Why?

This is a pet project. I like ruby and text-based applications, so I combined them.

Installation

Add this line to your application's Gemfile:

gem 'text_chart'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install text_chart

Usage

This snippet will generate the text chart at the top of the readme.

TextChart.new(
  "text_chart demonstration",
  "Show you how cool this is",
  [17, 54, 47, 64, 27, 56, 33, 66, 14, 45, 10, 21, 24, 27, 73, 54, 20, 67, 44, 5]
).to_s

You can enable colors:

TextChart.new(
  "text_chart demonstration",
  "Show you how cool this is",
  [17, 54, 47, 64, 27, 56, 33, 66, 14, 45, 10, 21, 24, 27, 73, 54, 20, 67, 44, 5],
  true
).to_s

Limitations

Right now TextChart only supports positive integers.

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 the created tag, and push the .gem file to rubygems.org.
