@masalmon.eu has written up a great post on the downstream effects of tree-sitter-r!

- Air, for formatting
- Jarl, for linting
- Positron's R support, for completions and more
- GitHub Search for R

It's been very cool to see all the ways this one project has been used to enhance #rstats!

A screenshot of the Remote Explorer pane in Positron where you can see "Dev Containers" is now listed in the drop down options. There is text overlaid that says "Look! now you can choose containers if you open a project with one!"

DID YOU KNOW that experimental support for #devcontainers was added to #Positron all sneaky-like in December?

Glad I was made aware of this, I already have a working VSCode/Positron extension specific to {targets} so I can perform static analysis, navigate, debug, add static pipeline autocomplete, and generally make sense of my giant targets pipelines much more easily🥳

A list table is a fenced div with the .list-table class containing a bullet list. Each top-level bullet represents a row, and nested bullets represent cells:

::: {.list-table}
- - Fruit
  - Price

- - Apple
  - 1.20

- - Orange
  - 0.90

Positron Positron unifies exploration and production work in one free, AI-assisted environment, empowering the full spectrum of data science in Python and R.

In the age of AI-driven programming, IDEs are still essential for an excellent coding journey. My favorites are Zed (zed.dev) for software development and Positron (positron.posit.co) for data science, especially for interactive exploration. #Coding #DataScience
