telnet to 2.8 REPL

I'd love to have this too, but nobody is likely to write it but me and
I'm hard pressed to call it the highest priority. Find me an employee
who will work for nothing but the joy of acquiring knowledge and maybe
we'll have something by 2.8.

I'm working on a swing-based front-end to deal with exactly this problem.
But I'm also over committed, so can't promise anything deadline-wise

Kevin,
Will this front-end be able to operate over, say, a forwarded TCP connection over ssh?

I'm really working on the GUI part right now, but the forwarding could theoretically be over anything

Sorry, master, I can't offer that, but thanks to Volkshochschule [1],
I'm now able to say hello in one more language.

So, let me introduce myself

In my euphoria, I went out to tell everyone and teach them the little
vocabulary I acquired. Fortunately, while I strived around in this
mood, I met Mrs. J. Line in persona. She wasn't too reluctant to learn
everything I knew. When she met her good acquaintance, Inta Preta, in

Just be careful that you don't trust your telnet client too much,some of them are less than honest about what they send
(yes windows, I'm looking at you)

I've got a whole bunch of this stuff I'm doing in scala+netty, though that's probably a library dependency we don't want in core Scala...  I've got no problem using it in an add-on though.

Right now, I'm working on a very rich mud client.  It's a commercial deal, but it's also mine, so I have no qualms in licensing it to myself :P
One day I'll break out the bits that are relevant for this mark em open source and turn it into a full on wizz-bangy remote REPL.  You'll appreciate that I can't release all the source, but significant chunks of it I planned to set free all along - such as scala wrappers for swing.text and the telnet protocol bits.

The code now lives in http://github.com/jrudolph/scala-stuff/tree/master/telnet/

I've updated the options which are sent, and now Ubuntu telnet and
putty on Windows work out of the box with default settings and with
the non-default port number. The Ubuntu telnet (netkit 0.17 from
1999?) does different things if you connect to port 23 vs another
port, but with the options negotiated it works now as expected.

Sounds very interesting...and inline with what i think no app should be
without (http://blog.homecloud.ca/2009/10/modern-applications.html)

If I got this right, we need to setup a (maybe secure) telnet sort of a rear
door to the interpreter, which would be available to any running scala app
and it will have access to and interact with the app's objects? With
niceties like tab completion etc...

It obviously needs to be a separate class/thing, which users may
instantiate/initialize in their main() or somewhere, just like the example,
with... yeah a port number and security info (key repo whatnot).

From here to supporting a simple web thing, with intelli-sense (content
assist) it's not a big step...cool! I'm in...

I don't mind thus switching to the dark side for a while...so, keeping in
mind that I am a fraud - at least in the sense that I haven't worked on
scala itself before - what shall I start with, master? What hooks are there?

I created a prototype:

The telnet will do tab completion when I figure out how to get the options
from the parser :)
