The recursive-computation engine under massProps grows the accessors its consumer needed
A side-by-side editorial comparison of LightLogR and tabular — release velocity, themes, recent moves, and the top alternatives to consider.
Wearable light-exposure data gets circular time and versioned device formats
LightLogR ingests recordings from wearable light loggers and optical radiation dosimeters, and its release notes are lopsided: four of the six most recent tags are one-line merge stubs while 0.10.0 carries several thousand words. That release is where the package sits — dataset-wide summary tables, a version argument on the importers, and time of day handled as a circular quantity.
tabular went from clinical tables to complete TFL output in under two months.
tabular renders pre-summarised clinical tables, figures and listings to RTF, LaTeX, HTML, PDF, DOCX, Markdown and now Typst from one immutable verb pipeline, with no external SAS or Java runtime. It arrived in June 2026 as a CRAN submission candidate, added figure() a month later to cover the F in TFL, and has spent the 0.3.x line on speed, font resolution and toolchain diagnostics.

The arc runs from reading files off N devices toward modelling the awkward shapes of chronobiology data. Circular conversion lets bedtimes crossing midnight average correctly; remove_partial_data() can demand a minimum duration rather than a fraction of a known total; add_states() takes Interval objects so sleep-scoring output flows straight in. The device side hardens in parallel — supported_versions() exists because a VEET firmware release changed the file format mid-life.
The version switch currently covers VEET and a German-locale Actiwatch Spectrum; more device-format generations behind that same argument are the obvious continuation as manufacturers revise exports. The named milestones (Civil Dawn, then Sunrise) suggest the next substantive release will be another themed one rather than a steady drip.

The work is converging on backend parity — one spec should render the same wherever you emit it. Recent notes are almost entirely gap-closing between targets: bold column headers and page-width correction on LaTeX, cell margins on DOCX, group-separator blank rows re-expressed as discardable space so a page never ends on a stray gap, whitespace collapsing honoured on Typst. Diagnostics are keeping pace, with check_latex() probing through kpsewhich and check_typst() auditing the compiler and font chain.
With both toolchain checkers in place, the friction that remains is environmental rather than featural, and the notes point to further parity and packaging fixes rather than another backend. Whether Typst becomes the default PDF path instead of LaTeX is not something these notes settle.
