Golang : How to check if your program is running in a terminal
Problem:
Your command line application accepts inputs from a terminal only or you just want to test if the application is really running under a terminal. How to check if the application is really running under a terminal?
Solution:
Use the github.com/mattn/go-isatty package to determine if your application running under Terminal, Windows Cygwin/MSYS2.
For example, running this code ( from github.com/mattn/go-isatty ) under a terminal
package main
import (
"fmt"
"github.com/mattn/go-isatty"
"os"
)
func main() {
if isatty.IsTerminal(os.Stdout.Fd()) {
fmt.Println("Is Terminal")
} else if isatty.IsCygwinTerminal(os.Stdout.Fd()) {
fmt.Println("Is Cygwin/MSYS2 Terminal")
} else {
fmt.Println("Is Not Terminal")
}
}
will give:
Is Terminal
and if you execute the code under Gogland IDE, you will get Is Not Terminal
:
GOROOT=/usr/local/go
GOPATH=/Users/admin/go
/usr/local/go/bin/go build -i -o /private/var/folders/mt/p1knsj5x45901p6t3q0kxpq40000gn/T/Buildmaingoandrungo
/Users/admin/GoglandProjects/ReallyTerminal/main.go
/private/var/folders/mt/p1knsj5x45901p6t3q0kxpq40000gn/T/Buildmaingoandrungo
Is Not Terminal
Process finished with exit code 0
Hope this helps!
