setup-racket

This action sets up a Racket environment for use in GitHub Actions.

Usage

See action.yml and this article for a tutorial on how to use it.

Basic

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'  # or: 'x64', 'x86', 'arm32', 'arm64' (or 'aarch64')
    distribution: 'full' # or: 'minimal' (but you probably don't want 'minimal', see note at the bottom of this doc)
    variant: 'CS'        # or: 'BC' for Racket Before Chez
    version: '8.14'      # or: 'stable' for the latest version, 'current' for the latest snapshot, 'pre-release' for the latest pre-release build
- run: racket hello.rkt

Package Installation

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'
    distribution: 'full'
    variant: 'CS'
    version: '8.14'
- run: raco pkg install --auto component koyo
- run: racket hello.rkt

Caching

You can use actions/cache in combination with setup-racket to reduce the time spent installing dependencies. See this repo for an example.

Custom Locations (only on Linux)

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'
    distribution: 'full'
    variant: 'CS'
    version: '8.14'
    dest: '/opt/racket' # ignored on macOS and Windows
- run: racket hello.rkt

When dest is provided, the destination installation's bin folder is prepended to the PATH. When you install multiple Racket versions to separate destinations, the last one you install will be the one that's found in the PATH when you invoke racket from a shell (unless you use an absolute path).

Disable sudo

Only on Linux. The default is to use sudo if the command exists.

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'
    distribution: 'full'
    variant: 'CS'
    version: '8.14'
    dest: '$GITHUB_WORKSPACE/racket'
    sudo: never # either 'always' or 'never'
- run: "$GITHUB_WORKSPACE/racket/bin/racket" hello.rkt

Matrix Testing

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        racket-version: [ '8.11', '8.12', '8.13', '8.14' ]
    name: Racket ${{ matrix.racket-version }} sample
    steps:
      - uses: actions/checkout@master
      - name: Setup Racket
        uses: Bogdanp/setup-racket@v1.11
        with:
          architecture: x64
          version: ${{ matrix.racket-version }}
      - run: racket hello.rkt

Local Package Catalogs

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'
    distribution: 'minimal'
    variant: 'CS'
    version: '8.14'
    dest: '/opt/racket'
    sudo: never
    local_catalogs: $GITHUB_WORKSPACE

This sets up a local package catalog at $GITHUB_WORKSPACE/catalog that has higher priority than the catalogs that come with the Racket distribution. This can come in handy when testing libraries that are a part of the main Racket distribution.

You can provide multiple local catalog paths by separating them with commas. They are prepended to the catalog set in order so the first local catalog in the list will have the highest priority.

Snapshot Sites

By default, snapshots are downloaded from whichever snapshot site (between the Utah snapshot site and the Northwestern site) has built a snapshot most recently. You can select a specific snapshot site using the snapshot_site option.

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    architecture: 'x64'
    distribution: 'full'
    variant: 'CS'
    version: 'current'
    snapshot_site: 'northwestern' # or: 'auto', 'utah' (defaults to 'auto')
- run: racket hello.rkt

Gotchas

minimal vs full distribution

Using the full distribution instead of the minimal distribution will reduce your build times for most use cases. Things you typically do in CI (run tests, build docs, etc.) require many dependencies not included in the minimal distribution, so you waste a lot of time downloading and installing those dependencies. The full distribution comes with those dependencies pre-installed. Only use the minimal distribution if you really know what you're doing.

CPU Architecture Notes

Installers for arm32 are only currently available when the version is current and arm64 installers are currently not available at all.

Installers for Apple Silicon Macs are available when the version is current and the arch is either arm64 or aarch64.

Using racket/gui

Tests which require racket/gui, even without using any graphical features, will fail due to not having a display. To get around this, use gabrielbb/xvfb-action to run your code like so:

steps:
- uses: actions/checkout@master
- uses: Bogdanp/setup-racket@v1.11
  with:
    version: 'stable'
- uses: GabrielBB/xvfb-action@v1
  with:
      run: racket hello.rkt
