Classical workflow is to use:

• official Ruby distribution
• Bundler to manage dependencies

Installation¶

Windows¶

1. Download and run Ruby installer
   • use the versin with DevKit
2. at the end, a command prompt will open, confitm the prompt with Enter

Project setup¶

The project configuration is stored in the Gemfile file. It contains a list of dependencies, which are installed using the bundle command. Typically, the file contains the following lines:

source "https://rubygems.org" # the source of the gems

gem "jekyll" # the gem to install

Gems¶

Gems are packages for Ruby. They can be installed using the gem command, but moslty, they are installed as dependencies using the bundle command.
The gem specification in the Gemfile contains the following parameters (split by spaces):

• gem: the name of the gem (required)
• version: the version of the gem
• group: the group of the gem. It can be used run a command only for a specific group. For example, bundle install --without development will not install gems from the development group.

The group parameter is a new syntax, the old syntax is to use the group command:

group :development do
  gem "jekyll"
end
