launch/run IPython in emacs buffer

launch/run IPython in emacs buffer

[Tom Roche]

I can run IPython in an emacs buffer, but would appreciate help with
either of 2 problems:

0 opening an IPython buffer "from anywhere." I can open IPython in an
  emacs buffer with the sequence

* open buffer on a python file, e.g. C-x C-f /tmp/py.py
* C-c !

  This seems to work appropriately, e.g. M-p scrolls IPython history.
  However

* I'd like also to be able to open an IPython buffer from anywhere (in
  emacs), since I often use IPython as a calculator and scratchpad.

* I don't know of an existing command or config that does this.

* I don't know enough elisp to do this.

  Hence I'd appreciate a pointer to an existing command or config, or
  some elisp (or both) that will open an IPython buffer from anywhere in
  emacs.

1 fix M-p in IPython in shell-mode. When I run IPython in emacs shell
  mode (i.e. running `ipython` from a prompt after running `M-x shell`),
  IPython runs (with correct prompt, thanks Andrew Wilson). But when I
  attempt to scroll IPython history (with M-p at the IPython prompt), I
  instead get bash history. Is there a way to make shell-mode pass the
  M-p event to IPython?

FWIW, I'm running

Ubuntu 10.04.1 LTS, GNOME, 64-bit
GNU Emacs 23.1.50.1 from ubuntu package=emacs-snapshot
IPython 0.10 from ubuntu package
python-mode 5.1.0 from https://launchpad.net/python-mode/
Python 2.6.5 from ubuntu package

TIA, Tom Roche <Tom_Roche@pobox.com>

M-x py-shell 

will get you a new (I)Python shell.

This works for me in the sense that I get history from emacs (via comint) rather than IPython's history, which works pretty well.  It sounds to me as if comint (which is responsible for running IPython) is picking up your bash shell history. In fact if I have a running IPython shell and then start a new zsh with M-x shell, type a couple of shell commands to the shell and then use M-p to get the history,  I get the shell commands and followed by my most recent IPython commands and switching buffers to IPython and using M-p gives me the shell commands and then the IPython history.  It looks to me as if you might do something like what's on the emacswiki: http://www.emacswiki.org/emacs/UsingMultipleShells , but I'm afraid I haven't time right now to try it.

Best,
Richard Everson.

Hi,

Ipython sends code to python.

 From a common emacs buffer this was done by pymacs.
Didn't try it last times.

interesting point.

ipython has it's own user and devel list

maybe send your request here

http://mail.scipy.org/mailman/listinfo/ipython-user

also see

http://ipython.scipy.org/moin/

resp.

http://github.com/ipython/ipython/issues

Richard: exactly what I wanted.

Pythoneers: IMHO this would be good to add to the docs, e.g.

http://ipython.scipy.org/doc/stable/html/config/initial_config.html
- This should give you full support for executing code snippets via
- IPython, opening IPython as your Python shell via C-c !, etc.

+ This should give you full support for executing code snippets via

YMMV, Tom Roche <Tom_Roche@pobox.com>
