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.
