Scrapy framework - Colorize logging

Vote count: 0

I am trying to make Scrapy output colorized logs. I am not so familiar with Python logging, but my understanding is that I must make my own Formatter and make it use by Scrapy. I succeeded in making a Formatter to colorized the output using Clint.

My problem is that I can't make it work within Scrapy correctly. I would have expected the logger object in my spider to have a handler, then I would have switched the formatter of that handler. When I looks what is inside spider.logger.logger, I see that handler is an empty list. I tried to add my formatter in a new stream handler doing.

crawler.spider.logger.logger.addHandler(sh) where sh is a handler using my color formatter.

This add for effect to make scrappy output each messages twice. First message is colorized but doesn't have Scrapy formatting. The second one has Scrapy formatting with no colors.

How can I make Scrapy output colorized logs keeping the same format that can be set in settings.py

Thanks
