Old Question Revisited: Java Curses Support

Hello James,
</STRONG></P>
<P><STRONG>
I don't mean to be too critical -- afterall, I realize that you must be
faced with many emails and deadlines when writing your articles for The
Answer Guy.
</STRONG></P>
<P><STRONG>
Still, I thought I should point out that you didn't help Spencer T.
Kittelson when he asked for a "Java equiv. of a C curses library".
You pointed him to Java terminal emulation applications like JXTerm or
SCO's Tarantella. If he was asking for a java telnet program, I'm sure
JXTerm would have been a good answer. Unfortunately, he wasn't (I think
the use of the words "curses library" gives it away here).
</STRONG></P>

That's an old one. I remember that I searched around
quite a bit on the net for the suggestions that I did
give him. SCO's Tarantella is closed source, of course.
I remember that part of what I was looking for was
an open source Java terminal emulator (on the silly idea
that this might be built over a curses-like library).
</BLOCKQUOTE>
<BLOCKQUOTE>
Come to think of it, how hard would it be to port
ncurses to Java? Of course you have to get Java to
provide a terminal interface (which is why I started with
the suggestions that related to that).
</BLOCKQUOTE>

In actual fact, he was asking for a framework/library for developing
terminal applications in the Java Programming Language. In other words,
he wanted to be able to write in Java something like PINE or "top" or
irc-ii, but without Swing or AWT and relying solely on a user having
only terminal capabilities.
</STRONG></P>

Oh! That is a different interpretation of the question.
</BLOCKQUOTE>
<BLOCKQUOTE>
Using Java to write curses mode programs? Well, that would
be nice --- but I don't think it will gain any attention.
I'd think that C and Python and PERL have that space pretty
solidly sewn up.
</BLOCKQUOTE>
<BLOCKQUOTE>
Python seems to have pretty decent curses support, and
it has many of the same OO features and dynamic protections
that Java promises. Meanwhile text-mode/curses support
seems so far away from Java's core focus that it seems like
an unlikely avenue for future development.
