## š ļø **Plugin Development**
### **Plugin API**
**Communication Method**: Windows Messages
**Language**: C++ (primary), others via FFI
**API Version**: Notepad++ Plugin Interface v2.0+
### **Basic Plugin Structure**
```cpp
// Minimal plugin skeleton
#include "PluginInterface.h"
// Plugin name
const TCHAR* PLUGIN_NAME = L"MyPlugin";
// Required exports
extern "C" __declspec(dllexport) void setInfo(NppData notepadPlusData);
extern "C" __declspec(dllexport) const TCHAR* getName();
extern "C" __declspec(dllexport) FuncItem* getFuncsArray(int *nbF);
extern "C" __declspec(dllexport) void beNotified(SCNotification *notifyCode);
extern "C" __declspec(dllexport) LRESULT messageProc(UINT Message, WPARAM wParam, LPARAM lParam);
extern "C" __declspec(dllexport) BOOL isUnicode();
// Implementation...
```
---
### **Plugin Communication**
**Message Types**:
- `NPPM_*` - Notepad++ messages (file operations, UI control)
- `SCI_*` - Scintilla messages (editor control, text manipulation)
- `WM_*` - Windows messages (standard Win32)
**Example Operations**:
```cpp
// Get current file path
TCHAR path[MAX_PATH];
::SendMessage(nppData._nppHandle, NPPM_GETFULLCURRENTPATH, MAX_PATH, (LPARAM)path);
// Get editor text
int length = ::SendMessage(nppData._scintillaMainHandle, SCI_GETLENGTH, 0, 0);
char* text = new char[length + 1];
::SendMessage(nppData._scintillaMainHandle, SCI_GETTEXT, length + 1, (LPARAM)text);
// Insert text
::SendMessage(nppData._scintillaMainHandle, SCI_ADDTEXT, strlen(text), (LPARAM)text);
```
