Requirements

  1. A UNIX-based system.
  2. MRI 2.x.x.
  3. RubyGems.
  4. Bundler.

Setup

For a secure install, type the following from the command line (recommended):

gem cert --add <(curl -Ls https://www.alchemists.io/gem-public.pem)
gem install gemsmith --trust-policy MediumSecurity

NOTE: A HighSecurity trust policy would be best but MediumSecurity enables signed gem verification while allowing the installation of unsigned dependencies since they are beyond the scope of this gem.

For an insecure install, type the following (not recommended):

gem install gemsmith

You can configure common settings for future gem builds by creating the following file:

~/.gemsmith/settings.yml

...using the following settings (for example):

---
:author_name: Joe Smith
:author_email: [email protected]
:author_url: https://www.smithware.com
:company_name: Smithware

If no options are configured, then the defaults are as follows:

gem_platform: Gem::Platform::RUBY
gem_private_key: ~/.ssh/gem-private.pem
gem_public_key: ~/.ssh/gem-public.pem
author_name: <git name>
author_email: <git email>
author_url: https://www.unknown.com
gem_url: <author URL>
company_name: <author name>
company_url: <author URL>
github_user: <github user>
year: <current year>
ruby_version: 2.2.0
rails_version: 4.2

Usage

Command Line Interface (CLI)

gemsmith -c, [create=CREATE]  # Create new gem.
gemsmith -e, [--edit]         # Edit Gemsmith settings in default editor.

gemsmith -o, [open=OPEN]      # Open a gem in default editor.
gemsmith -r, [read=READ]      # Open a gem in default browser.
gemsmith -v, [--version]      # Show Gemsmith version.

For more gem creation options, type: gemsmith help create

Rake

Once a gem skeleton has been created, the following tasks are available within the project via Bundler (i.e. rake -T):

rake build                 # Build example-0.1.0.gem into the pkg directory
rake clean                 # Clean gem artifacts
rake install               # Build and install example-0.1.0.gem into system gems
rake install:local         # Build and install example-0.1.0.gem into system gems without network access
rake publish               # Build, tag v0.1.0 (signed), and push example-0.1.0.gem to RubyGems
rake readme:toc            # Update README Table of Contents
rake release               # Create tag v0.1.0 and build and push example-0.1.0.gem to Rubygems
rake rubocop               # Run RuboCop
rake rubocop:auto_correct  # Auto-correct RuboCop offenses
rake spec                  # Run RSpec code examples

Upgrades

For those upgrading from Gemsmith 5.3.0 and wanting to use the new Rake tasks, do the following:

  • Edit your gemspec and add the following dependency: spec.add_development_dependency "gemsmith".
  • Edit your Rakefile and remove the Bundler requirement require "bundler/gem_tasks" and replace it with the Gemsmith tasks: require "gemsmith/rake/setup". Don't worry, this includes the Bundler tasks too.

Tests

To test, run:

bundle exec rake

Security

Git Signing Key

To sign your Git tags, start by installing and configuring GPG:

brew install gpg
gpg --gen-key

When setting up your GPG key, here is an example of safe defaults:

  • Key kind: RSA and RSA (default)
  • Key size: 4096
  • Key validity: 0
  • Real Name: <your name>
  • Email: <your email>
  • Passphrase: <your passphrase>

To obtain your key, run the following and take the part after the forward slash:

gpg --list-keys | grep pub

Add your key to your global Git configuration in the [user] section. Example:

[user]
  signingkey = <your GPG key>

Now, when publishing your gems with Gemsmith (i.e. bundle exec rake publish), signing of your Git tag will happen automatically. Should you not want to sign your tags, use bundle exec rake release which is the same as bundle exec rake publish except the Git tag is not signed.

Gem Certificates

To create a certificate for your gems, run the following:

cd ~/.ssh
gem cert --build [email protected]
chmod 600 gem-*.pem

The resulting *.pem keys can be referenced via the *gem_private_key- and *gem_public_key- settings mentioned in the Setup documentation.

To learn more about gem certificates, read the following:

Promotion

Once your gem is released, you might like to let the world know about the new awesomeness. Here are several resources:

Versioning

Read Semantic Versioning for details. Briefly, it means:

  • Patch (x.y.Z) - Incremented for small, backwards compatible bug fixes.
  • Minor (x.Y.z) - Incremented for new, backwards compatible public API enhancements and/or bug fixes.
  • Major (X.y.z) - Incremented for any backwards incompatible public API changes.
