Use Vi keys in sage console

asked 2016-09-17 15:54:01 +0100

I wish to have the sage console use the vi-style editing keys instead of the default emacs ones. I have configured IPython to do this already, but sage does not respect this option. Any help would be appreciated.

Sage uses its own version of ipython with its own startup files. Those startup files should be under $DOT_SAGE/ipython-X.Y.Z/ ; so for me, the interesting directory is in ~/.sage/ipython-5.0.0/profile_default/ . There was no ipython_config.py file in there, so I copied it from the .ipython directory.

So here is what I did to get vi keybindings to work:

Get vi keybindings to work in ipython by adding the line c.TerminalInteractiveShell.editing_mode = 'vi' to .ipython/profile_default/ipython_config.py
cp -n ~/.ipython/profile_default/ipython_config.py ~/.sage/ipython-5.0.0/profile_default/

If you don't have the ipython_config.py file, you can create it with > ipython profile create [profilename] in the terminal. It will also populate the file with all possible options including vi mode. (And thank you @Eigentime, it solved it for me)
