<P>
After preparing the sources, the programmer creates a PO template file.
This section explains how to use <CODE>xgettext</CODE> for this purpose.
</P>
<P>
<CODE>xgettext</CODE> creates a file named <TT>‘<VAR>domainname</VAR>.po’</TT>. You
should then rename it to <TT>‘<VAR>domainname</VAR>.pot’</TT>. (Why doesn't
<CODE>xgettext</CODE> create it under the name <TT>‘<VAR>domainname</VAR>.pot’</TT>
right away? The answer is: for historical reasons. When <CODE>xgettext</CODE>
was specified, the distinction between a PO file and PO file template
was fuzzy, and the suffix <SAMP>‘.pot’</SAMP> wasn't in use at that time.)

Additional keyword to be looked for (without <VAR>keywordspec</VAR> means not to
use default keywords).
<A NAME="IDX183"></A>
<A NAME="IDX184"></A>
If <VAR>keywordspec</VAR> is a C identifier <VAR>id</VAR>, <CODE>xgettext</CODE> looks
for strings in the first argument of each call to the function or macro
<VAR>id</VAR>. If <VAR>keywordspec</VAR> is of the form
<SAMP>‘<VAR>id</VAR>:<VAR>argnum</VAR>’</SAMP>, <CODE>xgettext</CODE> looks for strings in the
<VAR>argnum</VAR>th argument of the call. If <VAR>keywordspec</VAR> is of the form
<SAMP>‘<VAR>id</VAR>:<VAR>argnum1</VAR>,<VAR>argnum2</VAR>’</SAMP>, <CODE>xgettext</CODE> looks for
strings in the <VAR>argnum1</VAR>st argument and in the <VAR>argnum2</VAR>nd argument
of the call, and treats them as singular/plural variants for a message
with plural handling. Also, if <VAR>keywordspec</VAR> is of the form
<SAMP>‘<VAR>id</VAR>:<VAR>contextargnum</VAR>c,<VAR>argnum</VAR>’</SAMP> or
<SAMP>‘<VAR>id</VAR>:<VAR>argnum</VAR>,<VAR>contextargnum</VAR>c’</SAMP>, <CODE>xgettext</CODE> treats
strings in the <VAR>contextargnum</VAR>th argument as a context specifier.
And, as a special-purpose support for GNOME, if <VAR>keywordspec</VAR> is of the
form <SAMP>‘<VAR>id</VAR>:<VAR>argnum</VAR>g’</SAMP>, <CODE>xgettext</CODE> recognizes the
<VAR>argnum</VAR>th argument as a string with context, using the GNOME <CODE>glib</CODE>
syntax <SAMP>‘"msgctxt|msgid"’</SAMP>.
<BR>
Furthermore, if <VAR>keywordspec</VAR> is of the form
<SAMP>‘<VAR>id</VAR>:...,<VAR>totalnumargs</VAR>t’</SAMP>, <CODE>xgettext</CODE> recognizes this
argument specification only if the number of actual arguments is equal to
<VAR>totalnumargs</VAR>. This is useful for disambiguating overloaded function
calls in C++.
<BR>
Finally, if <VAR>keywordspec</VAR> is of the form
<SAMP>‘<VAR>id</VAR>:<VAR>argnum</VAR>...,"<VAR>xcomment</VAR>"’</SAMP>, <CODE>xgettext</CODE>, when
extracting a message from the specified argument strings, adds an extracted
comment <VAR>xcomment</VAR> to the message. Note that when used through a normal
shell command line, the double-quotes around the <VAR>xcomment</VAR> need to be
escaped.
This option has an effect with most languages, namely C, C++, ObjectiveC,
Shell, Python, Lisp, EmacsLisp, librep, Java, C#, awk, Tcl, Perl, PHP,
GCC-source, Glade.
The default keyword specifications, which are always looked for if not
explicitly disabled, are language dependent. They are:

<DT><SAMP>‘--flag=<VAR>word</VAR>:<VAR>arg</VAR>:<VAR>flag</VAR>’</SAMP>
<DD>
<A NAME="IDX185"></A>
Specifies additional flags for strings occurring as part of the <VAR>arg</VAR>th
argument of the function <VAR>word</VAR>. The possible flags are the possible
format string indicators, such as <SAMP>‘c-format’</SAMP>, and their negations,
such as <SAMP>‘no-c-format’</SAMP>, possibly prefixed with <SAMP>‘pass-’</SAMP>.
<BR>
<A NAME="IDX186"></A>
The meaning of <CODE>--flag=<VAR>function</VAR>:<VAR>arg</VAR>:<VAR>lang</VAR>-format</CODE>
is that in language <VAR>lang</VAR>, the specified <VAR>function</VAR> expects as
<VAR>arg</VAR>th argument a format string. (For those of you familiar with
GCC function attributes, <CODE>--flag=<VAR>function</VAR>:<VAR>arg</VAR>:c-format</CODE> is
roughly equivalent to the declaration
<SAMP>‘__attribute__ ((__format__ (__printf__, <VAR>arg</VAR>, ...)))’</SAMP> attached
to <VAR>function</VAR> in a C source file.)
For example, if you use the <SAMP>‘error’</SAMP> function from GNU libc, you can
specify its behaviour through <CODE>--flag=error:3:c-format</CODE>. The effect of
this specification is that <CODE>xgettext</CODE> will mark as format strings all
<CODE>gettext</CODE> invocations that occur as <VAR>arg</VAR>th argument of
<VAR>function</VAR>.
This is useful when such strings contain no format string directives:
together with the checks done by <SAMP>‘msgfmt -c’</SAMP> it will ensure that
translators cannot accidentally use format string directives that would
lead to a crash at runtime.
<BR>
<A NAME="IDX187"></A>
The meaning of <CODE>--flag=<VAR>function</VAR>:<VAR>arg</VAR>:pass-<VAR>lang</VAR>-format</CODE>
is that in language <VAR>lang</VAR>, if the <VAR>function</VAR> call occurs in a
position that must yield a format string, then its <VAR>arg</VAR>th argument
must yield a format string of the same type as well. (If you know GCC
function attributes, the <CODE>--flag=<VAR>function</VAR>:<VAR>arg</VAR>:pass-c-format</CODE>
option is roughly equivalent to the declaration
<SAMP>‘__attribute__ ((__format_arg__ (<VAR>arg</VAR>)))’</SAMP> attached to <VAR>function</VAR>
in a C source file.)
For example, if you use the <SAMP>‘_’</SAMP> shortcut for the <CODE>gettext</CODE> function,
you should use <CODE>--flag=_:1:pass-c-format</CODE>. The effect of this
specification is that <CODE>xgettext</CODE> will propagate a format string
requirement for a <CODE>_("string")</CODE> call to its first argument, the literal
<CODE>"string"</CODE>, and thus mark it as a format string.
This is useful when such strings contain no format string directives:
together with the checks done by <SAMP>‘msgfmt -c’</SAMP> it will ensure that
translators cannot accidentally use format string directives that would
lead to a crash at runtime.

the programmer prescribed it.
By default only the <CODE>c-format</CODE> form is used. The translator should
not have to care about these details.

This implementation of <CODE>xgettext</CODE> is able to process a few awkward
cases, like strings in preprocessor macros, ANSI concatenation of
adjacent strings, and escaped end of lines for continued strings.

Set the copyright holder in the output. <VAR>string</VAR> should be the
copyright holder of the surrounding package. (Note that the msgstr
strings, extracted from the package's sources, belong to the copyright
holder of the package.) Translators are expected to transfer or disclaim
the copyright for their translations, so that package maintainers can
distribute them without legal risk. If <VAR>string</VAR> is empty, the output
files are marked as being in the public domain; in this case, the translators
are expected to disclaim their copyright, again so that package maintainers
can distribute them without legal risk.
The default value for <VAR>string</VAR> is the Free Software Foundation, Inc.,
simply because <CODE>xgettext</CODE> was first used in the GNU project.
<DT><SAMP>‘--foreign-user’</SAMP>

Omit FSF copyright in output. This option is equivalent to

Set the package version in the header of the output. This option has an

<DT><SAMP>‘--msgid-bugs-address=<VAR>email@address</VAR>’</SAMP>
<DD>
<A NAME="IDX222"></A>
Set the reporting address for msgid bugs. This is the email address or URL
to which the translators shall report bugs in the untranslated strings:
<UL>
<LI>Strings which are not entire sentences, see the maintainer guidelines
in section <A HREF="gettext_4.html#SEC19">4.3 Preparing Translatable Strings</A>.
<LI>Strings which use unclear terms or require additional context to be
understood.
<LI>Strings which make invalid assumptions about notation of date, time or
money.
<LI>Pluralisation problems.
<LI>Incorrect English spelling.
<LI>Incorrect formatting.
</UL>
It can be your email address, or a mailing list address where translators
can write to without being subscribed, or the URL of a web page through
which the translators can contact you.
The default value is empty, which means that translators will be clueless!
Don't forget to specify this option.
