However, I still need a way to prevent configobj from stopping when it finds a duplicate key word entry. The link you posted says that the default for raise_errors is False and that parsing should continue. However for my program it stops parsing and the program exits. I did find that i can define the following in my program and it works for me: >>> >>> >>> >>> >> Although ConfigObj continues parsing it still raises an exception when >> it finishes parsing. >> >> Therefore instead of your code you could use: >> >> try: >> >> config = ConfigObj(filename) >> except ConfigObjError, e: >> config = e.config >> >> This ignores the error and uses whatever ConfigObj managed to find. >> >> Michael >> >> >> >>> def _handle_error(self, text, ErrorClass, infile, cur_index): >>> ##the next two lines i added to stop duplicate >>> ##entries from causing problems >>> if ErrorClass ==configobj.DuplicateError: >>> return >>> ##this is the end of the changes i made. >>> line = infile[cur_index] >>> cur_index += 1 >>> message = text % cur_index >>> error = ErrorClass(message, cur_index, line) >>> if self.raise_errors: >>> # raise the error - parsing stops here >>> raise error >>> # store the error >>> # reraise when parsing has finished >>> self._errors.append(error) >>> configobj.ConfigObj._handle_error=_handle_error >>> >>> This works but im not sure that this is "good coding" practice. >>> The following is the problem im am having. >>> >>> >>> >>>>>> x=configobj.ConfigObj("conf") >>>>>> >>>>>> >>>>>> >>> Traceback (most recent call last): >>> File "<stdin>", line 1, in <module> >>> File "/var/lib/python-support/python2.5/configobj.py", line 1272, in __init__ >>> self._load(infile, configspec) >>> File "/var/lib/python-support/python2.5/configobj.py", line 1355, in _load >>> raise error >>> configobj.DuplicateError: Duplicate keyword name at line 3. >>> >>> the conf file looks like this: >>> [conf] >>> value1= workgroup >>> value1=workgroup2 >>> >>> Any pointers would be appreciated. >>> Thanks, >>> David >>> >>> >>> >>> Michael Foord wrote: >>> >>> >>> >>>> David B. wrote: >>>> >>>> >>>> >>>> >>>>> Im trying to use the exceptionlist that is mentioned in the docs on the >>>>> website to stop my program from erroring out if there is a duplicate >>>>> value entered in the config file.
