Hi,

I was playing little bit with translating texts in witz scripts and it appears that it is possible to use t_("xxx") syntax like in *.cpp files (e.x. $t_("some text")).
TheIDE even scans *.witz scripts for t_(""). So far so good. But I have some questions:

- GetLngString uses cache to speed up translation. Is it possible that different texts from *.witz can have the same location in memory? Or maybe the same text can have different address each time and this will make cache grow after each translation. Maybe it is better to use non-cached version (GetLngString(GetCurrentLanguage(), (String)arg[0]))

- is it possible to detect user agent language and automatically show him proper translation?

Modified Skylark11 example:

main.cpp:

#include <Skylark/Skylark.h>
#include <plugin/sqlite3/Sqlite3.h>

#define TFILE <Skylark11/lang.t>
#include <Core/t.h>

using namespace Upp;

SKYLARK(HomePage, "")
{
	http("VAR", t_("Aborted by user."))
	    .RenderResult("Skylark11/index");
}

SKYLARK(SetLanguage, "setlanguage/*")
{
	int lang = LNGFromText(http[0]);
	if(lang)
		http.SetLanguage(lang);
	http.Redirect(HomePage);
}

struct MyApp : SkylarkApp {
	MyApp() {
		root = "myapp";
		threads = 1; // Sqlite3 does not like threads...
	#ifdef _DEBUG
		prefork = 0;
		use_caching = false;
	#endif
	}
};

Value translate(const Vector<Value>& arg, const Renderer *)
{
	if(arg.GetCount() == 1 && IsString(arg[0]))
		return GetLngString((String)arg[0]);
//		return GetLngString(GetCurrentLanguage(), (String)arg[0]);
	return arg[0];
}

INITBLOCK {
	Compiler::Register("t_", translate);
};

CONSOLE_APP_MAIN
{
#ifdef _DEBUG
	StdLogSetup(LOG_FILE|LOG_COUT);
	Ini::skylark_log = true;
#endif
	MyApp().Run();	
}



index.witz:

<html>
<body>
<a href=$SetLanguage("en-us")>EN</a>
<a href=$SetLanguage("cs-cz")>CZ</a>
<a href=$SetLanguage("pl-pl")>PL</a>
<br>
$t_("Current language"): $.language<br>
$t_("English version")<br>
$t_("Variable value"): $VAR
</body>
</html>


lang.t:

#ifdef _MSC_VER
#pragma setlocale("C")
#endif
// lang.witz

T_("Current language")
plPL("Bie��cy j�zyk")


// index.witz

T_("English version")
plPL("Wersja polska")

T_("Variable value")
plPL("Warto�� zmiennej")


// main.cpp

T_("Aborted by user.")
plPL("Przerwano na �yczenie u�ytkownika")
