Add book regex no longer works

[magphil]

Hi,

I have installed a new pc, and made a fresh calibre install.

I then configured it to use my old regexp to add books :

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

and I clicked "Read metadata only from file name.

But when I try and import a new book, the title is not parsed and "author - serie # - title" ends up beeing the book title :-(

any hint welcome.

Cheers,

Magphil

Make sure "Get metadata only from file name" is checked in the preferences, then test it on the regex test. If it fails, tell us exactly what the title is and we can tell you why the regex isn't working for you.

I found a regexp that works on another thread :

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

It's just weird that the other one, which worked for importing a huge number of books, just stopped working.

It didn't stop working. It will work for the same books it worked on before. It's just not a very flexible expression and it depends on the specific characters to be in the right place in each filename. The regex quoted above is much more tolerant of variations in the filename, such as double spaces around the hyphen instead of exactly a single space, etc.
