Chris,
Yes, I've read your code, and am doing very much the same re initial page,
rendering, metadata checks. The only additional steps I'm taking are to:
1) verify that the syntax actually still exists in the wiki
2) if not, then I'm removing (or at least clearing) the metadata flag so
that I don't retry in the future
The advantage of the above is that I "clean up" and return to a single cache
for pages where the syntax has been removed.
The disadvantage of the above is that I have an extra syntax verification
every time. (But only where the metadata flag is still set.)
Thank you--I think I am satisfied with the plugin's function for the
present. If I get energetic, I may clean up the comments and post it
somewhere.
Thanks to all,
Todd Augsburger

I get around this by ensuring the syntax plugin component writes a
metadata key to indicate its presence in the page. That is easy for the
include plugin as there is a defined key - relation hasPart. A bigger
problem is not knowing if that relation hasPart was put there by the
include plugin of by something else. Take a look at the dublin core
pages to see if there are any metadata keys which match your needs. If
not, make one up.
If you take a look at the code I provided a link to earlier, you'll see
the first few lines in processing the event are to do with deciding
whether or not "the plugin" has any interest in the page. I think the
checks are:
- is it a wiki page?
- is it being rendered for xhtml (or whatever render modes the plugin
supports).
- is there a metadata key that the plugin recognises
if any of these are failed the plugin exits immediately.
the plugin then calculates the correct cache name and modifies the cache
name on the cache object to the new name. DW's cache handling then
determines whether or not to use it. You can also expire the cache
there and then or add additional dependencies for DW to check (both of
these facilities are used by the include plugin).
Cheers,
Chris
