doc/todo/pagestats:_ability_to_limit_to_links_from_certain_pages.mdwn



The among branch in my git repository refactors IkiWiki::Render a
bit, then uses this refactoring to add a [[ikiwiki/directive/pagestats]]
parameter among that will only count links from pages that match a
given [[ikiwiki/PageSpec]]. From its documentation:

The optional among parameter limits counting to pages that match a
[[ikiwiki/PageSpec]]. For instance, to display a cloud of tags used on blog
entries, you could use:
   \[[!pagestats pages="tags/*" among="blog/posts/*"]]

or to display a cloud of tags related to Linux, you could use:
   \[[!pagestats pages="tags/* and not tags/linux" among="tagged(linux)"]]


Suggestions for a better parameter name are welcome. --[[smcv]]
