Interactive console in Pydev
Last week I started working on an interactive console and bundling it into pydev. Hopefully it'll be finished soon (probably within the next 1-2 weeks).
The main structure is already in place... code-completion, context info on hover, history (up/down arrow), colors for stdout/err/prompt/user input, auto-indent, python/jython support, it's all there already... (but I want to add an extra layer of polishment before releasing it).
Under the hood, it's almost like a whole new editor covering the console, while communicating through sockets with a python shell (but it feels a lot like a regular editor, in the sense that the same options that are used in the editor for indent, code completion, etc. are also available from the console -- with the exception that you can actually only edit the active line).
Also, this time I was able to get some code that had an initial draft of a console from dltk (which was pretty nice), but I had to do some (not so minor) changes to be able to add it to pydev, although the basic structure still has the same idea (the result can be seen at org.python.pydev/src_dltk_console).
Well, to sum it up... this is a long-awaited feature, and the plans are for surpassing all expectations on that :)

Sweet...
How will this compare to iPython? I've often wished I could get iPython directly into pydev and set it up so that when I run %edit it just opens a new file right there in pydev for me, saving it runs it in the iPython console. Would be great to setup an initial setup in the project definition so that when I go to work on my Django project, the shell is setup with the paths and such I need for that. Then if I go to another project, the shell would update as well.
deuce868's comment about iPython; Seconded!
You sir, are a gentleman and a scholar. I just installed and tested PyDev for a uni project, and was thinking 'hey, this is absolutely fantastic, but I wish I didn't have to have IDLE running as well for on-the-fly experimentation'

after that the console works but nothing was imported. A couple of newlines at the beginning of the initial import in the preferences seem to help, but the jython console doesn't work at all:

This seems like you have something blocking communication with the shell... do you have some firewall enabled?
Can someone tell me how to install this test version? I would love to try it out.
It has just been released: http://pydev.blogspot.com/2008/04/pydev-1315-released-new-interactive.html

"This seems like you have something blocking communication with the shell... do you have some firewall enabled?"
No, I have no firewall. I suspect some kind of race condition (it behaves like random and it has something to do with time), sometimes it works with only 2 empty lines at the beginning, sometimes not and today it worked one out of two times without an empty line at the beginning. After the prompt is there the console (CPython) works perfectly, but the Jython console won't work at all.
I have Kubuntu 7.10, Eclipse 3.3.2, PyDev 1.3.15, PyDev-Extensions deactivated because of another indeterministic problem, Hardware is an old ThinkPad-T40 (Pentium-M 1500MHz, 500MB RAM).
Can you please report that as a bug in sf?
cannot get interactive console during debug, e.g, to check functions and variables, etc. The usual stuff a debugger has.

I have the following error too:
>>> import sys; print '%s %s' % (sys.executable or sys.platform, sys.version)

I'm using a remote python debugger with my target. Is there any dependency on whether the target env is remote or local?
My host is ubunto 8.04 with eclipse 3.4 and pydev 1.3.18
Is there some diagnostic or tracing that I can turn on to help debug this?
That specific bug should be already fixed in the latest version in the cvs.
Cheers,

Is there any plans for IPython integration?
There are no plans for the iPython integration... Is there some specific feature of iPython that you're missing from the interactive console?
The Pydev console is great and in my opinion a must-have for development so many thanks for the good work put into this. I can't make it work in debug mode however - any plans to add this in?
There are currently no plans to add that support to the debugger. Note that pydev extensions has a simple console already (you can type statements to be evaluated, but it has no code-completion: http://fabioz.com/pydev/manual_adv_debug_console.html )
ok thanks, that seems to do the job. Will try it out.
