, unless you pass it something it did not expect as a first argument, where it will return a blank hashref.

alpha()

Return a random alpha character uppercase or lowercase, accepts 1 argument 'length', if length is ommited return a single alpha-char;

char()

Though technically wrong, it is a shorthand to alpha()

numeric()

Return a random whole number, accepts 1 argument 'length', if length is ommited return a single number.

int()

A shorthand for numeric()

alphanumeric()

Return a random alphanumeric string, accepts 1 argument 'length', if length is ommited return a single random alpha or number.

mix()

A shorthand for alphanumeric()

profile()

Set or adjust a profile of characters to be used for randoms, accepts 3 arguments in the following usages:

Create or edit a profile named some_name and return a 16 long string from it

$random->profile('some_name',16,[qw(1 2 3)]);

Return 16 chars from the pre-saved profile 'some_name'

$random->profile('some_name',16);

Delete a stored profile

$random->profile('some_name',0,[]);
