I have several localized texts in src.tpp and would like to load them in run-time according to the current user language.
The easiest way I can think of, is to do it with a code like this:

PromptOK(String("MyProject/src/About$") + GetLanguageCode(GetCurrentLanguage()));

And a function GetLanguageCode() is a slightly modified LNGasText():

String GetLanguageCode(int d)
{
	String result;
	int c = (d >> 15) & 31;
	if(c) {
		result.Cat(c + 'a' - 1);
		c = (d >> 10) & 31;
		if(c) {
			result.Cat(c + 'a' - 1);
			c = (d >> 5) & 31;
			if(c) {
				result.Cat('-');
				result.Cat(c + 'a' - 1);
				c = d & 31;
				if(c) result.Cat(c + 'a' - 1);
			}
		}
	}
	c = (d >> 20) & 255;
	return result;
}

The change is that it does not add charset name and returns lower-case language code, exactly as TPP editor set language codes for topics.

Am I inventing a wheel?

Maybe use this code:

String s = String("MyProject/src/"+Topic+"$") + String(ToLower(LNGAsText(GetCurrentLanguage()& 0xfffff)));

But I use extended form of help request

Vector<String> Topic = Split(topic, '#'); 
String s = String("MyProject/help/"+Topic[0]+"$") + String(ToLower(LNGAsText(GetCurrentLanguage()& 0xfffff)))+"#"+String(Topic[1]);

You can use:

LNGAsTxt(SetLNGCharset(GetCurrentLanguage(), CHARSET_DEFAULT))

Well... After some tweaking I now load my QTF's like this:

Topic GetTopicLNG(const String &path) {
	return GetTopic(path + "$" + ToLower(LNGAsText(GetCurrentLanguage()).Left(5)));
}
....

PromptOK(GetTopicLNG("MyProject/src/About"));

May be some kind of language sensitive loading function should be in the default Topic library?

Sounds good Smile

Should there be used the trick to remove charset too?

Yes. That is why I have .Left(5) from the result of LNGAsText().

This would work, right?:

Topic GetTopicLNG(const String &path) {
	return GetTopic(path + "$" + ToLower(LNGAsTxt(SetLNGCharset(GetCurrentLanguage(), CHARSET_DEFAULT)));
}

Maybe we could add something like

int LNGNoCharset(int c)
{
    return SetLNGCharset(GetCurrentLanguage(), CHARSET_DEFAULT));
}

to avoid future confusion too Smile

Looks like it. With some minor corrections of course Smile

Topic GetTopicLNG(const String &path) {
	return GetTopic(path + "$" + ToLower(LNGAsText(SetLNGCharset(GetCurrentLanguage(), CHARSET_DEFAULT))));
}

I am not sure about the second one though... May be with a longer name it would be more easy to use:

int GetCurrentLanguageIdWithDefaultCharset()
{
    return SetLNGCharset(GetCurrentLanguage(), CHARSET_DEFAULT));
}

But I do not actually see where this shortcut would be useful.
