Library not compatible with text/tabwriter

[iblancasa]

It seems the library doesn't work well with text/tabwriter.

I created a tabwriter like this:

w := tabwriter.NewWriter(os.Stdout, 0, 0, 2, ' ', tabwriter.Debug)

Created the strings with colors like this:

color.RedString("Unmaintained")

And printed with fmt.Fprintf.

I encountered a similar strangeness:

With Colored Header

type info struct { ... }

func createTable(rows ...info) {
	var buf bytes.Buffer
	w := tabwriter.NewWriter(&buf, 0, 0, 1, ' ', tabwriter.Debug)

	color.New(color.FgWhite).Fprintln(w, "Name\tAvailability\tSoftware Build\tNotes")
	for _, row := range rows {
		color.New(color.FgCyan).Fprintf(
			w,
			strings.Join([]string{
				row.Name,
				string(row.Availability),
				row.SoftwareVersion,
				row.Comment,
			}, "\t"),
		)
	}

	w.Flush()
	fmt.Println(buf.String())
}

Without Colored Header

type info struct { ... }

func createTable(rows ...info) {
	var buf bytes.Buffer
	w := tabwriter.NewWriter(&buf, 0, 0, 1, ' ', tabwriter.Debug)

	fmt.Fprintln(w, "Name\tAvailability\tSoftware Build\tNotes")
	for _, row := range rows {
		color.New(color.FgCyan).Fprintf(
			w,
			strings.Join([]string{
				row.Name,
				string(row.Availability),
				row.SoftwareVersion,
				row.Comment,
			}, "\t"),
		)
	}

	w.Flush()
	fmt.Println(buf.String())
}

Alas, this may be just a constraint of tabwriter: https://github.com/juju/ansiterm/blob/8b71cc96ebdcf1786021219160dacfda2b51cdbe/tabwriter/tabwriter.go#L400-L404
