Templates: various questions not worth their own thread

[JohnnyBook]

When viewing Calibre's main screen of the list of books in my library, if I have an book selected, when pressing the TAB button the highlighted field will advance to the next field.
i.e. Title -TAB- Series -TAB- Tags -TAB- Publisher, etc. until it reaches the end and the next book is selected.

Good.

But recently I noticed if I am Editing a field, when I press TAB instead of moving to the next field, it backs up to the previous field.

For example:
I am editing the title: "Lord of the Rings: The Two Towers: A Magical Fantasy Adventure"
My preference is to have "Magical Fantasy Adventure" as Tags and "Lord of the Rings" as the series

So I will edit the title and cut ": A Magical Fantasy Adventure" and TAB to the Tags Field and paste it there (editing it and adding commas) "Magical, Fantasy, Adventure"
Then TAB back to the Title and cut "Lord of the Rings: " and TAB to the series field and past it there (with edits) "Lord of the Rings" and add series number if needed.
Leaving "The Two Towers" as the title.

The problem is lately I noticed that when I am editing the title and I TAB the selected field does not advance to the right, it moves to the left, pressing Shift-TAB does move to the right. (TAB and Shift-TAB are reversed)

Also it is not consistent, if I am editing Series, and TAB it jumps 2 fields to the right to Publisher.

Maybe fields have an order now?
So that TAB advance by the field order instead of what is shown visually on the book list

I tried doing a search and looking through the tweaks but cant spot anything to adjust to restore how the TAB when editing fields reacts.

Any thoughts?

EDIT: When reviewing the forum I spotted someone else posting the same problem.
It's a BUG - - It's a known V7.26 bug ==>> V7.26 Editing in the Book List

You can do as I've done, revert to 7.25 pending 7.27 release, or install the latest preview release.

I am having a problem with my composite column. I want to create a column that counts the number of tags I have displayed

The template is:

list_count_field('tags')

Any help would be appreciated

Thank you so much. That worked like a charm.

I've got a doubt. I'm not very good with regular expressions, so I'm using this template for checking if there are non-ascii characters in a title:

program:
	title=field('title');
	aux=transliterate(title);
	if (title!=aux)
	then
		'true'
	else
		'false'
	fi

The template is returning true if there is a 'é' in the title, so it's fine. However, I'm using it as advanced rule for adding an icon to a column and the icon is not appearing. Is there is any issue with the template, the advanced rule, my way of doing it? I'm using calibre 7.23 (all the following versions have a mistake that affects my way of working) and windows 10 64 bits.

In an advanced icon rule the template must return the base name of the icon you want, for example 'myicon.png'. That icon must be in the cc_icons folder. Return the empty string if you don't want an icon.

Thank you! Yes, I remember now that is the same with colouring columns.

Can template convert seconds to minutes/hours?

Yes.

program:
# Example: 3 hours, 12 minutes, 33 seconds
	input_secs = (3 * 3600) + (12 * 60) + 33;

	hours = floor(input_secs/3600);
	minutes = floor(mod(input_secs, 3600)/60);
	seconds = mod(input_secs, 60);
	r = hours & ' hours, ' & minutes  & ' minutes, ' & seconds & ' seconds'

OK, so apparently in version 8.x "{author_sort:.2}" is no longer recognized. The equivalent to the old "{author_sort:.1}" is apparently "{author_sort[0]}", but what can I use for the first TWO characters of a field?

{author_sort:.2} works fine for me with calibre 8.1.1 on Windows 11.


What OS are you running? If Linux, are you running the official calibre binary or some distro-provided version?

hi, need some help.

i want to a second author category in the tag browser that goes fist letter Author > Author > fist letter Series > Series, so i got this:

program:

    if $authors != ""
    then
        first_letter = substr($authors, 0, 1);
	first_s_letter = first_non_empty(substr($series, 0, 1), "");
        if $series != ""
        then
            '[' & first_letter & ']' & '.' & $authors & '.' & '[' & first_s_letter & ']' & '.' & $series
        else
            '[' & first_letter & ']' & '.' & $authors & '[' & '.Standalone' & ']'
        fi
    else
        "Unknown Author"
    fi

what im having problems with is that in the authors column i divide the authors with '&' not ',' so it ends up looking like the image

What do you want it to look like? What is supposed to happen with multiple authors? Is the column supposed to be hierarchical? And why are you surrounding the first letters with "[" "]"
