calibre regexp for adding books

garberw · 08-29-2015, 12:27 AM

adding books to calibre, trying to get regexp for recognizing metadata
for books in this format:

\[(?P<title>[^\]]+)\](?P<author>[^(]+)\(ZAP\.org\)\.pdf

[Betty Crocker]Cooking is Fun(ZAP.org).pdf

that regexp doesn't work.
I think it's something about the first [^\]]
If there is a bug, how do we contact the calibre author?

Try

Code:

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

or even

Code:

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

That doesn't work because the first part of the regexp matches the whole string.

I hate to say but I tested those out in the test interface and they worked like a charm.

\[(?P<author>.+)\](?P<title>.+)\(ZAP\.org\)\.pdf
does not work but
\[(?P<author>.+)\](?P<title>.+)\(
does work.
I do not understand.
Both should match
[cooking]mytitle(ZAP.org).pdf
The second one does work I just tested it.
Also, why doesn't the first ".+" just match the whole expression following it
until the end of the line?

\[(?P<author>.+)\](?P<title>.+)\(ZAP\.org\)\.
fails

\[(?P<author>.+)\](?P<title>.+)\(ZAP\.org\)
passes

with filename
[cooking]mytitle(ZAP.org).pdf

it fails on the second period for some reason.

the \.PDF is wrong
you do not include the extension part of a file name

OTOH Name\(pdf\) would be included If you wanted that as part of the Title

garberw · 08-29-2015, 02:50 PM

still, this does the job, and it has the added bonus
that it can match either .pdf .djvu or .epub formats

Calibre (default setting) will only add known book (related) types
by default
.MP3 would not be added
.(blank) ignored

\[(?P<author>.*?)\](?P<title>.*?)\(ZAP\.org\)

This works and is what I was originally looking for.
You guys explained it.
All the other solutions worked fine when you remove
the ".pdf" from the end of the regexp, since it is matched
automatically.
Also, I did not understand that regexp match the longest
string possible (by greedy default) but
*cat
still matches
acat
the * does not match the whole string, it backtracks.
Could I please request that they put something more in
the documentation about the automatic matching of extensions
such as .pdf (or is this my fault for not RTFM?)
