无论定义何种类，都跳转到方法定义 [英] Jump to method definition regardless of class it is defined in

问题描述

在MatlabⓇIDE中，有没有简单的方法可以跳转到特定方法的定义，而不知道它定义在哪个类中？

In the MatlabⓇ IDE, is there any easy way to jump to the definition of a particular method, without knowing in what class it is defined?

对于自我包含函数，我可以输入编辑funcname.m 。课程也一样。但是，特定类的超类层次结构可能很大。通过使用元类，我可以找到在哪个类中定义方法，然后打开该类，并浏览到适当的定义。这比自包含功能要多得多。

For self-contained functions, I can type edit funcname.m. The same for classes. However, the hierarchy of superclasses for a particular class may be large. By using metaclasses, I can find out in what class a method was defined, then open the class, and browse to the appropiate definition. This is a lot more work than it is for self-contained functions.

从交互式提示中，是否有任何直接方式到 跳转到特定方法的定义，或在此方法中放置断点（以便执行它会导致编辑器跳转到定义）？

From the interactive prompt, is there any direct way to either jump to the definition of a particular method, or put a breakpoint in this method (so that executing it will cause the editor to jump to the definition)?

推荐答案

您可以使用哪个在给定特定输入参数时找到函数。

You can use which to locate a function when given specific input arguments.

比如我们在路径上有以下文件：

Say for example we have the following files on the path:

>> which -all fun
C:\Users\Amro\Desktop\fun.m
C:\Users\Amro\Desktop\Klass.m    % Klass method

Klass.m

Klass.m

classdef Klass < handle
    methods
        function fun(obj)
            disp('hello from Klass')
        end
    end
end

fun.m

fun.m

function fun()
    disp('hello from fun')
end

现在我们可以区分两者给出的参数：

Now we can differentiate between the two given what arguments they take:

>> o = Klass();
>> which('fun(o)')
C:\Users\Amro\Desktop\Klass.m  % Klass method

>> which('fun')
C:\Users\Amro\Desktop\fun.m

请注意，在类方法的情况下，我们必须使用以下语法： fun（obj，args，...）而不是 obj.fun（args，...）

Note that in the class method case, we have to use the syntax: fun(obj, args, ...) as opposed to obj.fun(args, ...)

您可以使用 matlab.desktop.editor API：

matlab.desktop.editor.openAndGoToFunction(which('Klass'),'fun');
