How to have panic messages show in a PowerShell console

[Thom BENTLEY]

Hi All, 

OS: Windows 10

GoLang: go1.6.3 windows/386

I am trying to have a go executable run and show the panics it causes in the PowerShell console.  

I think I can use GODEBUG, but all the examples I've seen so far are for Linux.
I've set that variable to paniclog=1, but nothing changed.

If I run go env, I don't see GODEBUG listed.

Thanks in advance.

You should upgrade your Go installation to the latest version and retry. Go 1.6.3, if that is not a typo is very old.

Thanks Jim.
At the moment, I’m using the 1.6.3 version as specified in the internal documentation the project I’m learning.
I would definitely like to upgrade go to a much later version.  Just don’t want to do it before I know it works on the specified version.

The Go backward compatibility guarantee makes it almost a certainty the project you're working on will work fine if you upgrade to the current Go release. There is always a very tiny chance the project depends on a bug that has been fixed in a newer release but that is so unlikely that I wouldn't worry about it. Also, if you upgrade to the current Go release and have problems (which is unlikely) you can always go back to the old version. The bottom line is that you are unlikely to get any meaningful assistance with an ancient Go version.

FWIW,  in a very simple test on Windows 10 in a powershell console, running a go executable built with go1.19 prints the panic just like in a regular cmd console.

There have been a lot of changes related to Windows consoles since the
1.6 release.

I just discovered that the executable is created using -ldflags -H=windowsgui. 

Because of that, I need to pipe to out-text in a PowerShell to see Println output but that doesn’t show the panics.

If I remove the flags, then I can see all the output.  I don’t know if they are absolutely needed so I may not be able to remove them.
I tried a few “windows” calls to setup a console for when built with the flags.  Nothing worked so far.
And, I know I may need to move to a later version of Go to get better help.  That will need some discussion with others on my team.

 

Thanks!
