Gem-Licenses

Gem-licenses is an attempt to collect license information from project's gems. Similar to 3licenses.

Motivation

The overwhelming majority of 3rd party licenses require the application that uses them to reproduce the license verbatim in an artifact that is installed with the application itself. For instance, the BSD license states the following.

“Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution.”

Are you currently copying individual license.txt files "by hand" or are you including license text in your documentation with copy/paste? This project aims at improving this situation.

Usage

Include gem-licenses in your project's Gemfile.

group :development, :test do
  gem 'gem-licenses'
end

Install Rake tasks from Rakefile.

require 'rake'
require 'gem-licenses'
Gem::GemLicenses.install_tasks

To list licenses try the following Rake task.

rake gem:licenses

To write a CSV file of gems + licenses.

rake gem:licenses:csv['licenses.csv']
