=head1 NAME
|
|
|
|
po4a-updatepo - update the translation (in PO format) of documentation
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<po4a-updatepo> B<-f> I<fmt> (B<-m> I<master.docE>)+ (B<-p> I<XX.po>)+
|
|
|
|
(I<XX.po> are the outputs, all others are inputs)
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The po4a (PO for anything) project goal is to ease translations (and more
|
|
interestingly, the maintenance of translations) using gettext tools on
|
|
areas where they were not expected like documentation.
|
|
|
|
The B<po4a-updatepo> script is in charge of updating PO files to make
|
|
them reflect the changes made to the original documentation file. For that,
|
|
it converts the documentation file to a POT file, and call L<msgmerge(1)>
|
|
on this new POT and on the provided PO files.
|
|
|
|
It is possible to give more than one PO file (if you want to update several
|
|
languages at once), and several documentation files (if you want to store
|
|
the translations of several documents in the same PO file).
|
|
|
|
If the master document has non-ASCII characters, it will convert the PO files
|
|
to UTF-8 (if they weren't already), in order to allow non-standard characters
|
|
in a culture independent way.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-f>, B<--format>
|
|
|
|
Format of the documentation you want to handle. Use the B<--help-format>
|
|
option to see the list of available formats.
|
|
|
|
=item B<-m>, B<--master>
|
|
|
|
File(s) containing the master document to translate.
|
|
|
|
=item B<-M>, B<--master-charset>
|
|
|
|
Charset of the files containing the document to translate. Note that all
|
|
files must have the same charset.
|
|
|
|
=item B<-p>, B<--po>
|
|
|
|
PO file(s) to update. If these files do not exist, they are created by
|
|
B<po4a-updatepo>.
|
|
|
|
=item B<-o>, B<--option>
|
|
|
|
Extra option(s) to pass to the format plugin and other po4a internal module.
|
|
Specify each option in the 'I<name>B<=>I<value>' format. See the documentation of
|
|
each plugin for more information about the valid options and their meanings.
|
|
|
|
=item B<--no-previous>
|
|
|
|
This option removes B<--previous> from the options passed to B<msgmerge>.
|
|
This permits to support versions of B<gettext> earlier than 0.16.
|
|
|
|
=item B<--previous>
|
|
|
|
This option adds B<--previous> to the options passed to B<msgmerge>.
|
|
It requires B<gettext> 0.16 or later, and is activated by default.
|
|
|
|
=item B<--msgmerge-opt> I<options>
|
|
|
|
Extra options for B<msgmerge>.
|
|
|
|
=item B<-h>, B<--help>
|
|
|
|
Show a short help message.
|
|
|
|
=item B<--help-format>
|
|
|
|
List the documentation formats understood by po4a.
|
|
|
|
=item B<-V>, B<--version>
|
|
|
|
Display the version of the script and exit.
|
|
|
|
=item B<-v>, B<--verbose>
|
|
|
|
Increase the verbosity of the program.
|
|
|
|
=item B<-d>, B<--debug>
|
|
|
|
Output some debugging information.
|
|
|
|
=item B<porefs> I<type>[,B<wrap>|B<nowrap>]
|
|
|
|
Specify the reference format. Argument I<type> can be one of B<none> to not
|
|
produce any reference, B<noline> to not specify the line number (more
|
|
accurately all line numbers are replaced by 1), B<counter> to replace line
|
|
number by an increasing counter, and B<full> to include complete
|
|
references.
|
|
|
|
Argument can be followed by a comma and either B<wrap> or B<nowrap> keyword.
|
|
References are written by default on a single line. The B<wrap> option wraps
|
|
references on several lines, to mimic B<gettext> tools (B<xgettext> and
|
|
B<msgmerge>). This option will become the default in a future release, because
|
|
it is more sensible. The B<nowrap> option is available so that users who want
|
|
to keep the old behavior can do so.
|
|
|
|
=item B<--msgid-bugs-address> I<email@address>
|
|
|
|
Set the report address for msgid bugs. By default, the created POT files
|
|
have no Report-Msgid-Bugs-To fields.
|
|
|
|
=item B<--copyright-holder> I<string>
|
|
|
|
Set the copyright holder in the POT header. The default value is
|
|
"Free Software Foundation, Inc."
|
|
|
|
=item B<--package-name> I<string>
|
|
|
|
Set the package name for the POT header. The default is "PACKAGE".
|
|
|
|
=item B<--package-version> I<string>
|
|
|
|
Set the package version for the POT header. The default is "VERSION".
