python-mode is missing the class browser

[Michele Simionato]

I have noticed that the python-mode for Emacs that comes with the
latest Ubuntu is missing the class browser. Moreover if works
differently from the python-mode I was used to (for instance CTRL-c-c
works as CTRL-c-! whereas CTRL-c-! is missing, etc). How can I go back
to the old python-mode
or at least how do I get back the class browser?

I'm not really up2date wrt/ my ubuntu station here, but I remember
having seen this somewhat different (emacs-provided IIRC) python-mode
which I didn't like. I don't quite remember what I did, but I can at
least tell you what I have actually have:

- in /usr/share/emacs/site-lisp/python-mode/python-mode.el : the 'true'
python-mode which header goes like this:

FWIW and talking about class-browser, there's the IMHO very excellent
emacs-code-browser too.

There are two different and independently developedpython-modes. The
politically correct one that comes with emacs (IIRC python.el) that had pretty
limited functionality last time I looked, and the original but not FSF blessed
python-mode.el (http://sourceforge.net/projects/python-mode/), which should
come with install instructions. If you use ipython you might additionally
want to install ipython.el, which comes with the ipython tar ball.

I've got the same, and a IM-Python-menu that contains the class-browser.

Yes, it sure is cool.

And I have no idea how I ever worked without flymake & pylint :)

Emacs just rocks...

I have solved by using ipython.el which was already installed. For the
sake of
future googlers using Ubuntu 8.04, emacs and ipython, it is enough if
you just add

(setq ipython-command "/usr/bin/ipython")
(require 'ipython)

to your .emacs. It is nice since I get the occasion to try ipython.el
which I am
sure I will like ;)

So, I'm looking at the .el, but I'm not sure. What else does
ipython.el give you than just the ipython shell?

What else could you possibly want? :)

Seriously, ipython.el is a simple kludge whose only function is to make
python-mode work with ipython (rather than python[*]). Despite this certain
primitiveness (c.f. slime), Emacs+ipython makes quite a powerful development
environment, significantly more so than ipython alone or emacs + python. Most
importantly thre is:

1. debug. Try it: write some code that will throw an unhandled exception, and
just type ``debug``. Type ``u`` and ``d`` to go up and down the stack
frame, and see the right file and line pop up in emacs. I really find that
combined with the ability to do arbitrary things with the things I find on
the stack incredibly useful for development.

2. ? and ?? as well as ed. To get help on foo you just write ``foo?``. To get
its source code as well type ``foo??``. Finally to edit the code that
correspond's to foo's class or function definition (also works on class
instances)) type ``ed foo`` (IIIRCk the default behavior is autoexecution,
so you might want to re-alias).

3. Autocompletion with tab.

4. run (including -d and -p options). Try ``run?``

5. Matplotlib and gui stuff works interactively. (-pylab cmdline option)

6. Convenient Shell interaction (ls, !, int) and interpolation from and too
python

7. Pretty printing.

But there's plenty more stuff. The most useful in terms of added functionality
via emacs is 1, but isearch and emacs editing power make the ipython shell
output also noticably more useful (and thus things like ?, ?? and pretty
printing).

cheers,

[*] Inter alia the prompt parsing stuff needs to be different and the ansi
color formatting needs to be dealt with.

Unfortunately, ipython.el seems to be incompatible with use on your own scripts if they process command line options (e.g., optparse).
