What is lang?

R help pages translated on demand by whichever LLM you point it at.

lang translates R help documentation at read time using a language model of the user's choosing, rendering the result directly in the RStudio or Positron help pane rather than producing translated files. The two releases since launch have both targeted translation quality rather than reach: 0.1.1 added a context_size argument that summarizes the full help page and injects it into every field's prompt so terminology stays consistent across sections, and rewrote Rd parsing around a structured intermediate representation instead of regex. Version 0.1.2 then made that context conditional, omitting it for inputs of ten words or fewer.

What is logrx?

A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.

logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.

◆ Current state

lang translates R help documentation at read time using a language model of the user's choosing, rendering the result directly in the RStudio or Positron help pane rather than producing translated files. The two releases since launch have both targeted translation quality rather than reach: 0.1.1 added a context_size argument that summarizes the full help page and injects it into every field's prompt so terminology stays consistent across sections, and rewrote Rd parsing around a structured intermediate representation instead of regex. Version 0.1.2 then made that context conditional, omitting it for inputs of ten words or fewer.

◆ Where it's heading

The work is converging on the failure modes specific to running documentation translation through a model rather than a translation service. The Rd rewrite through rd_to_list() and list_to_rd() removes a class of formatting corruption that regex manipulation invited. The context-window tuning addresses the opposite problem — a local model handed a context summary longer than the field it is translating paraphrases the context instead. Both fixes are about making small, weaker, locally hosted models behave, which suggests that is the deployment the package expects.

◆ Prediction

Given that both post-launch releases tune prompt construction for local models, expect further per-field prompt heuristics rather than new output targets.

0.0

A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.

◆ Current state

logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.

◆ Where it's heading

Feature work concentrated in the 0.1 line — return codes, a results writer, a to_report parameter, and logging of unapproved package and function use — and the 0.2 releases have been compatibility maintenance and hotfixes. Three years of silence in a pharmaverse that has otherwise kept shipping suggests the package reached the shape its users needed rather than that it was abandoned mid-design.

◆ Prediction

Nothing in these entries points to planned work; the likeliest trigger for a release is a breaking change in tidyverse dependencies, which is what produced the last one.
