Eclipse pydev 自动建议在某些情况下不起作用 [英] Eclipse pydev auto-suggestions don't work in some cases

问题描述

我的问题可能很愚蠢，我希望有人成功解决了这个问题.

My question is probably stupid and I hope somebody has succeeded in solving this issue.

有时我无法在自动完成框中看到正确的建议(Eclipse 3.5.2、PyDev 1.5.7).例如:

Sometimes I cannot see right suggestions in auto-completion box (Eclipse 3.5.2, PyDev 1.5.7). For example:

import email
fp = open('my.eml', 'rb')
msg = email.message_from_file(fp)

msg 现在是一个 Message 对象.像 get_payload() 这样的函数工作正常.

msg now is a Message object. And functions like get_payload() works fine.

msg.get_payload()

但我没有在自动完成列表中得到 get_payload().

But I don't get get_payload() in auto-completion list.

我认为 PyDev 不知道 msg 是什么，所以它不知道要显示什么.

I think PyDev has no idea of what msg is, so it doesn't know what to show.

也许我应该导入其他东西，而不仅仅是 email 模块?

Maybe I should import something else, not only email module?

提前致谢！

推荐答案

很有可能，当前的 PyDev 构建还没有达到能够从函数中提取的程度 (message_from_file()在您的情况下)了解它返回什么样的对象以提供自动完成提示.

Chances are, the current PyDev build hasn't gone to a point to be able to extract from a function (message_from_file() in your case) to know what kind of object it returns in order to provide auto-completion hinting.

参见 http://sourceforge.net/projects/pydev/论坛/forum/293649/topic/3697707.

我相信 PyDev 有兴趣支持新的 Python 3 函数语法，PEP 3107，它将解决您的一些问题......在未来.

I believe there is interest in PyDev to support the new Python 3 function syntax, PEP 3107, which will solve some of your problems ... in the future.
