分離元音和輔音

Question

如何從字符串中分離元音和輔音以創建過濾器？

我怎麼能代替輔音和元音與其他字母

我想出了這個

(\A[^aeio]{1,3})(\w*)/ 

同時在線搜索，但不知道它是如何工作的過去^aeio濾波部分，以得到輔音。

Answer 1

你是說像這樣分裂？

1.9.3-p327 > s = "abcqwertyaeiouvbnmi" 
=> "abcqwertyaeiouvbnmi" 
1.9.3-p327 > s.split(/([aeiou]+)/) 
=> ["", "a", "bcqw", "e", "rty", "aeiou", "vbnm", "i"] 

如果是這樣，那麼你可以循環訪問結果數組，替換字符。

Answer 2

s = "iamagoodboy" 
v,c = s.chars.partition{|i| ["a","e","i","o","u"].include?(i)} 
p v #=> ["i", "a", "a", "o", "o", "o"] 
p C#=> ["m", "g", "d", "b", "y"] 

現在，您可以根據需要在v和c迭代。

String.tr有利於轉換文本：

str = "while searching online, but not sure exactly how it works past the filtering part of ^aeio, to get consonants." 
p str.tr('aeiou', '') 
#=> "whl srchng nln, bt nt sr xctly hw t wrks pst th fltrng prt f ^, t gt cnsnnts." 
p str.tr('^aeiou', '') # the^negates 
#=>"ieeaioieuoueeaoioaeieiaoaeiooeooa" 
p str.tr('aeiou', 'eioua') 
#=>"wholi sierchong unloni, bat nut sari ixectly huw ot wurks pest thi foltirong pert uf ^eiou, tu git cunsunents."
