# Dummy

Not a real driver, just an example how you could write your own driver in 12 lines. This one does, well, nothing useful.

```ruby
irb(main):001:1* class Dummy
irb(main):002:2*   def inc(keys:, **values)
irb(main):003:2*     keys.map { |key| puts "Incrementing #{key} => #{values}" }
irb(main):004:1*   end
irb(main):005:2*   def set(keys:, **values)
irb(main):006:2*     keys.map { |key| puts "Setting #{key} => #{values}" }
irb(main):007:1*   end
irb(main):008:2*   def get(keys:)
irb(main):009:3*     keys.map do |key|
irb(main):010:3*       puts "Random for #{key}"
irb(main):011:3*       { count: rand(1000) }
irb(main):012:2*     end
irb(main):013:1*   end
irb(main):012:0> end
=> :get
```

## Configuration & Interaction

Use it with configuration

```ruby
irb(main):013:0> c = Trifle::Stats::Configuration.new
=> #<Trifle::Stats::Configuration:0x00007fe179aed848 @separator="::", @ranges=[:minute, :hour, :day, :week, :month, :quarter, :year], @beginning_of_week=:monday, @time_zone="GMT">

irb(main):014:0> c.driver = Dummy.new
=> #<Dummy:0x00007fe176302ac8>

irb(main):015:0> c.track_ranges = [:minute, :hour]
=> [:minute, :hour]

irb(main):016:0> Trifle::Stats.track(keys: ['sample'], at: Time.now, values: {count: 1}, config: c)
Incrementing ["sample", :minute, 1655361000] => {:count=>1}
Incrementing ["sample", :hour, 1655359200] => {:count=>1}
=> [nil, nil]

irb(main):017:0> Trifle::Stats.values(keys: ['sample'], from: Time.now, to: Time.now, range: :hour, config: c)
Random for ["sample", :hour, 1655359200]
=> {:at=>[2022-06-16 06:00:00 +0000], :values=>[{:count=>852}]}
```

## Driver & Interaction

```ruby
irb(main):013:0> driver = Dummy.new
=> #<Dummy:0x00007ff6aa9313b0>

irb(main):014:0> driver.get(keys: [['test', 'now']])
Random for ["test", "now"]
=> [{:count=>526}]

irb(main):015:0> driver.inc(keys: [['test', 'now']], count: 1, success: 1, error: 0)
Incrementing ["test", "now"] => {:count=>1, :success=>1, :error=>0}
=> nil
irb(main):016:0> driver.get(keys: [['test', 'now']])
Random for ["test", "now"]
=> [{:count=>705}]

irb(main):017:0> driver.inc(keys: [['test', 'now']], count: 1, success: 0, error: 1, account: { count: 1 })
Incrementing ["test", "now"] => {:count=>1, :success=>0, :error=>1, :account=>{:count=>1}}
=> nil
irb(main):018:0> driver.get(keys: [['test', 'now']])
Random for ["test", "now"]
=> {:count=>959}
```

You can see, not useful at all!
