SumStrings

Simple gem which allows you to sum array of strings values. Primary ment for summing array of hours in format ["20:25","10:10"].strings_to_sum(':'). Which will result in a string 30:35.

Code solution used by sample provided on stackoverflow by Cary Swoveland, thanks.

Add this line to your application's Gemfile:

gem 'sum_strings'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sum_strings

Sample for summing array of string values like hours. We have array with some hours which we need to sum. Sample array: working_hours = ["09:20","5:10","08:00","23:20","10:13"]

Summing this array we can do like: working_hours.sum_strings(':')

The gem is extended method of ruby Array calss so calling method sum_strings(':') with providing split char as parameter.

Result would be: 56:3

In case that you have some other split char you just need to provide it to a method. Sample: working_hours = ["09-20","5-10","08-00","23-20","10-13"] sum_strings('-')

Here is a simple project where you can see practical usage of the gem https://github.com/nezirz/use_sum_strings
