Group news items from the same source

maximus83 · 01-19-2019, 01:43 PM

In Calibre News view, how can you customize the view to visually group multiple news items from the same source?

For example, say you download daily from the the New York Times. You end up with multiple dated New York Times items in your News view; it gets cluttered over time. It would be handy to be able to create a custom view that groups all news items from the same source.

ETA: Here's a screenshot showing the problem of multiple dated entries from the same source. Calibre builds each daily download from a given source into an Epub and treats it like a separate book.

Isn't the source, the Publisher?

Yes? But I still want to create a view that groups multiple dated entries from same source. Also I wouldn't see it as necessarily reliable trying to group by "Publisher" field, as a lot of the news entries end up showing calibre as the Publisher.

Do a multisort, by title and date.

You can get close to what you want, a grouped display to the tag browser, by creating a "Column built from other columns" (not tags) with "Show in tag browser" checked, adding that column to the list of hierarchical tags (Preferences / Look and feel / Tag browser / Categories with hierarchical items), then using an appropriate template in the column.

I don't have any sample news data so I can't provide a template that is tested, but this one should come close.

Code:

program: re_group(field('title'), '(\.)| *\[(.*)\]', ":", "{$:|.[|]}", ',')

This converts any periods in the title to colons so they don't interfere with grouping, then adds a grouping period in front of the square-bracket-enclosed date.

After you make the above work, you will see the news articles in the tag browser with the name as the outermost item and the articles by date as the subitem.

Thanks guys, good tips.

The custom column + regex sounds cool. Will give that a try this week and circle back here with an update.
