Numbers in the series name recognized as chapter number if no chapter number in comicinfo.xml

[CtrlAltDefeat94]

What happened?

When the series name in the title contains a number such as Fairy Tail: 100 Years Quest Vol. 1: New Start, New Quest, this number is parsed as a chapter number. All volumes in this series are added for both their Volume number and Chapter 100.

What did you expect?

If a cbz file has a comicinfo.xml and does not contain a Chapter tag, it should not add a chapter number.

Is there anything I can help with to get this out of the triage stage?
I'm currently unable to get (and keep) the Re Zero manga's in Kavita, as it gets confused by the Chapter in the series title.

I need community help with this because partial ComicInfo is a feature many people need. You shouldn't have to tag everything perfectly to correct one issue.

The problem comes from the filename parser, but it's not something that can be fixed per-se. My idea would be to use a unique symbol that would never be real that Kavita can read and ignore said field.

[majora2007]

@CtrlAltDefeat94 can you try for now as a temp workaround to tag the Number field as -100000 and see if that works for you? It's not ideal, but it is the internal encoding that Kavita uses when there is no chapter number.

I'm all in for a special value in comicinfo. So far Ive been tagging these as chapter 0 as a legacy measure.
I'm not sure about parser logic but shouldn't it discard a number if found before volume and/or chapter markers in the filename? AFAIK it should work for Manga naming standards

[majora2007]

Here is the situation with filename parsing:
ABC Chapter 4 - A title.cbz
and
"DEF Chapter 4 - A title.cbz

These are both real titles. The first is the Re:ZERO Chapter 4 case, where Chapter 4 is part of the series name. Whereas Bleach Chapter 4 - Death Gods also is a valid case, where Bleach is the series name.

From a filename parsing standpoint, there is no way to know the difference so there is no way to write a rule to accurately identify. The latter is the most common.

So Using a unique key, like kavita or ignore might be needed. Especially since the standard is pretty frozen.
