Hello all!

What is the best way to something similar to what Enum.chunk does in elixir?  
Let’s say that I have a list and I want to take every 7 items and paint them.

Thank you!

I’m happy to answer your question, but I think we may be facing an [X/Y problem](http://xyproblem.info/). What are you trying to accomplish? There may be a specific piece of knowledge someone has that may solve the problem you’re actually having. 🙂

That said, here’s how you’d chunk a list into groups of seven, with a list of whatever remains at the end.

```elm
sevens : List a -> List (List a)
sevens mapper items =
    case items of
        a :: b :: c :: d :: e :: f :: g :: rest ->
            [a, b, c, d, e, f, g] : sevens rest

        _ ->
            items

```

I might try it another way. Here’s an Ellie: [https://ellie-app.com/nWknYsnhNa1/1](https://ellie-app.com/nWknYsnhNa1/1) 🙂

I believe [List.Extra.greedyGroupsOf](http://package.elm-lang.org/packages/elm-community/list-extra/7.1.0/List-Extra#greedyGroupsOf) also does what you’re asking.
