Hi!
I use wikipp as my starting point.
--------
config.js:
"wikipp" : {
//trimmed off
"disable_registration" : false,
"languages" : {
"en" : "en_US.UTF-8",
"tw" : "zh_TW.UTF-8"
},
},
"localization" : {
"backend" : "icu",
"locales" : [ "en_US.UTF-8", "zh_TW.UTF-8" ],
"messages" : {
"paths" : [ "/usr/local/share/locale","./locale" ],
"domains" : [ "wikipp" ]
}
}
--------
tw.po:
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"X-Generator: Lokalize 1.2\n"
"Plural-Forms: nplurals=2; plural=(n != 1);\n"
msgid "LANG"
msgstr "繁體中文"
--------
After running make and make install, file "wikipp.mo" does exist in directories
/usr/local/share/locale/tw/LC_MESSAGES/
and
./locale/tw/LC_MESSAGES/
--------
master.cpp:
master::master(wiki &_w) :
application(_w.service()),
wi(_w),
locale_name(wi.locale_name)
{
conn = wi.conn;
cppcms::json::object langs=settings().get("wikipp.languages",cppcms::json::object());
for(cppcms::json::object::const_iterator i=langs.begin(),e=langs.end();i!=e;++i) {
std::string lname;
if(i->first=="en")
lname="English";
else {
lname=_("LANG").str(service().generator().generate(i->second.str()));
if(lname=="LANG")
{
//Non-English contents always go here. Never get translated!
BOOSTER_DEBUG("not translated:") << i->first << "," << i->second.str();
lname=i->first;
}
}
languages[lname]=settings().get<std::string>("wikipp.script") +"/"+ i->first.str();
}
media=settings().get<std::string>("wikipp.media");
cookie_prefix=settings().get("session.cookies.prefix","cppcms_session")+"_";
}
void master::current_language(content::master &m,std::string const &locale_name)
{
m.current_language=_("LANG").str(service().generator().generate(locale_name));
}
-----------
The log:
2013-08-03 12:08:43; not translated:, debug: tw,zh_TW.UTF-8 (master.cpp:112)
2013-08-03 12:08:43; not translated:, debug: tw,zh_TW.UTF-8 (master.cpp:112)

2013-08-03 12:08:43; not translated:, debug: tw,zh_TW.UTF-8 (master.cpp:112)
When
void master::current_language(content::master &m,std::string const &locale_name)
is called by page.cpp, the following exception is thrown:

----
To see what happen, I change config.js to
"localization" : {
//"locales" : [ "en_US.UTF-8", "zh_TW.UTF-8" ],
"locales" : [ "zh_TW.BIG5" ],
"messages" : {
"paths" : [ "/usr/local/share/locale","./locale" ],
"domains" : [ "wikipp" ]
}
,"disable_charset_in_content_type":true
}
It is weird! The rendered English html page is never changed - Content-Type is always "charset=utf-8":
<head>
<title>My Title</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
