Class ConsoleLineExpander

java.lang.Object
org.jline.console.impl.ConsoleLineExpander
All Implemented Interfaces:
org.jline.shell.LineExpander
public class ConsoleLineExpander extends Object implements org.jline.shell.LineExpander
A LineExpander backed by a ConsoleEngine's parameter expansion.

This expander supports full ${expression} syntax with Groovy evaluation (or whatever script engine the ConsoleEngine is configured with), in addition to simple $variable expansion.

It delegates to ConsoleEngine.expandCommandLine(String) for the actual expansion logic, which supports script engine evaluation.

Example: 

 ConsoleEngine engine = ...;
 LineExpander expander = new ConsoleLineExpander(engine);
 Shell.builder()
     .lineExpander(expander)
     .build();
