Can I get the Ruby on Rails console to remember my command history, umm, better?
rails-console, ruby-on-rails-3
Solution
From How To – Persist Rails or IRB Console Command History After Exit.
Create, or edit your `~/.irbrc` file to include:
require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 200
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-history"
Problem
I'm using the console in Ruby on Rails 3.1.1, and I'm finding its command history (up arrow) to be really flaky. I've run the commands `p = Product.by_name 'Acme'` and `p.add_search_term('Snipe')` several times today, across several console sessions. Yet, when I reload the Ruby on Rails console, only the first one shows in my command history, not the second. Sometimes they are both there in the history after I reload the console. On top of that, I see commands in my history that are from several days ago after pressing up arrow only a few times. Is there some sort of configuration that I need to change or is this a bug? - Ruby on Rails 3.1.1` - Ruby 1.9.2p290` - Ubuntu 11.10`
