Ipython completion in elpy

Question

My elpy uses ipython as the interactive interpreter. It does not, however, emulate ipython's history-informed autocomplete feature (for lack of a better term).

That is: within an ipython session launched from the terminal, if you want to execute a line previously executed, you can type the first part of the line, and up-arrow will only display consistent previous commands.

In the ipython shell launched from elpy (with C-c C-c), I can execute previous commands with C-p, but I cannot view only those commands consistent with a given partial command. How can I utilize this very useful feature of ipython within the emacs elpy shell?

Answer 1

I don't use eply, I use emacs 25.1.1 with company-jedi with the following:

(setq
 python-shell-interpreter "ipython3"
 python-shell-interpreter-args "--simple-prompt --pprint")

Inside emacs *Python*

Python 3.6.0, Anaconda 4.3.0, Ipython 5.1.0

In[1]: x = 10
In[2]: x = 125
In[3]: x =      # type M-p 

I get history items 1 and 2 and Input restored. That example seems to be working for me.

Please share what your emacs version, (I)python version and a code snippet. It may be useful to file a bug report with elpy if that is the problem.
