To make this work you need to define the function. Put the following at the top of the template after the program: line.

	def do_field(field_name, icon):
		return (if v = field(field_name) then icon & v fi)
	fed;

Reasons:

• The long list of conditions becomes much easier to read.
• It saves editing if you want to change how an icon clause works.
• The 'if' in the function uses the same technique as above for performance improvement.

I liked this approach and now I have:

program: def do_field(field_name, icon, something, something2):
		return (if v = field(field_name) then icon & v  & something & something2 fi)
	fed;
out = '  💾 ';
fmts = list_sort(formats_sizes(), 0, ',') ;
for fmt_data in fmts:
fmt = sublist(fmt_data, 0, 1, ':');
size = sublist(fmt_data, 1, 2, ':');
str = if size ># 0 then strcat(fmt, ': ', human_readable(size), ' | ') else '' fi;
out=strcat(out, str)
rof;
if substr(out, -2, 0) == '| ' then
out = substr(out, 0, -3)
fi;
out

& strcat(
do_field('#li', '​ ✍️ '),
do_field('#fav', ' ⭐:'),
do_field('#pp', '​ 📈 ', ' pages') ,
do_field('#words', '​ 📈 ', ' words') ,
do_field('#ac', '​ 🟨 '),
do_field('#ot', '​ 🌱 '),
do_field('#tr', '​ 🌐'),
do_field('series', '​ ▶️ ', ' - ' , field('series_index'))
)

It was cool to figure out how to concatenate the pages, words and series info, by adding those extra 'somethings', though I suspect there's a simpler way. I've added #ot (original title) and #tr (translator) as I have populated the db with this info for some titles.
