frontmatter vs quickr: at a glance
What is frontmatter?
A small R parser quietly becoming format-agnostic about front matter.
frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.
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()).

◆ Current state
frontmatter extracts and writes YAML or TOML front matter from text documents, with a C++ parser and pluggable YAML and TOML backends. Three releases across six months have taken it from read-only parsing to full roundtrip and then to inferring format automatically. Its scope is deliberately narrow: locating and delimiting the metadata block, and delegating the actual parsing to other packages.
◆ Where it's heading
Each release widens the set of files it recognises without widening what it claims to do — standard YAML and TOML fences first, then comment-wrapped R and Python variants and PEP 723 inline script metadata, then shebang-prefixed scripts. The complementary thread is preserving what it found: format and fence type are attached as attributes so a document can be rewritten in the style it arrived in. The remaining rough edge is acknowledged in the notes, since comments and formatting inside the front matter do not survive a roundtrip.
◆ Prediction
Expect further delimiter styles as they appear in the wild, and likely work on making the roundtrip preserve comments and formatting, which the package currently flags as imperfect.
quickr
0.0INFRA · APIS
quickr's R-to-Fortran compiler now handles matrices, closures and OpenMP.
◆ 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.
