And just as many assume it has something to do with the file system Modified date

IIRC POSIX uses Change date for metadata changes, and Modified date for content changes.

I learnt early on to ignore calibre's Modified/last_modified column.

I think he means it opens the edit metadata window?

Your presumption is incorrect. I use it to open edit metadata. I seldom edit data in the booklist.

I'm sort of surprised one can even nominate Return and Numpad/Enter as shortcut keys, but I see one can - that's pretty cool. Now I'm trying to think of how I could use it.

FWIW: I used the tweak "Control behavior of the book list (ID: doubleclick_on_library_view)" to make Return do an edit metadata.

I did a test and using Return as a keyboard shortcut overrides the tweak.

Question. I have this composite column, with sort/search by text:

program:

input = $#kobobookmark;
a = re(input, '.*\/file(\d+).*', '\1');
fan = $#fanficcat;
status = $#fanficstatus;
ccount = $$#chaptercount;

	if 
			fan
		&&
			status !='Anthology'
		&& 
			$#currentlyreading 
		&& 
			substr(input, 0, 10) == 'OEBPS/file'
	then		
		strcat(format_number(subtract(a, 1), '{0:,d}'), '/',ccount)

	elif
		status ='Oneshot'
	then
		ccount

	elif
		ccount >#1
	then
  		ccount

	fi

On a non-fanfiction book with an undefined ccount this displays as "None." If I switch to non-raw field it becomes blank instead.



I don't mind it here, but why does raw field result in "none" instead of blank?

Actually I just realized I could probably remove the second elif statement and combine it with the third with a != compare op...

[ownedbycats]

Hmm, the compare op didn't seem to work. I tried this:

	elif
			ccount >#1
		&&
			status != 'Oneshot'
	then
  		ccount

It resulted in a null on a oneshot (by definition, those are always one chapter )

$$#x is equivalent to raw_field('#x'), which returns 'None' if the value is undefined. If you don't want that then use raw_field('#x', default) where default is whatever you want to see if the value isn't defined. In your case I think you want default to be ''.

EDIT: BTW: raw_field() is useful where the field is formatted in its column definition with characters so that the displayed value is no longer a number. The raw_field() function returns the underlying number, not the formatted one.

[ownedbycats]

My percent read column has some formatting to show a percent sign. I found if I don't use raw field when putting it into a composite I get unexpected results.

Ok I figured it out. It wasn't the compare op, but there's no other statements telling it what it should display if it's a oneshot. I'll just leave in the second elif statement, it's easier.

if 
		variable !='foo' 
	&&
		variable !='bar'
then	
	'output'

Is there a way to merge the two checks?

[ownedbycats]

Also:

program:

input = $#kobobookmark;
a = re(input, '.*\/file(\d+).*', '\1');
status = $#fanficstatus;
ccount = $$#chaptercount;

	if 
		$#fanficcat
	then
		if		
				!status inlist 'Anthology,Oneshot'
			&& 	
				substr(input, 0, 10) == 'OEBPS/file'
			&& 
				$#currentlyreading 
		then		
			strcat(format_number(subtract(a, 1), '{0:,d}'), '/',ccount)
		else
			ccount
		fi

	elif
		ccount >#1
	then
  		ccount
	fi

I might've asked this before, but does it do all the checks, or only continue the check when it passes the other ones?

If the latter, since #currentlyreading is another composite (psuedobool, it returns 'true' if it passes certain checks), would putting it last be better practice for performance?

Also, are there any other improvements that can be made to this? I notice there's a slight delay whenever the column updates. I've thought of taking out the #currentlyreading check and instead just having it run its checks directly, but I'm not sure if that would help or if there's a better way.

description of template:

Spoiler:

What I'm doing here is:

Check whether or not it's a fanfiction (#fanficcat defined).

If it is, check for three things:

a) Status is not 'Anthology' or 'Oneshot.'
b) #kobobookmark starts with 'OEBPS/file'
c) #currentlyreading is defined

If all three of these are true, do that number formatting stuff; this shows how many chapters I've read compared to how many there are (e.g. 23/25).

If it's a fanfiction but does not fulfill all three checks, display the chapter count.

If it's not a fanfiction, display the chapter count only if it's above 1.

program:
	! variable inlist 'foo,bar'

Will that work for an enumerated column?

I guess yes. No reason for it not to work with enums.
