I have the following module in my priv/ directory:

defmodule MyModule do
    def hello(s) do
        IO.puts s
    end
    hello("world")
end

when I mix run priv/funwithfuncs.exs:
** (CompileError) priv/funwithfuncs.exs:5: undefined function hello/1

How do I define a function in a seed/exs file??

When you try to call hello/1 it does not exist.

If you though call that function after that module has been fully created (thats with the end that belongs to defmodule M do) then it works:

$ cat foo.exs
defmodule M do
  def hello(s), do: IO.puts(s)
end

M.hello "World"

$ elixir foo.exs
World
