红宝石中的版本排序(带有Alpha，Beta等) [英] Version sort (with alphas, betas, etc.) in ruby

问题描述

如何在Ruby中对版本列表进行排序?我已经看过有关自然排序的内容，但这已经超出了这一步.

How do I sort a list of versions in Ruby? I've seen stuff about natural sort, but this is a step beyond that.

输入是一串这样的字符串:

Input is a bunch of strings like this:

input = ['10.0.0b12', '10.0.0b3', '10.0.0a2', '9.0.10', '9.0.3']

我几乎可以使用自然 gem做到这一点:

I can almost do it with the naturally gem:

require 'naturally'
Naturally.sort(input)
=> ["9.0.3", "9.0.10", "10.0.0a2", "10.0.0b12", "10.0.0b3"]    

问题:10.0.0b3在10.0.0b12之后排序； 10.0.0b3应该是第一个.

Problem: 10.0.0b3 is sorted after 10.0.0b12; 10.0.0b3 should be first.

任何人都有可行的方法吗?其他语言也有帮助！

Anyone have a way that works? Other languages are helpful too!

推荐答案

Ruby随Gem类一起提供，该类了解版本:

Ruby ships with the Gem class, which knows about versions:

ar = ['10.0.0b12', '10.0.0b3', '10.0.0a2', '9.0.10', '9.0.3']

p ar.sort_by { |v| Gem::Version.new(v) }
# => ["9.0.3", "9.0.10", "10.0.0a2", "10.0.0b3", "10.0.0b12"]
