Setup Nim

An action for setting up the Nim environment for use within Github Actions. This includes:

• The full Nim toolchain built by the official builder at nim-lang/nightlies.
• A problem matcher for converting compiler errors/warnings into annotations.

Usage

See action.yml

Note: It is recommended to use a tagged version at the moment instead of master. This makes sure that future backward-incompatible changes will not cause your CI to fail suddenly. See the Update section for how to keep the action up-to-date.

Basic:

steps:
  - uses: alaviss/setup-nim@0.1.1
    with:
      version: 'version-1-4' # The Nim nightly version branch to download
      path: 'nim' # The directory relative to ${{ github.workspace }} to
                  # store the downloaded toolchain
  - uses: actions/checkout@v2
  - run: nimble build

Matrix testing:

jobs:
  test:
    strategy:
      matrix:
        os: ['windows-latest', 'macos-latest', 'ubuntu-latest']
        nim: ['devel', 'version-1-4', 'version-1-0']

    name: Nim ${{ matrix.nim }} on ${{ matrix.os }}
    runs-on: ${{ matrix.os }}
    steps:
      - uses: actions/checkout@v2
      - uses: alaviss/setup-nim@0.1.1
        with:
          path: 'nim'
          version: ${{ matrix.nim }}
      - run: nimble test

Testing 32bit Windows:

jobs:
  test:
    name: Nim 32bit on Windows

Update

Github's Dependabot can be used to keep actions up-to-date, see here for more information.

Example .github/dependabot.yml (copied from Github Docs):

version: 2

updates:
  - package-ecosystem: "github-actions"
    directory: "/"
    schedule:
      # Check for updates to GitHub Actions every weekday
      interval: "daily"
