Reference

You can take this plugin as vim-slime + vim-ipython-cell

But there are some difference:

• only support vim-terminal(neovim or vim8) REPL, not screen, tmux , etc.
• auto start REPL by <Alt-Enter>, and no care console-window is right or bottom.
• diff protocol of cell:

                                   _
a | import numpy as np              | cell 1
  |                                _|
b | numbers = np.arange(10)         | cell 2
  |                                 |
  |                                _|
c | for n in numbers:               | cell 3
  |     print(n)                    |
  |     if n % 2 == 0:              |
  |         print("Even")           |
  |     else:                       |
  |         print("Odd")            |
  |                                _|
d | total = numbers.sum()           | cell 4
  | print("Sum: {}".format(total)) _|
