#rstats tidypolars 0.18.0 is available!

tidypolars provides the tidyverse syntax while using polars for better performance.

In this release:
- support more base R functions
- bug fixes (including better NA handling in several functions)
- and more

Changelog: https://www.tidypolars.etiennebacher.com/news/

@GillesColling@fosstodon.org no particular handling of tidyeval for now but I haven't come across false positives because of this. Feel free to open an issue if you have some examples, that would be very helpful. There are several other packages that come with their own syntaxes (like box, igraph) so it's just a problem that is very hard to solve with static analysis

@bentoh@mastodon.online happy to read that! But Jarl is a replacement for lintr rather than Air, so you can pair Jarl and Air in precommit. See this page: https://jarl.etiennebacher.com/howto/precommit

#rstats I'm very happy to announce Jarl 0.5.0!

Jarl is a very fast R linter, written in Rust. This release brings many improvements and fixes:

- check R code chunks in R Markdown and Quarto docs
- check "@examples" and "@examplesIf" sections if you use roxygen2
- detect unused or duplicated functions in pkgs
- rules on specific pkgs, e.g. on `dplyr::filter()`, are now possible. Feel free to suggest more and in other pkgs too!

@maelle@mastodon.social ah merci ! J'avais juste copié le texte du post bluesky

#rstats I'm very happy to announce Jarl 0.4.0!

Jarl is a very fast R linter, written in Rust. This release brings lots of improvements and fixes:

- Jarl can now find unreachable code, meaning code that will never run because it's after a stop(), a return(), etc.
- the suppression comments system (to ignore diagnostics on specific lines) has been entirely rewritten
- and more!

See the blog post: https://www.etiennebacher.com/posts/2026-02-03-jarl-0.4.0

#rstats I've given a workshop a few days ago on handling large data (think tens to hundreds of millions of rows) with Polars in Python and in R.

Here are my introductory slides: https://brussels-large-data-r-python.etiennebacher.com

@schuemaa@ecoevo.social good question, I have never used emacs myself so I don't have the answer, but if you find a way please let me know: https://github.com/etiennebacher/jarl/issues/138

#rstats I'm very happy to introduce Jarl, a new R linter.

Jarl is a command line tool with extensions in VS Code, Positron, and Zed. It is extremely fast, able to check thousands of lines of R code in milliseconds. The GIF below shows how r-source (about 200k lines of R code) is parsed in less than 800ms.

Jarl provides several output formats, a workflow file for Github Actions, and more features.

@ginolhac@fosstodon.org @LeafyEricScott@fosstodon.org I do hope that tidypolars is useful to some people, but honestly I can't compete with the manpower dedicated to duckplyr. I also have less usecases for tidypolars as I'm now looking for a job. (That said I still gladly accept bug reports and feature requests in tidypolars :) )

@atsyplenkov@fosstodon.org Nice, I will try this!

#rstats {flint} 0.1.2 is available via R-universe! This release comes with several bug fixes and new linters.

{flint} is a package to detect and automatically fix lints in R code. It is also very fast and compatible with many {lintr} rules.
