+## Multiple values arrays
+
+This breaks if there are multiple values for a single key. It works fine in the report plugin, but inline display shows the ARRAY reference, e.g.
+
+ IPv6:
+ - fd64:2c08:9fa7:4::1
+ - 2001:470:1d:4a6::1
+
+and:
+
+ {{$IPv6}}
+
+yields:
+
+ ARRAY(0x266db10)
+
+Seems to me this could be checked and `join(" ")`'d. :) -- [[anarcat]]
+
+> I wrote a stupid fix for this, which works for getfield, but isn't as good for report. It simply does that `join()`. Here's the patch:

## Templating, and other uses
Like you mentioned in [[ftemplate]] IIRC, it'll only work on the same page. If it can be made to work anywhere, or from a specific place in the wiki - configurable, possibly - you'll have something very similar to mediawiki's templates. I can already think of a few uses for this combined with [[template]] ;) . --[[SR|users/simonraven]]

+>> I don't know the internals very well, I think that's how other plugins do it. *goes to check* Usually it's a `foreach` loop, and use a `pagestate{foo}` to check the page's status/state. There's also some stuff like 'pagespec_match_list($params{page}` ... they do slightly different thing depending on need. --[[SR|users/simonraven]]
+
+>>> No, I meant what markup I should use; the actual implementation probably wouldn't be too difficult.
+
+>>> The current markup is {{$*fieldname*}}; what you're wanting, perhaps it should be represented like {{$*pagename*:*fieldname*}}, or {{$*pagename*::*fieldname*}} or something else...
+>>> -- [[KathrynAndersen]]
+
+>>>> Oh. Hmm. I like your idea actually, or alternately, in keeping more with other plugins, doing it like {{pagename/fieldname}}. The meaning of the separator is less clear with /, but avoids potential issues with filename clashes that have a colon in them. It also keeps a certain logic - at least to me. Either way, I think both are good choices. [[SR|users/simonraven]]
+
+>>>>> What about using {{pagename#fieldname}}? The meaning of the hash in URLs sort of fits with what is needed here (reference to a 'named' thing within the page) and it won't conflict with actual hash usages (unless we expect different named parts of pages to define different values for the same field ...)
+>>>>> -- [[Oblomov]]
+>>>>>> That's a good one too. --[[simonraven]]
+>>>>>>> Done! I used {{$*pagename*#*fieldname*}} for the format. -- [[users/KathrynAndersen]]
+
+
> I'm also working on a "report" plugin, which will basically apply a template like [[ftemplate]] does, but to a list of pages given from a pagespec, rather than the current page.

+>> Ooh, sounds nice :) . --[[SR|users/simonraven]]
+
+>>> I've now released the [[plugins/contrib/report]] plugin. I've been using it on my site; the holdup on releasing was because I hadn't yet written the docs for it. I hope you find it useful.
