Why, in Ruby, does Array("foo\nbar") == ["foo\n", "bar"]?
- by Tyson
In Ruby 1.8.7, Array("hello\nhello") gives you ["hello\n", "hello"]. This does two things that I don't expect:
It splits the string on newlines. I'd expect it simply to give me an array with the string I pass in as its single element without modifying the data I pass in.
Even if you accept that it's reasonable to split a string when passing it to Array, why does it retain the newline character when "foo\nbar".split does not?
Additionally:
>> Array.[] "foo\nbar"
=> ["foo\nbar"]
>> Array.[] *"foo\nbar"
=> ["foo\n", "bar"]
