7f029a23 1How to translate SquirrelMail into another language?
4This document does not deal with CVS and how to upload translations to
5the repository.
71. First time translation
10a) You must have gettext installed. If it is not installed you can
47c5f7fc 11 download the sources from
7f029a23 12 <URL:ftp://ftp.gnu.org/pub/gnu/gettext/>.
14b) Find the language code for the language you are going to translate
15 into. A list of language codes can be found at
e47c673b 16 <URL:http://lcweb.loc.gov/standards/iso639-2/langhome.html>. If
974dd86d 17 there is a 2 letter code for the language, use this.
7f029a23 18
19 Create a directory squirrelmail/locale/language_code/LC_MESSAGES/.
2ce19283 20 Copy squirrelmail/po/squirrelmail.pot into this directory and rename
21 it to squirrelmail.po. This is the file that is going to be translated.
7f029a23 22
1e63b430 23c) To translate the actual strings fill in the msgstr after each
47c5f7fc 24 msgid with the appropriate translation. There are a few tools which
1e63b430 25 can make this job a bit easier at
2ce19283 26 <URL:http://i18n.kde.org/translation-howto/specialized-programs.html#gui-tools>.
7f029a23 27
28 Convert the translated squirrelmail.po into a binary file by
29 running the command "msgfmt -o squirrelmail.mo squirrelmail.po" in
30 the directory where the translated squirrelmail.po is residing.
32d) Add the language name and language code to the array at the top of
219c74f8 33 squirrelmail/functions/i18n.php.
7f029a23 34
e3c6f613 35There is also a small script in the po/ directory that can help in
36creating charset mappings from the mappings files that are provided by
37the Unicode consortium.
7f029a23 38
392. Maintaining translations
1e63b430 42The text strings in the program will change over time. This means that
43strings that are already translated are no longer used and new strings
44are added. Therefore it is necessary to maintain the translations.
7f029a23 45
46a) There should always be an updated template containing all strings
2ce19283 47 in SquirrelMail in squirrelmail/po/squirrelmail.pot. To merge all new
7f029a23 48 strings in this file into an existing translation run the command
50msgmerge squirrelmail/locale/language/LC_MESSAGES/squirrelmail.po \
2ce19283 51squirrelmail/po/squirrelmail.pot > \
0a52832c 52squirrelmail/locale/language/LC_MESSAGES/squirrelmail.po.new
7f029a23 53
54 This should keep all strings that are unchanged and comment out all
55 strings that are no longer in use. You might want to make a copy
56 before doing this.
2ce19283 58SquirrelMail contains po/mergepo script that can merge strings without need
59to write that complex msgmerge command. Just put your translation name as
47c5f7fc 62b) Run msgfmt again to create a new binary file.
7f029a23 63
653. Updating the template
2ce19283 68SquirrelMail provides po/xgetpo script that extracts all the required
69strings and updates po/squirrelmail.pot file.
