Strictly speaking, a <ul> with no <li>s isn't valid HTML either...
could map instead delay emitting the first <ul> until it determines that
it will have at least one item? Perhaps refactoring that function into
something easier to regression-test would be useful. --[[smcv]]
You are right (just checked 4.01 DTD to confirm). I suspect refactoring
the function would be wise. From my brief look at it to formulate the
above I thought it was a bit icky. I'm not a good judge of what would
be regression-test friendly but I might have a go at reworking it. With
this variety of problem I have a strong inclination to use HOFs like map,
grep. - [[Jon]]
The patch in [[map/discussion|plugins/map/discussion]] has the same
problem, but does suggest a simpler approach to solving it (bail out
early if the map has no items at all). --[[smcv]]
Thanks for pointing out the problem. I guess this patch should solve it.
--[[harishcm]]
Well, I suppose that's certainly a minimal patch for this bug :-)
I'm not the IkiWiki maintainer, but if I was, I'd apply it, so I've put
it in a git branch for Joey's convenience. Joey, Jon: any opinion?
If you want to be credited for this patch under a name other than
"harishcm" (e.g. your real name), let me know and I'll amend the branch.
(Or, make a git branch of your own and replace the reference just below,
if you prefer.) --[[smcv]]
The current arrangement looks fine to me. Thanks. --[[harishcm]]
