rtrim

  • Stripping whitespace from the end of a string is done in Ruby using the String#rstrip method.

    PHP

    $result = rtrim("hello world \n");
var_export($result);
// => 'hello world'

    Ruby

    p "hello world \n".rstrip
# => "hello world"

    PHP’s rtrim function has a second argument to specify the characters to strip. We can do this in Ruby using the String#gsub method.

    PHP

    $result = rtrim("/Users/joe/work/ ", " /");
var_export($result);
// => '/Users/joe/work'

    Ruby

    chars = " /"
p "/Users/joe/work/ ".gsub(/[#{chars}]+$/, '')
# => "/Users/joe/work"
