Fixed error when ripping using `--keep-going` without specifying `--output-directory`
Added `os.path.basename()` to `skipped_tracks` comparison in
`ImageVerifyTask`. When `OUTPUT_DIRECTORY` is at its default '.'
`./` is prepended to the file path of `index.path`, causing the error.
Merge pull request #536 from whipper-team/misc-changes-template
This pull request extends the supported template variables. Additions:
- `%B`: release barcode (already included but is now allowed)
- `%C`: release catalog number (already included but is now allowed)
- `%c`: release disambiguation comment
- `%D`: disc title without disambiguation
- `%I`: MusicBrainz Disc ID
- `%M`: total number of discs in the chosen release
- `%N`: number of current disc
- `%T`: medium title
When the relative metadata is available, whipper now adds the `TRACKTOTAL`, `DISCTOTAL` and `DISCNUMBER` metadata tags to the audio tracks.
I've also taken the inspiration from pull request #476.
