Introduction

This is a simple library that converts the numbers range in human readable string to numeric type. For example: "1-2" to [1,2] or "1,3:5" to [1,3,4,5].

There are two separators, list_sep (default ,) and range_sep (default :), the string is first separated by the list separators, and then the individual part is considered a range, there are 3 types of ranges:

• number ⇒ Single number (e.g. 3)
• start:end ⇒ Inclusive Range with step 1 (e.g. 1:10)
• start:step:end ⇒ Inclusive Range with variable step (e.g. 1:2:10)
