Multi-line Julia Code

[BradyAJohnston]

When working in VSCode, multi-line code runs if you run the whole cell, but if the code is split over multiple lines and you use the CMD + Enter / Ctrl + Enter to run a single-line, it only attempts to run the one line and breaks.

With the chunk below, hitting Ctrl+Enter on the first line:

randn(
    10
)

Results in this error:

julia> randn(
ERROR: syntax: incomplete: premature end of input
Stacktrace:
 [1] top-level scope
   @ code:1

Multi-line but not whole-chunk execution would be very handy. Thanks for the great plugin so far though!

I believe this problem also occurs outside of Julia.
I was editing R the other day and needed to run it in code block units.

Yes in both cases the plugin doesn't have the syntactic awareness to run the next statement (only lines). I believe in the case of R the interpreter will prompt for the next line but in Julia is yields an error.

I can't verify, but it might be fixed (I am not 100% sure of it based on how Julia code is evaluated) thanks to 0ac9f340a5cf1b9af10aecc097601fb27a98f034 released in v1.54.0.

No, this doesn't yet work for Julia. I tried to make it work by executing the language-julia.executeCodeBlockOrSelectionAndMove command from the Julia extension, however an error occurred (it may be that it didn't like that qmd rather that jl was where the command was executed from)

I asked a similar question in Quarto CLI: quarto-dev/quarto-cli#3679

This happens in Python as well. Do we have a solution to execute multiline statement like in RStudio?

[jjallaire]

This should work now for R.

For Python and Julia, we need the native extensions to provide a command or API that implements this. Julia appears to have one in the language-julia.executeCodeBlockOrSelectionAndMove command, but it doesn't seem to work for qmd files.

For Python there is a new extension that provides some functionality along these lines: https://github.com/kylebarron/vscode-jupyter-python/blob/1f3a196dffd8ecd746dada7cbdc71be9716aded3/src/run-code.ts#L41

[jjallaire]

From looking at the source code it appears as if this should work with qmd files w/o any special configuration. Have you found that to be the case? This also might be something we could incorporate directly into the quarto extension (as things stand now the keyboard shortcuts conflict by default so it might be more straightforward if we defined/implement this internally in a similar fashion).
