how to populate pubdate and page count when adding a book?

[Fynjisx]

Hi all! Adding the title of the book to the caliber, the pubdate field is not filled in, in fact it does not exist. Instead, there is another publisher. I would also like to get information about the number of pages of the book from the file name into my custom column. Is there such a possibility?

If the date of publication is in the format file added (e.g. EPUB, PDF) it will be extracted and put into the Published/pubdate column, otherwise use the Metadata download feature to populate that column.

The Count Pages plugin has a number of options for determining page counts, see Index of plugins

Both of BR's suggestions are run POST import as the fill in the blanks (that do not exist until created by the import)

Pubdate is a standard DC metadata (note:Calibre has a column for that. The book creator was SLOPPY if it is missing)

Pages, words, ... all use custom columns and can't be imported unless the person supplying the book has the exact same custom column USAGE.
FWIW If Calibre imports a book THAT populates {series} properly, Calibre was used someplace in its creation.

When you add a book to calibre, it can get metadata from two places. One is the internal metadata for the formats that support it. The other is by parsing the file name. Your image suggests you want to get the metadata from the filename. In that case, you need to write a regex to parse you filenames. But, the only metadata supported when doing this are those listed. These are the standard metadata items that calibre has built into it. This does not include the page count.

To add page count, I would normally recommend the Page Count plugin. That can calculate it from the book or download it from some site. An alternative is to use the GetFileName plugin to put the filename in a custom column and then parse that to put the page count in another column.

please write me a regular expression by which I would parse the string and be sure to test it in caliber:
Ajzek A.B. - Title - (Morgan_Kaufmann_Publisher, 1980).djvu

How can I parse a string using getfilename to get the information I need? Installed the plugin. It displays the file name. Now you have to parse. How to submit it?

For that you will need to use the bulk metadata editor and the "Search and replace" tab. You can use regex to split the filename string and put it into the column of your choice. There are plenty of discussion on using the "Search and replace" in the forum to have a look at. And I think there were some examples in the GetFileName thread.

You could also look at the Action Chains plugin. There is probably a way to do this using that plugin.

teach to use. where should these regular expressions be entered? can you show with an example?

If this can be done, it would be done using the Action Chains plugin.
