consolesize-go's Issues

Headless mode?

Is there any way to get this to return the correct width in a headless terminal? I'm attempting to use this library inside a binary inside a Dockerfile and it returns 0,0 there.

Returns 0,0 for tests

It works completely fine when executed with go run main.go, even if the consolesize-go is imported down in other imported libraries from main.go. Even the binaries work fine.

However, it doesn't seem to do that for go tests. I wrote a simple test in a library_test.go file to show this:

package main

import (
	"fmt"
	"testing"

	"github.com/nathan-fiscaletti/consolesize-go"
)

func TestLibrary(t *testing.T) {
	cols, rows := consolesize.GetConsoleSize()
	fmt.Printf("Rows: %v\n", rows)
	fmt.Printf("Cols: %v\n\n", cols)

	t.FailNow()
}

When I execute go test library_test.go, I get the following output:

I've separated a chunk of my cli tool to be used as a library, but I can't write any tests for it due to this issue. Any idea how I could resolve this?
