> Terminal color capabilities detection.

**TTY::Color** provides independent color support detection component for [TTY](https://github.com/piotrmurach/tty) toolkit.

## Installation

Add this line to your application's Gemfile:

```ruby

gem "tty-color"

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install tty-color

## Usage

**TTY::Color** allows you to check if terminal supports color:

```ruby

TTY::Color.color?    # => true

TTY::Color.support?  # => true

```

You can also get the number of colors supported by the terminal using `mode` method:

```ruby

TTY::Color.mode # => 64

```

To detect if color support has been disabled with `NO_COLOR` environment variable, use `disabled?`:

```ruby

TTY::Color.disabled? # => false

```

**TTY::Color** is just a module hence you can include it into your scripts directly:

```ruby

#!/usr/bin/env ruby

include TTY::Color

puts color?

```

## Command line tool

[tty-color-cli](https://github.com/piotrmurach/tty-color-cli) is a command line tool for the **TTY::Color**.

To check if terminal supports colors use `-s|--support`:

```bash

tty-color -s

tty-color --support

# => true

```

And to check color mode use `-m|--mode` option:

```bash

tty-color -m

tty-color --mode

# => 256

```

## 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.

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).
