This Action:

• Installs a Common Lisp compiler of your choice (SBCL, ECL, ABCL, or Clisp).
• Uses the vend tool to fetch dependencies.
• Enables trivial testing of your project.
• Caches your build artifacts (FASL files).

⚠ Currently only the ubuntu runner is supported.

• Usage
  • Basics
  • Compiler Selection
    • Matrices: a job per compiler

Create a .github/workflows/cl.yaml file with the following contents:

on:
  push:
    branches: [master]
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest
    name: Unit Tests
    steps:
      - name: Clone the Project
        uses: actions/checkout@v4

      - name: Set up Common Lisp
        uses: fosskers/common-lisp@v1

      - name: Test
        run: |
          vend test

Your dependencies will be automatically fetched by vend, so you’re free to do what you please in subseqent steps. In the example here, we simply call vend test, which returns the proper error code to fail the job if any tests failed.

By default vend operates with SBCL, but we can customize this:

- name: Install Vend
  uses: fosskers/common-lisp@v1
  with:
    compiler: ecl

then subsequent steps will have ECL available to them:

- name: Test
  run: |
    vend test ecl

Since you can only request one compiler at a time to be installed, but may want to test multiple of them, it’s useful to use a matrix. This will spawn a CI job per requested compiler:

on:
  push:
    branches: [master]
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest
    name: Unit Tests
    strategy:
      matrix:
        compiler: ["sbcl", "ecl"]
    steps:
      - name: Clone the Project
        uses: actions/checkout@v4

      - name: Set up Common Lisp
        uses: fosskers/common-lisp@v1
        with:
          compiler: ${{ matrix.compiler }}

      - name: Test
        run: |
          vend test ${{ matrix.compiler }}

Each per-compiler job will also get its own cache, so subsequent runs should be faster.
