send to console does not work

[hutch3232]

Description

A common work flow I have is to open a .py file, then create a console for it. I'll then interactively work, running line by line by sending to console with shift+enter. I am finding that in certain (common) situations some lines won't send to console.

I have found two work arounds:

• highlight the entire row then shift+enter
• put the cursor at the very initial position of the line, then shift+enter

Reproduce

1. Open a new .py file
2. right-click on it and select "create console for editor"
3. Create the following script

12
1

Sending the first line will work. Update to:

123
1

Now the first line will not send.
Update to:

123
12

Now the first line will send again.
Update to:

1234
12
12

This will send, but it positions you between the first and second character of line 3.
(This assumes you're placing the cursor at the right-end of the line in these tests).
It seems if the cursor position is greater than the length of subsequent lines (combined?) it will send, but it jumps to a line-length dependent position (not always to the end of the line).

Expected behavior

The sending of code should not be line-length dependent. It should send and jump your cursor to the next line of code (and be positioned at the same relative position (beginning or end of line).

Context

• Operating System and version: Linux Ubuntu 20.04
• Browser and version: Chrome 123
• JupyterLab version: I have tried 4.0.9, 4.1.5, 4.1.6, and 4.1.8
  • This does not happen prior to 4.0.0 (or at least not 3.6.6 which I previously used)

I can provide the troubleshoot and command line output, if needed, but the "out of range" error seen in the browser output seems to me that it might be sufficient info.

Troubleshoot Output

Paste the output from running `jupyter troubleshoot` from the command line here.
You may want to sanitize the paths in the output.

Command Line Output

Paste the output from your command line running `jupyter lab` here, use `--debug` if possible.

I run into very similar issue. I was able to run a single selected line by putting the cursor at the beginning of the line.

After upgrading to 4.2.0, The shortcut "Shift+Enter" does not work anymore, no matter how I place the cursor. But if I use click the "Run selected code" in the "run" menu, the line successfully runs on the console. I guess it is an issue related to keyboard shortcut.
