Tools for code similarity / detecting plagiarism

Hello,

As an I’m looking for tools to see code similarity between submitted projects written in Elixir. I’ve found :

  • MOSS (No Elixir support)
  • Atomic (No Elixir support)
  • PMD (No Elixir support)
  • CCFinder (No Elixir support)

Does the community has any suggestions as to what tools could be used for this?

Thank you in advance.
