Problem Description

When using TAB in the IPython console, auto completion repeats the previously entered characters. E.g. in case a variable should be assigned the result of a function call then autocomplete repeats the variable and the equals-sign before inserting the result of the autocomplete.

What steps reproduce the problem?

1. import any module, e.g. pandas as pd
2. enter "test = pd.con"
3. press TAB for completion (pd.concat)
4. completion will return "test = pd.concat" resulting in the line "test = test = pd.concat"

What is the expected output? What do you see instead?

The completed line should read "test = pd.concat", not "test = test = pd.concat"

Hey @physici, thanks for reporting. Did you change any option in

Preferences > IPython console > Advanced settings

from its default values?

Also, what's your IPython version? You didn't attach it to your report above.

[physici]

I've updated the bug report: IPython version 8.8.0.

I've also tried it with a different setup. The problem doesn't show up with the following configuration:
Python 3.10.6
Spyder 5.4.0
IPython 7.3.4

Advanced Settings for the IPython-Console:
Jedi -> off
Greedy -> off
Autocall -> off
Symbolic math -> off
Prompts: empty
Window adjustments -> On

Thanks for the additional details @physici. I can confirm this bug with IPython 8.8.0, but not with 8.7.0. So please downgrade to that version for now because it's going to take us some time to fix it.

[ccordoba12]

Note: This probably needs to be solved in Qtconsole.

[physici]

I've downgraded to IPython 8.7.0 as suggested and it solves the issue for me as well.

Unfortunately, the Spyder 5.4.2 macOS version on GitHub has IPython 8.8.0 bundled with it, so exhibits this bug.

I am still experiencing this bug with IPython 8.10.0 as well

Hi @krassowski, sorry for the ping but I saw that you are involved in many completion PRs on IPython lately. So, I'd like to ask you: is this something we need to address in Qtconsole? Or is it going to be fixed in a future release in IPython?

[krassowski]

Happy you pinged me. The fix was already merged: ipython/ipython#13943

Edit: it was not released yet, contrary to what I stated previously, it appears that it was merged after the latest release.

Ok, great! Thanks for the good news 👍🏽
