Get VI bindings in IEX (Elixir REPL)
# VI bindings in iex:
brew install rlwrap # on OSX
echo "alias iex='rlwrap -a foo iex'" >> ~/.bash_profile
echo "set editing-mode vi" >> ~/.inputrc
source ~/.bash_profile
# To run iex WITHOUT rlwrap
\iex
# Note
You cannot have vi bindings through rlwrap AND command completion at the same time.
The author of rlwrap explains the reason here: http://stackoverflow.com/questions/9210931/is-there-a-way-of-running-rlwrap-with-tab-completion-disabled

What is the foo?

The -a switch tells rlwrap to 'always remain in readline mode'. On OSX the -a option requires an argument, in this case a dummy argument foo.

On unbuntu, this worked for me.
