lang vs typst-gather
A side-by-side editorial comparison of lang and typst-gather — release velocity, themes, recent moves, and the top alternatives to consider.
lang vs typst-gather: at a glance
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 typst-gather?
Extracted from Quarto's CLI, typst-gather learned to explain a dependency tree before fetching it.
typst-gather collects Typst packages into a local cache so documents build offline and hermetically. It was extracted from quarto-cli and reached CRAN-equivalent shape in three releases over a single day, then added an `analyze` subcommand that walks `@Preview` and `@Local` imports — following transitive dependencies of local packages — and prints structured JSON without downloading or copying anything.

◆ 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.
typst-gather
0.0ANALYTICS
Extracted from Quarto's CLI, typst-gather learned to explain a dependency tree before fetching it.
◆ Current state
typst-gather collects Typst packages into a local cache so documents build offline and hermetically. It was extracted from quarto-cli and reached CRAN-equivalent shape in three releases over a single day, then added an `analyze` subcommand that walks `@Preview` and `@Local` imports — following transitive dependencies of local packages — and prints structured JSON without downloading or copying anything.
◆ Where it's heading
The 0.2.0 restructuring is the tell: subcommands with backwards compatibility, config readable from stdin, and every diagnostic message moved to stderr so stdout carries nothing but JSON. Those are the conventions of a tool meant to be called by another program, not typed by a person. Given its origin inside Quarto's toolchain, the plausible consumer is a build system that needs to know a document's package requirements before deciding what to fetch.
◆ Prediction
The analyze path currently reports imports; the natural extension visible from here is acting on that report — lockfile output or verification that a cache satisfies a document's dependency set — though the entries do not commit to either.

ymlthis
ymlthis retired itself, naming Quarto as the reason it no longer needs to exist.
forestly
forestly built an interactive safety review tool, then taught it to produce submission-ready RTF.
pharmaverseadam
pharmaverseadam is the pharmaverse's test-data mirror, and it now covers neurology.
pkglite
pkglite's whole job is knowing which files in an R package are text — and it keeps getting better at guessing.
gMCPLite
gMCPLite exists to be gMCP without Java, and its releases guard that boundary rather than extend it.
