Issue2338

My patched version of IPython 0.10.2 crashed on startup with jython 2.7rc3.

The reason was simply mismatch of attribute name.

<     _console.startup_hook = function
---
>     _console.startupHook = function

With this change, the old Ipython did start. No tab completion, sadly.

Let's see if we can get the current version of IPython to work in 2.7.1. Please note that Jython's default console now supports tab completion.

there's a setStartupHook method, one probably should
use that one.

As a side note, I'm trying this https://github.com/Britefury/ipython/tree/basic-jython-fixes branch, and with
the change in readline.py I have IPython 3.0 running.  Tab completion does work, but is a bit wonky.

This is the diff against current trunk:

 def set_pre_input_hook(function=None):
     warn("set_pre_input_hook %s" % (function,), NotImplementedWarning, stacklevel=2)

This is an easy fix, but hard to test with something like pexpect. In part, this is because JLine2 does not have completely compatible support compared to readline for this functionality, especially under a pty. I also suspect that this may vary from platform to platform (OS X vs Linux vs Windows), but something we need to look into more.

I made this very minor change, since this is an obvious fix, even if we don't have a regrtest to verify (yet).

Still waiting on robust pexpect testing, using CPython to drive that test; and likely some fixes against JLine2. But let's not have the perfect stand in the way of some progress here.

Fixed as of https://hg.python.org/jython/rev/93c09145137e
