hookIntoRuntime

public void hookIntoRuntime(Ruby runtime)

Hooks this TextAreaReadline instance into the runtime, redefining the Readline module so that it uses this object. This method does not redefine the standard input-output streams. If you need that, use hookIntoRuntimeWithStreams(Ruby).

Parameters:

runtime - The runtime.

hookIntoRuntimeWithStreams

public void hookIntoRuntimeWithStreams(Ruby runtime)

Hooks this TextAreaReadline instance into the runtime, redefining the Readline module so that it uses this object. This method also redefines the standard input-output streams accordingly.

Parameters:

runtime - The runtime.
