Guide for creating and editing generators.
Step 1: create command for calling generator
Add command for generator in lib/blueprint/generator/cli.rb
.
Example:
command :new do |c|
c.syntax = 'blueprint new APP_PATH'
c.summary = 'Generate rails application'
c.description = 'Generate rails application with default settings and dependecies'
c.action do |args, _options|
Blueprint::Generator::RailsApp.new(name: args[0]).run!
end
end
Step 2: Create generator class
Extending class of Blueprint::Generator::Base
:
require 'blueprint/generator/base'
module Blueprint
module Generator
class RailsApp < Base
end
end
end
Step 3: Create folder with files
Create folder for files and templates for your application on folder lib/blueprint/generator/templates/
and override folder name on generator class
def self.template_path
'rails_app'
end
Step 4: Create ask question step for generator
Override ask_questions
method for creating config
hash. Question list.
def ask_questions
config[:bootstrap] = agree("Would you like initialize bootstrap on your application?")
end
Step 5: Create generator script
Override execute
method for creating generator script.
def execute
shell "rails new #{name} --skip-bundle --database=postgresql --no-rc --skip-test-unit"
end
