Ruby中用于操作此字符串的简洁方法

Question

有时我喜欢学习如何以“Ruby”的方式做事。我想知道 - 采用如下字符串的最简洁，最可读的方式是什么：

foo-bar

并操纵它阅读：

Foo Bar

Answer 1

"foo-bar".split("-").map(&:capitalize).join(" ")

Answer 2

"foo-bar".gsub(/\b(\w)/){|m| m.capitalize}.sub '-', ' '

Answer 3

>> p "foo-bar".scan(/\w+/).map(&:capitalize).join(" ")
"Foo Bar"
=> "Foo Bar"
>> p "foo---bar".scan(/\w+/).map(&:capitalize).join(" ")
"Foo Bar"
=> "Foo Bar"
>> p "foo 123 bar".scan(/\w+/).map(&:capitalize).join(" ")
"Foo 123 Bar"
=> "Foo 123 Bar"

Answer 4

string = "foo-bar"
"foo-bar".split("-").map(&:capitalize).join(" ") # edited to because former answer was not optimal
