Como criar uma gem ruby?

Escolhi tratar sobre esse assunto hoje simplesmente porque foi uma das primeiras coisas que me perguntei "como eu faço isso?" no mundo ruby. Acredito que muita gente se pergunte a mesma coisa e espero que eu possa ajudar em algo para elas. 😀

O que é uma gem?

Bem, se você é um programador java, você chama sua gem de jar, se você é um programador C#, você chama de dll. Resumindo, é uma lib, uma biblioteca contendo códigos que você pode reaproveitar importando em outros projetos.

E usar gems no ruby é muito fácil, se você já deu uma brincada com rails por exemplo, é só você adicionar o código gem 'nome_da_gem' no arquivo Gemfile que está no root, depois executar o comando bundle install para baixar sua gem do repositório e pronto, só sair usando a biblioteca!
