SemanticSort

Sorts strings containing numbers in a semantic way.

This gem was created to practice gem creation.
We recommend the following mainstream gems that have the same functionality.

• https://github.com/rwz/natural_sort

Created based on my gist.

Installation

gem install semantic_sort

Usage

require 'semantic_sort'

puts ['1', '10', '02'].sort           # => ['02', '1', '10']
puts ['1', '10', '02'].semantic_sort   # => ['1', '02', '10']

Sorting Method

• Start
  • ['003.txt', '02.txt', '1.txt']
• Append 0 to the left to match the maximum length of the number sequence
  • ['003.txt', '002.txt', '001.txt']
• Sort
  • ['001.txt', '002.txt', '003.txt']
• Delete unnecessary zeros
  • ['1.txt', '02.txt', '003.txt']
