python - python gettext - 找不到消息ID时产生错误
问题描述
我正在使用python2.7 gettext。对于翻译,我使用以下代码:
t = gettext.translation(
domain,
path,
fallback=False,
languages=[self._lang, 'en']
)
_ = t.ugettext
translated = _('foo')
默认行为是,如果目录中没有消息 id 的条目,则返回消息 id。
有没有办法产生错误? 一个简单的代码示例将不胜感激。
解决方案
正如Guido Flohr建议的那样,我编写了自己的脚本来检查翻译,但在 python 中使用polib。
翻译文件夹树如下:
locale.json
包含支持的语言列表(这使我可以选择放置草稿语言而不对其进行测试)
{"supported":["en","he"]}
这是 2 个脚本(抱歉缩进不好,我无法让它在 StackOverflow 上工作):
