Plugins

In the kickoff article of this series, I defined some fundamental concepts we can use when talking about plugins.

Understanding how plugins may work in C will help us understand how to implement cross-language plugins in the future.

I’ve re-implemented the htmlize program from the previous article entirely in C, including a plugin mechanism and the same two sample plugins.

Plugins in C are almost always implemented as DSOs (Dynamic Shared Objects, aka. shared libraries, or DLLs on Windows).

Note that due to the nature of dynamic linking on Linux, plugins don’t have to actually link with the db.o object.

Are you using the latest plugins?

In the future, Firefox will upgrade plugins for you.

Does Celluloid support plugins?
