rzig 0.2.3

CRAN resubmission

• Removed redundant wording from the package title and description.
• use_rzig() and document() now require an explicit package path, so neither function writes to the working directory by default.
• Added executable, temporary-directory examples for both exported functions; they use \donttest{} because they require the external Zig toolchain.
• document() now confines Zig’s local and global caches to an automatically cleaned R session temporary directory. On Unix, its compiler subprocess also receives a private temporary directory.

rzig 0.2.2

CRAN submission

• Updated the maintainer contact and added the author’s ORCID identifier.

rzig 0.2.1

Package authoring

• use_rzig() now scaffolds cleanup and cleanup.win, preventing generated Makevars and Zig build caches from entering source-package checks.
• document() uses the same Zig discovery order as package configuration and rejects unsupported compiler versions before running the export scanner.
• The onboarding guide now edits the generated example in place, documents the complete parameter and return surface, and explains warning and roxygen2 workflows.

rzig 0.2.0

Statistical interface breadth

• Integer, logical, and character vectors can be returned directly, decorated with attributes, and placed in generated lists.
• Ctx.rng() provides boundary-managed draws from R’s random-number stream, preserving set.seed() reproducibility on success and error paths.
• Rmath.normalCdf() and Rmath.normalQuantile() expose the linked R runtime’s normal distribution functions without consuming random state.

Boundary behavior

• User interrupts retain R’s interrupt condition class after Zig cleanup; ordinary error handlers and try() no longer swallow Ctrl-C.
• The POSIX integration gate sends a real SIGINT, checks the condition class, and verifies that the R session remains usable.
• The causal demonstration now returns a logical adjacency matrix and covers all three-variable orders plus a 12-variable search through depth five.

rzig 0.1.0

Package authoring

• use_rzig() scaffolds a portable Zig-backed R package, including generated registration, build configuration, and a working native example.
• document() derives R wrappers, exports, and documentation from plain Zig functions marked with /// @export.
• Generated packages build on Linux, macOS, and Windows with Zig 0.16.0 and R’s platform toolchain.

Native interface

• Typed conversions cover numeric, integer, logical, optional, string, vector, list, matrix, attributed, and explicitly mutable values.
• Mutable numeric inputs follow R copy-on-modify semantics by duplicating before Zig receives writable storage.
• Long computations can check R interrupts, and pure Zig indexed loops can use capability-restricted worker threads.

Reliability

• Native errors and ReleaseSafe panics become R conditions after Zig cleanup has completed.
• The boundary protects R allocations, keeps borrowed inputs read-only, and confines R API access to the calling thread.
• Cross-platform checks include hostile-input tests, garbage-collection stress, valgrind, native interface analysis, and reproducible boundary benchmarks.

Documentation

• Added a worked package tutorial and a vignette showing how to port an Rcpp hot loop while preserving copy-on-modify, error, and interrupt behavior.
