chromer vs lang: at a glance
What is chromer?
A chromosome-count database client that only ever ships when the upstream API moves.
chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.
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.

◆ Current state
chromer is a thin R client for the Chromosome Counts Database. Every release in the past three years is maintenance: a new maintainer and licence change in 0.3, test-skipping when the upstream service is down in 0.4, and two separate releases whose entire content is that the database's URL changed again. The current 0.10 points at ccdb.tau.ac.il/services/.
◆ Where it's heading
The package is functionally complete and externally driven — its release cadence is a record of the CCDB's hosting history rather than of any development plan. The defensive work in 0.4, which added an internal check for whether the database is down and skips tests accordingly, shows the maintainer treating upstream instability as the permanent condition rather than an incident.
◆ Prediction
The next release will most likely be triggered by another CCDB endpoint or format change; nothing in the history suggests new functionality is planned.

◆ 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.
