This repository contains an opinionated GitHub Action allowing you to simultaneously setup a specific version of Elixir and Erlang while also caching your build's dependencies and compilation.

Add the following step to a GitHub Actions workflow.

- name: Setup Elixir
  uses: perxhealth/setup-elixir-action@v1
  with:
    otp-version: 25.2.2
    elixir-version: 1.14.3-otp-25

The Action currently expects two required inputs.

1. otp-version

   the Erlang/OTP version you wish to install, such as 25.2.1, 26.0.1, etc.

2. elixir-version

   the Elixir version you wish to install, such as 1.14.3, 1.14.3-otp-25, etc.

The Action does not currently produce any outputs.

This is a composite action, so development is limited to and contained with action.yaml. Tweak it to your needs and open a pull request.

$ git clone [email protected]:perxhealth/setup-elixir-action
$ cd setup-elixir-action

On pushes to any branch, a workflow will run which performs a smoke test on the action. Once you've made any changes, ensure the workflow located at .github/workflows/preflight.yaml continues to pass.
