You can declare dependencies at the top of a script file in a few languages, though usually through a third-party tool. I have a page on my site with a list of such languages and tools: https://dbohdan.com/scripts-with-dependencies https://dbohdan.com/scripts-with-dependencies. For example, for Crystal there is https://github.com/Val/crun https://github.com/Val/crun. I wish more developers knew about single-file scripts with dependencies. People seem to only discover them accidentally through a language or runtime that has the support built in. It means Elixir will contribute to the awareness, but Elixir itself is niche. Maybe Deno and Bun, as JavaScript runtimes, will popularize them. Having a common term not specific to any language may help, as there doesn't seem to be one. It hinders search. "(Single-file) scripts with dependencies" is what I have settled on. Edit: Added the Crystal example and the second paragraph.

I'll second @josevalim's comment, but I also wanted to mention how delighted I am to find out today that a joke[1] I probably spent way too much time 7 years ago has actually served a useful purpose! 1 - https://hex.pm/packages/leftpad https://hex.pm/packages/leftpad

  Ha! I just found this the other day and thought it was for real, lol. I wasn't actually looking for leftpad, of course, but, well done!

  Haha. Thanks for writing it. I appreciate your and every leftpad porter's effort. :-) It makes for a perfect little dependency test with a standardized name. (Standardized up to /left[_-]?pad/i.) When a language doesn't have a leftpad package, I go looking for a concise way to make terminal text bold, which takes more time. Plus, seeing code like https://github.com/colinrymer/leftpad.ex/blob/8d2230bf094eed83c89e42352a81de184cf154c2/lib/leftpad.ex https://github.com/colinrymer/leftpad.ex/blob/8d2230bf094eed... is just fun: defmodule Leftpad do @moduledoc """ Remembering `String.rjust/3` can be difficult, so Leftpad provides you another way to easily left pad/right justify your UTF-8 encoded binaries. """ @doc ~S""" Provides basically the same functionality as [`String.rjust/3`](http://elixir-lang.org/docs/stable/elixir/String.html#rjust/3) ## Examples iex> Leftpad.pad("foo", 5) " foo" iex> Leftpad.pad("foobar", 6) "foobar" iex> Leftpad.pad("1", 2, ?0) "01" """ @spec pad(string :: String.t, count :: non_neg_integer, char :: char) :: String.t def pad(string, count, char \\ 32), do: String.rjust(string, count, char) end Look at that one line doing all the work, and even it delegates it to another function.

    why not: defdelegate pad(string, count, char \\ 32), to: String, as: :rjust
