mw-aiohttp-babel 0.1.8

变更：

1，增加类似flask_babel的Babel类 2，_() 直接调用 babel.support.Translations.translation,原来的_()改为了lazy_gettext()

Babel使用样例：

import aiohttp_jinja2
from mw_aiohttp.web import Application
from mw_aiohttp_babel import Babel,_

babel = Babel(directory='/path/to/locales', domain='messages',default_locale='en_US')

# you can use your own locale detection method, if necessary.
# aiohttp_babel checks cookie parameter `locale` or `Accept-Language`
# header by default.
# def detector(request):
#     if request.url.host == 'es.example.com':
#         return 'es'
#     elif request.url.host == 'zh.example.com':
#         return 'zh'
#     else:
#         return 'en'
# set_locale_detector(detector)

jinja_loader = jinja2.FileSystemLoader('./templates')
app = Application()
babel.init_app(app)
aiohttp_jinja2.setup(app, loader=jinja_loader)
jinja_env = aiohttp_jinja2.get_env(app)
jinja_env.globals['_'] = _

保留aiohttp_babel的样例：

import aiohttp_jinja2
from mw_aiohttp.web import Application
from mw_aiohttp_babel.locale import (load_gettext_translations,
                                  set_default_locale,
                                  set_locale_detector)
from mw_aiohttp_babel.middlewares import babel_middleware, lazy_gettext as _


set_default_locale('en_GB')  # set default locale, if necessary
# load compiled locales
load_gettext_translations('/path/to/locales', 'domain')

# you can use your own locale detection method, if necessary.
# aiohttp_babel checks cookie parameter `locale` or `Accept-Language`
# header by default.
def detector(request):
    if request.url.host == 'es.example.com':
        return 'es'
    elif request.url.host == 'zh.example.com':
        return 'zh'
    else:
        return 'en'
set_locale_detector(detector)

jinja_loader = jinja2.FileSystemLoader('./templates')
app = Application(middlewares=[babel_middleware])

aiohttp_jinja2.setup(app, loader=jinja_loader)
jinja_env = aiohttp_jinja2.get_env(app)
jinja_env.globals['_'] = _

创建多语言文件 :

1. 创建pot模板

   $ pybabel extract -F babel.cfg -o messages.pot app

2. 创建多语言的po文件

   > 简体中文

   $ pybabel init -i messages.pot -d app/translations -l zh_CN

   > 繁体中文

   $ pybabel init -i messages.pot -d app/translations -l zh_TW

   > 英文

   $ pybabel init -i messages.pot -d app/translations -l en

3. 更新多语言的po文件

   $ pybabel update -i messages.pot -d app/translations

4. 产生mo文件

   $ pybabel compile -d app/translations
