I understand that because Ipython 5.0.0 uses a new input library (prompt_toolkit) it no longer defaults to the editor mode specified in .inputrc (*nix). This option has to be set in an Ipython profile configuration file (see http://stackoverflow.com/a/38329940/2915339).
My question is: having set vi-mode in the profile configuration file, how does one specify a particular keybinding? I like to use 'jk' for escape, for instance.
.inputrc. There does not seem to be a way to define custom keybindings for the
vi mode in the IPython 5.0.0 profile configuration file.
Here's workaround I'm currently using. It's not pretty, but it works for now.
According to the IPython docs, you can specify Keyboard Shortcuts in a startup configuration script.
Instead of rebinding
ESC, I'm making a unicode "j" (
u'j') followed by a unicode "k" (
u'k') inside of
VimInsertMode() a shortcut for a
prompt_toolkit event that switches to navigation mode.
I created a
.ipython/profile_default/startup/keybindings.py with the following code:
from IPython import get_ipython from prompt_toolkit.enums import DEFAULT_BUFFER from prompt_toolkit.filters import HasFocus, ViInsertMode from prompt_toolkit.key_binding.vi_state import InputMode ip = get_ipython() def switch_to_navigation_mode(event): vi_state = event.cli.vi_state vi_state.reset(InputMode.NAVIGATION) if getattr(ip, 'pt_cli'): registry = ip.pt_cli.application.key_bindings_registry registry.add_binding(u'j',u'k', filter=(HasFocus(DEFAULT_BUFFER) & ViInsertMode()))(switch_to_navigation_mode)
The prompt_toolkit source will help you implement other shortcuts as needed.
