Printing output to a command window when golang application is compiled with -ldflags -H=windowsgui

Question

I have an application that usually runs silent in the background, so I compile it with

To check

Answer 1

If you build a windowless app you can get output with PowerShell command Out-String

.\\main.exe | out-string

your build command may look like:

cls; go build -i -ldflags -H=windowsgui main.go; .\\main.exe | out-string;

or

cls; go run -ldflags -H=windowsgui main.go | out-string

No tricky syscalls nor kernel DLLs needed!
