What is parzer?

A coordinate parser whose entire job is surviving how badly humans write latitude and longitude.

parzer converts messy coordinate strings — degrees, minutes, seconds, assorted symbols, arbitrary whitespace — into decimal degrees. Development is slow and sporadic, with three-year gaps between releases, and the work splits between C++ performance in the internal scrub() path and a long tail of parsing bugs. The most recent release, 0.4.4, fixed two genuinely dangerous ones: a leading space could silently drop a negative sign, and an E in a longitude string returned NA while a W parsed fine.

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.

A coordinate parser whose entire job is surviving how badly humans write latitude and longitude.

◆ Current state

parzer converts messy coordinate strings — degrees, minutes, seconds, assorted symbols, arbitrary whitespace — into decimal degrees. Development is slow and sporadic, with three-year gaps between releases, and the work splits between C++ performance in the internal scrub() path and a long tail of parsing bugs. The most recent release, 0.4.4, fixed two genuinely dangerous ones: a leading space could silently drop a negative sign, and an E in a longitude string returned NA while a W parsed fine.

◆ Where it's heading

The package has settled its scope — 0.4.1 explicitly rewrote the documentation to say it parses coordinates rather than validates them — and now moves only when someone finds a string it mishandles. Recent work has also been about shedding weight: Rcpp dependence reduced, the C++ requirement dropped from DESCRIPTION, suggested dependencies removed, and the vignette builder moved to Quarto. Maintainership passed to a new maintainer in 2022 and the package has stayed within rOpenSci.

◆ Prediction

The next release will most likely be another batch of parsing edge cases reported by users, since that is what every release since 0.2.0 has been. Nothing in these entries points to new functionality.

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.
