Common CI workflow

This goal of this repo is to define a single Github workflow which will be used in multiple Status projects which share the same common steps required for testing:

• setting up the build matrix (different OSes, different Nim versions)
• installing the build dependencies
• building Nim and Nimble
• running the tests

Usage

To use this workflow, in the project's .github/workflows/<name>.ymlyou need to refer to it inside of jobs.<name>.uses field.
For example, the full file might look like this:

name: CI
on:
  push:
    branches:
      - master
  pull_request:
  workflow_dispatch:

jobs:
  build:
    uses: status-im/nimbus-common-workflow/.github/workflows/common.yml@main

By default, it is assumed that your project uses nimble test for its testing.

Customizing the test command

In a case where you don't just run nimble test, or when you need some additional commands (e.g. installing additional libraries) before running the tests, you can specify the jobs.<name>.with.test-command.
For example:

name: CI
on:
  push:
    branches:
      - master
  pull_request:
  workflow_dispatch:

jobs:
  build:
    uses: status-im/nimbus-common-workflow/.github/workflows/common.yml@main
    with:
      test-command: |
          nimble install -y toml_serialization json_serialization unittest2
          nimble test

Or to run several different test commands:

name: CI
on:
  push:
    branches:
      - master
  pull_request:
  workflow_dispatch:

jobs:
  build:
    uses: status-im/nimbus-common-workflow/.github/workflows/common.yml@main
    with:
      test-command: |
          nimble install -y libbacktrace
          nimble test
          nimble test_libbacktrace
          nimble examples

Customizing the Nim versions used in testing

By default, this workflow tests a package with the following Nim versions:

• version-1-6
• version-2-0
• version-2-2
• devel

To test with a different set of Nim versions, specify them in jobs.<name>.with.nim-versions using the following syntax (make sure to include both outer single quotes and inner double quotes as in the example):

name: CI
on:
  push:
    branches:
      - master
  pull_request:
  workflow_dispatch:

jobs:
  build:
    uses: status-im/nimbus-common-workflow/.github/workflows/common.yml@main
    with:
      nim-versions: '["version-2-0", "version-2-2"]'
