00001 '''
Provides support for internationalization using the Python gettext
module. Configures gettext to use the translation associated with the locale
set by the user's environment at runtime. If no appropriate translation is 
found, the default language is used: the one in which the strings in the
code are written (i.e. English).

The gettext function in the gettext module is alised as _ to match the name of 
the equivalent C function provided by GNU gettext tools.

See the Python documentation on the gettext module at 
U{http://docs.python.org/lib/module-gettext.html}. A brief tutorial on 
i18n and Python is available at

00028 def bind(domain, locale_dir):
  Convenience function for creating a new instance of a Python translation 
  class bound to a domain and locale directory other than the default one for
  LSR. This function is useful in L{UIElement}s which have translatable strings
  and ship separately from LSR with their own translation files. For instance,
  a L{Perk} writer may call this function globally in his L{Perk} and assign
  the result to a global variable _ to use the GNU translation system without
  affecting how other components of LSR are translated.
  @param domain: Filename of the translation file, typically the name of the
    project with which it is associated
  @type domain: string
  @param locale_dir: Directory to search for translation files for the domain
  @type locale_dir: string
  @return: Bound method ugettext on the translation object
  @rtype: callable
  gtk.glade.bindtextdomain(domain, locale_dir)
    t = gettext.translation(domain, locale_dir)
    return t.ugettext
  except IOError:
    # no translation file, so just return the unicode version of the given 
    # string
    return lambda x: unicode(x)

# use the current system locale
locale.setlocale(locale.LC_ALL, '')
# build the path to where the main translation file lives
LOCALE_DIR = os.path.join(sys.prefix, 'share', 'locale')
DOMAIN = 'accerciser'
# build a default instance to the LSR domain and locale directory
# allow gettext to extract the string, but it should not be translated inline.
