debconf-gettextize - extract translations of debconf templates into PO files
] [ --choices
files read by debconf contain English
text and translations in the same file. But in source packages, translations
are managed in separate files to help translators. In the initial
implementation, a master templates
file contained only English text,
files contained both original and
translated strings for the language xx
program was merging master and translated
The new implementation with "po-debconf" is based on
"gettext". Maintainers mark translatable fields by prepending them
with an underscore, English strings are automatically extracted into a POT
file, translators work on normal PO files, and po2debconf
merged templates file with the same structure.
program was initially designed to help migrating
to the new implementation.
- It reads a list of master files and their associated
translations, and generates po/*.po files for each language
containing translated strings.
- Each input file receives an ".old" suffix, and a
new master file overwrites the old one; it is identical to the previous
master file except that an underscore is prepended to translatable fields.
Developers can then choose which fields translators have to work on and
which ones are skipped because their values are not locale-dependent.
- A po/POTFILES.in file is also created, it contains
the list of templates files debconf-updatepo has to
Typically the debconf-gettextize
program must be run only once when
transforming from the first implementation to the "po-debconf"
format, but it can also be used afterwards to transform a "_Choices"
field into "__Choices" (or vice-versa) without losing translations,
when using the "--merge" flag (alongside with "--choices"
or not). The desired template containing the "_Choices" or
"__Choices" fields to modify has to be copied into a temporary
template file, which is passed to debconf-gettextize
as an argument.
Then the following steps are performed:
- po2debconf is run on this template file to generate
a translated templates file.
- This translated templates file is processed as described
above and PO files are generated.
- Newly created PO files are merged with existing ones.
When PO files are merged, "_Choices" fields have to be replaced by
"__Choices" (or vice-versa) in the original templates file before
, otherwise new translations will be fuzzy.
- -h, --help
- Display a usage summary for the program and exit.
- -v, --verbose
- Process in verbose mode.
- Set directory for PO files. Default is to search for PO
files in the po subdirectory below the location of the first master
- By default, debconf-gettextize replaces
"Choices" fields by "_Choices". With this flag,
"__Choices" fields are written instead.
- When this flag is set, the strings are merged with existing
PO files. The templates files and po/POTFILES.in are not
The "Default" field is special when template type is
"Select" or "Multiselect", because a value has to be
chosen amongst the English
list of choices, even for localized values.
Normally this field must not be changed, but in rare circumstances localized
values are meaningful (e.g. to choose the default language of an application).
In order to let translators know that this localized "Default" field
is special, you must by convention call it "_DefaultChoice" instead
