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 nanonext?

nanonext keeps shrinking its build requirements while adding messaging primitives.

The R binding to NNG ships roughly monthly. Since February the package added an HTTP server that can run synchronously or through the later event loop, a zero-copy device forwarder for building brokers and proxies, and support for pthread-enabled WebAssembly targets. Send operations now move the buffer straight into the NNG message, halving peak memory on serialized sends.

◆ 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.

nanonext keeps shrinking its build requirements while adding messaging primitives.

◆ Current state

The R binding to NNG ships roughly monthly. Since February the package added an HTTP server that can run synchronously or through the later event loop, a zero-copy device forwarder for building brokers and proxies, and support for pthread-enabled WebAssembly targets. Send operations now move the buffer straight into the NNG message, halving peak memory on serialized sends.

◆ Where it's heading

Two directions run in parallel. One is making the package installable anywhere — the build-time cmake dependency is gone, so compiling bundled NNG and Mbed TLS needs only a C compiler, and WebAssembly targets are supported. The other is raising the ceiling on what can be built on top: device_aio() for message forwarding, an HTTP and WebSocket server with a content map, and stream buffer control. Bug fixes in recent releases concentrate on memory safety in the bundled C sources.

◆ Prediction

Given the pace and the tight coupling declared in each release, expect the next version to track a mirai requirement and continue hardening the HTTP server paths that the last two releases have been leaking memory in.
