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. For example, for Crystal there is 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.
