Terminal escape sequences shown when running code

[MaxPowerWasTaken]

Type: Bug

I have the following code in my main.py:

import pymupdf

print(f"pymupdf version is: {pymupdf.__version__}")

I can create a python3.12 environment with pymupdf installed and run it from my (kubuntu24.04) shell without issues, with the following commands (showing shell log after each >command):

>uv --version
uv 0.4.17

>uv init --no-pin-python
Initialized project `askliz2`

>uv venv --python 3.12.6 
Using CPython 3.12.6
Creating virtual environment at: .venv
Activate with: source .venv/bin/activate

>source .venv/bin/activate 
askliz2>uv add pymupdf 
Resolved 3 packages in 281ms
Installed 2 packages in 11ms
 + pymupdf==1.24.10
 + pymupdfb==1.24.10

askliz2>python main.py
pymupdf version is: 1.24.10

However, when I launch vscode from this folder with my uv venv activated with code ., and then highlight the line import pymupdf and hit shift+enter to run it in the integrated terminal, I get the following vscode integrated terminal output:

/home/max/askliz2/.venv/bin/python 
Python 3.12.6 (main, Sep  9 2024, 22:11:19) [Clang 18.1.8 ] on linux

]633;E;import pymupdf]633;D;0]633;A>>> ]633;B]633;C

Things I've tried so far:

• upgrading uv version
• hosing and re-installing vscode
• installing different python versions (e.g. 3.12.0, 3.12.6, 3.9)
• right-clicking to clear terminal and kill terminal and then trying again

When I use the command pallet to select python interpreter, it shows me it's trying to use Python 3.12.6('.venv') ./.venv/bin/python, as it should be, and as the vscode integrated logs above already indicate.

@Tyriar This looks like a terminal bug.

[MaxPowerWasTaken]

hey, sorry to be persistent, but any idea how I might fix or get around this? I'd really love to use vscode with uv...

[MaxPowerWasTaken]

hello @karthiknadig or @Tyriar , any ideas on how I might resolve this? Just tried again on a fresh repo with a fresh install of vscode last night after a month, still hitting the same issue though.

[karthiknadig]

@MaxPowerWasTaken Try toggling this setting as a potential workaround. You will have to re-open the terminal:

[MaxPowerWasTaken]

thanks for the suggestion @karthiknadig . I toggled that setting from checked to unchecked, then restarted vscode but still am having the same problem.

this time higlighted and hit shift+enter on the following two lines:

def main():
    print("Hello from hello.py!")

and observed the following in my integrated terminal:

 ~/uv/askliz_frontend  main ?6  /home/max/uv_test/askliz_frontend/.venv/bin/python
Python 3.12.6 (main, Sep  9 2024, 22:11:19) [Clang 18.1.8 ] on linux

Turn off python.terminal.shellIntegration.enabled doesn't work.

[vs-code-engineering]

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.95.3. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

[Tyriar]

This is definitely related to the python shell integration script. I don't think this happens anymore though as it's disabled in Windows for now.

[MaxPowerWasTaken]

Hi @Tyriar, I observed this issue on my ubuntu24.04 laptop (not linux as in windows/wsl). Should it still be closed already, even if it should be resolved on windows machines?

[Tyriar]

@MaxPowerWasTaken thanks for the clarification, I missed that. Reopening for @anthonykim1 to consider.

[anthonykim1]

Can @MaxPowerWasTaken @nuzar update the Python extension to lastest and make sure you turned off setting for
python.terminal.shellIntegration.enabled so that it is false? (make sure you disable both user and workspace).

Make sure to reload as these changes wont be in effect until you reload after change this setting.
