如何要求对象以字符串形式返回其类和方法源？

Question

I want to find the source of a Class and its methods (including all variables too, local , instance, class , class instance etc) and return them as a string or a collection of strings.

I have found MethodNode>>sourceText and CompiledMethod>>sourceCode but I have no clue how to send these messages or if they are the messages I am looking for.

Also any pointers as to how to navigate the Pharo syntax by code using something like AST would be greatly appreciated.

Answer 1

First ask the class of your object, then ask, for example, all the methods defined in this class and then collect the source-code of each method:

'Pharo' class methods collect: [ :each | each sourceCode ]

You can find the relevant methods for other properties of your class in the accessing protocols of Behavior , a superclass of Class .

Answer 2

In addition to the answer of Martin there are also other ways of doing this for example

(Object compiledMethodAt: #printString) sourceCode

will return the source code for a specific method.

In case we want to navigate through the syntax using AST of a method:

( Object compiledMethodAt: #halt ) ast nodesDo:[ :node |  node inspect].

Take a look at RBProgramNode and its relevant subclasses to have taste what is possible for navigating and processing source code.

并且，根据您的确切需求，您应该注意特征，扩展方法和超类中定义的方法。
