Multiple icons in a column when in Book List view

[ownedbycats]

I'm not sure for all of then, but try using 'paper' in $$#formats if it's a list-type column.

I've managed it by splitting my symbols column into symbols - source - formats, and by help from you @obc - thank you so much.

It was your post here https://www.mobileread.com/forums/sh...62&post4316762

Same questions as in post 26: do all of those icons exist in the cc_icons folder? Said another way, do you see those icons if you make a basic rule?

Is there another rule higher up the list for the same column? If so, it must be a "composed" icon rule so it doesn't take priority.

Edit: sorry, didn't see the other answers before I posted.

Minor note, but also note that the custom has_data() isn't needed anymore as has_extra_files() exists now.

thx obc, already implemented.

@chaley: I see an icon if I have only one format or source. But as soon as I have two entries, no icon for format/source appears at all anymore.

It works for me. I did make a change to the add_icon() function to avoid empty icon names, but it works without that change.

Here is the booklist:

The icons are on the author column.

Here is the cc_icons folder:


Here is the icon rule screen:


And here is the template, which is the same as yours except the one change mentioned above and changing the 'uk.png' icon name to 'beautify.png':

program:
	def add_icon(icon, val):
		if ! val then return icon fi;
		if icon == '' then icon = val else icon = icon & ':' & val fi;
		return icon
	fed;

	icon = '';
	if $languages == 'eng' then icon = add_icon(icon, 'beautify.png') fi;
	icon = add_icon(
		icon, 
		switch(
			$$#toread,
			'true', 'toread.png',
			'false', 'false.png',
			''));
	if $$#formats == 'paper' then icon = add_icon(icon, 'paper.png') fi;
	if $$#read == 'true' then icon = add_icon(icon, 'ok.png') fi;
	if $$#source == 'geniallokal' then icon = add_icon(icon, 'geniallokal.png') fi;
	if $$#source == 'wbg' then icon = add_icon(icon, 'wbg.png') fi;
	if $$#readinglist != '' then icon = add_icon(icon, 'reading_list.png') fi;
	if $$#annots != 'NONE' then icon = add_icon(icon, 'annotations.png') fi;
	if list_count($authors, '&') > 1 then icon = add_icon(icon, 'series_authors.png') fi;
	return icon

One possibility: you can't use == for multi-value columns. If #formats or #source is tags-like then you must use 'inlist'. as this:

if 'paper' inlist $#formats then icon = add_icon(icon, 'paper.png') fi;

I've tried to add an icon to a column for has_notes similar to extra_files

if has_extra_files() then icon = add_icon(icon, 'extra_files.png') fi;

but this doen't work. Is it possible to show an icon for has_notes regardless the type of notes (author,tag, series...)?

It is possible but will require a new function/template. Reason: notes are not attached to books, instead to metadata items. The new function must check every metadata item attached to a book to see if it has notes.

Are you sure you want to do this? Check for a note on any item in any column?

Edit: I won't be able to provide an example for a while.

@chaley - it would be a hint to look in Book Details to see which category items have Notes. Would I make use of it? Probably not.

Decorating a category cell that that has notes attached to the applied items with a colour or icon might be useful - more so for single item categories such as Publisher and Series than multi-item categories such as Tags. This is not a request that it be implemented.

This template returns the list of lookup names with items on the book that have notes. If none do, return the empty string. If you want to use it, make it a stored template and call it in the icon template.

I don't know if the performance will be acceptable, especially if lots of items in lots of columns have notes.

python:
def evaluate(book, context):
	db = context.db.new_api
	notes_on_book = db.items_with_notes_in_book(book.id)
	return '' if not notes_on_book else ', '.join(notes_on_book.keys())

The above template can be used for this by checking if the lookup column in question is in the list. Something like this, where the above template is stored as notes_in_book.

program:
  keys = notes_in_book()
  if '^publisher$' inlist keys then icon='whatever.jpg' else icon='' fi;
  icon

Alternatively, and faster, would be to modify the python template to take an argument (a lookup name) and check if it is in the list.

The Ctrl+Shift+N keyboard shortcut will pop the Notes browser, if pressed it shows all the notes for all category items that have a note.

It would be nice to have radio buttons similar to those we now have in Manage Categories:- Show all category item notes and Only show notes for category items applied to the selected books.

I did try putting an icon on the Publisher column if it had a note, but for me it's clutter. I'd rather glance at the relevant item in BD, which I do already for Links, if the Notes icon is present I would press Ctrl+Shift+N to see the note.

Now I've got scared.

As I'm about to replace some composite columns with saved searches to improve performance, I'd rather not want to do that.

Thx chaley
