What is gMCPLite?

gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.

gMCPLite is a fork of gMCP with the Java dependency removed and `hGraph()` ported over from gsDesign, giving R users graphical multiple comparison procedures and their visualisation without a JVM. Since that fork, no release has added a statistical capability. The visible history is compatibility work: ggplot2 3.5.0 argument naming, a cairo device for Unicode in examples, testthat 3.3.0 snapshot requirements, and a selective port of an upstream confidence-interval fix.

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.

gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.

◆ Current state

gMCPLite is a fork of gMCP with the Java dependency removed and `hGraph()` ported over from gsDesign, giving R users graphical multiple comparison procedures and their visualisation without a JVM. Since that fork, no release has added a statistical capability. The visible history is compatibility work: ggplot2 3.5.0 argument naming, a cairo device for Unicode in examples, testthat 3.3.0 snapshot requirements, and a selective port of an upstream confidence-interval fix.

◆ Where it's heading

This is a package with a fixed job. The maintainers track two moving targets — the upstream gMCP it forked from, and the R graphics and testing stack underneath it — and pull across only what is needed. The addition of vdiffr visual regression tests for `hGraph()` is the most substantive recent change and fits the same posture: the plots are the deliverable, so pin them against accidental drift rather than redesign them.

◆ Prediction

Expect the pattern to continue — compatibility releases driven by ggplot2, testthat and pkgdown changes, with any statistical content arriving only as a selective port from upstream gMCP.

0.0

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.
