Go package for printing structs as tables in the terminal.

pterm uses reflection to get struct field names and tags to define formatting behaviour.

package main

import (
	"fmt"
	"github.com/Daniel-Zimmer/pterm"
	"math/rand"
	"time"
)

type Example struct {
	ID   string `json:"id" pterm:"2, right"`
	Name string `json:"name" pterm:"2, elastic"`
	Size string `json:"size" pterm:"left"`
}

func main() {
	sizes := []string{"BIG", "MEDIUM", "SMALL", "TINY"}
	names := []string{"Albert", "John", "Richard", "Mary", "Cleo", "Bernard", "Zimmer"}

	examples := make([]Example, 0)

	rand.Seed(time.Now().Unix())
	for i := 0; i < 15; i++ {
		examples = append(examples, Example{
			ID:   fmt.Sprintf("%x", rand.Int()),
			Name: names[rand.Intn(len(names))],
			Size: sizes[rand.Intn(len(sizes))],
		},
		)
	}

	pterm.PrintTable(examples)

}

Aligns to the left.

Aligns to the right.

How much padding to leave before the next column.

Example: "2"

Ignores the field.

Trims the strings in this column that would not fit in the terminal. Only one field can be elastic.

(99% sure this does not work on Windows)

Example: if one of the entries in the table is: "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." and the terminal is not wide enough to fit the entire string, the displayed value will be something like: "Lorem ipsum dolor sit...".

Name to use as column header instead of the name of the struct field. If you want to use any of the above keywords as struct names just add a "$" in front of the name.

Example: "$left"

If you want the column header to start with a "$" just use "$$" instead.
