Problem with reg expression !

tonibat · 05-14-2020, 08:57 PM

Have got quite a large collection of books in the format:
"[Author1, Author2...] Title - Subtitle"

It seems that the reg expressions interpreter won't allow this. No way to get it to accept the '[' and ']' as valid delimiters. Any clue to a solution ?

Thanks

Escape them with a preceding backslash

Doesn't work for me.
I have my files in format: [<author>] <title>.ext, for example:
[John Doe] Mybook.pdf

and I've tried several patterns:

\[(?P<author>[^_]+)\]\s(?P<title>.+)

\[<author>\]\s(?P<title>.+)

as well as some smpler ones:

\[<author>\]\s<title>

None of them works. All result in
Title: [John Doe] Mybook
Author: Unknown
So, the author is not parsed, it is all put into the title.

I have Calibre 1.25 in Linux

Really? Calibre 1.25? I would strongly recommend upgrading.

I don't have a version of calibre that old to test with. But, using the test in the Adding books page of the preferences, the first one above works correctly.
