pakret vs rollupTree: at a glance
What is pakret?
Package citation for R documents, quietly growing to meet Quarto.
pakret inserts citations for R packages into R Markdown and Quarto documents, resolving each package to a BibTeX entry and writing the .bib file that backs it. Version 0.3.1 adds support for Quarto's inline syntax and separator control when citing several packages in one inline chunk, following 0.3.0, which made the package create missing .bib files, preserve capitalisation in reference titles, and treat the version placeholder in citation templates as optional. Cadence is a handful of small releases a year.
What is rollupTree?
The recursive-computation engine under massProps grows the accessors its consumer needed
rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.

Package citation for R documents, quietly growing to meet Quarto.
◆ Current state
pakret inserts citations for R packages into R Markdown and Quarto documents, resolving each package to a BibTeX entry and writing the .bib file that backs it. Version 0.3.1 adds support for Quarto's inline syntax and separator control when citing several packages in one inline chunk, following 0.3.0, which made the package create missing .bib files, preserve capitalisation in reference titles, and treat the version placeholder in citation templates as optional. Cadence is a handful of small releases a year.
◆ Where it's heading
Every release in this window removes a specific friction someone hit while writing a document. Bib files that had to exist beforehand now get created; single-letter package names like R and C stopped being lower-cased in titles; the package works when loaded after conflicted; citing many packages got faster; and version numbers became optional for documents where they are noise. The 0.3.1 Quarto support extends the same idea to the format its users are moving to. Nothing here is architectural, and nothing needs to be.
◆ Prediction
Expect continued alignment with Quarto as more of its syntax surfaces become relevant, and further refinement of how multi-reference packages resolve to a single entry, which the BibTeX type priority work in 0.2.0 started. The entries give no indication of a 1.0.

The recursive-computation engine under massProps grows the accessors its consumer needed
◆ Current state
rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.
◆ Where it's heading
The package develops in response to its one visible consumer. The 0.4.0 accessors appeared in January 2026 and massProps switched to them thirteen days later; 0.4.1 then fixed missing column names in the setters, which is the kind of defect only real use surfaces. Before that, 0.3.0's default_validate_dag() extended validation past strict trees to directed acyclic graphs, widening what structures the engine will accept.
◆ Prediction
On the established pattern the next release will be whatever massProps needs next, discovered by using it. A DAG validator suggests non-tree structures are in scope, but nothing in these notes says that path is being pushed further.
