yes of course

ok, i said previously that my programs are working. With little bit more
examination i realised , that they are working only occasionaly . 
Because i feel the problem is on the gettext side i'm giving description
of all that.


#include <stdio.h>

#include <locale.h>

     #include <libintl.h>
     #define _(String) gettext (String)
     #define gettext_noop(String) (String)
     #define N_(String) gettext_noop (String)


#define PKG   "gettext_ak"
#define LOCDIR "/zz/mysrc/tests/intl001/locale"

extern int  _nl_msg_cat_cntr;

int main  () {
        char o[400] ;

        printf ( "* * setlocale:      %s\n"  , setlocale ( LC_ALL, "") ) ;

        ++_nl_msg_cat_cntr;
        printf ( _("%s goes from hollywood\n") , _("frankie") ) ;
        printf ("\n" ) ;

        ++_nl_msg_cat_cntr;
        printf ( _("%s goes from hollywood\n") , _("frankie") ) ;
        printf ("\n" ) ;

//        setenv ("LC_ALL", "no", 1);         // this doesn't work
//        printf ( "* * setlocale:      %s\n"  , setlocale ( LC_ALL, "") ) ;
        setenv ("LANGUAGE", "de", 1);
        ++_nl_msg_cat_cntr;
        printf ( _("%s goes from hollywood\n") , _("frankie") ) ;

        return 0;
}

-----------------------------------------
I'm not supllying message catalogs, because they contain just random strings,
to show that it works. ( just say if you want them and i will send *.tgz)

gcc gettext_ak.c

starting position is "C" .... this means:  unset LC_* , LANGUAGE , LANG;
So we have clean environment and can start right on. Now comes listing of
commands and  ... Please read first comments under the dash-line and return
here ( if you will have enough courage )

Comments : Previous code is not very readable ( it lacks my PS1 highlighting ),
so summary of all that is ( i added one more line to this table ) :

LANG | LC_ALL  | LANGUAGE | setlocale | translated | force cs_CZ | force de
 --      --         --          C          no            no          no
 --    cs_CZ        --        cs_CZ       into cs        yes         yes
 --    en_US        --        en_US        no            yes         yes
 --    de_DE        --        (null)       no            no          no
 --    de_DE        de        (null)       no            no          no
 --     sk          de         sk         into de        yes         yes
 --      --         cs          C          no            no          no

What this means ??
1) i hoped LANGUAGE has higher priority then anything , but this shows it's
   not true. It's enough to set some lower priority LC_anything to illegal 
string
   and LANGUAGE loses 
2) gettext doesn't work even when LC_* are unset . Because it cannot be forced
   to other language - line 1 and the last one !! Isn't that bug ?
3) my system doesn't seem to understand de_DE . During mandrake instalation
   i choosed just en,cz,sk . It means that locale/de/* doesn't contain all that
   monetary,ctime,numbers stuff.  But locale/de/LC_MESSAGES/* exist !!!!
   But gettext is refusing to work . Why ?? I think that catalogs should be
   enough to work .


Let me know if you feel this is/is not a bug.

Other programs works exactly the same way. I previously said they don't work
at all. That was probably by several accidents that probably joined together
        1) it's not obvious for beginner that state of $LANGUAGE is not
                reflected in output of locale(3) .. So month ago, when i
                verified my tests with locale, i had no chance to recognize 
                the reason. ( i had LANGUAGE=en_US , but diagnostic program
                didn't tell  - maybe it should be considered a bug )
        2) my test were usually executed in new shell, so everytime i spawned
                new xterm , it had executed my .bashrc and ... 
        3) as a bad luck i probably didn't tried ls --help in the same shell
                as my programs, but in different ones .
        4) i was very often experimenting with hu_HU as this is favourite
                language of my friend ( he understand just same 20 words , but 
                he like to see it on the screen ) 
So i do apologize about that , but the fault is not completely on my side.
Anyway i'm happy that i can finaly run gimp in czech !


Good night , i'm completely tired
