Examples of jline.ConsoleReader

jline.ConsoleReader
A reader for console applications. It supports custom tab-completion, saveable command history, and command line editing. On some platforms, platform-specific commands will need to be issued before the reader will function properly. See {@link Terminal#initializeTerminal} for conveniencemethods for issuing platform-specific setup commands. @author Marc Prud'hommeaux
