What is ore?

A stable Oniguruma binding for R that ships correctness fixes and little else.

ore wraps the Oniguruma regex engine for R, and its recent history is entirely about making that binding safe rather than richer. The last three releases fix an infinite-loop hazard on zero-length matches, a named-group propagation bug, and locale detection at startup. The user-facing API has not moved since 1.7.1, when ore_file() began recording whether a file was read as binary.

What is rwasm?

The toolchain that gets R packages into the browser is optimising for payload size, not features.

rwasm cross-compiles R packages to WebAssembly and assembles the virtual filesystem images that webR loads. Its three releases have moved from making cross-compilation work at all — Autoconf overrides, uname and pkg-config shims, OpenMP support — to controlling how the resulting artefacts are packaged and shipped. Every release is pinned to a specific webR version floor.

0.0

A stable Oniguruma binding for R that ships correctness fixes and little else.

◆ Current state

ore wraps the Oniguruma regex engine for R, and its recent history is entirely about making that binding safe rather than richer. The last three releases fix an infinite-loop hazard on zero-length matches, a named-group propagation bug, and locale detection at startup. The user-facing API has not moved since 1.7.1, when ore_file() began recording whether a file was read as binary.

◆ Where it's heading

This is a package in maintenance, not development. The changes cluster around C-level hygiene — memory leaks, buffer overruns, sprintf() removal, compiler warnings — which reads as keeping CRAN checks green rather than pursuing new capability. Releases arrive in pairs separated by minutes or in gaps of two years, a cadence typical of a package touched only when something breaks or a CRAN policy shifts.

◆ Prediction

The next release is most likely another correctness or toolchain fix rather than new regex functionality; the README's note about CRAN and mainline diverging suggests the two versions may be reconciled at some point, though the entries do not say when.

The toolchain that gets R packages into the browser is optimising for payload size, not features.

◆ Current state

rwasm cross-compiles R packages to WebAssembly and assembles the virtual filesystem images that webR loads. Its three releases have moved from making cross-compilation work at all — Autoconf overrides, uname and pkg-config shims, OpenMP support — to controlling how the resulting artefacts are packaged and shipped. Every release is pinned to a specific webR version floor.

◆ Where it's heading

The arc runs from correctness to delivery. The first release fought the cross-compilation environment itself, isolating builds from host libraries and shimming the tools configure scripts expect. The second replaced Emscripten's own file_packager with a custom metadata path and added gzip compression for filesystem images. The third is pure coordination, rebuilding the build system for webR 0.5.0. That cadence — roughly annual, each release gated on a webR version — makes this a component of the webR release train rather than an independently moving project.

◆ Prediction

The next release will most likely follow the next webR version, since two of three releases so far have been driven by a webR floor rather than by rwasm's own agenda.
