Originally created by @thibaultdouzon on GitHub (Sep 26, 2019).

Environment

Windows build number: 10.0.18362.356,
Terminal: 0.5.2681.0

Python: tried with 3.6 and 3.8 (alpha)
I'm using conda to manage packages (ipython in this case)

This only happens in Terminal tabs, not in basic Powershell / Cmd windows.

Steps to reproduce

  • Open a tab (tried with powershell and cmd).

  • Run ipython

  • Start entering at least one character and then hit spacebar. No more char can be added to the line and ipython doesn't respond anymore.

  • Hit Ctrl + C to clear the line

Expected behavior

We should be able to write spaces in the ipython prompt

Actual behavior

Space characters are not printed out and make the prompt freeze.

Tried again today with version 0.6.2951.0, the bug is not reproducible anymore. Closing this.

I am encountering this exact bug on version 0.10.781.0. Also, maybe unrelated, I have the same bug using the integrated VsCode terminal.

Sorry for the late reply, for some reason it decided to start working again
without me doing anything in particular. I’m afraid I can’t help
