<br class="">
I have working on the source code of sane-backends, I found the macro<br class="">
SANE_I18N is used to sane’s localization. But I just found the follow<br class="">
lines of it’s define<br class="">
<br class="">
#ifndef SANE_I18N<br class="">
#define SANE_I18N(text) text<br class="">
#endif<br class="">
<br class="">
The above lines, dose nothing. So I wonder how SANE_I18N translate<br class="">
these backends?<br class="">
</blockquote>
<br class="">
The backends don't translate. It's the responsibility of the *frontend*<br class="">
to translate the strings. The SANE_I18N macro is only the marker we use<br class="">
to tell xgettext which strings should be translated. These strings end<br class="">
up in po/sane-backends.pot.<br class="">
<br class="">
The reasoning behind making the frontend responsible for translation is<br class="">
that the backend may be executing remotely (e.g. via saned). You don't<br class="">
want to get the translations suitable for a remotely executing process.<br class="">
This process may execute under a different LANG setting than your local<br class="">
SANE frontend.<br class="">
<br class="">
Let's say you run your frontend with LANG=zh_CN and scan via the net<br class="">
backend on a server that just happens to run saned with LANG=fr_FR.<br class="">
Would you be happy with French messages? Probably not ;-)<br class="">
<br class="">
Hope this helps,<br class="">
