Smarty

I'm not exactly clear after reading the documentation.
Can I set a handler to read config vars from database table, f.e.?

[U.Tews]

Config files are text which is parsed and compiled like a template source. It can be loaded from other resources same way like templates.

It might be possible to create a custom resource which for example reads a mysql table where each row is assigned to a config variable.

The major challenge would be how a cached template could detect modifications of template var and rebuild the cache.

Cached template shouldn't detect anything The point of caching.

Anyway, thanks for assurance. My idea is to write response handler with Smarty as its body content producer, and use Smarty config functionality to set up site variables.
I'll be fine with files for a while, but eventually I'd like to move to more accessible storage.
