LineReader - mikesamuel/jline3 GitHub Wiki

The LineReader interface allows reading lines from a terminal, with full input/line editing.

Instances of LineReader can be obtained using the LineReaderBuilder class:

  Terminal terminal = ...;
  LineReader lineReader = LineReaderBuilder.builder()
                              .terminal(terminal)
                              .build();

LineReader building options

The builder can be customised to create more suitable line readers:

   LineReader lineReader = LineReaderBuilder.builder()
                              .terminal(terminal)
                              .completer(new MyCompleter())
                              .highlighter(new MyHighlighter())
                              .parser(new MyParser())
                              .build();
