Earmark is a pure-Elixir Markdown converter. It is intended to be used as a library (just call Earmark.as_html), but can also be used as a command-line tool (run mix escript.build first). Output generation is pluggable.

Retired package: Deprecated - Earmark is no longer maintained. Migrate to a replacement, for example MDEx (https://hex.pm/packages/mdex).

  `reduce_with_end` is like `Enum.reduce` for lists, but the reducer function is called for

  each element of the list with the tuple `{:element, element}` and the accumulator and once

  more at the end with `:end` and the accumulator



      iex(1)> reducer =

      ...(1)>   fn {:element, nil}, {partial, result} -> {[], [Enum.sum(partial)|result]}

      ...(1)>      {:element, val}, {partial, result} -> {[val|partial], result}

      ...(1)>      :end,            {partial, result} -> [Enum.sum(partial)|result] |> Enum.reverse

      ...(1)>   end

      ...(1)> [1, 2, nil, 4, 1, 0, nil, 3, 2, 2]

      ...(1)> |> reduce_with_end({[], []}, reducer)

      [3, 5, 7]



  **N.B.** that in the treatment of `:end` we can change the shape of the accumulator w/o any

  penalty concerning the complexity of the reducer function
