使用 Eclipse 自动补全 + PyDev 用于函数参数

发布于 2024-09-07 13:31:16 字数 548 浏览 3 评论 0原文

我在 Windows XP 计算机上使用 Eclipse 和 PyDev 以及 Iron Python。我有一个类定义，它接受一个对象作为参数，它本身就是另一个类的实例化，如下所示：

myObject1 = MyClass1()
myObject2 = MyClass2(myObject1)

这两个类定义位于不同的模块 myclass1.py 和 myclass2.py 中，我希望我能够自动完成工作当在 myclass2 中使用 myObject1 时。换句话说，在文件 myclass2.py 中我可能有这样的内容：

""" myclass2.py """
class MyClass2():
    def __init__(self, myObject1):
        self.myObject1 = myObject1
        self.myObject1.  <============== would like auto code completion here

是否有可能使其工作？

谢谢！

I am using Eclipse and PyDev with Iron Python on a Windows XP machine. I have a class definition that takes an object as an argument which is itself an instantiation of another class like this:

myObject1 = MyClass1()
myObject2 = MyClass2(myObject1)

The two class definitions are in different modules, myclass1.py and myclass2.py and I was hoping I could get auto completion to work on myObject1 when it is being used in myclass2. In other words, in the file myclass2.py I might have something like this:

""" myclass2.py """
class MyClass2():
    def __init__(self, myObject1):
        self.myObject1 = myObject1
        self.myObject1.  <============== would like auto code completion here

Is it possible to make this work?

Thanks!

在 PyDev/Eclipse 中使用 Jython，我也想知道这个问题。代码完成应该适用于您在 MyClass2 中其他地方使用过的 MyClass1 方法，但不适用于整个 API。我认为这是因为您可以动态添加和删除类中的方法，因此 Eclipse 无法保证任何特定方法存在，或者方法列表是完整的。

例如：

>>> class a:
...     def b(self):
...         print('b')
...
>>> anA = a()
>>> anA.b()
b
>>> del a.b
>>> anA.b()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: a instance has no attribute 'b'

因此，如果代码完成在这里向您显示方法 b()，那么它将是不正确的。

同样，

>>> class a:
...     pass
...
>>> anA = a()
>>> anA.b()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: a instance has no attribute 'b'
>>> def b(self):
...     print('b')
...
>>> a.b = b
>>> anA.b()
b

未显示方法 b() 的代码完成将是不正确的。

我可能是错的，但我认为这是一个可靠的猜测。 :)

Using Jython in PyDev/Eclipse, I've wondered about this too. Code completion should work for MyClass1 methods you've used somewhere else in MyClass2, but not for the entire API. I think it's because you can add and remove methods from a class on the fly, so Eclipse can't guarantee that any particular method exists, or that a list of methods is complete.

For example:

>>> class a:
...     def b(self):
...         print('b')
...
>>> anA = a()
>>> anA.b()
b
>>> del a.b
>>> anA.b()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: a instance has no attribute 'b'

So if code completion showed you the method b() here, it would be incorrect.

Similarly,

>>> class a:
...     pass
...
>>> anA = a()
>>> anA.b()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: a instance has no attribute 'b'
>>> def b(self):
...     print('b')
...
>>> a.b = b
>>> anA.b()
b

So code completion that didn't show the method b() would be incorrect.

I could be wrong, but I think it's a solid guess. :)

使用垃圾邮件行（if False ...）创建对象，我的 Pydev 2.5 没问题。

""" myclass2.py """
    class MyClass2():
    def __init__(self, myObject1):
        if False : myObject1 = MyClass1()
        self.myObject1 = myObject1        
        self.myObject1.  <============== would like auto code completion here

With a spam line (if False ...) with creating object, it's OK with my Pydev 2.5.

""" myclass2.py """
    class MyClass2():
    def __init__(self, myObject1):
        if False : myObject1 = MyClass1()
        self.myObject1 = myObject1        
        self.myObject1.  <============== would like auto code completion here
