Hey re, fellow Go programmer! If you're reading this, you're probably stuck in a jungle of ASTs and types, trying to figure out how to get real type of an identifier from an Abstract Syntax Tree . Well, hold on to your hat, because I'm about to introduce you to magical world of go/types. But first, let's dive into some unorganized thoughts and random facts about Go and ASTs.

Understanding Problem: Types in ASTs

When you're working with AST in Go, you'll notice that it's like a puzzle with missing pieces. The AST is like a map of your code, showing where each identifier is, but it doesn't tell you what type it is. That's because types are like secret sauce that makes your code work, and AST is just raw ingredients.，我坚信...

For example, imagine you have a variable called "textToContain" that you've declared like this:，啊这...

textToContain := text := 

Now, you can see that "textToContain" is a pointer to something, but what is it pointing to? The AST doesn 坦白说... 't say. It's like looking at a recipe and seeing "mix ingredients" but not knowing what ingredients are.

Introducing go/types: The Magic Pill

平心而论... So, what's magic pill that will make your life easier? It's called go/types. This package is like a wizard that can read your code's mind and tell you real types of identifiers. But wait, re's more! go/types is also part of go/loader package, which is like wizard's apprentice that helps load your code into magic realm of types.

调整一下。 But hold on, don't go running to your terminal just yet. Let's first understand how to use se packages to get real type of an identifier.

Example: A Super Simple Static Analysis

Alright, let's put on our wizard hats and create a super simple static analysis example. We'll parse a file, extract a method call's receiver identifier, and n use go/types to find out what type it really is.，太治愈了。

Here's a snippet of code that's supposed to be helpful:

import (
        "fmt"
        "go/types"
        "golang.org/x/tools/go/loader"
        "golang.org/x/tools/go/packages"
    )
    func main {
        pkgs, err := packages.Load
        if err != nil {
            panic
        }
        pkg, err := loader.Load
        if err != nil {
            panic
        }
        // Find  type of  identifier "textToContain"
        obj := pkg.Scope.Lookup
        if obj == nil {
            panic
        }
        typ := obj.Type
        fmt.Printf
    }

Now, this code is like a recipe with all ingredients listed, but no instructions on how to use m. It's supposed to be helpful, but it's not. You need to know what each part does, and that's where real challenge begins.

Conclusion: The Real Type of Identifiers

In conclusion, getting real type of an identifier in an AST using go/types is like trying to solve a Rubik's Cube while blindfolded. It's possible, but it's not easy. The go/types package is like a flashlight in dark, but you still need to know how to use it.，开倒车。

So, if you're ready to become a wizard in world of Go and ASTs, go/types is your magic wand. Just remember, i 躺平。 t's not a silver bullet; it's a tool that requires some serious practice and understanding of Go's type system.

And remember, if you ever get stuck, just keep staring at your screen and typing random characters. Sometimes, that's only way to make progress in this wild and wacky world of programming.，扯后腿。
