Notepad++ Language List

Michael Vincent

I have a plugin where I need to know the Notepad++ language list. I see “Notepad_plus_msgs.h” which is part of the template plugin has:

enum LangType {L_TEXT, L_PHP , L_C, L_CPP, L_CS, L_OBJC, L_JAVA, L_RC,\
[...]

And that would work if there was some way to get the enum “name” from the LangType array (and then just strip the “L_”). Other thoughts are to just create an array of strings and (pseudo-code follows):

for i = (0 .. 85) {
    langArray[i] = NPPM_GETLANGUAGENAME (i)
}

But I’m using 85 because I “know” there are 86 elements in the languages enum. In fact, if I ask NPP for language 86, it replies with “Normal Text” (which is language 0) so a proper while loop returning “i” until NPPM_GETLANGUAGENAME (i) returns a NULL wouldn’t work. Is there a NppGetNumberOfLanguages() call I’m not familiar with?

As you can probably tell, C++ isn’t my “first language” so it’s quite possible I’m missing something obvious. Currently, I’m just defining my own array of strings and “hardcoding” the enum LangType “names” sans the “L_”. I was hoping to have something a bit more dynamic like the for loop example above.

Cheers.

what about something like this pseudo code

enum LangType {L_TEXT, L_PHP , L_C, ... L_EXTERNAL};

for ( int i=0; i<LangType.L_EXTERNAL; i++ )
{
   langArray[i] = NPPM_GETLANGUAGENAME (i)
}

L_EXTERNAL should be always the last entry in LangType

L_EXTERNAL should be always the last entry in LangType

In fact you’re correct:

"Notepad_plus_msgs.h”:

			   // The end of enumated language type, so it should be always at the end
			   L_EXTERNAL};

So your code makes perfect sense and it was something obvious I was missing! Thanks!

SOLVED!

Cheers.

Here is the actual code I used:

vector<string> lang_menu;

std::string wstrtostr( const std::wstring &wstr )
{
    // Convert a Unicode string to an ASCII string
[...]


[...]
    lang_menu.clear();
    for ( int i = 0; i <= L_EXTERNAL; i++ )
    {
        TCHAR langName[MAX_PATH];
        SendMessage( nppData._nppHandle, NPPM_GETLANGUAGENAME, i, ( LPARAM ) langName );
        lang_menu.push_back( wstrtostr( langName ));
    }
[...]

Thanks a million!

Cheers.

The disadvantage of your method is that you have to update your Notepad_plus_msgs.h file and recompile and redistribute your plugin everytime a new programming language is added to Notepad++.

I solved the same problem in my AutoCodepage plugin by querying language names in a repeat…until loop, that terminates if the returned language name equals to External. This way I don’t need to recompile and redistribute my plugin only because of extended programming language support of Notepad++.

Additional hint: My loop doesn’t process L_USER and L_JS.

I may “borrow” that :-)

Thanks!

It’s in Pascal! argh! I converted your recommendation into C++ (i think):

    TCHAR langName[MAX_PATH];
    lang_menu.clear();
    do
    {
        SendMessage( nppData._nppHandle, NPPM_GETLANGUAGENAME, i, ( LPARAM ) langName );
        lang_menu.push_back( wstrtostr( langName ));
        i++;
    } while ( strcmp( wstrtostr( langName ).c_str(), "External" ) != 0 );
    lang_menu.push_back( "GLOBAL" );

This way no dependence on L_EXTERNAL or the Notepad_plus_msgs.h file.

Thanks for taking the time to recommend that!

Cheers.
