> Terminal screen size detection which works on Linux, OS X and Windows/Cygwin platforms and supports MRI, JRuby and Rubinius interpreters.

**TTY::Screen** provides independent terminal screen size detection component for [TTY](https://github.com/piotrmurach/tty) toolkit.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'tty-screen'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install tty-screen

## 1. Usage

**TTY::Screen** allows you to detect terminal screen size by calling `size` method which returns [height, width] tuple.

```ruby
TTY::Screen.size     # => [51, 280]
```

To read terminal width do:

```ruby
TTY::Screen.width    # => 280
TTY::Screen.columns  # => 280
TTY::Screen.cols     # => 280
```

Similarly, to read terminal height do:

```ruby
TTY::Screen.height   # => 51
TTY::Screen.rows     # => 51
TTY::Screen.lines    # => 51
```
