term.fs (lib)

The term.fs library helps you emulate a terminal on the screen.

Usage

Use init-term to initialise this library. In order to be able to write anything to the screen, you need to install a font as a tileset first. You can use ibm-font.fs for this.

require ibm-font.fs
require term.fs

: main
  install-font
  init-term ;
