nuggets vs whirl: at a glance
What is nuggets?
nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.
nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.
What is whirl?
whirl turned script logging into a standardized provenance artifact regulators can read.
A parallel R script runner that produces execution logs, aimed at regulated analysis environments. The 0.3.0 release added write_biocompute(), emitting logs as BioCompute Objects in standardized JSON, and simplified the approved-package check to a plain package@version vector. Since then the work has been about what the log can be trusted to contain: an environment_secrets option to keep secret variables out of it, direct versus indirect package usage distinguished and highlighted against the approved list, and the same approval check extended to Python packages.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.
◆ Current state
nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.
◆ Where it's heading
Two forces are shaping the package. One is coverage: baseline, complement and paired-baseline contrasts, correlations, tautologies, ancestors and clustering have all been added as first-class dig_ or explore_ surfaces, so the same search engine now answers a widening set of questions. The other is weight — Shiny packages moved from Imports to Suggests, BH and RcppThread dropped, XSIMD updated, parse_condition() rewritten in C++ — which keeps a package with an interactive app from forcing that app's dependencies on every user. Deprecations are handled through lifecycle rather than removed abruptly.
◆ Prediction
Expect the sparse-data optimisation to extend from crisp to fuzzy data, and explore() to keep gaining tabs as each new pattern family lands, on the roughly six-week cadence the 2.2 line has held.
whirl
0.0INFRA · APIS
whirl turned script logging into a standardized provenance artifact regulators can read.
◆ Current state
A parallel R script runner that produces execution logs, aimed at regulated analysis environments. The 0.3.0 release added write_biocompute(), emitting logs as BioCompute Objects in standardized JSON, and simplified the approved-package check to a plain package@version vector. Since then the work has been about what the log can be trusted to contain: an environment_secrets option to keep secret variables out of it, direct versus indirect package usage distinguished and highlighted against the approved list, and the same approval check extended to Python packages.
◆ Where it's heading
The through-line is the log as evidence rather than as debugging output. Every recent addition either widens what the log proves — which packages were really used, in which language, against which approved list — or narrows what it must not leak. Setting options only through an explicit with_options argument to run() and getting renv library paths right for Quarto both point the same way: reproducible, auditable child sessions with nothing implicit.
◆ Prediction
Expect the approved-package and provenance machinery to keep expanding across languages and environments, since Python approval checks followed the R ones and both feed the same log.
