Subject Splitting cocoon.xconf: done
Date Wed, 29 Dec 2004 20:51:22 GMT
Hi all,

I just committed the new feature that allows cocoon.xconf to be split 
into small parts. There is a new <include src=""/> statement that 
includes either a roles file or a xconf file. A minimal sourceresolver 
is setup at cocoon boot time that provides the "resource:" and 
"context:" protocols to fetch files (relative files are equivalent to 
"context:").

This allow the main cocoon.xconf file to be a list of includes of the 
main core components and block-provided xconf files, each including its 
specific roles when needed.

For this to be really useful, I refactored ECM++ so that a component 
selector can be declared several times. Each block can then easily 
provide its own source factories, input modules, taglibs, etc.

The only remaining problem is XSP because some blocks provide 
logicsheets that aren't handled by a selector and therefore require the 
use of xpatch to inject the logicsheet declaration at the right place.

This new feature allows to very easily activate/deactivate blocks (just 
comment or remove the corresponding <include>) and add user-provided 
components without having to mix them with the cocoon-provided ones. 
This may also allow us to provide again binary distributions, which will 
make it easier for newcomers.

The include feature is also available in the sitemap, but more work is 
needed there as labels and mime-types are ignored in included files.

Enjoy,
Sylvain
