What most of you take as prototype is wordpress. And there are quite
some plugins requiring you to modify your templates. If a plugin is to
actually *output* anything into a template, it might have a few template
files that define an outcome. Then, you must only {% include %} that
file in an appropiate place. Seems flexible enough to me, while newbies
do only have to copy-paste the include tag into their template.
Of course, if the templating engine is solid, themes are to be released,
and, as with wordpress, there can be many themes like K2, that are
already aware of many most-used plugins.
Just to make it clear. It's still the template's job to take care of
display. The plugin must not *modify* a single source file, as stated above.
And, Forest, if you provide enough hooks where plugins can join the
app's flow (like the plugin middleware, and the template imports),
you're done predicting the future. We just have to think about the right
places where to place hooks.
Actually, is there anyone *really* able to contribute some code to this
endeavour?
