Hi everyone,

I’ve released this new GitHub Actions called Elixir Script, because I wanted a way to script various tasks in my GitHub Actions workflows and wished for a way to use Elixir to do it.

Thus: ElixirScript, a Github Action to run Elixir code in workflow steps.

It works by taking a script as input, which gets run, and then the script’s return is available in outputs.result for later steps to use. Like this:

.github/workflows/example.yml:

- uses: gaggle/elixir_script@v0
  id: script
  with:
    script: |
      defmodule Greeter do
        def greet(name), do: "Oh hi #{name}!"
      end
      Greeter.greet("Mark")

- name: Get result
  run: echo "${{steps.script.outputs.result}}"
  # Echos "Oh hi Mark!"

And the script is run with bindings to the GitHub Actions context that caused the run, so it’s easy to react to run-specific information. For example, :

  script: |
    "🚀 Pushed to #{context.payload.repository.name} by @#{context.actor}! 

I think it’s a pretty easy, very low-friction way of getting to write some of the devopsy glue-code automations in Elixir. And it was a lot of fun to write as I got to learn about Elixir and GitHub Actions .

Happy to hear any thoughts, feedback, suggestions, etc.
