Get terminal width in Windows using golang

Question

Is it possible to get the terminal width in Go?

I tried using http://github.com/nsf/termbox-go with the code:

package main

import (
    "fmt"

    "github.com/nsf/termbox-go"
)

func main() {
    fmt.Println(termbox.Size())
}

But it prints 0 0.

I also tried http://github.com/buger/goterm but when I try to go get it, I get an error:

$ go get github.com/buger/goterm
# github.com/buger/goterm
..\..\buger\goterm\terminal.go:78: undefined: syscall.SYS_IOCTL
..\..\buger\goterm\terminal.go:82: not enough arguments in call to syscall.Syscall

Any other ideas on how to get the terminal width?

You need to call termbox.Init() before you call termbox.Size(), and then termbox.Close() when you're done.

package main

import (
    "fmt"

    "github.com/nsf/termbox-go"
)

func main() {
    if err := termbox.Init(); err != nil {
        panic(err)
    }
    w, h := termbox.Size()
    termbox.Close()
    fmt.Println(w, h)
}
