Installation

And then execute:

$ bundle

Or install it yourself as:

$ gem install tablecloth

Usage

Scenario: Something interesting involing a table transformation
  Given the world functions as expected
  When we have a list of orders like:
    | Order ID | Transaction ID | Amount |
    | 1        | 124            | $50    |
    |          | 456            | $100   |
    | 2        | 789            | $75    |
  Then something magical should happen

# register transformations
Transproc.register(:to_money) do |value, world|
  Money.new(value.gsub("$", "").to_i * 100, world.currency)
end

table(/^table:Order ID,Transaction ID,Amount$/) do
  column :order_id, type: :integer, from: "Order ID", retain_previous_value: true
  column :transaction_id, type: :integer, from: "Transaction ID"
  column :amount, type: :money, from: "Amount"
end

TableStep(/we have a list of orders like:/) do |table|
  table # => [
        #      {order_id: 1, transaction_id: 124, amount: money(50_00)},
        #      {order_id: 1, transaction_id: 456, amount: money(100_00)},
        #      {order_id: 2, transaction_id: 789, amount: money(75_00)},
        #    ]
end
