Class AWTConsole

class
AWTConsole
extends TextArea
implements ConsoleInterface, Runnable, KeyListener
An old AWT based console for BeanShell.
I looked everwhere for one, and couldn't find anything that worked.
I've tried to keep this as small as possible, no frills.
(Well, one frill - a simple history with the up/down arrows)
My hope is that this can be moved to a lightweight (portable) component
with JFC soon... but Swing is still very slow and buggy.
Done: see JConsole.java
The big Hack:
The heinous, disguisting hack in here is to keep the caret (cursor)
at the bottom of the text (without the user having to constantly click
at the bottom). It wouldn't be so bad if the damned setCaretPostition()
worked as expected. But the AWT TextArea for some insane reason treats
NLs as characters... oh, and it refuses to let you set a caret position
greater than the text length - for which it counts NLs as *one* character.
The glorious hack to fix this is to go the TextComponent peer. I really
hate this.
Out of date:
This class is out of date. It does not use the special blocking piped
input stream that the jconsole uses.
Deprecation:
This file uses two deprecate APIs. We want to be a PrintStream so
that we can redirect stdout to our console... I don't see a way around
this. Also we have to use getPeer() for the big hack above.
