Author Emblems

DBorG · 09-21-2022, 08:00 AM

I need help.
Among other things, I trying that in cover grid Calibre displays authors pics as emblems, and I like it.
Problem is basic rule is ok for few authors,
but how to implement that to my main library that has 10k+ authors.
I would need 10k+ rules

How to create advanced rule that would show author image if name of image is equal to authors name.

example of basic rule:
program:
test(str_in_list(field('authors'), '&', "Andy Weir", '1', ''), 'andy weir.png', '');

For only the first author:

Code:

program: list_item($authors, 0, '&') & '.png'

this whil return: Arthur C. Clarke.png

Get emblems for all authors [composed icons]:

Code:

program: rslt=''; authors = $authors;
rslt = list_item(authors, 0, '&') & '.png';
for i in range(1, list_count(authors, '&')):
  if i == 6 then break fi;
  rslt = rslt & ':' & list_item(authors, i, '&') & '.png'
rof;
return rslt

this whil return: Arthur C. Clarke.png:Gentry Lee.png
(the colon is for separate the individual icons. You can limite the number of emblems display by changing the number 6)

EDIT: the case does not matter.

It works perfectly, and with little tweaking I can use it for whole lots of other things, like with custom column awards i can show award icon if book has some awards and so much more....
Thank you so much.

What size should the png with the author's name be?

I think default is 128x128, but I use much larger 600x600, I know it is overkill, but, hey.

Thank you again your solution is great,
and I did manage to adjust it for my custom #awards column.
But then i got greedy, instead of two columns,
one for awards and one for award year, which works with your solution.
I tried hierarchical for awards: hierarchy being awards.year
and I don't know how to add wildcards to rule.

edit: two columns solution works for one award,
but if book has more than one award, you have to use hierarchy.

think it could be done with command shorten,t o shorten #awards by 5 letters, but to the likes of me whatever I, try its not working.
