FIGlet for Go

A port of figlet to golang and fork of getwe/figlet4go.

Installation

go get -u github.com/probandula/figlet4go/...

Usage

Command-line

You can use the figlet4go command in the command-line like this:

figlet4go Hello

For a usage instruction read the commands usage with figlet4go -h

Basic

You have to create a renderer (ascii) and let it render the desired string through the Render method. After that you can simply print the returned string.

ascii := figlet4go.NewAsciiRender()

renderStr, _ := ascii.Render("Hello World")
fmt.Print(renderStr)

Colored

The colors given in the []color.Attribute slice are repeating if the string is longer than the slice. You have to call the RenderOpts instead of the Render method to give the Renderer the Options.

ascii := figlet4go.NewAsciiRender()

// Adding the colors to RenderOptions
options := figlet4go.NewRenderOptions()
options.FontColor = []color.Attribute{
	color.FgGreen,
	color.FgYellow,
	color.FgCyan,
}

renderStr, _ := ascii.RenderOpts("Hello Colors", options)

fmt.Print(renderStr)

Other font

If you want to use another font, you have to specify the name of the font as in this example.
Is the font you want to use not included you have to load the font manually with the LoadFont method. This method will walk the path recursively and load all .flf files

ascii := figlet4go.NewAsciiRender()

options := figlet4go.NewRenderOptions()
options.FontName = "larry3d"

// If 'larry3d' wouldn't be included you would have to load your .flf files like that:
ascii.LoadFont("/path/to/fonts/")

renderStr, _ := ascii.RenderOpts("Hello Colors", options)

fmt.Print(renderStr)

Fonts

Builtin

The builtin fonts are built into the bindata.go file with the tool go-bindata.
The bash script for building the default font is stored in tools/ (go-bindata must be installed).

The default font is standard. These are the builtin fonts

Font name	Source
standard	http://www.figlet.org/fontdb_example.cgi?font=standard.flf
larry3d	http://www.figlet.org/fontdb_example.cgi?font=larry3d.flf

Other fonts

Other fonts can mainly be found on figlet. You have to load them as in this example.
