Elpy: Using ipython with Elpy

[wonbyte]

Hi,
I am trying to get ipython to be my default interpreter with ELPY.

Here is my current ELPY config:

(add-hook 'python-mode-hook 'elpy-mode)
(with-eval-after-load 'elpy
  (remove-hook 'elpy-modules 'elpy-module-flymake)
  (add-hook 'elpy-mode-hook 'elpy-rpc-python-command "python3")
  (add-hook 'elpy-mode-hook 'flycheck-mode)
  (add-hook 'elpy-mode-hook 'elpy-use-ipython)
  (add-hook 'elpy-mode-hook 'py-autopep8-enable-on-save))

After I start emacs, I use the pyvenv-activate command to load my virtualenv with all the required pip packages for ELPY.

I then have to run M-x run-python to get the elpy RPC process to start (Does it not automatically start up?)

When I run C-c C-C to send my code to the REPL it is using the standard Python 3 REPL and not the IPython one.

I am not sure what I am doing wrong to get IPython to be my default REPL.

Here is my ELPY Config

Elpy Configuration

Virtualenv........:  (/Users/gsieran/src/python/dive-into-python3/)
RPC Python........: 3.5.2 (/Users/gsieran/src/python/dive-into-python3/bin/python)
Interactive Python: ipython (/Users/gsieran/src/python/dive-into-python3/bin/ipython)
Emacs.............: 24.5.1
Elpy..............: 1.12.0
Jedi..............: Not found (0.9.0 available)
Rope..............: 0.10.3
Importmagic.......: 0.1.7
Autopep8..........: 1.2.4
Yapf..............: 0.11.0
Syntax checker....: flake8 (/Users/gsieran/src/python/dive-into-python3/bin/flake8)

Thank you for the help

(elpy-use-ipython "ipython3") would do

Thanks @yitang . I added that to my init.el like so:

(add-hook 'python-mode-hook 'elpy-mode)
(with-eval-after-load 'elpy
  (remove-hook 'elpy-modules 'elpy-module-flymake)
  (add-hook 'elpy-mode-hook 'flycheck-mode)
  (add-hook 'elpy-mode-hook 'elpy-use-ipython "ipython3")
  (add-hook 'elpy-mode-hook 'py-autopep8-enable-on-save))

Strangely, my ipython REPL that pops up looks like this:

Any ideas what is going on here?

[yitang]

are you using ipython3 5.0? if so, add this
(setq python-shell-interpreter "ipython3" python-shell-interpreter-args "--simple-prompt --pprint")

Thanks @yitang that fixed my prompt. Just curious why this is now needed to make the prompt display correctly?

[yitang]

ipython 5 use new terminal interface, see http://emacs.stackexchange.com/questions/24453/weird-shell-output-when-using-ipython-5

Best wishes,

Thanks @yitang , last question. Every time I start up emacs I need to run M-x run-python so the ELPY RPC process can use it (I believe), is there a way to automatically start this up?

[yitang]

emmmmm. I always have a running Python process when I edit/browser Python scrip, if there's not one, I'd hit c + RET to start one, this would solve the problem.

there are ways to automatically call run-Python but I am not sure this is a good idea in practise. plz check with the author, maybe open a new issue?

Best wishes,

Yi Tang

Big thanks for all the help!

Nice to see this was handled even without me looking, thanks a lot! :-)

Just a quick note:

Elpy's RPC process is completely unrelated to the Python shell start with M-x run-python. You do not need to do M-x run-python to use anything in Elpy.

hey @jorgenschaefer, that's awesome, thanks for letting us know!
