Can't change TransLogger format

[ariksa]

You are right, I saw that dictionary and hence opened this issue.
But I can't fight maintenance mode :)
Thanks, closing.

Can you provide the MY_FORMAT that you are using that fails, and the traceback that happens when it fails? Without that it's hard to narrow down the issue.

I wanted to go with a standard logging format:
MY_FORMAT = '[%(levelname)s] (%(filename)s:%(lineno)d) - %(message)s'

Traceback (most recent call last):

Ah, okay. As you've probably already determined, there is a defined set of variables that you can provide, using Translogger, the left hand side in this dict:

        d = {                                                                   
            'REMOTE_ADDR': remote_addr,                                         
            'REMOTE_USER': environ.get('REMOTE_USER') or '-',                   
            'REQUEST_METHOD': method,                                           
            'REQUEST_URI': req_uri,                                             
            'HTTP_VERSION': environ.get('SERVER_PROTOCOL'),                     
            'time': time.strftime('%d/%b/%Y:%H:%M:%S ', start) + offset,        
            'status': status.split(None, 1)[0],                                 
            'bytes': bytes,                                                     
            'HTTP_REFERER': environ.get('HTTP_REFERER', '-'),                   
            'HTTP_USER_AGENT': environ.get('HTTP_USER_AGENT', '-'),             
            }                                        

To get the output that you want you're probably better off using either a different logging middleware, or a subclass of Translogger.

In any case, given that paste is in maintenance mode, and the code is behaving as designed (setting aside for the moment whether that design is good), this is not something that's going to change.

I'm not certain, but I suspect either waitress or flask should be able to provide you with different modes of logging that could fit your needs.

If all that makes sense, please close the issue.
