tidyCpp 0.0.9 on CRAN: More (forced) Maintenance

Wed, 04 Mar 2026 06:54:00 CDT

Another maintenance release of the tidyCpp package arrived on CRAN this morning. The packages offers a clean C++ layer (as well as one small C++ helper class) on top of the C API for R which aims to make use of this robust (if awkward) C API a little easier and more consistent. See the vignette for motivating examples.

This release follows a similar release in November and had its hand forced by rather abrupt and forced overnight changes in R-devel, this time the removal of VECTOR_PTR in [this commit]. The release also contains changes accumulated since the last release (including some kindly contritbuted by Ivan) and those are signs that the R Core team can do more coordinated release management when they try a little harder.

Changes are summarize in the NEWS entry that follows.

Changes in tidyCpp version 0.0.9 (2026-03-03)

Several vignette typos have been corrected (#4 addressing #3)

A badge for r-universe has been added to the README.md

The vignette is now served via GitHub Pages and that version is referenced in the README.

Two entry points reintroduced and redefined using permitted R API function (Ivan Krylov in #5).

Another entry has been removed to match R-devel API changes.

Six new attributes helpers have been added for R 4.6.0 or later.

VECTOR_PTR_RO(x) replaces the removed VECTOR_PTR, a warning or deprecation period would have been nice here.

Thanks to my CRANberries, there is also a diffstat report for this release. For questions, suggestions, or issues please use the issue tracker at the GitHub repo.
