eitsupi @eitsupi.bsky.social · 08/10/2026I have released version 0.6.0 of #rstats arf console. This version includes significant improvements to the help viewer. - We can move the links. - An experimental option allows us to use the arf help viewer instead of pager. 030
Reposted by eitsupiCharlie Gao @shikokuchuo.net · 03/10/2026TokyoR enjoyed the world premiere of mizu today, and Mizu-chan stole the show: lock-free shared-memory parallelism for R, plus a Python binding on the same C core. Repos are open but pre-release, and the API will change. Feedback welcome on GitHub. github.com/shikokuchuo/... #RStats #Tidyverse 2227
Reposted by eitsupiCharlie Gao @shikokuchuo.net · 03/10/2026本日の #TokyoR で、mizu のワールドプレミアをお届けしました！主役はミズちゃん💧 mizu は、ロックフリーな共有メモリで、同じマシン上のRプロセス同士をつなぐパッケージです。同じCコアのPython版 pymizu もあるので、RとPythonでチャネルを共有できます。 プレリリースなのでAPIは変わるかもしれません。ぜひ試して、感想はGitHubへ！ github.com/shikokuchuo/... 194

eitsupi @eitsupi.bsky.social · 06/09/2026Wow, thank you so much! I was actually a sponsor of yours until a few months ago (knitr helped me a lot!), and I never imagined the sponsorship would come full circle like this. :) 130
eitsupi @eitsupi.bsky.social · 20/08/2026I also want to highlight @jolars.co 's excellent arity project. Its Rust parser and formatter made working with R source code much easier and was an important foundation for mini-roxygen. github.com/jolars/aritygithub.comGitHub - jolars/arity: Language server, formatter, and linter for RLanguage server, formatter, and linter for R.

eitsupi @eitsupi.bsky.social · 20/08/2026For most R package developers, roxygen2 will probably remain the best choice. But for packages with expensive native builds, such as r-polars I maintain, replacing roxygen2 with mini-roxygen may improve the development experience by avoiding a full compile just to regenerate documentation. 110

eitsupi @eitsupi.bsky.social · 06/02/2026There are also numerous other improvements, including a history backup feature and documentation to help with migration from radian. 000
eitsupi @eitsupi.bsky.social · 06/02/2026It was a particularly noteworthy improvement that pasting multiple lines now works perfectly on Windows, because this was made possible by fixing a bug that had been left unfixed for years in crossterm! github.com/crossterm-rs...

eitsupi @eitsupi.bsky.social · 06/02/2026I have released version 0.2.0 of #rstats arf console.

eitsupi @eitsupi.bsky.social · 04/02/2026Can you check the R path with the :info meta command? It's possible that you're using the other R than the one installed by r2u (i.e., is rig not installed?). Please specify the R path you want to use in your configuration file. 000
eitsupi @eitsupi.bsky.social · 01/02/2026For example, when trying to initialize R on Windows, I was instructed to try all three methods (radian, sircon, and ark), and in the end only the ark method worked, so there was a lot of trial and error, but I don't understand the details myself. What's amazing is the ingenuity of our predecessors. 020
eitsupi @eitsupi.bsky.social · 01/02/2026Actually, my Rust skills are not that great. Most of the code for arf was written by Opus 4.5, and I only instructed them to refer to the source code of sircon, etc. (I was also in charge of manual testing.) 110
eitsupi @eitsupi.bsky.social · 01/02/2026The installation size has become slightly smaller (9MB v.s. 11MB now), and I confirmed during development that startup times are faster. As mentioned on mstdn, this is probably due to the fast drawing speed of Rust, so drawing may be faster than in the regular R console. 020
Reposted by eitsupiGrant McDermott @gmcd.bsky.social · 31/01/2026#rstats I've been testing out `arf`, a new R console written in Rust. Early days, but a v. smooth experience so far. Much simpler to install and link from VS Code than radian, for example, with better features too. github.com/eitsupi/arfgithub.comGitHub - eitsupi/arf: Alternative R Frontend — a modern R console written in RustAlternative R Frontend — a modern R console written in Rust - eitsupi/arf 54210
eitsupi @eitsupi.bsky.social · 01/02/2026I don't think I could have done this kind of software without AI, so I have a lot of respect for what was written by hand, but times seem to have changed, for better or worse. 240
eitsupi @eitsupi.bsky.social · 01/02/2026In fact, the existence of sircon convinced me that this was technically possible, and I've been thinking about making it someday. I've never installed sircon, but after having Claude Code look at it, I was impressed by how incredibly advanced its functionality is. 120
