masa-iwasaki / setup-rbenv

Set up your GitHub Actions workflow with rbenv

DO NOT USE THIS ACTION

ruby/setup-ruby provides everything that this action has provided.

setup-rbenv

Setup Ruby by rbenv on Ubuntu 18.04 / 16.04 virtual environments, not using tool-cache provided by GitHub to catch up the latest versions of Ruby.

Usage

You need to initialize rbenv by dispatching eval "$(rbenv init -)" in each step before you run Ruby.

steps:
- uses: actions/checkout@master
- uses: masa-iwasaki/setup-rbenv@v1
- name: Install Ruby
  run: |
    eval "$(rbenv init -)"
    rbenv install -s `cat .ruby-version` # or specify the version you want

- name: Run bundler
  run: |
    eval "$(rbenv init -)"
    bundle install --path vendor/bundle

Cache

By using actions/cache, you can keep your rubies in your cache.

steps:
- uses: actions/checkout@master
- uses: masa-iwasaki/setup-rbenv@v1

- name: Cache RBENV_ROOT
  uses: actions/cache@v1
  id: cache_rbenv
  with:
    path: /home/runner/.rbenv
    key: ${{ runner.os }}-rbenv-${{ hashFiles('**/.ruby-version') }}
    restore-keys: |
      {{ runner.os }}-rbenv-

- name: Install Ruby
  run: |
    eval "$(rbenv init -)"
    rbenv install -s `cat .ruby-version`

You don't need to check cache hit because -s option for rbenv install does the job. You need to be aware of cache limits if you want to keep multiple rubies.
