Well, zLOG is hopefully going away some time soon ;-)
You should really be using the python logging module, for which zLOG is
now just a facade:
import logging
logger = logging.getLogger('event.whatever')
logger.info('Argh! Help, the world with end in %i seconds',end_of_time)
I'm just writing a proposal to make this available in untrusted code
such as Script (Python)'s, but in the meantime, you can use an external
method:
import logging
logger = logging.getLogger('event.myapplogger')
def log(self,level,message,*args,exc_info=False):
logger.log(getattr(logging,level),
message,
*args,
exc_info = exc_info

Chris

[Zope] Write log file from script
I am looking for a simple strategy to write a debug log file from a python script. I used to have such a beast but somewhere in a shuffle it got lost -- and my brain seems to be dead this morning trying to figure it out. Anybody out there have something like this or a url explaining how to do it? ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Write log file from script
How about creating a string or list, then appending your debug info to the string/list, then returning the string/list to the calling routine which then displays the string/list?

Re: [Zope] Write log file from script
Depends upon what you want to do and how much access you have. For
debugging purposes I often use an external procedure
def debugWindow( data ):
fd = open('/tmp/debugWindow,'a')
fd.write( str(data))
fd.close()
and look at the output with
tail -f /tmp/debugWindow
Or, you can use the same approach to write to syslog using the Python
logging module
Or you can piggyback into the Zope logging mechanism--see the sources for
that exercise.
I find the external procedure approach to be useful in its simplicity

OK -- thanks to those that replied (many with a similar solution).
I do have access to the server (Win2000 in my case) so I can pretty well do anything I want.
It comes back now -- I did something like that but then called it through a gateway Python script that allowed me to turn off all logging in one spot easily (by modifying the script) in case I wanted to leave the debug statements there temporarily and not incur the expense of a huge log file.

Look at: Zope-2.8.1-home/lib/python/zLOG/__init__.py There are lots of examples of the use of the LOG function, defined in that file, scattered throughout the Zope code. And, your_instance/etc/zope.conf enables you to control the logging output.

Actually this is a bit dangerous if you dont lock

zLOG.LOG(PythonScript, zLOG.INFO, message)
as external method should be enough.

Re: [Zope] Write log file from script
We are running on a linux host. The file information ends upon
in the local file system in the /tmp directory.
