Overview

Module for generating generators (yes-yes)

Two commonly used (probably) strategies are pre-defined:

1. :abc - generates a/b/c/d... sequence
2. :a1a2 - generates a1/a2/a3... sequence

Examples:

g = Pry::Memory::Generators.new { |counter| counter * 2}
g.generate
# => 2
g.next!; g.generate
# => 4

Constant Summary collapse

PREDEFINED = 
{
  :abc => new { |counter| ('a'..'z').to_a[counter - 1] },
  :a1a2 => new { |counter| "a#{counter}" }
}
