Books' props are not cached. Can be added if we feel that requesting CoverBrowser database is not fast enough for folders with many files.

Not familiar with sorting, and it's all a lot of refactoring, so trusting you :)

(We may have complain by users saying authors and keywords are lists - so sorting/filtering is a bit tedious. May be the title should say "by first keyword", "by first author" - but this is a bit ugly.)

Yes, mostly refactoring based on our flexible collate system.

To get document props, collate item_func needs FM/Reader instance passed through FileChooser.
Similar to Collections I named it _manager, but now I see that it's our usual ui, so renaming.

file_chooser is now init-ed after all plugins, i.e. after CoverBrowser's patching done.

Usually the author's name is in the form "first name-surname". If we sort the files by "Authors", I think it would make more sense to sort by surname. So I think the last name in the author's name order should be used for classification.

Author field is not separated, just a string "John Smith".
Sometimes "Smith, John", sometimes "John W. Smith".
How can we get the surname? In other languages?

I see that this is done in the Pocketbook library when books are sorted by author's name and I assumed that there was a way to set the "last word" in the Author field as a sorting factor. If that's not possible, no problem.

A user on reddit says Search is missing in FM.

Haven't tested myself yet, can help later

Thanks, shall fix today.

@ichnilatis-gr if you want to test sorting by author's last name, here is the userpatch:

2-sort-by-author-last-name.lua.txt

@ichnilatis-gr if you want to test sorting by author's last name, here is the userpatch:

Thank you! It's not bad. It even struck me that sometimes, even though the surname is first (surname; first name), it is sometimes correctly classified according to the surname... Will it be merged?
The other option is to put surname first in the file name and sort files by name, which is what I usually do...
... or to have two choices for sorting by name, one by first name and one by surname... :-)

Maybe. If you meet an author that produces incorrect surname, please send this string to me.

@ichnilatis-gr if you want to test sorting by author's last name, here is the userpatch:

2-sort-by-author-last-name.lua.txt

Is this a different file? I see that it has a different name from the booklist.lua you gave me a few days ago. Has something changed? I can save it in the same folder?
Thanks!

booklist.lua is a program module, it will be overwritten by updates.
2-sort-by-author-last-name.lua is a userpatch.

2-sort-by-author-last-name.lua is a userpatch.

Which means what? :-)

So, Can I make a folder koreader\patches and it put the file there? In this case does it function despite the booklist.lua?

Dear @hius07, did I understand correctly about the patches? I am sorry for my ignorance and constant annoyance.

Yep.

Yep.

I was thinking of deleting my perhaps silly questions today after seeing the patches work in practice, but you beat me to it. :-)
Thanks!
