Statement range provider does not work in Quarto's visual editor

System details:

Positron and OS details:

2025.05.0 (Universal) build 142

OS: Darwin arm64 24.4.0

Interpreter details:

R 4.5.0

Describe the issue:

Possibly related to closed issue #1646.

When you run code from a Quarto code chunk, hitting CMD + ENTER sends only the current line rather than the entire statement (when the statement is split on multiple lines). This is unrelated to CMD + SHIFT + ENTER which runs the entire code chunk.

Steps to reproduce the issue:

1. Create a Quarto document with R interpreter.
2. Create a code chunk.
3. Write several statements that span multiple lines.
4. Place cursor on first line of first statement.
5. Hit CMD + ENTER.
6. Only that line is sent to the console and an error comes up about an incomplete statement.

Expected or desired behavior:

The complete (multi-row) statement should be sent to the console and run.

Were there any error messages in the UI, Output panel, or Developer Tools console?

Error:
! 
Can't execute incomplete input:

Related to #1805

This is another example of a language feature (the statement range provider) that does not work in the Quarto visual editor.

In the short term, we could turn this off along with what we are turning off in #7201.

As a workaround for now, you could either avoid using the Cmd + Enter approach for other ones that work (like clicking the play button on the chunk) or edit the file in source mode.

After working on quarto-dev/quarto#710 I have realized we cannot turn this "off" because we aren't ever piping the statement range provider through to the visual editor at all. I think this should wait to go together with #1805, to turn on more LSP features in visual mode.

I'm really enjoying Positron, thanks for this great new IDE! I would suggest mentioning somewhere in docs, e.g. the FAQ, that some features users may expect for quarto work in source mode but not visual editing mode, e.g. chunk formatting with CMD+K CMD+F, and sending entire statements with CMD+Enter as noted here. It's not a big deal to switch back and forth between these modes, it's pretty snappy and just requires a file save.
