Templates: various questions not worth their own thread

program:	

subjects = $#subjects;
admintags = $#admintags;
existing_colls = $#kobocoll;

	new_colls = strcat(	
		if $#booktype=='Fanfiction' then 'Fanfiction,' fi,
		if '^Cozy Mystery$' inlist subjects then 'Cozy Mysteries,' fi,
		if '^Horses$' inlist subjects then 'Horses,' fi,
		if '(Juvenile|Young Adult)' inlist subjects then 'Juvenile & Young Adults,' fi,
		if '^(Fantasy|Paranormal|Science Fiction)$' inlist subjects && !'Star Trek' inlist subjects then 'Fantasy & Sci-Fi,' fi,
		if '^Star Trek$' inlist subjects then 'Star Trek,' fi,
		if 'Omnibus' in admintags then 'Omnibuses' fi,
	);

Line 12, can be done without the extra inlist?

Yes, it can be done but it is complicated and probably slower. It would be some combination of list_intersection and list_count. It could be done as a python template used as a function, something like

check_inlist_field(field, values required, values_not_allowed)

but I don't see a pressing need here.

You should use "inlist_field '#subjects'" instead of "inlist subjects".

I also suggest you use parentheses on line 12 to avoid any possibility of operator precidence being what you don't want. Example:

if ('^(Fantasy|Paranormal|Science Fiction)$' inlist_field '#subjects') && (!('Star Trek' inlist_field '#subjects')) then 'Fantasy & Sci-Fi,' fi,

I have this to display icons for formats, and an unknown icon if none are present:

program: 

formats = approximate_formats();

   strcat
   (
		if "azw3" inlist formats then 'formats_azw3.png:' fi,
		if "cbz" inlist formats then 'formats_cbz.png:' fi,	
		if "epub" inlist formats then 'formats_epub.png:' fi,
		if "html" inlist formats then 'formats_html.png:' fi,
		if "mobi" inlist formats then 'formats_mobi.png:' fi,
		if "paperbook" inlist formats then 'formats_paperbook.png:' fi,
		if "pdf" inlist formats then 'formats_pdf.png:' fi,	
		if "txt" inlist formats then 'formats_txt.png:' fi,	
		if "(overdrive|paperloan)" inlist formats then 'formats_overdrive.png:' fi,	

		if list_difference(formats, 'azw3, cbz, epub, html, mobi, paperbook, pdf, txt, overdrive, paperloan', ',') then 'formats_unknown.png' fi	
   )

Very repetitive. Except for paperloan, Is there a way to regex this to a single line, and would be any faster?

[BetterRed]

Maybe there's a way to use the png's in the ???\resources\images\mimetypes folder, where the image names are the format file types - e.g. epub.png, pdf.png etc.

Yeah, I copied most icons from there (except paperbook and overdrive).

This isn't as repetitive, but is a bit harder to understand.

program: 
	def add_icon_name(res, fmt):
		return res & 'formats_' & fmt & '.png:'
	fed;

	result = '';
	formats = approximate_formats();
	formats_for_book = list_intersection('azw3, cbz, epub, html, mobi, paperbook, pdf, txt', formats, ',');
	for format in formats_for_book:
		result = add_icon_name(result, format)
	rof;
	if "(overdrive|paperloan)" inlist formats then result = add_icon_name(result, 'overdrive') fi;
	if list_difference(formats, formats_for_book & ',overdrive,paperloan', ',') then
		result = add_icon_name(result, 'unknown')
	fi;
	re(result, ':$', '')

{title_sort:'contains(t=uppercase(re($, '^\W*(\w).*$','\1')), '\d', '0-9', t)'}

In a column, this has the first letter of a title (0-9 are combined). An accented letter (É) displays separate than the standard one (E). Is there a way to merge them?

EDIT: Got it (not sure if transliterate should come before or after uppercase).

{title_sort:'contains(t=uppercase(transliterate(re($, '^\W*(\w).*$','\1'))), '\d', '0-9', t)'}
