How can I automatically set an IRB configuration across all environments for a specific Ruby on Rails application?

I'd like to set an IRB configuration across an application (all environments, including production), so I don't have to run it every time I use the Ruby on Rails console. The specific configuration isn't that important, but it's:

IRB.conf[:USE_PAGER] = false

What I've tried

I thought it would be as simple as:

# config/initializers/console.rb
Rails.application.console do
  IRB.conf[:USE_PAGER] = false
end

but when I open the Ruby on Rails console

IRB.conf[:USE_PAGER]
# => true

confirming that it hasn't set (or was set but was overridden).

Note

• I considered using a ~/.irbrc file, but that wouldn't work across multiple machines (e.g., the configuration should be applied in production, not just locally)
  • I notice someone asked how to include .irbrc in the application itself. When I attempted the answer, my *bin directory doesn't have a file called console (just bundle, dev, rails, rake, or setup)

You can add .irbrc into your project. There are multiple locations that a configuration file can be loaded from, including the current directory, which can be your project. Although, the documentation says "a configuration file", all the files found will be loaded:

IRB searches for a configuration file in the following order:

• $IRBRC
• $XDG_CONFIG_HOME/irb/irbrc
• $HOME/.irbrc
• $HOME/.config/irb/irbrc
• .irbrc in the current directory
• irb.rc in the current directory
• _irbrc in the current directory
• $irbrc in the current directory
