Redirecting Ply error messages

[Steve Garland]

I am using Ply to parse information supplied to an HTML form. Is there some way
to have Ply append error messages to a list from which they can be retrieved by
the Python script I use to process the form? Since the HTML form and the Python
script will be hosted on a machine that is not under my control, I would prefer
not to use Ply's logging interface to write error messages to a log file.

[David Beazley]

The whole reason for using the logging interface is to make it something that could be completely customized in various ways. To accomplish what you suggest, simply make a class that implements the basic logging interface and stores the messages in a list. You should be able to pass your object into Ply using the debug or errorlog arguments to various functions such as yacc() or parse().

Cheers,
Dave
