Ruby Here Documents - "squiggly"

Today I learned that ruby 2.3.0 has released the “squiggly” heredoc <<~HEREDOC, like:

sql = <<~SQL
SELECT *
FROM users
WHERE users.status = 'active'
SQL

ActiveRecord::Base.connection.execute(sql)
  • <<HEREDOC => plain text
  • <<-HEREDOC => plain text, may indent the closing identifier
  • <<~HEREDOC => plain text, could indent the content
