Counting Tags

[sarahmelissa]

So I've spent the last couple of months chipping away at the tag metadata of all my ebooks. I've gotten it down from 5000 to about 350. I did a significant portion of it in the bulk tag manager, which has resulted in the problem of many of the books having too many tags (upwards of 10).

Can anyone explain to me how to create my own column that contains the tag count for each book? I've been trying to decipher the Calibre user manual for a few hours and my eyes are starting to glaze over...

I'd really appreciate a bit of help! Thanks so much

Please read this (search for "count(separator)").
I think what you need is

{tags:count(,)}

Edit: I usually use Quick Search (the text box on the left column of the manual) to find what I need if I don't remember exactly where it is in the manual. In this case, I typed "count" and clicked the second link. Using more words, Quick Search for "count custom column" will give you the right link as the first result.

Create a column with type "column built from other columns". You probably want to set the "Search/Sort column by" box to "Number" so that you can use numeric sorting, and also searching such as #yourcolkey:>10.

Set the template to

{tags:count(,)}

For completeness, the above is a single-function mode template. The same template in template-program mode is

{tags:'count($, ',')'}

The same template in general program mode (runs faster than either of the above) is

program: count(field('tags'), ',')

The Quality check plugin has a excessive Tag count (number configurable) check. Once the (count exceeded) results display, you can choose where to go from there

Thank you all so much for your responses. I'm so grateful, I could hug you!
