What is datefixR?

The messy-date parser rewrote its core in Rust and came out 300x faster.

datefixR standardizes inconsistently formatted dates — the kind that arrive from spreadsheets and hand-entered clinical or survey data, with mixed separators, ambiguous orders, missing components, and month names in whatever language the source used. Version 2.0.0 rewrote the parsing core in Rust, reporting over 300x throughput against previous versions through fastpath handling of common formats and parallel column processing via a cores argument. Version 2.0.1 then spent itself cleaning up after that rewrite, restoring ordinal indicator support, stopping malformed dates from being silently cast to NA, and reinstating error messages that had gone missing.

What is pkglite?

pkglite's whole job is knowing which files in an R package are text — and it keeps getting better at guessing.

pkglite packs an R package into a single plain-text file and unpacks it again, the mechanism pharmaceutical submissions use to move source through systems that accept text but not archives. The API settled at 0.2.0 with file specification templates, `merge()` and `prune()`. Every release since has improved the same thing: the dictionary that decides whether a file is text or binary, most recently rebuilt from the file extensions found across 21,369 CRAN packages.

The messy-date parser rewrote its core in Rust and came out 300x faster.

◆ Current state

datefixR standardizes inconsistently formatted dates — the kind that arrive from spreadsheets and hand-entered clinical or survey data, with mixed separators, ambiguous orders, missing components, and month names in whatever language the source used. Version 2.0.0 rewrote the parsing core in Rust, reporting over 300x throughput against previous versions through fastpath handling of common formats and parallel column processing via a cores argument. Version 2.0.1 then spent itself cleaning up after that rewrite, restoring ordinal indicator support, stopping malformed dates from being silently cast to NA, and reinstating error messages that had gone missing.

◆ Where it's heading

Two long arcs meet here. The first is localization: Russian, Indonesian, German, Spanish month abbreviations, and experimental Roman numeral months accumulated release by release, with full translation of user-facing messages treated as a goal rather than a bonus. The second is the migration off R for the parsing hot path — internals began moving to C++ around 1.3.1 before the Rust rewrite replaced that work entirely. The 2.0.1 regressions show the cost of that move, since behavior that was implicit in the R implementation had to be re-specified.

◆ Prediction

The Rust core is one release into stabilization and 2.0.1 was entirely regression repair, so expect further correctness fixes against pre-2.0.0 behavior before any new format support lands.

pkglite's whole job is knowing which files in an R package are text — and it keeps getting better at guessing.

◆ Current state

pkglite packs an R package into a single plain-text file and unpacks it again, the mechanism pharmaceutical submissions use to move source through systems that accept text but not archives. The API settled at 0.2.0 with file specification templates, `merge()` and `prune()`. Every release since has improved the same thing: the dictionary that decides whether a file is text or binary, most recently rebuilt from the file extensions found across 21,369 CRAN packages.

◆ Where it's heading

The failure mode this package cares about is silent — misclassify a binary file as text and the round trip corrupts it, misclassify text as binary and it bloats or drops. So the work is empirical rather than architectural: mine real packages for what extensions actually appear, then widen coverage where specific ecosystems break the pattern. Stan interfaces via rstan brought `src/Makevars` and `src/Makefile` handling; machine learning frameworks brought their own binary formats. Dependencies have gone the other way, with cli removed and replaced by internal equivalents.

◆ Prediction

Expect the next substantive release to widen file specification coverage again for whatever package family the maintainers find breaking the default discovery, since that has been the content of every non-maintenance release for four years.
