Posted by GoDoc

Public (Editable by Users)

Package tabwriter implements a write filter (tabwriter.Writer) that translates tabbed columns in input into properly aligned text.

Language Go

Dependencies

import "fmt"

import "os"

import "text/tabwriter"

tabwriter.NewWriter()

Edit

main.go

package main

import (
	"fmt"
	"os"
	"text/tabwriter"
)

func main() {
	// Observe that the third line has no trailing tab,
	// so its final cell is not part of an aligned column.
	const padding = 3
	w := tabwriter.NewWriter(os.Stdout, 0, 0, padding, '-', tabwriter.AlignRight|tabwriter.Debug)
	fmt.Fprintln(w, "a\tb\taligned\t")
	fmt.Fprintln(w, "aa\tbb\taligned\t")
	fmt.Fprintln(w, "aaa\tbbb\tunaligned") // no trailing tab
	fmt.Fprintln(w, "aaaa\tbbbb\taligned\t")
	w.Flush()
}
