Help needed: Regex for Add Books

macnab69 · 03-23-2015, 03:49 AM

This is my current regex:

Code:

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

for format

Code:

author - [series series-index] title

I need it changed to handle

Code:

author - [series series-index] !tag1, tag2# title

Do you want to capture everything between a "!" and a "#" as the contents for the tags column?

If so, try:

Code:

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

(My addition is in red.)

Doesn't read the tags. Everything else still works.

calibre doesn't read into Tags column from filename.

EDIT: Setting "Read metadata from file rather than filename" does it.

eschwartz · 03-24-2015, 12:16 PM

That would imply the tags and other info are already embedded in the file.

Also, sorry for not realizing Add books doesn't allow tags as a filename metadata source.

@macnab69 - the cli command calbredb -add can contain tags.

With a text editor perhaps you could munge the file names into calibredb add commands.

@eschwartz: In my case the books have been through calibre to edit them, because so many have terrible layouts and formatting.

@Better Red: Some sort of script would be needed to parse each filename. At least calibredb add allows to to set Tags.

eschwartz · 03-24-2015, 10:56 PM

If they have been through calibre, why do you need to add metadata based on the filename?

BetterRed · 03-24-2015, 11:06 PM

@macnab - I would pipe a directory list of the 'files with tags in file names' into a command file -- bat, bash -- whatever.

I'd then open that file in an editor like Notepad++ or emacs, do find & replaces to transform each line into a calibredb add command with the --tags "blah, blah blah, blah blah blag" etc.

Run the command file, throw it away

@eschwartz - I fix the books for a friend who is not really savvy. It wasn't until now that I thought about the metadata being embedded in the file.
