Cycle randomly through the given list with guarantee every element of the list is used once before elements are being picked again. This is done by keeping a list of remaining elements that have not been picked yet. The list of remaining element is returned, as well as the randomly picked element.

Example

my_cycle = cycle_start ~w(1 2 3)
cycle my_cycle #=> 2
cycle my_cycle #=> 3
cycle my_cycle #=> 1

Start a cycle. See cycle/1

Get a random digit as a string; one of 0-9

Format a string with randomly generated data. Format specifiers are replaced by random values. A format specifier follows this prototype:

%[length]specifier

The following specifier rules are present by default:

• d: digits 0-9
• a: lowercase letter a-z
• A: uppercase letter A-Z
• b: anycase letter a-z, A-Z

The specifier rules can be overriden using the second argument.

Examples

format("%2d-%3d %a%A %2d%%") #=> "74-381 sK 32%"
format("%8nBATMAN", n: fn() -> "nana " end) #=> "nana nana nana nana nana nana nana nana BATMAN"

Execute fun n times with the index as first param and join the results with joiner

Examples

join(3, ", ", &Faker.Code.isbn13/0) # => "9785053574562, 9787187574302, 9798231475230"
