Originally created by @bogdanm on GitHub (Jan 29, 2021).

Environment

Windows build number:

Platform ServicePack Version      VersionString
-------- ----------- -------      -------------
 Win32NT 10.0.19042.0 Microsoft Windows NT 10.0.19042.0

Windows Terminal version: Windows Terminal Preview version 1.6.10272.0 (but note that this also happened in previous versions)

Powershell version:

Major  Minor  Build  Revision
-----  -----  -----  --------
5      1      19041  610

Steps to reproduce

  • Open a Powershell window in Windows Terminal.
  • Install Lua 5.1, for example using "scoop" (scoop install lua-for-windows) (my version is 5.1.5-52). NOTE: this behavior was noticed in other programs too, not just the Lua REPL (for example, the Python 3.8.7 REPL behaves in the exact same way).
  • Start the Lua REPL ("lua")
  • Press CTRL+C after the REPL starts.

Expected behavior

The Lua REPL exists and the Powershell prompt is displayed again.

Actual behavior

The Powershell window closes completely. If the Powershell window was the single window inside Windows Terminal, then Windows Terminal exits too.

Other information

This doesn't happen if I run Powershell separately (Win+R then "powershell"). In this case, the Lua REPL exists as expected.

This doesn't happen if I run the lua REPL in a command prompt window (not Powershell) inside Windows Terminal. Again, in this case, the Lua REPL exists as expected.

This sounds a lot like #4899. That one was using pwsh 7 from scoop, but I wonder if installing Lua from scoop would do the same thing.

Thanks for your reply. It might be a different issue here though:

  • I did not install Powershell via scoop
  • The same thing happens when I run the Python 3.8.7 REPL (which is not installed via scoop either).

I just did another experiment:

The exact same thing happened. It looks like a lot of programs that expose a REPL-like interface are affected.

@bogdanm commented on GitHub (Jan 29, 2021): I just did another experiment: - I downloaded the SQLite CLI from https://sqlite.org/download.html (https://sqlite.org/2021/sqlite-tools-win32-x86-3340100.zip) and unpacked it somewhere in my PATH. - I ran `sqlite3` from Powershell inside Windows Terminal. The exact same thing happened. It looks like a lot of programs that expose a REPL-like interface are affected.

What's the version of your PowerShell & PSReadline? I can't reproduce this issue on my machine.

Unfortunately I didn't write down the previous version of the PSReadline package on my machine, however I updated it using the instructions from https://github.com/PowerShell/PSReadLine/ and now everything works as expected. Thank you, I didn't even think about PSReadline as a possible cause for this issue.
