| pcb has a plug-in mechanism that allows developers to add or modify its functionality. Plugins can add pcb actions, hook into the GUI HIDs, create new exporters, and more. For a tutorial on the basics of writing and installing a pluging, see the hello world example on the [[geda:pcb_developer_introduction_2| pcb Developer Introduction]] page. This page will discuss how plugins interact with the pcb system. | pcb has a plug-in mechanism that allows developers to add or modify its functionality.

| + | pcb plugins are essentially shared libraries that pcb will load at run-time. Because of this, they can be written in just about any language that can be compiled into a shared library. I haven't verified anything other than C and C++, but it ought to be possible. If you've successfully written a plugin in another language, let me know! | ||
| + | At runtime, pcb scans several directories for .so/.dll files. If it finds one, it opens it and looks for a couple of symbols: "hid_<file basename>_init" and "pcb_plugin_init". If it finds one, it executes it as a function. These functions are responsible for registering the code they represent with pcb. | ||
