[GUI Plugin] Library Codes

[kcar181]

Thanks my friend. Great plugin by the way

[DaltonST]

If you run Calibre in DEBUG mode, it will show you exactly what codes it got from where.

FAST codes are gotten along with DDC and LCC from the official OCLC Classify API.

LCEAD codes are "keywords" gotten from WorldCat via LC-specific webscraping.

There does appear to be an overlap (they pertain to the same book after all), with some books having more common tags and others having fewer. However, they are usually not identical, especially for Non-Fiction.

Way too many books run at one time. Do a single debug Calibre session debug log for one (1) book. The point is to compare FAST Tags to LCEAD Tags. Just want to look at the FAST Tags added for the same book for which LCEAD Tags are being added simultaneously. There should be a single debug log.

Added: I am working on a new menu selection to automatically remove redundant LCEAD Tags in favor of FAST Tags. This will be useful regardless of anything else going on.

Hello! Based on your _lc_genre_mapping_csv.txt and my own list of DDC headings, you I've written a template function to calculate nested DDC headings from DDC codes (see attached screenshot). The difference is that instead of including each sublevel in the list, the function calculates the nested levels from the superior decimal codes. You can find the template function attached, I hope you find it useful!



Of course, to view it you must add a custom column with that template function:



ddc_head.py

Oops

that should be a bit clearer. And isra00 that looks interesting

[DaltonST]

Looks correct to me. LCEAD values have some unique tags, some tags identical to FAST tags, and some similar but not identical.

All things being equal, Fiction and non-Fiction have different expected results for FAST and LCEAD usage. LCEAD seems to be more useful for non-Fiction. In both cases, you just get what you get. Mass deletion for Fiction is always an option.

The new LC menu option I mentioned in a post above will take care of the identical overlapping tags.

I should upload the new version by Friday.

Ok thanks for looking at it keep up the good work

Version 1.0.46 - 2020-07-22 New menu option to remove redundant LCEAD Tags that already exist as FAST Tags for the same selected books.

Note that LCEAD Tags for Fiction are often the same or similar to FAST Tags, whereas for Non-Fiction they are much more useful.

All GUI plugins use the identical Favourites-plugin compatibility code originally written by kiwidude when he wrote the Favourites plugin years ago.

Several months later, I still haven't gotten the Library Codes menu entries to work correctly with the Favourites menu.

Here's my steps to replicate:

1. Completely uninstall Library Codes by deleting both the plugin and the json config.
2. Reinstall it from the plugin manager. (Calibre 5.5 now.) Configure it again.
3. Open the Favourites menu config. Add "Convert ISBN-10 to ISBN-13" to the menu.

Expected result: That it appears in the menu and works properly.
Actual result: It appears as an iconless "Library Codes." Clicking on it does nothing, even when I ensure there's at least one book with an ISBN-10 identifier.



Any ideas what I may have broken here? I have a few Job Spy entries in the Favourites menu and they work correctly. As well, the Library Codes menu works when added as a whole, but I'd like to avoid accidentally clicking "Scrub ISBNs" when I'm trying to convert them.

[DaltonST]

This has nothing to do with, nor is impacted by, the removal and reinstallation of LC and its .json file.

I reproduced your results, and the Favourites plugin apparently cannot handle your scenario, losing the icon that clearly exists.

Adding the entire LC menu works, of course. Not just a single menu item for LC when the entire LC is also added to Favourites.

Added:
You have added both LC itself, plus a single menu item to Favourites. In my opinion, that is the root cause of your issue. It causes a collision of Favourites unique names. Either do one, or the other, not both, and see if your issue disappears.

I removed LC from the Favourites menu. Adding the Convert ISBN item still doesn't work.

[DaltonST]

Restart Calibre to restart Favourites.

[ownedbycats]

Restarting also didn't work.

Also, opening the Favourites config menu again shows that it now fails to recognize the item I added.
