兴趣是最好的老师。周末晚上熬夜到半夜十二点多，花了几个钟头给NDD制作了一款AI搜索问答插件，时间仓促界面较丑，后续插件代码开源并维护和美化。Notepad记事本工具挺常用的，把AI接口接入进来使用起来方便多啦，直接在上面搜索问答。这里记录下详细过程，分享给有需要的小伙伴。

无需注册和配置，只需我把动态库发您，放入插件目录即可，使用我的后台服务可以直接使用。

ndd-chat-ai: NDD（NotePad--）的聊天机器人插件

实现效果截图：

 

环境准备

首先得有一个AI的后台接口服务。好在我已具备，部署在了免费的replit。如果你有公有云服务器资源，可以也部署一个AI的后台接口服务。如果没有，免费的repit也很好用。

下载NDD源码，准备好编译环境（msvc2019工具链+QT5.12以上版本）。

以下是我的replit后台截图: 

NDD插件制作

插件主要功能实现类

按照NDD插件制作说明制作一个插件，点击菜单后弹出一个QDockWidget停靠窗口(实用工具窗口)。停靠在主窗口的左侧。NDDMyPlugin主功能实现类如下：

插件接口类

该类主要是插件框架层接口的实现。这个简单，基本就是按NDD插件的说明文档制作。

#include <qobject.h>
#include <qstring.h>
#include <pluginGl.h>
#include <functional>
#include <qsciscintilla.h>

#if defined(Q_OS_WIN)
	#if defined(NDD_EXPORTDLL)
		#define NDD_EXPORT __declspec(dllexport)
	#else
		#define NDD_EXPORT __declspec(dllimport)
	#endif
#else
	#define NDD_EXPORT __attribute__((visibility("default")))
#endif

#ifdef __cplusplus
	extern "C" {
#endif

	NDD_EXPORT bool NDD_PROC_IDENTIFY(NDD_PROC_DATA* pProcData);
	NDD_EXPORT int NDD_PROC_MAIN(QWidget* pNotepad, const QString& strFileName, std::function<QsciScintilla* ()>getCurEdit, NDD_PROC_DATA* procData);


#ifdef __cplusplus
	}
#endif
NDDMyPlugin *nddMyPlugin = nullptr;
static NDD_PROC_DATA s_procData;
static QWidget* s_pMainNotepad = nullptr;
std::function<QsciScintilla* ()> s_getCurEdit;

bool NDD_PROC_IDENTIFY(NDD_PROC_DATA* pProcData)
{
	if(pProcData == NULL)
	{
		return false;
	}
	pProcData->m_strPlugName = QObject::tr("Chat AI Plug");

}

//则点击菜单栏按钮时，会自动调用到该插件的入口点函数。
//pNotepad:就是CCNotepad的主界面指针
//strFileName:当前插件DLL的全路径，如果不关心，则可以不使用

//pProcData:如果pProcData->m_menuType = 0 ,则该指针为空；如果pProcData->m_menuType = 1，则该指针有值。目前需要关心s_procData.m_rootMenu
//开发者可以在该菜单下面，自行创建二级菜单
int NDD_PROC_MAIN(QWidget* pNotepad, const QString &strFileName, std::function<QsciScintilla*()>getCurEdit, NDD_PROC_DATA* pProcData)

    if (pProcData == nullptr)
    {
        return 1;
    }

    s_pMainNotepad = pNotepad;
    s_procData = *pProcData;
    s_getCurEdit = getCurEdit;

	//如果pProcData->m_menuType = 1;是自己要创建二级菜单的场景。则通过s_procData.m_rootMenu 获取该插件的菜单根节点。
	//插件开发者自行在s_procData.m_rootMenu下添加新的二级菜单项目
    //QMenu* menu = s_procData.m_rootMenu;
    if (!nddMyPlugin)
    {
        nddMyPlugin = new NDDMyPlugin(s_pMainNotepad, strFileName, nullptr, s_pMainNotepad);

        nddMyPlugin->getViewMenu(s_procData.m_rootMenu);
        nddMyPlugin->setScintilla(s_getCurEdit);

注意事项

由于使用了https访问网络，默认情况下会缺少两个库（libcrypto-1_1-x64.dll和libssl-1_1-x64.dll）。打包时需要把这两个动态库添加进来，否则运行不起来，运行会报错Process finished with exit code -1073741701 (0xC000007B)。该错误通常是由于所需的库文件（例如.dll文件）不存在或无法加载造成的，有可能是程序需要的特定版本的运行库缺少或者缺失了 32 位或 64 位的运行库。
