looking for the correct regex

[oloco]

Hi,
During the last years, I've been storing all my books using this simple format:

El tutorial de python - Guido van rossum (2017).pdf
Zed A. Shaw - Learn Python The Hard Way (2011).epub

I'm lookinf for a regex template to be able to capture the metadata correctly.

I've tried multiple kind of combinations, but I'm not being able to capture the year.

One of the last examples I tried:

(?P<author>[^_-]+) - (?P<title>[^_].+) (?P<published>[^_]).+?

No matter the way I trie.. i never get the year.

Could yopu please help me with this?

Thanks in advance!

You forgot the parentheses:

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

Hi Divingduck,

thanks a lot for your answer. I've just tried the example you propposed, but it doesn't seem to work. The problem is that the year is not being detected.

Do you have any other seugestion for me?

Thanks a lot!!

Hm,
See attached pictures. Looks good for me.
I attached two dummy files w/o content that I used as test. In the first two pictures I made a test with the import test dialog. You may recognize that you provide two different examples, one with [author - title (year).ext] and the other with [title - author (year).ext]. In this case you need two separate templates for matching the metadata sequence and then switch to the one needed for importing.

For my example I use [author - title (year).ext] with:

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

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

Variations for [author - title (year).ext]:

(?P<author>[^_-]+) - (?P<title>[^_].+) \((?P<published>[0-9]{4})\)

or

(?P<author>[^_-]+) - (?P<title>[^_].+) \((?P<published>\d{4})\)

Picture 3 shows the imported files with the correct author, Title and publish year. Be aware you need to uncheck the box for [Read metadata from file contents rather than file name] for reading the meta data from file name, see picture 4

Template for [title - author (year).ext] should be:

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

Hey! You can try this regex to capture the year:
(?P<title>.+?) - (?P<author>[^-]+?) \((?P<year>\d{4})\)\.

Hi @Divingduck and Yves54.

I'be just tested " (?P<title>[^_-]+) - (?P<author>[^_].+) \((?P<published>.+)\) " and seems to work fine for me.

Thanks a lot for your help!!!
