In rmacoslib/r-macos-pkg-gha: What the Package Does (One Line, Title Case)

Providing macOS software used on CRAN for CI Systems and Local Use

The repository contains a way to re-create the software available on CRAN's macOS build systems within the GitHub Actions for R workflow for Continuous Integration (CI).

To accomplish this, we add a single step to the standard workflow from usethis that activates when the build container is running on macOS. The new step downloads and extracts all pre-made binaries on the libs-4 directory at the R macos developer portal. These binaries were created using the recipes system by Simon Urbanek, who is the official CRAN maintainer for macOS.

In short, we added:

- name: Install system dependencies for mac
  if: runner.os == 'MacOS'
  run: |
     curl -sL  https://mac.r-project.org/libs-4/ |
     sed -n 's/.*href=\([^>]*x86_64.tar.gz\).*/\1/p' |
     xargs -I % sh -c 'curl https://mac.r-project.org/libs-4/% --output %; sudo tar fxz % -C /usr/local --strip 2' 

Note: This is an unofficial project not associated with the CRAN team. The goal here is to show how to recreate on a CI system the binaries available on CRAN for testing packages.
