TablePrinter

tableprinter is an intelligent value-to-table formatter and writer. It uses a customized version of olekukonko/tablewriter to render a result table.

It checks every in data and transforms those data(structure values, slices, maps, single lists that may contain different type of values such as go standard values like int, string even a value that implements the fmt.Stringer interface) to a table formatted text and outputs it to an io.Writer. Like encoding/json#Encode but for tables.

Installation

The only requirement is the Go Programming Language, at least version 1.10.

$ go get -u github.com/lensesio/tableprinter

package main

import (
    "os"
    "sort"

    "github.com/kataras/tablewriter"
    "github.com/lensesio/tableprinter"
)

type person struct {
    Firstname string `header:"first name"`
    Lastname  string `header:"last name"`
}

func main() {
    printer := tableprinter.New(os.Stdout)
    persons := []person{
        {"Chris", "Doukas"},
        {"Georgios", "Callas"},
        {"Ioannis", "Christou"},
        {"Nikolaos", "Doukas"},
        {"Dimitrios", "Dellis"},
    }

    sort.Slice(persons, func(i, j int) bool {
        return persons[j].Firstname > persons[i].Firstname
    })

    // Optionally, customize the table, import of the underline 'tablewriter' package is required for that.
    printer.BorderTop, printer.BorderBottom, printer.BorderLeft, printer.BorderRight = true, true, true, true
    printer.CenterSeparator = "│"
    printer.ColumnSeparator = "│"
    printer.RowSeparator = "─"
    printer.HeaderBgColor = tablewriter.BgBlackColor
    printer.HeaderFgColor = tablewriter.FgGreenColor

    // Print the slice of structs as table, as shown above.
    printer.Print(persons)
}
