`use-public-rspm` not respected w/ renv

[akgold]

Is your feature request related to a problem? Please describe. When I use setup-renv, the use-public-rspm flag on install-r doesn't seem to apply.

Describe the solution you'd like I would like the repos in my renv.lock to use public RSPM if the use-public-rspm flag is invoked on install-r.

Alternatively, the ability to manually set a repo on the use-renv action would be fine.

Describe alternatives you've considered I'm not sure there are any good ones. I could avoid renv.

Or I could switch to public RSPM on my laptop, but that's not great, because then I don't get package binaries for Mac.

Additional context Here's what my workflow looks like:

jobs:
  render-book:
    name: Render-Book
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v1
      - uses: quarto-dev/quarto-actions/install-quarto@v1
      - uses: r-lib/actions/setup-r@v2
        with:
          use-public-rspm: true

      - uses: r-lib/actions/setup-renv@v2

      - run: |
          quarto --version
      - name: Render Book
        run: |
          quarto render .
      - uses: actions/upload-artifact@v2
        with:
          name: _site
          path: _book/

@akgold, the scenario in which you have a specific repo in the lock file but would like to use a different one for CI is supported in renv via option renv.config.repos.override or the equivalent environment variable RENV_CONFIG_REPOS_OVERRIDE (see https://rstudio.github.io/renv/reference/config.html#details)

Given this, the approach

Alternatively, the ability to manually set a repo on the use-renv action would be fine.

should be achievable by setting RENV_CONFIG_REPOS_OVERRIDE

[akgold]

Yep, makes sense. It would be nice ergonomics if that got set automatically based on use-public-rspm.

How would one set RENV_CONFIG_REPOS_OVERRIDE in the context of the r-lib/actions/setup-renv@v2 action?

Try https://docs.github.com/en/actions/learn-github-actions/environment-variables

It's like this, for anyone else who was confused:

- name: Set up Renv
    uses: r-lib/actions/setup-renv@v2
    with:
      cache-version: 2
    env:
      RENV_CONFIG_REPOS_OVERRIDE: "https://packagemanager.rstudio.com/all/latest"

[riccardoporreca]

@millerh1, glad to see the approach of using RENV_CONFIG_REPOS_OVERRIDE is working.

As a further refinement, you can actually leverage the fact that setup-r defines an RSPM environment variable with the repos URL. Besides avoiding to write and maintain the URL in the workflow, this has the advantage of relying on the actual OS-specific repository as constructed dynamically by setup-r, especially relevant for Linux binaries, e.g. https://packagemanager.rstudio.com/all/linux/focal/latest

See e.g. the env. variable in your own workflow: https://github.com/Bishop-Laboratory/RLBase/runs/7061924670?check_suite_focus=true#step:5:9

The following should do the job:

    env:
      RENV_CONFIG_REPOS_OVERRIDE: ${{ env.RSPM }}

[millerh1]

That's a great trick! Thanks for sharing :)
