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"

Adding just the IRB.conf[:SAVE_HISTORY] = 10000 line was sufficient to fix things for me. – Sourdine

If this doesn't work, and you are on OS X, you may need to update your Readline library. See #37848322 – Demineralize

I had the same issue on OS X that @EvanPon described. I had to update my Readline library and reinstall Ruby via rbenv. See the post he linked for details. – Discard

This doesn't work for me, in Ubuntu 14.04. I know that ~/.rbrc is being processed because I put a puts at the top. But it just doesn't make any difference. I have Readline installed - at least, I can do Readline in the console. – Druse

Answer 2

Create ~/.irbrc if it does not exist, and add the following line to it:

IRB.conf[:SAVE_HISTORY] = 1000

Sufficient for me (ruby 2.2). History gets saved automatically to ~/.irb_history – Skysail
