2. about me @rvarshney on the web
4. most common tools are gettext and babel ! import gettext as _ print _("Translate me.") ! from babel import dates, numbers dates.format_datetime(date, locale='de') numbers.format_decimal(1.234, locale='de') ! ! basics
5. ! # Extraction config file (babel.cfg) [python: **.py] [jinja2: **.html] [javascript: **.js] ! [extractors] python = babel.messages.extract:extract_python jinja2 = jinja2.ext:babel_extract javascript = babel.messages.extract:extract_javascript ! ! basics
6. # Run extraction $ pybabel extract --mapping-file babel.cfg --output out.po <source_dir> ! ! ! ! ! basics
7. ! # Translations for MYAPP. # Copyright (c) 2014 ORGANIZATION ! #: app/views.py:20 #, python-format msgid "Translate me." msgstr "" ! ! basics

10. latency
11. ! def greeting(name, is_welcome): if is_welcome: return _("Hey there!") else: return _("Bye Bye") ! ! ! strings before logic
12. ! class Greetings(object): WELCOME_MESSAGE = _("Hey there!") BYE_MESSAGE = _("Bye!") ! ! def greeting(name, is_welcome): if is_welcome: return Greetings.WELCOME_MESSAGE else: return Greetings.BYE_MESSAGE strings before logic
13. ! class Greetings(object): WELCOME_MESSAGE = _("Hey there!”) BYE_MESSAGE = _("Bye!") BYE_MESSAGE = _("See you later!") ! ! ! ! ! lost in translation
14. ! #, python-format msgid "Bye!" msgstr "Au revoir!" ! #, python-format msgid "See you later!" msgstr "" ! lost in translation

18. babel gotchas #: app/views.py:20 #, python-format #, fuzzy msgid "Translate them." msgstr "Traduisez-moi"
19. babel gotchas “strings might be marked as fuzzy — if you have fuzzy entries, make sure to check them by hand and remove the fuzzy flag before compiling.”
