What is quarto?

Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.

This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.

What is watcher?

watcher is a thin filesystem-events binding whose releases are mostly build work.

The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

Quarto's editor extension is quietly becoming Positron-first while keeping VS Code parity.

◆ Current state

This is the Quarto extension for VS Code and Positron — cell execution, preview and render, the visual editor, snippets, and the language-server plumbing that makes .qmd files behave like real code documents. The last several releases have pushed the editing experience toward parity with ordinary source files: diagnostics inside code cells, code symbols and cells in the outline, semantic highlighting, and clickable file links with autocompletion in _quarto.yml. A large share of every release is now Positron-specific work rather than generic VS Code support.

◆ Where it's heading

Two patterns hold across releases. First, Positron is where new surface appears first — notebook editor commands, statement execution, runtime-aware language selection for new cells, and a bundled-CLI preference setting all landed as Positron features. Second, the extension is steadily stepping back from things dedicated tooling does better, giving up .typ files to Typst extensions and commenting out IPython magics in the virtual document so Ruff and Pyrefly stop flagging them. The multi-language story keeps widening, with Julia cells joining Python and R for in-editor execution.

◆ Prediction

Given how much recent work has been notebook-editor commands and .ipynb conversion, expect further consolidation of the notebook and .qmd paths behind shared commands rather than new authoring features.

watcher is a thin filesystem-events binding whose releases are mostly build work.

◆ Current state

The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

◆ Where it's heading

The API is deliberately small and appears finished; the work that remains is making the C dependency install cleanly everywhere. Dropping cmake follows the same move nanonext made, which is not a coincidence — both come from the same author and both are aiming at environments where installing a build system is not an option.

◆ Prediction

With cmake gone and the bundled library current, further releases are most likely to track libfswatch upstream rather than extend the R interface.
