'stty' is not recognized

[tuomohopia]

I keep getting this on my vscode:

'stty' is not recognized as an internal or external command,
operable program or batch file.

hie itself is not working at all now, but I don't know if it's due to this error or not.

I'm running:

• Win10
• hie-8.6.5
• lts-14.11

[tuomohopia]

Looks like I didn't have the correct msys2 folder in my PATH. Now that I do, I'm getting this kind of error:

stty: 'standard input': Inappropriate ioctl for device

I've got that message too in my windows machines continuously, not only with hie but with other haskell programs.
It doesn't block or affect their execution.
I think it is caused by some upstream widely used lib.

@jneira yeah I think this is a problem with stack.

I was able to resolve this somehow with a tip from:
commercialhaskell/stack#4968

Basically, I made a stty.bat with the content:

@IF "%1"=="size" exit 255

Wow, thanks for the link and the workaround.
I hope they will merge the pr with the definitive solution

I did as instructed and created a stty.bat file with the @IF "%1"=="size" exit 255 line and put it in PATH. Unfortunately this fix does not work for me when I open the Purescript compiler project. I still get the 'stty' is not recognized as an internal or external command, operable program or batch file. error.

mmm, do you get those messages if you do a stack build (hie triggers internally calls to stack)?

[mrakgr]

I just did a stack clean, then stack build. I did a search for stty on the command line output, but nothing comes up so this is a sure no.

[jneira]

Mmm, i've just the same output, having the script stty.cmd in ghcide:

[DEBUG] Finishing shakeRun (took 0.10s, exception: AsyncCancelled)

The output is just after running the cradle, like seems to be in hie so i wonder if hie-bios could be involved here. The %PATH% has to be altered in some way to get this output, having stty.cmd in %PATH%.
