Bootstrap a new Ruby gem in less than a minute.


Bootstrapping a New Project

  1. Clone the master branch of this repository with
   $ git clone --single-branch new-ruby-gem
   $ cd new-ruby-gem

Optionally, reset to the latest release with

   $ git reset --hard ruby-gem-v2.0.1
  1. Run
   $ ./

and follow the prompts. This will replace the boilerplate, delete itself, and stage changes for commit. This script assumes the project repository will be hosted on GitHub. For an alternative location, you must update the URLs manually.

  1. Fill in the README Description section.

  2. If choosing a license other than the one provided: update LICENSE.txt, the README License section, and the gemspec file with your chosen license.


If you want to pull in future updates from this skeleton, you can fetch and merge in changes from this repository.

If this repository is already set as origin, rename it to upstream with

$ git remote rename origin upstream

and then configure your origin branch as normal.

Otherwise, add this as a new remote with

$ git remote add upstream

You can then fetch and merge changes with

$ git fetch upstream
$ git merge upstream/master


Note that is just a template for this skeleton. The actual changes for this project are documented in the commit history and summarized under Releases.


Add this line to your application's Gemfile

gem 'makenew-ruby_gem'
