How would I open a second python interpreter in emacs? I am using emacs 24.3 and Ubuntu 12.04 LTS. I have opened the SQL interpreter/program via a prefix argument of 2. I tried this with python and it did not work.
Any suggestions and ideas are welcome. The mode in my current python interpreter buffer says: Inferior Python: run Shell-Compile I have downloaded python-mode 6.10 from ELPA the emacs package manager.
Thanks for all the help!
M-x describe-function (RET) run-python:
run-python is an interactive compiled Lisp function in `python.el'.
(run-python &optional CMD NOSHOW NEW)
Run an inferior Python process, input and output via buffer Python. CMD is the Python command to run. NOSHOW non-nil means don't show the buffer automatically.
Interactively, a prefix arg means to prompt for the initial Python command line (default is `python-command').
A new process is started if one isn't running attached to
python-buffer', or if called from Lisp with non-nil arg NEW. Otherwise, if a process is already running inpython-buffer', switch to that buffer....
In the *scratch* buffer:
(run-python nil nil 't)
That will give you a new Inferior Python process.
You could code up a new interactive emacs command in your .emacs file, something like:
(defun my-run-python ()
(interactive)
(run-python nil nil 't))
C-x b *scratch*, and then say yes to create it. Alternatively, I think you can do M-x lisp-interaction-mode in any buffer to make it into an equivalent buffer. BTW, put your cursor at the end of your last right paren in your lisp expression and C-x C-e to evaluate the expression.nil in the mini-buffer.
(run-python nil 't 't) worked for modern emacsC-u M-x python
BTW your python-mode version is outdated. Recommend to fetch a new one doing
bzr branch lp:python-mode
or visit
el-get, https://github.com/dimitri/el-get distributes a reasonably updated version. Also you might replace old python-mode.el by hand.
M-x run-python?
