I have this array of time values:
["00:04:48.563044", "00:05:29.835918", "00:09:38.622569"]
But I need to pass each array item through a parser (in this case, chronic_duration), and then spit it back out in to an array.
So each array item would need to get passed through:
ChronicDuration.parse('00:04:48.563044')
And then put back in an array:
[288.563044, 329.835918, 578.622569]
Two obvious options; new array, or in-place.
pry(main)> arr = ["00:04:48.563044", "00:05:29.835918", "00:09:38.622569"];
pry(main)> arr.collect! { |s| ChronicDuration.parse s }
=> [288.563044, 329.835918, 578.622569]
To create a new array, leave off the exclamation point ("!") on the collect call:
pry(main)> new_arr = arr.collect { |s| ChronicDuration.parse s }
You might want to map from one to the other:
pry(main)> h = Hash[arr.collect { |s| [s, ChronicDuration.parse(s)] }]
=> {"00:04:48.563044"=>288.563044,
"00:05:29.835918"=>329.835918,
"00:09:38.622569"=>578.622569}
Or switch the keys/values to allow easy sorting; either switching the collect array, or inverting:
pry(main)> h.invert.keys.sort.each_with_index {|k, i| puts "#{i+1}: #{h[k]}"}
1: 00:04:48.563044
2: 00:05:29.835918
3: 00:09:38.622569
