Mixin for Groovy language

Groovy is awesome. This library contains shortcuts to make your groovy development even more joyful.

Collections

Missing the sample function from Ruby? Here it is. By enabling this library you can

    [1, 2, 3, 4, 5].sample()  // Return 1 element randomly from array
    [1, 2, 3, 4, 5].sample    // Same as above: return 1 element randomly from array
    [1, 2, 3, 4, 5].sample(2) // Return 2 elements randomly from the array
    (1..5).sample()           // Return 1 element randomly from the range
    (1..5).sample             // Same as above: return 1 element randomly from the range

both gives you a random number from 1 to 5.

You can also verify if an element or array of elements are included in another array or range by using

    5.isPartOf [1, 2, 3, 4, 5] // Return true
    [1, 2].isPartOf [1, 2, 3]  // Return true
    3.isPartOf (1..5)          // Return true

Date

You can use the syntax below to get a dynamic date:

    5.years.ago
    1.months.ago
    2.days.ago
    4.hours.ago
    2.minutes.ago
    3.seconds.ago
    
    5.years.later
    1.months.later
    2.days.later
    3.hours.later
    2.minutes.later
    3.seconds.later 

Each returns a instance of Date relative to the execution time.
