Gems on Ruby
2 likes1,880 views
1. The document discusses RubyGems, Bundler, and rbenv/ruby-build. It provides an overview of each tool's purpose and history. 2. RubyGems is the package manager for Ruby libraries. Bundler is a tool for managing dependencies of Ruby applications. Rbenv/ruby-build allow managing multiple Ruby versions and building Ruby. 3. The document outlines plans to further integrate RubyGems and Bundler, but notes Bundler 2 has not yet been released, which is needed for full integration. Security improvements have also been made to RubyGems.

- 8. Answer • Must buy “Web+DB Press Vol.103” • You should use RubyGems/Bundler/ rbenv at all.

- 11. • gemcutter.org: • https://github.com/rubygems/gemcutter • You can use `gem yank` command after you did invoke `gem i gemcutter`. • rubygems.org: • gemcutter.org was renamed to rubygems.org. • bundler: • 2010: Released to 1.0.0 version. Packaging and Disribution(2)
- 12. RubyGems 2.
- 13. • The package manager of Ruby libraries. • `gem install rails -v “~> 5.2”` • You can install specified version of Ruby libraries that called `Gem`. RubyGems handles global environment on your box. • You could specify `gem ‘rails’, ‘~> 5.2’` syntax without its dependency. What’s rubygems?
- 14. What does mean “official”? “official” means “Matz controllable” Un-controllable examples: • ruby-doc.org • rubygems.org • bundler.io • Ruby version manager(rvm/rbenv/chruby) “RubyTogether” maintains RubyGems, Bundler and RubyGems.org(Rails Application).
- 15. • Merge latest stable version into Ruby Core • Ruby 2.6.0 will bundle RubyGems 3.0(TBD) • Ruby 2.7 or 3.0 will bundle RubyGems 4.0(TBD) The policy of RubyGems versioning
- 16. • RubyGems have HackerOne project. • 3 people handle vulnerability issues. • But We have no workflow about security release. • RubyGems 2.7.6 was accidentally released. Security
- 17. Bundler 3.
- 18. • The vendoring tool of Ruby. • RubyGems couldn’t care dependency of Ruby libraries and isolate version managing with ruby process. • Bundler can do them with `Gemfile` What’s bundler? # frozen_string_literal: true source "https://rubygems.org" git_source(:github) { |repo| "https://github.com/#{repo}.git" } gemspec # We need a newish Rake since Active Job sets its test tasks' descriptions. gem "rake", ">= 11.1"
- 19. • RubyGems 2.x, 3.x uses Molinillo-0.5.7 • Bundler 1.16.x also uses Molinillo-0.6.4 • These are different versions and behavior of dependency resolver. Dependency Resolver incompatible ~/D/g/r/rubygems (master) > ls lib/rubygems/resolver/molinillo/lib/molinillo delegates dependency_graph.rb gem_metadata.rb resolution.rb state.rb dependency_graph errors.rb modules resolver.rb ~/D/g/b/bundler (master) > ls lib/bundler/vendor/molinillo/lib/molinillo compatibility.rb dependency_graph errors.rb modules resolver.rb delegates dependency_graph.rb gem_metadata.rb resolution.rb state.rb
- 21. • The Ruby version manager (not ruby library) • The Ruby language will be released Dec.25 every year. You need to take care ruby versions in your box like Ruby 2.3, 2.4, 2.5… • Ruby isolates library locations used by Ruby versions. • rbenv(and ruby-build) provides an environment that makes version switching and its build definitions. What’s rbenv?
- 22. Version number and release cycle We plan to release every Christmas day. • 2.1.0: 2013/12/25 • 2.2.0: 2014/12/25 • 2.3.0: 2015/12/25 • 2.4.0: 2016/12/25 • 2.5.0: 2017/12/25 • 2.6.0: 2018/12/25(TBD) • … • 3.0.0: 2020/xx/xx

- 28. • We can use Keywords argument, Refinement, Other cool features in RubyGems now. • Simple build matrix Only support Ruby 2.2+
- 29. • It has non-compatible features. • Make enable as default for conservative option. • Behaviour changes with default gems installer. • Executables in bin folder conflict with their gem versions. • Make ruby gem install to user-install by default. RubyGems 4
- 30. • We got the installation time when already installed gems. • To use conservative is ignore re-install action. Make conservative option as default ~ > gem i rails clone http://rubyonrails.org -> /Users/hsbt/Documents/rubyonrails.org git ls-remote http://rubyonrails.org hg identify http://rubyonrails.org svn info http://rubyonrails.org error Could not find version control system: http://rubyonrails.org exists /Users/hsbt/Documents/github.com/rails/rails Successfully installed rails-5.2.0 1 gem installed ~ > gem i rails —conservative ~ >
- 31. • Rubygems 4 will install the all gems to `~/.gem` • Pros: Ruby in linux distribution has many of FAQ for gem installation for using `sudo`. This change resolve this issues. • Cons: Ruby version manager like rbenv is not support it. And This is big incompatible feature. Make `--user-install` as default
- 33. • We are working to integrate RubyGems and Bundler. • But It’s still working progress status because there is no plan to release Bundler 2. • RubyGems 3&4 drop to support under the Ruby 2.2. Because Bundler 1.x still supports Ruby 1.8 and 1.9. • I’m waiting to release Bundler 2 for this integration. RubyGems/Bundler integration
- 34. • Bundler was located rubygems repository as git submodule Bundler Integration(rubygems.rb) if USE_BUNDLER_FOR_GEMDEPS ENV["BUNDLE_GEMFILE"] ||= File.expand_path(path) require 'rubygems/user_interaction' Gem::DefaultUserInteraction.use_ui(ui) do require "bundler" @gemdeps = Bundler.setup Bundler.ui = nil @gemdeps.requested_specs.map(&:to_spec).sort_by(&:name) end else rs = Gem::RequestSet.new @gemdeps = rs.load_gemdeps path rs.resolve_current.map do |s| s.full_spec.tap(&:activate) end end
