Whipper example config file: % character in inline comment causes InterpolationSyntaxError

whipper.log.gz
When I try to use whipper to rip a cd I always get a configparser error:

~ >>> whipper cd rip
INFO:whipper.command.cd:using configured read offset 103

    raise InterpolationSyntaxError(
configparser.InterpolationSyntaxError: '%' must be followed by '%' or '(', found: "%' must be represented '%%'"

Steps to reproduce the error:

1. run whipper cd rip

I'm using Manjaro Linux and installed whipper from the "community" repository.
I didn't change the default config file (apart from adjusting the drive offset), so it currently looks like this:

[whipper.cd.rip]
unknown = True
output_directory = ~/Musik
track_template = new/%%A/%%y - %%d/%%t - %%n	; note: the format char '%' must be represented '%%'
disc_template = %(track_template)s

Any ideas what might be the problem?

Hi, could you try to just remove the disc_template line (or replace it with the one in the README, the value you're using is non-standard) from whipper's config file and see if the issue is solved?

Thank you, that was one part of the problem. The other part was, that apparently also the mention of '%' in comments isn't allowed, so I also had to remove the comment behind track template before it worked.

Thanks, fixed the bug about the InterpolationSyntaxError caused by the % character in the inline comment with commit 150f0d5.
