Golang : Add ASCII art to command line application launching process
Problem : You worked hard on creating your application and you want add some ASCII art to prettify the launching process or simply want to make your program --help description pretty with a banner, version number, your name and etc.
For example :
Solution : Use github.com/common-nighthawk/go-figure package to add ASCII art in your application.
In case, you don't want your program to depend on external font .flf files, embed the font directly in your program as a constant and use strings.NewReader() function to load the font directly.
Here you go!
package main
import (
"strings"
figure "github.com/common-nighthawk/go-figure"
)
func main() {
// basic stuff
banner := figure.NewFigure("Hello World", "", true)
banner.Print()
// with isometric2 font
// see the list of available fonts at
// https://github.com/common-nighthawk/go-figure/tree/master/fonts
banner2 := figure.NewFigure("Hello World2", "isometric2", true)
banner2.Print()
// in case you need to use your own font.
// OR you just want to deploy your executable file WITHOUT including
// the Figlet .flf font file.
figure.NewFigureWithFont("My Awesome Program!!!", strings.NewReader(SubZeroFont), true).Print()
}
// Source :
// https://raw.githubusercontent.com/xero/figlet-fonts/master/Sub-Zero.flf
var SubZeroFont = `
flf2a$ 6 5 17 -1 16
"Sub-Zero" font by Sub-Zero
==============================
-> Conversion to FigLet font by MEPH. (Part of ASCII Editor Service Pack I)
(http://studenten.freepage.de/meph/ascii/ascii/editor/_index.htm)
-> Defined: ASCII code alphabet
-> Uppercase characters only.

"Here's a font I've been working on lately. Can someone make the V, Q, and X
look better? Also, the B, P, and R could use an improvement too.
Oh, here it is."
