quickr vs saperlipopette: at a glance
What is quickr?
quickr's R-to-Fortran compiler now handles matrices, closures and OpenMP.
quickr compiles a subset of R to Fortran and calls it back from R, so numerical code can run without hand-writing C or Fortran. Version 0.3.0 is the release where that subset stops being small: matrix and linear algebra operations lower to the same BLAS/LAPACK that R uses, local closures and sapply() are supported with copy-on-modify semantics preserved, and for loops and sapply() calls can be marked for OpenMP parallelism via declare(parallel()).
What is saperlipopette?
saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.

◆ Current state
quickr compiles a subset of R to Fortran and calls it back from R, so numerical code can run without hand-writing C or Fortran. Version 0.3.0 is the release where that subset stops being small: matrix and linear algebra operations lower to the same BLAS/LAPACK that R uses, local closures and sapply() are supported with copy-on-modify semantics preserved, and for loops and sapply() calls can be marked for OpenMP parallelism via declare(parallel()).
◆ Where it's heading
The first two releases filled in language basics, control flow, arithmetic operators, multiple return values. Version 0.3.0 shifts to the constructs real numerical code is actually written in, and the compiler work underneath it, nested compilation scopes and block-scoped temporaries, is aimed at large functions and heap-versus-stack control for big temporaries. Toolchain work points the same way: LLVM flang is used on macOS when present, and the minimum R version was lowered to 4.3.0 to widen who can install it.
◆ Prediction
Expect the next releases to keep extending the compilable subset toward the remaining apply-family functions and to build out the parallelism story that declare(parallel()) opens.

◆ Current state
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
◆ Where it's heading
The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
◆ Prediction
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.
