[SciPy-user] IPython completion

I was using Python2.3 on Solaris 8 when I reported yesterday. I have
found the same to be true on my Linux (RH-9.0) box as well. Here is the
information you requested below, but for the linux box instead:
Python 2.3 (#1, Sep 9 2003, 09:49:11)
Type "copyright", "credits" or "license" for more information.
IPython 0.5.0 -- An enhanced Interactive Python.
? -> Introduction to IPython's features.
@magic -> Information about IPython's 'magic' @ functions.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.
IPython profile: numeric
*** Your version of Gnuplot appears not to have mouse support.
*** Type `gphelp` for help on the Gnuplot integration features.
In : import readline
In : readline?
Base Class: <type 'module'>
String Form: <module 'readline' from
Importing this module enables command line editing using GNU readline.
In : dir(readline)
I also moved .ipython aside to allow for the creation of a new one, but
it didn't help. There is no ~/.inputrc file, so no local customizations
to the underlying readline library have been made. A quick comparison
of the readline.c source for Python2.2 and Python2.3 shows many
differences, so it's possible that some default behavior has changed. I
should reiterate that there is no problem with using <tab> to complete
names within the python namespace. It's just the completion of file/dir
names that does not work.
