获取函数的AST [英] Getting the AST of a function

问题描述

说我有一个功能:

function hi()
    print('hi')
end

我希望能够将此函数作为参数并对其进行分析，例如列出其中的所有函数调用，查看其引用的所有变量等.

I'd like to be able to take this function as an argument and perform analysis on it, such as listing all the function calls in it, seeing all the variables it references, etc.

请注意，我并不是在谈论分析源代码；我没有函数的源文本，只有函数对象，即在运行时完成.

Note that I'm not talking about analysing source code; I don't have the source text of the function, I just have the function object, i.e. this is being done at runtime.

我认为您要执行此操作的方法是获取该功能的AST.但是我不知道该怎么做.那么我将如何获取函数的AST(或者，如果有更好的方法，还要对其进行分析)?

The way I think you'd go about doing this is to get the AST of the function. But I don't know how to do that. So how would I go about getting the AST of a function (or otherwise analysing it if there's a better way)?
