How can I configure IPython 5 to have IPython 3's readline, tab-completion, (lack-of) syntax highlighting, etc? (self.IPython)

Question

I know at some point I may want to "upgrade", but for now I just want the old look & feel back.

I know IPython is very configurable but I'm not having much luck finding the correct settings.

(This only refers to IPython's interactive terminal, by the way)

Answer 1

Start by creating a default iPython profile. From your shell, type:

$ ipython profile create

That should give output similar to this, assuming the username someuser:

[ProfileCreate] Generating default config file: u'/home/someuser/.ipython/profile_default/ipython_config.py'

Open the newly created file with your favorite text editor, in the above example shown as: /home/someuser/.ipython/profile_default/ipython_config.py

Add the following lines at the bottom:

c.TerminalInteractiveShell.colors = 'NoColor'
c.TerminalInteractiveShell.display_completions = 'readlinelike'

Save the file.

That should be it. Changes should be active in new iPython sessions.
