> Terminal screen size detection that works on Linux, macOS and Windows systems
and supports Ruby MRI, JRuby, TruffleRuby and Rubinius interpreters.
**TTY::Screen** provides a terminal screen size detection component for the
[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
Use the `size` method to detect terminal screen size. It will result in
a `[height, width]` array:
```ruby
TTY::Screen.size # => [51, 280]
```
Use the `width`, `columns` or `cols` method to detect terminal screen width:
```ruby
TTY::Screen.width # => 280
TTY::Screen.columns # => 280
TTY::Screen.cols # => 280
```
Use the `height`, `lines` or `rows` method to detect terminal screen height:
```ruby
TTY::Screen.height # => 51
TTY::Screen.lines # => 51
TTY::Screen.rows # => 51
```
## Development
After checking out the repo, run `bin/setup` to install dependencies.
Then, run `rake spec` to run the tests. You can also run `bin/console`
for an interactive prompt that will allow you to experiment.
