How internationalization is done in MapOSMatic

The web site is translated using Django's internationalization framework. The list of strings to translate is available in this file: django.pot and are edited through maposmatic resource on Transifex.

Add code for your language in: http://git.savannah.gnu.org/cgit/maposmatic/ocitysmap.git/tree/ocitysmap/i18n.py

The three methods to code are:

• language_code(): returns the language code of the specific language supported, e.g. fr_FR.UTF-8;
• user_readable_street(name): transforms a street name into a suitable form for the map index, e.g. Paris (Rue de) for French;
• first_letter_equal(a, b): returns True if the letters a and b are equal in the map index;
• isrtl(): returns True if the language is written Right to Left (RTL).

Then add a construction of this object in the hash-table language_map at the end of i18n.py.

To add a new language for a map index in maposmatic, one should:

1. Add the new language code and the way it will be displayed on the main page in www/settings.py: http://git.savannah.gnu.org/cgit/maposmatic.git/tree/www/settings.py#n111
2. Check that this language code is supported by ocitysmap (otherwise add it, see above): http://git.savannah.gnu.org/cgit/maposmatic/ocitysmap.git/tree/ocitysmap/i18n.py#n742

You shoud recompile .po files for ocitysmap (see I18N doc file) and maposmatic.

You should configure needed locales on your maposmatic server.

• On Debian: dpkg-reconfigure locales
• On Ubuntu: https://answers.launchpad.net/ubuntu/+question/3707
  1. Check which locales are supported:

     less /usr/share/i18n/SUPPORTED

  2. Add the locales you want (for example fr) :

     locale-gen fr_FR.UTF-8
     locale-gen fr_FR
     locale-gen fr_FR@euro

• Here is what has been done on the main server:

  for code in en es fr de it ar ru nb sl sv et da cs ca hr sk fi el hu is lt pl ro tr eo ; do
    locale-gen --lang $code
  done
  locale-gen fr_FR@euro
  locale-gen fr_BE@euro
  locale-gen fr_LU@euro
