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

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 a开发者_JAVA技巧nyone know a solution?

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.

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.

Using RVM-installed Ruby 1.9.3 on Mountain Lion, I was able to get vi key bindings in irb by adding bind -v to ~/.editrc . I installed Ruby 2.0 using RVM on the same system and irb was stuck in emacs mode. Adding set editing-mode vi to ~/.inputrc got vi key bindings working in irb on Ruby 2.0 for me.

---

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.

I'm on BigSur (11.1) and observe this

• If using native ruby - edit ~/.editrc to add in 'bind -v'
• If using RVM built ruby - edit ~/.inputrc and add 'set editing-mode vi'

So you have to do both to make sure. A method does not work for the other

IRB (interactive Ruby shell) uses the Readline utility for line-editing capabilities.

Readline comes with a set of default keybindings. You can change these in the inputrc file. The location of this file defaults to ~/.inputrc.

When IRB starts up, the inputrc file is read, and the key bindings are set.

To use vim editing mode add the following to your ~/.inputrc

set editing-mode vi
set keymap vi-command

Please consult the documentation for other useful configuration options and where to put them.
