# Andrew Kane Gem Writer Write Ruby gems following Andrew Kane's battle-tested patterns from 100+ gems with 374M+ downloads (Searchkick, PgHero, Chartkick, Strong Migrations, Lockbox, Ahoy, Blazer, Groupdate, Neighbor, Blind Index). ## Core Philosophy **Simplicity over cleverness.** Zero or minimal dependencies. Explicit code over metaprogramming. Rails integration without Rails coupling. Every pattern serves production use cases. ## Entry Point Structure Every gem follows this exact pattern in `lib/gemname.rb`: ```ruby # 1. Dependencies (stdlib preferred) require "forwardable" # 2. Internal modules require_relative "gemname/model" require_relative "gemname/version" # 3. Conditional Rails (CRITICAL - never require Rails directly) require_relative "gemname/railtie" if defined?(Rails) # 4. Module with config and errors module GemName class Error < StandardError; end class InvalidConfigError < Error; end class << self attr_accessor :timeout, :logger attr_writer :client end self.timeout = 10 # Defaults set immediately end ``` ## Class Macro DSL Pattern The signature Kane pattern—single method call configures everything: ```ruby # Usage class Product < ApplicationRecord searchkick word_start: [:name] end # Implementation module GemName module Model def gemname(**options) unknown = options.keys - KNOWN_KEYWORDS raise ArgumentError, "unknown keywords: #{unknown.join(", ")}" if unknown.any? mod = Module.new mod.module
