.tool-versions Action

This repository contains a GitHub Action allowing you to export environment variables and obtain Actions outputs as per your .tool-versions file.

Usage

For example, if your repository contains a .tool-versions which looks like the following...

nodejs 16.15.0
pnpm 7.26.1
elixir 1.14.3-otp-25
erlang 25.2.2

your environment will be updated with the following variables...

NODEJS_VERSION=16.15.0
PNPM_VERSION=7.26.1
ELIXIR_VERSION=1.14.3-otp-25
ERLANG_VERSION=25.2.2

The Action will also provide outputs accordingly. Following on from the examples above...

steps:
   - name: Parse versions
     id: versions
     uses: perxhealth/tool-versions-action@v1

   - name: Setup pnpm
     uses: pnpm/action-setup@v2
     with:
       version: ${{ steps.versions.outputs.pnpm_version }}

   - name: Setup node
     uses: actions/setup-node@v3
     with:
       node-version: ${{ steps.versions.outputs.nodejs_version }}

Inputs

The Action currently accepts a single, optional input.

  1. location

    Path on disk to the desired .tool-versions. defaults to ./.tool-versions.

Outputs

The Action provides a *_version output for each entry it finds in your .tool-versions. For example, if your .tool-versions contains an entry like nodejs 16.15.0, we'll produce an output like NODEJS_VERSION=16.15.0.

Development

Follow the below steps to get up and running with a local, development copy of the Action.

Prerequisites

You will need the following tools installed on your machine.

Clone the repository

$ git clone [email protected]:perxhealth/tool-versions-action
$ cd tool-versions-action

Install dependencies

Firstly, you'll want to ensure the correct versions of the necessary system dependencies are installed.

$ asdf install

Note: optionally, you may need to install the necessary asdf plugins first.

$ asdf plugin add nodejs
$ asdf plugin add pnpm

Lastly, go ahead and install the Action's dependencies via pnpm

$ pnpm install

Development

Edit src/index.ts to make your changes. There is no dev server to run, so after (or before!) making your changes, update src/index.test.ts to ensure the action still performs as expected.

The repo's maintainers will take care of packaging and releasing new versions after Pull Requests have been merged. Although, we plan to automate this in future if there's enough demand.

Testing

Ensure you write tests to cover any code or behaviour you introduce.

$ pnpm test
