INTERNATIONALIZATION
Mailman 2.1 is multilingual. By default it supports English, but
additional languages may also be available. If the language you
want to add is already supported by Mailman, then getting all your
lists to also support that language is fairly easy. You just need
to go to the administrative web pages, click on the "Languages"
category, and select the languages you want your list to support.
If the language you want to use has not been previously
translated, or you don't know where to find the language pack for
your language, read the section below or contact the Mailman
internationalization mailing list mailman-i18n@python.org.
ADDING NEW TRANSLATIONS
Suppose you want to add new translations for a previously
unsupported language, what steps would you need to take?
First, you should send a message to mailman-i18n@python.org to
make sure nobody has already created the translations for your
language. In the example below, we're going to create a
translation for the mythical language "Fredonia" which has the
official language code of "xx".
You should see
http://www.list.org/i18n.html
for more information on internationalizing Mailman. Also, Simone
Piunno -- who is the Italian translation champion -- has written
up some nice instructions, which are provided below.
In general you need to do two things to add translations for a
language in Mailman. You need to translate the message catalog
and you need to translate the templates.
To translate the message catalog, grab the file
messages/mailman.pot and make a copy called mailman.po in the
subdirectory messages/xx/LC_MESSAGES. Then you edit the file and
add the translations for each message identified in the catalog.
It will be very helpful to have a good tool, such as KDE's KBabel
tool, or po-mode for Emacs, for this part of the job.
Once you've added your translations, you can then run msgfmt over
your .po file to generate messages/xx/LC_MESSAGE/mailman.mo. Run
"make" in the messages subdirectory to do this.
Next, create the subdirectory templates/xx and translate each of
the files in templates/en/*.{html,txt}. These you should also
donate back to the Mailman project.
To make Mailman and your lists aware of the new language, follow
the directions in the section above.
TRANSLATION HINTS
Q: If your language uses non-ASCII characters, such as the cedilla in
French, how should you add these to the catalogs and templates?
A: For any message that is destined for the web interface, use an
HTML entity reference where appropriate. For messages destined
for email, you should use the non-ASCII characters explicitly.
This includes both for the message catalog and the templates.
RESYNCHRONIZING THE CATALOG
As Mailman development continues, new updated catalogs
(i.e. mailman.pot files) will be made available. As mailman.pot
changes, the individual language catalogs
(i.e. xx/LC_MESSAGES/mailman.po files) need to be updated as well.
In general, I as the Mailman maintainer will merge the new
catalogs with the individual language catalogs, and commit the
updates to CVS. Translators should grab the new mailman.po files
from CVS and update the translated messages. They should also
update the template translations.
For best results, you will probably want to keep current on
changes to Mailman 2.1 in the CVS. As Mailman 2.1 moves towards
final release, the catalogs and templates should start to
stabilize. Alternatively, occasionally I will make new English
language packs available on SourceForge, and you can use these to
create your translations.
DONATING YOUR TRANSLATION BACK TO MAILMAN
We'd really appreciate it if you donate your translations back to
the Mailman project, so that others can benefit from your effort.
You'll get credit of course, in the Mailman documentation. Here
are the steps to donate your translations, either the first time
or subsequent updates.
The best thing to do is to send me <barry@python.org> a "tarball",
i.e. a gzip'd tarfile, that can be unpacked in the top level
directory of the Mailman CVS tree. This would be the directory
containing this README-I18N.en file.
Your tarball should contain two directories, where your donated
language is `xx':
templates/xx
messages/xx
In templates/xx there should be the translated templates, all the
.txt and .html files, for your language, mirroring those in the
English template directory (always the master copy).
In messages/xx you should have a single directory LC_MESSAGES, and
in that directory a file called mailman.po, which is the human
readable catalog for your language. Do not send me the mailman.mo
file, since I'll recreate it on my end, and that'll save on the
size of the tarball.
That's basically it. If you need to include a README, please call
it README.xx and put it in the messages/xx directory. README.xx
can be in your native language.
You can email the tarball to me, and if this is the first
installation of the language, please tell me what the
add_language() call in Defaults.py.in should be for your
language.

MORE INSTRUCTIONS
Here is the recipe that Simone Piunno used for the Italian
translations:
"You can start without much technical knowledge, but if you want
to keep your translation up-to-date (while the development branch
evolves into the next stable release) you'd better learn how to
use cvs and diff.
Here is my recipe.
Basically, you'll start by copying templates/en/* to your sandbox dir
and then translating each file. Keep in mind that %(foo)s is a
variable reference (much like %s in C) and must be left untouched.
Also, you must be able to recognize a markup tag (eg, <foo>) because
they must be left untouched too, and you should know how to escape
non-ASCII characters, e.g. "�" -> "è", but only in html files.
Remember that if you need a literal % sign, it must be doubled: %%
Next, you copy messages/mailman.pot, renaming it to serbian.po.
You can open this file with kbabel (a tool included in KDE SDK) and
translate each string (original on the higher half of the window, your
translation on the bottom half).
If you are a masochist, you can even use emacs PO mode ;)
Keep attention to the same markers and escaping as above, with the added
complexity that here it's harder to say when a string is html (e.g. used
for web UI) or pure text (e.g used for email interface)
Then you try to compile you .po file:
msgfmt -v -o serbian.mo serbian.po
No error messages should appear.
Next, copy your files on an installed mailman tree, and run
bin/transcheck XX, where XX is your country code.
No warning should appear (but maybe some warning is ok, if you really
know what you're doing).
Now, try to run your translation (add an "add_language" line to
Mailman/Defaults.py) and check the many scattered pieces blend
together well. Sometimes you'll need some adjustment.
When you're satistied, pack up a tar.gz with the following structure:
messages/XX/LC_MESSAGES/mailman.po
templates/XX/admindbdetails.html
templates/XX/admindbpreamble.html
.
.
templates/XX/userpass.txt
templates/XX/verify.txt
(XX is your country code) and send it to Barry Warsaw. Do not
include the mailman.mo file if you can help it.
By that time, your translation could be somewhat obsolete, because
templates and mailman.pot could have been evolved meanwhile.
Don't panic.
You'll need to check diffs to find what changed and how, so that
you can easily update your files.
Save everything everytime, you'll need it.
