LuaLint Plugin for NotePad++

[Pabloko]

Hello, having to edit huge lua files lately, i quickly made a NotePad++ plugin to check integrity of lua code



FEATURES:

• Auto check .lua files when saved

• Also allow to check any file even not saved tab by Plugin menu

Its compiled with lua5.1.4

Note: This plugin only check syntactic errors on code, its not aware of programming errors.

INSTALL: Put this dll on npp plugins folder
DOWNLOAD: https://mega.nz/#!IQI3GTIB!MIrWrkneTk4l ... vNdD0TXJVY
Source code: (all code is same as NppPluginTemplate base they provide ill only dump changes)

Código: Seleccionar todo

lua_State* L;
//
// Initialize your plugin data here
// It will be called while plugin loading   
void pluginInit(HANDLE /*hModule*/)
{
	L = lua_open();
}

//
// Here you can do the clean up, save the parameters (if any) for the next session
//
void pluginCleanUp()
{
	lua_close(L);
}

extern "C" __declspec(dllexport) void beNotified(SCNotification *notifyCode)
{
	switch (notifyCode->nmhdr.code) 
	{
		case NPPN_SHUTDOWN:
		{
			commandMenuCleanUp();
		}
		break;

		case NPPN_FILEBEFORESAVE:
		{
			hello();
		}
		break;

		default:
			return;
	}
}

...

void hello()
{
    int which = -1;
    ::SendMessage(nppData._nppHandle, NPPM_GETCURRENTSCINTILLA, 0, (LPARAM)&which);
    if (which == -1)
        return;
    HWND curScintilla = (which == 0)?nppData._scintillaMainHandle:nppData._scintillaSecondHandle;
	TCHAR ext[MAX_PATH];
	::SendMessage(nppData._nppHandle, NPPM_GETEXTPART, 0, (LPARAM)ext);
	if (wcsstr((wchar_t*)ext, L".lua") != NULL) {}
	else {
		::SendMessage(nppData._nppHandle, NPPM_GETCURRENTLANGTYPE, 0, (LPARAM)&langtype);
		if (langtype != LangType::L_LUA) return;
	}
	int nLength = ::SendMessage(curScintilla, SCI_GETLENGTH, 0, NULL);
	CHAR * pBuffer = new CHAR[nLength + 1];
	::memset((void *)pBuffer, 0, sizeof(CHAR) * (nLength + 1));
	int nTempLength = (int) ::SendMessageA(curScintilla, SCI_GETTEXT, nLength + 1, (LPARAM)pBuffer);
	//lua_State* L = lua_open();
	if (luaL_loadbuffer(L, (char*)pBuffer, nLength, "LuaLint") != 0) {
		const char *err = lua_tostring(L, -1);
		//TRIM FIRST PART
		int ccstart = 0;
		for (int cc = 0; cc < (int)nLength; cc++) {
			if (err[cc] == ':') {
				ccstart = cc + 1;
				break;
			}
		}
		char linenumberstr[12];
		for (int cc = ccstart; cc < (int)nLength; cc++) {
			linenumberstr[cc - ccstart] = err[cc];
			if (err[cc] == ':')  break;
		}
		int line = atoi(linenumberstr)-1;
		::SendMessage(curScintilla, SCI_GOTOLINE, line, NULL);
		MessageBoxA(NULL, (char*)err + ccstart, "Lua Error", MB_OK);
	}
	//lua_close(L);
	nTempLength = 0;
	delete pBuffer;

my app version is :

[Pabloko]

Can u try this? https://puu.sh/yTO0r/83e847a43b.dll
Ive compiled it with weird c++ toolset, now should work

[abood1987]

I forgot to remind you that this next message appears to me first:

Knowing that I put the msvcr120.dll file In the system folder "System32" or in "C:\Program Files\Notepad++"
but the problem still occurs with me and after i clicked ok this message is showen :

[Pabloko]

Its very stange, that error means that you have to install
VC Redistributable package 2013 x86 - https://www.microsoft.com/es-es/downloa ... x?id=40784

But it not makes sense that it MSVCRT120D.dll that means DEBUG but plugin isnt compiled on debug and also /MT what should include all CRT runtime and not need external install.

Maybe its lua! Let me recompile everithing again check if works, its my firts plugin on npp https://puu.sh/yU6jI/b3571e7f76.dll

By this last modification it works fine without any MSVCRT120D.dll files "very good Pablo Gracias"

tnks m8

[Pabloko]

fine, i updated the download link on 1st post and a bit of code, it will check lua files or files where you select language>LUA

[abood1987]

Pablo
i Can Call this dll in AMS ? How ?
Because I want to use it with Scintilla Object Plugin So that this function can be called with DLL.CallFunction ?

[Pabloko]

Hmm no because this DLL has notepad++ specific api, but for your editor you can just use luac.exe, the lua compiler that converts code to bytecode. just use:

Código: Seleccionar todo

luac.exe -p filename.lua
luac -p - <input code on stdin>

It will dump errors on code, thats the same way i use to get errors.

Código: Seleccionar todo

if(luaL_loadbuffer(L, "CODE",codesize, "FILENAME")!=0) error(lua_tosting(L,-1))

It also works in native lua but executes the code...

Código: Seleccionar todo

err = loadstring("code")() --err contain error or nil of its ok

Here its a version of luac.exe with static dll (embedded) https://puu.sh/yUsRT/3883d4015e.rar

[abood1987]

ok i can used that :

nlen = Scintilla.SendMessage("Plugin1",MinTabIndex, "num",SCI_GETLENGTH, "num", 0, "num",0);
ret , text = Scintilla.SendMessage("Plugin1", MinTabIndex, "num", SCI_GETTEXT, "num", nlen+1, "pstr", nlen);

Dialog.Message("",assert(loadstring(text))());

[Pabloko]

ok i can used that :

nlen = Scintilla.SendMessage("Plugin1",MinTabIndex, "num",SCI_GETLENGTH, "num", 0, "num",0);
ret , text = Scintilla.SendMessage("Plugin1", MinTabIndex, "num", SCI_GETTEXT, "num", nlen+1, "pstr", nlen);

Dialog.Message("",assert(loadstring(text))());

Problem with that is that you actually execute the code, that can give you problems in your project, that why i suggested luac.exe

[abood1987]

can you put an apz ? Sorry I did not understand the correct way to use your file
I tried so but nothing

File.Run(_DesktopFolder.."\\aa\\luac5.1.exe", _DesktopFolder.."\\aa\\MyFile.lua", "", SW_HIDE, true);

[Pabloko]

Well i tried myself and it not so simple as error messages are put into stderr, you have to use commandline plugin or something like that, for simplicity i just compiled a dll that does this task

	int lua_lualint(lua_State* L) {

		lua_State* Ls = lua_open();

		const char * pBuffer = lua_tostring(L, 1);

		const char * fileName = lua_tostring(L, 2);

		if (luaL_loadbuffer(Ls, (char*)pBuffer, strlen(pBuffer), fileName) != 0) {

			const char *err = lua_tostring(Ls, -1);

			lua_pushstring(L, err);

		}

		else lua_pushnil(L);

		lua_close(Ls);

		return 1;

	}

	// Ejemplo de función exportada.

	{

		lua_register(L, "lualint", lua_lualint);

		return 0;

With sci, you should parse this message and use sci api to print it better



Use annotations to display the message and markers if you want

Código: Seleccionar todo

SCI_ANNOTATIONSETTEXT(int line, const char *text)
SCI_ANNOTATIONSETSTYLE(int line, int style)
SCI_MARKERADD(int line, int markerNumber)
...

I sould did the same on notepad++ editor but i did it quick for me, didnt think about releasing it.

yes that is good idea
