So, the way Rails does it is by making a specific Ruby script the "waypoint" of the application- I can't remember if it's config/environment or config/application- but the Rails root is relative to its FILE. For instance, in a Rails application, place the Gemfile in the same directory as the Rakefile.. Syntax. It also builds any native extensions (compiled C code). A file named lib/awesome_gem/parser.rb would be required as require "awesome_gem/parser" from anywhere inside the gem.

Now I see that I have two versions installed: I can see which version is being used with: This listed a file in the directory domain_name-0.5.20170404, so the version is 0.5.20170404. Gem::Version for version dependency notes. class Gem::BasicSpecification BasicSpecification is an abstract class which implements some common code used by both Specification and StubSpecification.. Let’s say I have two files, foo.rb and bar.rb in /Users/cstack, In a different directory, say / I start up irb and load foo.rb, foo.rb is loaded just fine because I gave it an absolute path. setup (:default,:ci) require 'nokogiri' Learn More: Groups . Class methods (3) new (>= v2_6_3); provides? The require keyword searches for the dependencies in the array $LOAD_PATH and tries to load it for the file that has a dependency on certain library. For instance, in a Rails application, place the Gemfile in the same directory as the Rakefile. Now, the exact location of the source root folder is stored in the libx variable which is then pushed into the $LOAD_PATH array. If you have been using gems or built-in libraries, loading dependencies with require just works fine in most of the cases. RubyGems is the Ruby standard for publishing and managing third party libraries. So RubyGems will give me the more recent version if I require domain_name. A Gemfile looks like this: ruby '2.5.0' gem 'rails', '~> 5.2.1' gem 'sqlite3' gem 'puma', '~> 3.11' gem 'bootsnap', '>= 1.1.0', require: false One of the big drawbacks with a SQLite database is that there is a global write-lock.

So, here we have a lib folder at the root and a test folder that checks if the code in the lib directory is working properly. If '-' is given for path RubyGems searches up from the current working directory for gem dependency files (gem.deps.rb, Gemfile, Isolate) and activates the gems in the first one found. This is not recommended, but I'm writing this section to load RBS files for other tools which doesn't support this feature yet. run@desktop:~/mir/ruby$ → ruby -e 'p require "nokogiri"' true run@desktop:~/mir/ruby$ → ruby -e 'autoload(:N, "nokogiri"); p N' -e:1:in `
