How to log pyexcel

When developing source plugins, it becomes necessary to have log trace available. It helps find out what goes wrong quickly.

The basic step would be to set up logging before pyexcel import statement.

import logging
import logging.config
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
    level=logging.DEBUG)

import pyexcel

And if you would use a complex configuration, you can use the following code.

import logging
import logging.config
logging.config.fileConfig('log.conf')

import pyexcel

And then save the following content as log.conf in your directory:

   [loggers]
   keys=root, sources, renderers

   [handlers]
   keys=consoleHandler

   [formatters]
   keys=custom

   [logger_root]
   level=INFO
   handlers=consoleHandler

   [logger_sources]
   level=DEBUG
   handlers=consoleHandler
   qualname=pyexcel.sources.factory
   propagate=0

   [logger_renderers]
   level=DEBUG
   handlers=consoleHandler
   qualname=pyexcel.renderers.factory
   propagate=0

   [handler_consoleHandler]
   class=StreamHandler
   level=DEBUG
   formatter=custom
   args=(sys.stdout,)

   [formatter_custom]
   format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
   datefmt=


Disable logging
-------------------

In unit testing and django framework, you will find the `lml` logging even you have not
explicitly wanted them.


You can suppress them:

  import logging
  logging.getLogger('lml.plugin').propagate = False

Here is a list of possible modules: `lml.plugin` and `lml.loader`.
