I think this does what you want. To make a valid hierarchical item, in authors it replaces periods and commas, and in series it replaces periods. If you have commas in series names then you must replace those as well.

program:
	def first_letter(x):
		return strcat('[', substr(x, 0, 1), ']')
	fed;

# Replace periods with unicode "One Dot Leader" (․)
	period = '․';
# Replace commas with unicode "Small Comma" (﹐)
	comma = '﹐';

	if $series then
		series = strcat('.', first_letter($series), '.', re($series, '\.', period))
	else
		series = '.Standalone'
	fi;

	sep = '';
	result = '';
	for aut in 'authors':
		result = strcat(result, sep, first_letter(aut), '.', re(re(aut, '\.', period), ',', comma), series);
		sep = ','
	rof;
	result

program:
cost = $$#purchasecost;

	switch_if(
		cost == 'none', '',
		'[Bundle]' inlist $#admintags, '[Bundle]',
		'kobopoints:' inlist $#admintags, '[Kobo VIP]',
		cost ==# '00.00', '$0.00',
		cost <=# '00.99', '$0.01 - $0.99',
		cost <=# '04.99', '$1.00 - $4.99',
		cost <=# '10.00', '$5.00 - $9.99',
		cost <=# '15.00', '$10.00 - $14.99',
		cost <=# '15.00', '$10.00 - $14.99',
		cost <=# '20.00', '$15.00 - $19.99',
		cost <=# '30.00', '$20.00 - $29.99',
		'$30.00 and up' 
	)

This returns [Bundle] for nearly everything, even when the entry doesn't exist in admintags. It doesn't happen when I remove square brackets in the test. What happened?

The left-hand side of inlist (the search string) is a regular expression. Square brackets are regexp character classes. You need to escape them if you want them to be normal characters. Use

		'^\[Bundle\]$' inlist_field '#admintags', '[Bundle]',

The anchors ensure that the value matches the entire list item, not a substring.

Note that you can also use the str_in_list() function that doesn't use regular expressions and returns 'found_val' only if the value matches an entire list item.

Thanks. I think I ran into something similar once before

Question: Can this be used in a plugboard? I would like to remove the series name on device if I have only 1 book.

program:

switch_if(
	series_multibook(), $series,
	''
	)

It should work.

In another post, I asked about setting specific time. Now I'd like to know if possble to:

1. Take current date.
2. Subtract one day (April 23 -> April 22).
3. Set the time to 23:59 of that date.

This would be for Reading Goal setting the #lastread - I update my daily page at end of day, but sometimes forget till next morning which messes up the page-per-day count.

program:
	date_arithmetic(re(today(), 'T.*\+', 'T00:00:00+'), '-1m')

This gets the current date and time, sets the time to midnight, then subtracts one minute from that to get 23:59 on the previous day.

I'm not sure why, but can't get it working. Returns current datetime minus 1 minute.

Works fine for me. The time is set to 23:59. The date might not be yesterday because of timezones.

Please attach both what today() and the re() return so I can check the regular expression. Both must be in ISO format.

[chaley]

Try this:

program:
	date_arithmetic(re(today(), 'T.*([+-])', 'T00:00:00\1'), '-1m')

re(): 2025-04-23T19:51:10.719873-03:00
today(): 2025-04-23T19:50:10.719873-03:00

The new code works.

[ownedbycats]

program:

bookformat =
	switch_if(
		'PAPERBOOK' inlist_field 'formats', 'Physical Books',
		('OVERDRIVE' || 'PAPERLOAN') inlist_field 'formats', 'Loans',
		'eBooks');

Test book with only a PAPERLOAN format, returns eBooks. What I do wrong?

EDIT: ('OVERDRIVE' inlist_field 'formats' || 'PAPERLOAN' inlist_field 'formats') works, was hoping to avoid repeated.

inlist and inlist_field have a regular expression on the left hand side. You put a boolean expression. What you want is a regular expression using alternatives.

This should work:

program:

bookformat =
	switch_if(
		'PAPERBOOK' inlist_field 'formats', 'Physical Books',
		'OVERDRIVE|PAPERLOAN' inlist_field 'formats', 'Loans',
		'eBooks');
