Programming Notepad++ plugins

In this article we will show how to program Notepad++ plugins using a simple Hello World program. For this you need Visual Studio from Microsoft. It is available for free at

Download the Notepad++ Plugin Template and unzip it. Then open the file NppPluginTemplate.vcxproj with Visual Studio.

The name of the plugin is defined in the PluginDefinition.h file.

const TCHAR NPP_PLUGIN_NAME[] = TEXT("Notepad++ plugin template");

The template already contains two functions. These are defined in the same PluginDefinition.h file.

// // Your plugin command functions // void hello(); void helloDlg(); #endif //PLUGINDEFINITION_H

The implementation of the functions is located in the PluginDefinition.cpp file.

void hello() { // Open a new document ::SendMessage(nppData._nppHandle, NPPM_MENUCOMMAND, 0, IDM_FILE_NEW); // Get the current scintilla int which = -1; ::SendMessage(nppData._nppHandle, NPPM_GETCURRENTSCINTILLA, 0, (LPARAM)&which); if (which == -1) return; HWND curScintilla = (which == 0)?nppData._scintillaMainHandle:nppData._scintillaSecondHandle; // Say hello now : // Scintilla control has no Unicode mode, so we use (char *) here ::SendMessage(curScintilla, SCI_SETTEXT, 0, (LPARAM)"Hello, Notepad++!"); }

Here a new text file is created and "Hello, Notepad++!" is written into this file.

void helloDlg() { ::MessageBox(NULL, TEXT("Hello, Notepad++!"), TEXT("Notepad++ Plugin Template"), MB_OK); }

The helloDlg() function opens a textbox with the same message.

The two functions are made available with the following code in the navigation bar under Plugins>>Notepad++ plugin template.

void commandMenuInit() { setCommand(0, TEXT("Hello Notepad++"), hello, NULL, false); setCommand(1, TEXT("Hello (with dialog)"), helloDlg, NULL, false); }

Now click Start without debugging. The file NppPluginTemplate.dll is now created and is available in the solution folder under x64\Debug.

Copy the NppPluginTemplate.dll into the Notepad++ installation folder under Notepad++\plugins\NppPluginTemplate.

If you now start Notepad++ your plugin with the two functions is available under the Plugins Menu.
