Please note: This action is not registered in the marketplace and is experimental. You can still use it in your own workflows by referencing it as angusmoore/julia-detect-dependabot@main. But please treat as experimental for now.

This action checks if the current branch that the action is running on is a CompatHelper or dependabot branch. If so, it sets an output variable is_dependabot that you can check in subsequent steps.

the julia-actions/julia-runtest action does this automatically when running tests. If you are using julia-runtest, you do not need this action.

This action is helpful if you are manually invoking Pkg.test() but want to be able to easily set force_latest_compatible_version on CompatHelper pull requests (as is now standard for julia-runtest. This situation might arise because you need to pass in custom arguments, or flags to the julia process that are not supported by julia-runtest.

See also these issues [1] [2] for discussion of automatically setting force_latest_compatible_version automatically in CI scrits, which this action tries to solve (specifically this is row 2 in [1]).

Julia needs to be installed before this action can run. This can easily be achieved with the setup-julia action.

You need to provide an id for the action, so that you can access the output variable is_dependabot in subsequent github actions steps.

You can access the result is_dependabot (which is a string of either "true" or "false") using the github actions steps context. Eg, if you set the id for the julia-detect-dependabot action as dependabot, you would access the value in subsequent steps as: ${{ steps.dependabot.outputs.is_dependabot }}

An example workflow that uses this action might look like this:

name: Run tests

on: [push, pull_request]

jobs:
  test:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        julia-version: ['1', 'nightly']
        julia-arch: [x64, x86]
        os: [ubuntu-latest]

    steps:
      - uses: actions/checkout@v2
      - uses: julia-actions/setup-julia@v1
        with:
          version: ${{ matrix.julia-version }}
          arch: ${{ matrix.julia-arch }}
      - uses: angusmoore/julia-detect-dependabot@main
        id: dependabot
      - name: Custom package tests
        run: |
            julia --project -e 'import Pkg; Pkg.test(; force_latest_compatible_version = parse(Bool, ENV["IS_DEPENDABOT"]))'
        env:
          is_dependabot: ${{ steps.dependabot.outputs.is_dependabot }}
