Help with regex: surely simple, but I don't know how

domax · 10-27-2015, 01:59 PM

a) I have a great number of ebooks with series in title, but wenn I try to put them in Calibre with this regex:

(?P<author>[^_-]+) -?\s*(?P<series>[^_0-9-]*)(?P<series_index>[0-9]*)\s*-\s*(?P<title>[^_].+) ?

I get some faults. First with double names like Jane Miller-Mitch, then Mitch is put in series. Calibre should search vor ( - ).

b) In Calibre I want to search vor german special vocals (=Umlauten) like ö, ä or ü. Or i want to find words like neü. Sorry, but i Can't manage this. Would you please help me?

Thanks

If "-" is in the author name, then using it for the field separator becomes more difficult.

Is there a particular pattern your book filenames have? Maybe list a few of them.

Sorry, theducks, I'll remember this.

No, it isn't. Most are in the way "Give name Family name - series series no. - title". The problem can be:
given name like Marie-Christine, family name Meier-Muller, series Conan-Saga or in title. I really need a way to declare exactly:
space - space

Sorry, my english learning is thirty years ago.

This is just a guess, but I notice you have a couple of instances of \s* in your regex.

What happens if you change them to \s+ instead? The way you have it now, it will match to 0 or more whitespace characters, but I think you want it to match to 1 or more.

hyphenated family names have no space surrounding, so 1 or more will not split there

Current:

Code:

(?P<author>[^_-]+) -?\s*(?P<series>[^_0-9-]*)(?P<series_index>[0-9]*)\s*-\s*(?P<title>[^_].+) ?

New:

Code:

(?P<author>[^_]+) - (?P<series>[^_0-9-]+) (?P<series_index>[0-9]+) - (?P<title>[^_].+)

This *should* accept anything in the form:
author - series series_number - title

Where author can have a "-" as long as it is the only one without spaces surrounding it.

Series should be optional:

Code:

(?P<author>[^_]+)( - (?P<series>[^_0-9-]+) (?P<series_index>[0-9]+))? - (?P<title>[^_].+)

Thanks you all. Now it's easy to integrate series. I use the code of eschwartz and it works.
