在Ruby中,优化方法定义可以从以下几个方面进行:
# 不推荐
def process_user_data_from_the_database_and_transform_it_into_a_report
# ...
end
# 推荐
def pdtat_u_r_d_b_t_r
# ...
end
module A
def self.method_name
# ...
end
end
module B
def self.method_name
# ...
end
end
A.method_name
B.method_name
class UserData
attr_accessor :name, :age, :email
end
def process_user_data(user_data)
# ...
end
user = UserData.new
process_user_data(user)
def process_items(&block)
items.each(&block)
end
process_items { |item| item * 2 }
MAX_RETRIES = 3
def retry_on_failure(retries = MAX_RETRIES)
# ...
end
module Logger
def self.included(base)
base.class_eval do
# ...
end
end
end
class MyClass
include Logger
# ...
end
# 使用Ruby内置方法
array.map(&:to_s)
# 使用Ruby内置库
require 'date'
today = Date.today
通过以上方法,可以在Ruby中优化方法定义,提高代码的可读性、可维护性和可扩展性。
