From edf013952ca2d110f190dc8cd16e5529846656e4 Mon Sep 17 00:00:00 2001 From: uniboi <64006268+uniboi@users.noreply.github.com> Date: Sun, 4 Feb 2024 02:14:46 +0100 Subject: Plugin interfaces (plugins v4) (#615) Replaces the current plugin api with source interfaces. - backwards compatible - no more json in binaries (wtf) - does not rely on structs from third party libraries (wtf) - actually initializes variables - no more basically unused classes The launcher exposes almost everything required by plugins in interfaces that allow for backwards compatibility. The only thing that's passed to a plugin directly is the northstar dll HWND and a struct of data that's different for each plugin. --- primedev/plugins/interfaces/interface.h | 39 +++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 primedev/plugins/interfaces/interface.h (limited to 'primedev/plugins/interfaces/interface.h') diff --git a/primedev/plugins/interfaces/interface.h b/primedev/plugins/interfaces/interface.h new file mode 100644 index 00000000..440db5b2 --- /dev/null +++ b/primedev/plugins/interfaces/interface.h @@ -0,0 +1,39 @@ +#ifndef INTERFACE_H +#define INTERFACE_H + +typedef void* (*InstantiateInterfaceFn)(); + +// Used internally to register classes. +class InterfaceReg +{ +public: + InterfaceReg(InstantiateInterfaceFn fn, const char* pName); + + InstantiateInterfaceFn m_CreateFn; + const char* m_pName; + InterfaceReg* m_pNext; +}; + +// Use this to expose an interface that can have multiple instances. +#define EXPOSE_INTERFACE(className, interfaceName, versionName) \ + static void* __Create##className##_interface() \ + { \ + return static_cast(new className); \ + } \ + static InterfaceReg __g_Create##className##_reg(__Create##className##_interface, versionName); + +#define EXPOSE_SINGLE_INTERFACE_GLOBALVAR(className, interfaceName, versionName, globalVarName) \ + static void* __Create##className##interfaceName##_interface() \ + { \ + return static_cast(&globalVarName); \ + } \ + static InterfaceReg __g_Create##className##interfaceName##_reg(__Create##className##interfaceName##_interface, versionName); + +// Use this to expose a singleton interface.
