Well, generate classes and load/reload them without recompiling anything would be perfect, but perhaps it's
not possible in a system like Vala (i mean, without an underlying runtime).
Compiling some plugin/library on-the-fly and reload them is an acceptable solution, but it's not a very
The goal is to let a user define new types/classes through a web interface, and having some web services,
serving as entry points in the system, able to manipulate (strongly typed search, sort, and so on) these
user-defined classes/objects without recompiling and restarting the main app.
To avoid the lost of these user-defined objects after an app or system restart, perhaps they can persist on
the disk using a library like Catalina.

you want to have add functions and reload module without recompiling?
I'm wondering what would be the "right" way to generates
code/classes at runtime, and reload it into the running program.
I thought to use the modules/plugin approach
(http://live.gnome.org/Vala/TypeModules) the following way :
- generate code than can be reloaded (plugin code, [ModuleInit]) using some kind of StringBuilder
- flush it to a file
- compile this file either by forking a valac compiler or perhaps
using directly libvala (possible ?)
- reload the resulting plugin binary into the app
There's probably a better way to accomplish this kind of task.
Any idea / suggestion ?
Thanks for helping :)
