Simple but customize captcha generator( image + voice )
Project description
Light were, flexible and customize logging tools. Threads and processes safely! Package has many default preset to use after installation. But if you need customize your own logger, basic classe make you life better. Smart decorators help you logging your methods on code and catch errors. Event handler help you connect your handler and send notification on specific events. Message and field as Model, create you own generic fields, messages, and format. Configurate multy logger and handle another formats and levels from one instance.
Curently avaible
Loggers presets * Console Logger * File Logger * JSON Logger
Programs * Pipe handler
Console Logger
Debug and monitoring you applications via pretty console logging.
