This is a IPython client for Neovim, based on ivanov/vim-ipython, but refactored for nvim's plugin architechture and improved async event handling. It is not as feature-complete as vim-ipython, but it has better support for long-running commands that continously produce output, for instance this silly example:

from time import sleep
for i in range(10):
    sleep(0.5)
    print(i)

Another difference, :IPython <args> is interpreted the same as the command line ipython console <args>, for instance:

Start new python kernel: (on IPython2.x, python3 is supported through a hack that assumes python3 is in $PATH )

:IPython
:IPython3

Connect to existing kernel:

:IPython --existing

Start kernel in different language (if installed).

:IPython --profile julia
:IPython --profile haskell

this will be better supported in IPython 3.x (Jupyter)

See plugin/ipy.vim for keybindings (you might want to override these)
