Use Pry as IRB replacement in rails 3 console

development.rb

# Add this to the end of your development.rb and add 
#
# gem 'pry'
#
# to your Gemfile and run bundle to install.

silence_warnings do
  begin
    require 'pry'
    IRB = Pry
  rescue LoadError
  end
end

@grosser FTW!

much obliged grosser, that worked great for me. No messing with the actual project source

I use following one-liner because it leaves irb command unchanged and bundle console runs whatever you have in Gemfile (eg. bundle console development). And use pry if you want repl without Gemfile.

echo "Pry.start || exit rescue LoadError" > ~/.irbrc

I use this in my zshrc:

pry () {
    if [ -e Gemfile.lock ] && [ -e ./config/environment.rb ] && grep -q pry Gemfile.lock
    then
        bundle exec pry -r ./config/environment "$@"
    else
        /usr/bin/pry "$@"
    fi
}

@grosser reload! doesn't work here using the alias. Any ideas?

@l0b0 see where reload! is defined and include this too or see what else gets included to irb

@13k thanks works great
