ruby - 区分元音和辅音

Question

如何将元音和辅音从字符串中分离出来，以创建过滤器？

如何用其他字母替换辅音和元音

我想出了这个

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

在线搜索时，但不确定它是如何通过 , 的过滤部分^aeio来获取辅音的。

Answer 1

String.tr适用于转换文本：

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."

Answer 2

你的意思是这样分开吗？

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

如果是这样，那么您可以在生成的数组中循环替换字符。

Answer 3

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"]

现在您可以根据需要v进行迭代c。
