ruby - rbenv irb history is not saving

Question

I install ruby via rbenv-installer.

When I use irb console, I can use history by pressing up and down on keyboard. And when I exited from console and start it again, I can't use prewious history. When I press up-arrow-button, nothing was happened.

When I used rvm this option was working. How can I switch on it in rbenv?

Answer 1

I found this way for solving my problem. In file ~/.irbrc write:

require 'irb/ext/save-history'
#History configuration
IRB.conf[:SAVE_HISTORY] = 100
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history"
