最方便最好看最好用的python日志。

这个日志没有依赖自己的其他包，复制即可运行，也可以从pypi网站上下载或者pip来安装这个日志。

1、日志内置了7种模板，其中模版4和模板5，可以实现点击日志跳转到指定文件指定行数的功能，史无前例的实现这种方式。

2、使用了ColorHandler作为默认的控制台显示日志，而不是使用官方的StramHandler，实现五颜六色的日志，在茫茫大海的日志中一眼就能看出哪些是调试日志，哪些是错误日志哪些是警告日志和严重日志。绿色代表debug，天蓝色代表info，黄色代表warning，粉红色代表错误，血红色代表严重错误，颜色符合正常逻辑，具体的颜色显示业余自己设置的pycharm主题和配色有关，建议使用黑色主题，具体的颜色显示与pycahrm版本也有一些关系。

3、实现了进程安全的日志切片，引用的是第三方的Handler

4、添加了对国内邮箱 qq 163等支持的mailhandler，并且支持邮件发送控频。

5、添加了MongoHanler，可以自动拆分日志字段插入mongo

6.1、以上这些handler都不需要去手动调用添加各种handler，都是通过传参的方式，如，设置了文件名那么自动生成文件日志，添加了mongo的url登录链接，则添加mongohandler，以此类推。

6.2、要搞清楚为啥logger和各种handler，要弄清楚日志命名空间，各种handler的关系和logger的关系必须弄清楚23种设计模式的观察者模式，搞清楚这个模式了，就可以自己扩展各种各样的handler来满足自己的需求。

为什么要使用日志呢，

之前同事全部print，十分蛋疼，项目有几十万行，一运行起来，各种地方嵌套import各种模块，到处去print，十分操蛋，完全不知道哪里冒出来的日志，不好禁止，扩展不了各种handler，总之比日志差太多了。。

拿print当做日志用是属于py很初级的表现。

这个很长，是加了很多种handler，和同类型handler自动去重。

简化版的是打猴子补丁自动变彩，不需要使用这个日志了。

猴子补丁的应用，猴子补丁来改变日志。

"""
日志管理，支持日志打印到控制台和写入切片文件和mongodb和email和钉钉机器人和elastic和kafka。
使用方式为  logger = LogManager('logger_name').get_and_add_handlers(log_level_int=1, is_add_stream_handler=True, log_path=None, log_filename=None, log_file_size=10,mongo_url=None,formatter_template=2)
或者 logger = LogManager('logger_name').get_without_handlers(),此种没有handlers不立即记录日志，之后可以在单独统一的总闸处对所有日志根据loggerame进行get_and_add_handlers添加相关的各种handlers
创建一个邮件日志的用法为 logger = LogManager.bulid_a_logger_with_mail_handler('mail_logger_name', mail_time_interval=10, toaddrs=('909686xxx@qq.com', 'yangxx4508@dingtalk.com',subject='你的主题)),使用了独立的创建方式
concurrent_log_handler的ConcurrentRotatingFileHandler解决了logging模块自带的RotatingFileHandler多进程切片错误，此ConcurrentRotatingFileHandler在win和linux多进程场景下log文件切片都ok.
1、根据日志级别，使用coolorhanlder代替straemhandler打印5种颜色的日志，一目了然哪里是严重的日志。
2、带有多种handler，邮件 mongo stream file的。
3、支持pycharm点击日志跳转到对应代码文件的对应行。
4、对相同命名空间的logger可以无限添加同种类型的handlers，不会重复使用同种handler记录日志。不需要用户自己去判断。
