How do I make vi editing-mode work in IRB when using RVM?

Question

I "set editing-mode vi" in my .inputrc on my Mac OS system, which allows vi editing in IRB. When I'm using a RVM Ruby, the IRB sessions don't process this directive.

Does anyone know a solution?

Answer 1

Have you got set -o vi set, either at the command-line or in one of your startup scripts? That turns it on for the shell. I have both "set editing-mode vi" and set -o vi and have Vi-like editing in IRB.

EDIT:

Try creating ~/.editrc, put bind -v in it. Snow Leopard has support for editline built in, so that might be what IRB is using.

Try man 5 editrc for more info.

Answer 2

As mentioned before, you can add bind -v in your ~/.editrc.

The problem with this, as you may or may not have noticed is that this removes your ability to use tab completion. If you want to keep tab completion you can add: bind \\t rl_complete to your ~/.editrc.

Answer 3

These days, I'm using rbenv-installed Ruby 2.5 on MacOS Mojave and the way to get vi key bindings in irb is to add set editing-mode vi to ~/.inputrc.

It appears that adding bind -v to ~/.editrc isn't required and doesn't help.
