Getting completions for the df variable in the R code block works:

Tested using a macOS temp build https://github.com/posit-dev/positron-builds/actions/runs/13505873706

I just downloaded the installer from https://github.com/posit-dev/positron-builds/actions/runs/13505873706 but don't see the updated Quarto:

And I still don't see any completions in Python chunks in a .qmd file.

Let me try making a local release build.

Doing a local release build, I see:

[17:00:53] Fetch completed: Status 200. Took 5027 ms

But then I still saw Quarto 1.6.40 when I opened the local release build of Positron and that's when I realized that I must have installed Quarto myself, and Positron prefers that one to our bundled Quarto.

After I did sudo rm -rf /Applications/quarto then I saw 1.6.42 in Positron. ✅

However, I still don't see any Python completions in a .qmd file:

I see completions for:

• Python code in the console
• R chunks in a .qmd

but still not the ones originally reported in #6444, similar to #6444 (comment) who says they installed Quarto 1.6.42.

Might I still be missing something, similar to how I had to uninstall my non-bundled Quarto installations?

[juliasilge]

I don't think this was ever a problem for R; I can get R completions fine in Positron with Quarto 1.6.40. Maybe entirely unrelated to rstudio/rstudio#15737?

[juliasilge]

I don't think this fix applies to us; see my notes in #6444 (comment).

Ok, we'll need to track down what happened around the time of the 1.96 upstream merge
