    Ruby :

    • similar to issues noted in the above, there are lots of non-scan solutions that are avoiding the intended solution which isn't enforced by the test suite

    This Kata likely won't get approved unless :

    • the description is clarified to allow any function to make the desired result happen (in which cases it is ~8 kyu)

    • if that happens, the kata is likely going to get flagged because then it becomes a very basic grouping Kata

    • a lot of restrictions are in place to force someone to either just use match or put a lot of work to get around blocks

    Nice work on the test suite, aside from that anyway.

    Fun little kata. Might it make sense to disable other things like eval, split, and maybe even match itself, and add test cases that include other characters? I might definitely have misunderstood your intent.. I was thinking along the lines of a kata that has to do something a little more step-by-step than in one line. If so, ignore me :)

      Hi @Firefly2002, thank you for your feedback. It's very nice when my work is intresting and dose not waste. This kata is a challange for users of local ruby chat and investigation of Ruby regex. History of creation this kata: I got this js regex /([?!])\1*/ from solution of Exclamation marks series #18 kata, translating to Ruby found different in behaviour in Ruby/JS regex ( https://goo.gl/4vpKb6 ) . This leads to argue in the local chat, so I created kata to find ways to use Ruby.match work as like JS.match with particular regex.

    So if your intent is to disable the use of scan, you need to actually disable it (by un-defining it in preloaded.

    Also you should make sure we're not using other regexes.

      I thought it possible to solve this problem using s.match(some_other_regex).some_other_method_may_be but I do not think in this situation need to prevent other regex.

      But it's interesting what tis preloaded and how to wield with them. At curren moment I tured off scan by rewriting scan method.

      And also it's intersting how it's possible to prevent othre regex techically. Thank you

      Pass in the regex as a parameter?

      Pass in the regex as a parameter?

      I'm not sure what is a question? You mean rewrite method and check do regex equal to some othre ethalon?

      Ethalon = /aaa/
def String.match regex
  return fails_test if regex != Ethalon
  super
end
