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 skytrackr?

Light-based animal geolocation gets a second model that stops assuming the bird sat still.

skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().

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.

Light-based animal geolocation gets a second model that stops assuming the bird sat still.

◆ Current state

skytrackr estimates animal positions from logger light data by fitting a sky-illuminance model. Three releases span the history: a 2023 v0.9 the author called functional but unpolished, a CRAN-compliant v1.0 in October 2025 that added batch reading and twilight screening, and a v2.0 six weeks later that is the first structural expansion. v2.0 pulls the data-selection and calibration steps out of the main skytrackr() call and exposes them as stk_filter(), stk_calibrate() and stk_center().

◆ Where it's heading

The arc is toward exposing internals the package used to hide. Each release takes a step that was buried inside the main fitting call and turns it into a function the researcher can inspect, plot and constrain, with the scale parameter now estimated across a whole dataset rather than guessed. The new individual light model is the sharper turn: it drops the stationarity assumption behind the original diurnal fit and solves each observation along a constant-bearing course from the previous position.

◆ Prediction

The author describes the individual model's robustness as still being evaluated and its convergence as more fickle than the diurnal approach, so the next release most likely tunes convergence and documents when each model applies rather than adding a third.
