问题描述
django-admin.py makemessages 在包装真长字符串的情况下会出现错误warning：unterminated string：
django-admin.py makemessages dies with errors "warning: unterminated string" on cases where really long strings are wrapped:
string = "some text \
more text\
and even more"
这些字符串甚至不需要翻译 - 例如sql查询字符串。
当我连接字符串时，问题消失了，但结果看起来很丑，需要时间才能加入...
These strings don't even need to be translated - e.g. sql query strings.The problem goes away when I concatenate the string, but the result looks ugly and it takes time to join them...
有没有人有问题这个？你有没有找到一种解决方法？
Does anyone have a problem like this? Have you found a way to fix it?
我有以下版本的工具：
xgettext -0.17，gettext-0.17，django-1.0.2，python-2.6.2
xgettext-0.17, gettext-0.17, django-1.0.2, python-2.6.2
有一个在这个问题上，但它被关闭可能是因为错误只出现在组件版本的某些组合。
There was a ticket on this issue, but it was closed probably because the error appears only in some combination of component versions.
编辑：发现问题的根源 - xgettext向sterr打印警告消息，django将其作为致命错误并退出。
found the source of problem - xgettext prints warning messages to sterr and django takes them as fatal errors and quits.
xgettext调用是0 - 成功。我猜，django应该认识到它是成功的，而不是因为警告而退出。
return status of xgettext call is 0 - "success". I guess that django should recognize it as success and not quit because of warnings.
有趣的是，如果需要翻译，xgettext仍然会提取反斜杠包装的字符串，但会发出警告stderr（unterminated string）和.po文件（国际化消息不应包含`\r'转义序列）
Interestinly xgettext still extracts backslash-wrapped strings if they need to be translated, but gives warnings in stderr ("unterminated string") and .po file ("internationalized messages should not contain the `\r' escape sequence")
xgettext调用如下：
xgettext call is the following:
xgettext -d django -L Python --keyword=gettext_noop \
--keyword=gettext_lazy --keyword=ngettext_lazy:1,2 \
--keyword=ugettext_noop --keyword=ugettext_lazy \
--keyword=ungettext_lazy:1,2
--from-code UTF-8 -o - source_file.py
从django调用/core/management/commands/makemessages.py
called from django/core/management/commands/makemessages.py
推荐答案
我可以想到两种可能性：你可能会有更多的空间行尾的反斜线;或者您可能会以某种方式结束您的源代码中的错误的行尾字符（例如，当您的Python期待Unix样式时，Windows风格，从而禁用反斜杠）。
I can think of two possibilities: you might have an extra space after your backslash at the end of the line; or you might be somehow ending up with the wrong line-ending characters in your source (e.g. Windows-style when your Python is expecting Unix-style, thus disabling the backslashes).
无论如何，我将利用C风格的自动字符串连接：
Either way, I would take advantage of C-style automatic string concatenation:
>>> string = ("some text "
... "more text "
... "and even more")
>>> string
'some text more text and even more'
或者，如果你不使用多行字符串：
Alternatively, if you don't mind newlines ending up in there, use multi-line strings:
>>> string = """some text
... more text
... and even more"""
IMO这些看起来更好，在重构时更不脆弱。
IMO these look much nicer, and are much less fragile when refactoring.
这是否有帮助？
