Transformation: Format the Table

Create formatted table

All that’s left from our design is to create the formatted table. The following would be a nice interface:

def process({user, project, count}) do   
  Issues.GithubIssues.fetch(user, project)
  |> decode_response()
  |> sort_into_ascending_order()
  |> last(count)
  |> print_table_for_columns(["number", "created_at", "title"])
end

We pass the formatter the list of columns to include in the table, and it writes the table to standard output. The formatter doesn’t add any new project- or design-related techniques, so we’ll just show the listing in the table_formatter.ex file.

And here are the tests for it. Use the mix test command to run the code below.
