AnsiTerminal wraps a RichText widget and provides methods to print ANSI escape sequences.

The AnsiBuf class provides convenient methods for generating ANSI escape sequences.

Quick Start

1. Create a text file called Example.fan

   using gfx::Size
   using fwt::Window
   using afTerminal
   
   class Example {
       Void main() {
           term := AnsiTerminal()
           ansi := AnsiBuf()
               .fgIdx( 9).print("RED\n").reset
               .fgIdx(10).print("GREEN\n").reset
               .fgIdx(12).print("BLUE\n").reset
               .underline.print("Underline").reset
   
           Window {
               it.title = "ANSI Terminal"
               it.size = Size(320, 200)
               it.add(term.richText)
               it.onOpen.add |->| {
                   term.print(ansi)
               }
           }.open
       }
   }
   

2. Run Example.fan as a Fantom script from the command line:

   C:\> fan Example.fan
