=head1 NAME
|
|
|
|
po4a-translate - convert a PO file back to documentation format
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<po4a-translate> B<-f> I<fmt> B<-m> I<master.doc> B<-p> I<XX.po> B<-l> I<XX.doc>
|
|
|
|
(I<XX.doc> is the output, 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-translate> script is in charge of converting the translation
|
|
(which was done in a PO file) back into the documentation format. The
|
|
provided PO file should be the translation of the POT file which was
|
|
produced by L<po4a-gettextize(1)>.
|
|
|
|
=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<-a>, B<--addendum>
|
|
|
|
Add a file to the resulting file (to put translator's name or a section
|
|
"About this translation", for example). The first line of the file to insert
|
|
should be a PO4A header indicating where it should be added (see section
|
|
B<HOWTO add extra text to translations> in L<po4a(7)>).
|
|
|
|
=item B<-A>, B<--addendum-charset>
|
|
|
|
Charset of the addenda. Note that all the addenda should be in the same
|
|
charset.
|
|
|
|
=item B<-m>, B<--master>
|
|
|
|
File containing the master document to translate.
|
|
|
|
=item B<-M>, B<--master-charset>
|
|
|
|
Charset of the file containing the document to translate.
|
|
|
|
=item B<-l>, B<--localized>
|
|
|
|
File where the localized (translated) document should be written.
|
|
|
|
=item B<-L>, B<--localized-charset>
|
|
|
|
Charset of the file containing the localized document.
|
|
|
|
=item B<-p>, B<--po>
|
|
|
|
File from which the message catalog should be read.
|
|
|
|
=item B<-o>, B<--option>
|
|
|
|
Extra option(s) to pass to the format plugin. 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<-k>, B<--keep>
|
|
|
|
Minimal threshold for translation percentage to keep (i.e. write) the
|
|
resulting file (default: 80). I.e. by default, files have to be translated
|
|
at at least 80% to get written.
|
|
|
|
=item B<-w>, B<--width>
|
|
|
|
Column at which we should wrap the resulting file.
|
|
|
|
=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.

=head1 Adding content (beside translations) to generated files
|
|
|
|
To add some extra content to the generated document beside what you
|
|
translated (like the name of the translator, or a "About this translation"
|
|
section), you should use the B<--addendum> option.
|
|
|
|
The first line of the addendum must be a header indicating where to put
|
|
it in the document (it can be before or after a given part of the
|
|
document). The rest of the file will be added verbatim to the resulting
|
|
file without further processing.
|
|
|
|
Note that if po4a-translate fails to add one of the given files, it discards
|
|
the whole translation (because the missing file could be the one indicating
|
|
the author, what would prevent the users to contact him to report bugs in
|
|
the translation).
|
|
|
|
The header has a pretty rigid syntax. For more information on how to use
|
|
this feature and how it works, please refer to the L<po4a(7)> man page.
