# IRB
IRB stands for "interactive Ruby" and is a tool to interactively execute Ruby expressions read from the standard input.
The `irb` command from your shell will start the interpreter.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'irb'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install irb
## Usage
Use of irb is easy if you know Ruby.
When executing irb, prompts are displayed as follows. Then, enter the Ruby expression. An input is executed when it is syntactically complete.
```
$ irb
irb(main):001:0> 1+2
#=> 3
irb(main):002:0> class Foo
irb(main):003:1> def foo
irb(main):004:2> print 1
irb(main):005:2> end
irb(main):006:1> end
#=> nil
```
The Readline extension module can be used with irb. Use of Readline is default if it's installed.
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
