xgettext parametrization (was: Re: xgettext deficiency?)

Hello Clytie,

Thanks for bringing this up to a forum where I can help.

There are three things that you could do about it:

1) If this is the only call to 'dgettext' in your program, or if all the
   'dgettext' arguments should not be added to the POT file, then you can
   pass to xgettext a set of keywords to look for, that does not include
   'dgettext'. Like this:

      xgettext --k --keyword=gettext --keyword=gettext_noop --keyword=_ ...

2) If only this particular call to 'dgettext' should be omitted from the
   POT file, you can hide the call in a C macro or inline C function, like
   this:
 
      #define gtk20_gettext(string) dgettext("gtk20", string)
      gtk20_gettext("calendar:week_start:0")

3) Last not least, you can always modify po/Makefile.in.in to postprocess
   the POT files in particular ways. For example, you could pipe it through

      msggrep -v --msgid -E -e '^calendar:week_start:0$'

   to exclude exactly this particular msgid.
