Toolchain

revdeprun provisions just enough of a toolchain to make R CMD check work across a wide range of packages.

R version resolution

R versions are resolved via the R-hub R versions API.

This supports the r-lib/actions/setup-r style shorthands like:

  • release (default)
  • devel
  • oldrel-1
  • explicit versions like 4.3.3

See src/r_version.rs.

R installation

On Ubuntu, revdeprun downloads the platform-specific .deb, installs prerequisites, and installs the package with gdebi. It then creates stable symlinks in /usr/local/bin so that R and Rscript are on PATH.

See src/r_install.rs.

If you already have R, use --skip-r-install to reuse it.

Quarto, pandoc, TinyTeX

Many packages build vignettes. That means you need tooling.

revdeprun will install:

  • Quarto (if missing), pinned to the latest stable release at runtime.
  • pandoc (via apt).
  • TinyTeX (via quarto install tinytex) and symlinks for common TeX binaries.

The goal here is not a perfect TeX setup. Instead, the goal is "enough that R CMD check doesn't fail for boring reasons".
