Please help with regular expressions when adding books

[gill_d]

I have a number of books with filenames in this style:

austen-jane-1775-1817_mansfield-park.pdf

The 1775-1817 bit is when the author was alive, and I don't care if that gets left out of the metadata entirely. I'm also not concerned with capitalising the author and book title correctly.

Others in this style:

london_jack-the_call_of_the_wild.pdf

Others in this style:

Doyle, Arthur Conan - Adventures of Sherlock Holmes, The.txt

Others in this style:

Grimms Fairy Tales - Adventures of Aladdin.txt

Others in this style:

Lewis, C.S - The Chronicles of Narnia 2 - The Lion, the Witch and the Wardrobe.txt


Firstly, I would be grateful for advice on regular expressions for adding these.

Secondly, am I correct in thinking that there's no regular expression which could import all of these correctly at the same time, and thus I will need to import each file-naming-convention separately?

I can't tell you if there is one regex that will do all your filenames.
I know far too little.
If you want to start adding some anyway then ...

Doyle, Arthur Conan - Adventures of Sherlock Holmes, The.txt


Lewis, C.S - The Chronicles of Narnia 2 - The Lion, the Witch and the Wardrobe.txt

This regex from kiwidude works on both of the above two filenames.

^(?P<author>((?!\s-\s).)+)\s-\s(?:(?:\[\s*)?(?P<series>.+)\s(?P<series_index>[\d\.]+)(?:\s*\])?\s-\s)?(?P<title>[^(]+)(?:\(.*\))?

works with;
Bloggs, Joe - My title
Bloggs, Joe - Some Series 1 - My title.txt
Bloggs, Joe - Some Series 1.5 - My title.txt
Bloggs, Joe - Some Series 1.5 - My title with sub-title hyphen.txt

Grimms Fairy Tales - Adventures of Aladdin.txt

Is this
Series - Title
If so the regex below works when I test it.
(?P<series>[^_]*) - (?P<title>.+)
