New CPlugin ABI

There is a new ABI for writing nwnx4 plugins, that should be much simpler to implement for languages other than C++.

The new ABI is defined here: https://github.com/nwn2dev/nwnx4/blob/main/include/nwnx_cplugin.h

If you are writing a C or C++ plugin, you can directly include this file in your C / C++ project. Most compiled languages can generate C-compatible ABIs, so if your plugin is written in another language, you will need to "translate" this file for your language.

Currently there are two plugins that use the new CPlugin ABI:

• https://github.com/nwn2dev/nwnx4/tree/main/src/plugins/xp_example_cplugin: This C++ plugin is just an example and does nothing really useful (except validating ABI tests).
• https://github.com/nwn2dev/nwnx4-plugins-xp_rpc: This plugin written in Go replaces the xp_rpc plugin that was shipped with nwnx4 (see below).

nwnx_include.nss has been updated to provide additional functions for querying information about the new CPlugins.

Of course, the previous ABIs are still supported and older plugins will continue to be compatible with NWNX4.

Removed RPC

Unless you were using the xp_rpc plugin, these changes should not affect you.

• Removed RPC logging facilities
  • RPC plugins could log message through the nwnx4 logging system to nwnx.txt. This is no longer the case.
  • RPC plugins must now implement their own logging system, just like any other nwnx4 plugin
• Removed the xp_rpc plugin
  • The RPC plugin can now be found at https://github.com/nwn2dev/nwnx4-plugins-xp_rpc

Other changes

• xp_pickpocket: Fixed the NWScript function PickpocketContinue to reflect what it is supposed to do
