[Cppcms-users] Plugins and templates

Hallo,

for one of my applications I'm currently developing a plugin system. The
plugin is deployed as shared object and contains some methods that work
with a content class that is derived from cppcms::base_content.
Now I'm looking for a way to deliver the required cppcms template
alongside the plugin (e.g., for a way to plug the required view into
cppcms for rendering the plugin's content).
To achieve this, I first wrote a template file for the common layout
that the output of all plugins share and compiled it into the main
application. Now each plugin has an own template file which derives from
the master view and overrides some template functions to customise
output. The template file is compiled as shared object after parsing it
with cppcms_tmpl_cc.
What I want to do now is to load the shared object and use the views
contained in it.
The problem I stumbled upon is, that cppcms complains that the named
skin already exists when I try to load the so file as described in the
online documentation via the config.js file, and of course it does,
because the master view compiled in the main binary shares the skin with
the view in the shared object, because this view only extends the master
template.
One solution that came to my mind is to not specify a skin in the master
template and instead passing one with -s to cppcms_tmpl_cc to create
shared objects that contain the whole stuff but all have another skin to
be able to load a shared object file for each plugin and use them side
by side and specifying the skin for the plugin in the render method.

Is there another, perhaps more elegant method to achieve the behaviour I
need?

Thanks,
Julian
