Functions

func Examples

func Examples(wr io.Writer) error

Examples writes the list command examples.

func Printable

func Printable(name string) bool

Printable reports whether the named encoding can be shown as a 256 character table. UTF-16 and UTF-32 are not printable.

func Table

func Table(w io.Writer, names ...string) error

Table writes one or more named encodings as a formatted table.

Example

package main

import (
	"fmt"
	"log"
	"os"
	"strings"

	"github.com/bengarrett/retrotxtgo/cmd/list"
	"github.com/gookit/color"
)

func main() {
	color.Enable = false
	names := []string{"cp437"}
	s := strings.Builder{}
	if err := list.Table(&s, names...); err != nil {
		log.Fatal(err)
	}
	fmt.Fprintf(os.Stdout, "%d characters in the table", len(s.String()))
}

Output:

1693 characters in the table

func Tables

	"github.com/bengarrett/retrotxtgo/cmd/list"
	"github.com/gookit/color"
)

func main() {
	color.Enable = false
	s := strings.Builder{}
	if err := list.Tables(&s); err != nil {
		log.Print(err)
	}
	const val = 70000
	l := s.Len()
	fmt.Fprintf(os.Stdout, "characters > 70000: %v", l > val)
}

Output:

characters > 70000: true
