Get VI bindings in IEX (Elixir REPL)

gistfile1.md

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
