Problem with terminal's command promt after execution of scala scripts

[BarkingBad]

Compiler version

Scala compiler version 3.0.0-RC2-bin-SNAPSHOT-git-c037293 -- Copyright 2002-2021, LAMP/EPFL

Execution of scripts like /bin/scalac or /bin/scaladoc breaks the terminal, command prompt is not in new line position and typing is invisible

Operating system:
Description: Ubuntu 20.04.1 LTS
Release: 20.04

I am using default bash terminal.

@philwalk could you take a look, as it seems problem exists since your recent changes. Thanks in advance :D

I encountered the same issue (aka "typing is invisible") with the MinGW shell prompt (on MS Windows).

[philwalk]

I was able to reproduce the problem on Ubuntu release 18.04.1 ... looking into it.

[philwalk]

I have a probable fix, but I need to verify that it works with all environments.

It turns out that manual REPL tests that have to be performed for 4 terminals over 5 windows shell environments, plus Linux, Linux-WSL and OSX.

That's more than 20 terminal/shell combinations.

Terminals:

• cmd
• mintty
• conemu
• windows terminal

Windows Shell environments:

• MINGW32_NT-10.0-19042 d5 3.1.7-340.x86_64 2020-11-08 12:32 UTC x86_64 Msys
• MINGW64_NT-10.0-19042 d5 3.1.7-340.x86_64 2020-11-08 12:32 UTC x86_64 Msys
• MSYS_NT-10.0-19042 d5 3.1.7-340.x86_64 2020-11-08 12:32 UTC x86_64 Msys
• CYGWIN_NT-10.0 d5 3.1.7(0.340/5/3) 2020-08-22 17:48 x86_64 Cygwin
• Linux d5 5.4.72-microsoft-standard-WSL2 allow lazy loading of parts of types #1 SMP Wed Oct 28 23:40:43 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

In addition, I'm currently able to do manual REPL tests on Ubuntu Linux:
Linux quadd 5.4.0-62-generic #70~18.04.1-Ubuntu SMP Tue Jan 12 17:18:00 UTC 2021 x86_64 x86_64

• x86_64 GNU/Linux

We should also test OSX/Darwin as well (not currently able to do so myself).
Maybe also need to test X-windows ssh sessions ...

I Will push a working fix soon, hopefully.
