Hirb and IRBTools

Updated: 31 Jul 2012

The Rails console makes it pretty hard to see whats going on when you dump a model. IRBTools includes Hirb which will format Active Record output into pretty tables. Unfortunately those tables don't resize with the console resizing, but on unixy systems like Linux and OSX you can do a little hack to fix that.

This is my .irbrc file. Some save-history settings and the Signal.trap, which will tell Hirb to resize when the terminal resizes:

1
2
3
4
5
6

require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 200
IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-history"

Signal.trap('SIGWINCH', proc { y, x = `stty size`.split.map(&:to_i); Hirb::View.resize(x, y) } )

This requires these handy gems in your Gemfile:

1
2
3

gem 'irbtools'
gem 'irbtools-more'
