OneLang test issues

[Tamás Koczka]

• Python: else indentation breaks logic
• Python: Tokenizer::offset is not initalized to 0 in __init__
• Python: static method StringHelper::starts_with_at_index has self argument and no @staticmethod attribute
• Swift: Tokenizer::init uses ! for setting operators field
• Swift: Tokenizer::tokenize: fix empty array init (var result = [] -> var result = [Token]())
• Swift: convert substrings to string (str[x ..< y] -> String(str[x ..< y]))
• Swift: do not force unwrap operators at foreach (for curr_op in self.operators! -> for curr_op in self.operators)
• Swift: static methods should be prefixed with class (func startsWithAtIndex -> class func startsWithAtIndex)
• Swift: nullability fixes... (eg. return [Token]? instead of [Token] and force unwrap every nullable value on access)
• Java: infer foreach item type (instead of Object)
• Java: use equals instead of == for comparison between strings (StringHelper.startsWithAtIndex)
• Ruby: create accessors for static fields

    class << self
      attr_accessor :identifier
    end

• Ruby: fix infinite loop (comparison issue?)
• C++: add ; after break
• C++: prefix static methods with static (make StringHelper::startsWithAtIndex static)
• C++: unify reference handling (make everything shared pointer? so sp<vector<sp<object>>>>???)
  • fix vector initialization
  • fix return value type
  • fix class field type
• Go: replace OneArray with concrete type (eg. []string or []Token)
• Go: use for instead of while
• Go: fix static methods
• Go: find out how to use array with custom class (eg. []*Token)
• JavaScript: initialize variable (Tokenizer::constructor: this.offset = 0;)
• JavaScript: use static prefix for static methods (StringHelper::startsWithAtIndex)
• Perl: fix array initializer
• Perl: fix infinite loop bug
