1、基础了解

const {parse} =require("@babel/parser");

const generator = require("@babel/generator").default

const ast_code = parse('var a;a = "yuanrenxue"')

console.log(ast_code)

ast_code.program.body[0].declarations[0].id.name = "b"

ast_code.program.body[1].expression.left.name = "b"

console.log(generator(ast_code).code)

2、简单使用

const {parse} = require("@babel/parser")

const generator = require("@babel/generator").default;

const traverse = require("@babel/traverse").default;

// const fs = require('fs');

// const js_code = fs.readFileSync("....js",{encoding:'utf-8'});

js_code = "function hi(){console['log']('\x48\x65\x6c\x6f\x20\x57\x6f\x72\x6c\x64\x21')};hi();"

const ast_code = parse(js_code)

//console.log(ast_code)

const visitor = {

    'StringLiteral|FunctionDeclaration'(path){

        //delete path.node.extra

        //path.node.extra.raw = '\'' + path.node.extra.rawValue + '\'';

        //console.log(path.toString())  可以看当前节点的源代码 作者重写了toString方法

        //console.log(generator(path.node))   可看当前节点源码

         console.log(path.node.extra)

    }

};

//path  和 node 的区别

//node是节点  path比node大的多  构造函数，一般使用path

//path中的方法

//

traverse(ast_code,visitor);

//traverse从ast_code的时候要给整个节点（file）

const result_js_code = generator(ast_code);

console.log(result_js_code.code)

3、深入使用

const {parse} = require("@babel/parser")

const generator = require("@babel/generator").default;

const traverse = require("@babel/traverse").default;

const types = require("@babel/types");

//生成节点.和替换节点同时使用

// console.log(types.valueToNode('342342'));

//

// throw ""

// const fs = require('fs');

// const js_code = fs.readFileSync("....js",{encoding:'utf-8'});

//let js_code = "var f = function a(a,b) { return a + b + '嘿嘿' } a('你爸爸','****')";

var js_code = "var a = 8899+78979;b=a<<2;"

const ast_code = parse(js_code);

//console.log(ast_code)

const visitor = {

    //'StringLiteral|FunctionDeclaration'(path){

    'Identifier|BinaryExpression'(path){

        //path.node.extra.raw = '\'' + path.node.extra.rawValue + '\'';

        //console.log(path.toString())  可以看当前节点的源代码 作者重写了toString方法

        //console.log(generator(path.node))   可看当前节点源码

        //path.insertBefore(types.valueToNode(value='vefvdfvfd'))

        //result = path.findParent(function (result){return result.isVariableDeclaration()});

        //console.log(result.type)

        //

        //console.log(path.getSibling(0) +' ')

        //console.log(path.key)

        //console.log(path.getSibling(path.key + 1) + '');

        //if (path.node.name === "a"){

            path.evaluate().confident && path.replaceInline(types.valueToNode(path.evaluate().value))

        //}

        //console.log(path.container === path.parent)//true只是一种情况

        //path.insertAfter(types.valueToNode(value='vefgbvdfvfd'))

        //path.stop()

        //path.remove()

        //path.replaceInline(types.valueToNode('342342'));

        //console.log(path.node.extra)

    }

};

//path  和 node 的区别

//node是节点  path比node大的多  构造函数，一般使用path

//path中的方法

//1、path.stop()     停止本次的遍历，只想操作当前的节点

//2、path中的节点替换   replaceWith 替换节点 1对1

//                    replaceWithMultipe 替换的是节点 1对多

//                    replaceInline 自动识别，包含以上两种方法

//                    replaceWithSourceString  节点替换成源码的字符串,强制替换

//3、path.remove()    删除节点

//4、insertBefore  insertAfter 插入节点

//5、parent  与parentpath的区别  path.parentPath.node = path.parent

//6、path.findParent 向上遍历父节点，直到找到，满足回调函数要求的为止

//7、path.find  向上遍历 包含当前节点

//8、path.getFunctionParent() 向上找函数

//9、path.getStatementParent() 向上遍历，直到找到语法树为止，包含当前节点

//10、path.container  返回的是所在容器的节点（已写例子），如果是数组，返回的是所在的容器（没写例子）

//    listkey是容器的名字，key是当前节点在容器中的索引，

//    数组中path.key是当前节点在容器中的索引，其他的应用返回的是父节点的名字

//    数组中path.listkey返回的数组的名字，其他的应用返回的是未定义

//11、path.inList 判断是否为容器，返回布尔值

//12、path.getSibling(index) 获取统计节点的第一个key的path,获取下一个同级节点就是path.getSibling(path,key+1)

//13、unshiftContainer 与pushContainer，在容器的前/后插入节点，不常用

//14、path.evalutate()获取当前作用域的引用值(两种用法)，赋值替换和计算表达式

traverse(ast_code,visitor);

//traverse从ast_code的时候要给整个节点（file）

const result_js_code = generator(ast_code);

console.log(result_js_code.code)

4、进阶使用

const {parse} = require("@babel/parser")

const generator = require("@babel/generator").default;

const traverse = require("@babel/traverse").default;

const types = require("@babel/types");

var js_code = "function f(a){ a = 105 + a; a++; return a};const a = f(a=100);console.log(a)"

const ast_code = parse(js_code);

//scope操作作用域，会更方便的操作节点

//scope.block 获得标识符作用域，返回node对象

//获取标识符绑定 Binging  path.scope.getBinding(标识符)

//一般对标识符的修改都是从Binging走的，其中一些参数：regerenced表示标识符是否在其他的地方被引用

//作用域的遍历

//binding.scope.traverse()

//scope.rename 会同时修改引用标识符的位置，生成唯一标识符的犯法：path.scope.generateUidIde

//scope.dump() 打印当前作用域的信息

//scope.hasBingding("a") 查询是否有标识符的绑定，一般可以用getBingding代替

//scope.getAllBingdings() 获得当前作用域的全部绑定，并返回一个对象

//scope.hasReference("a") 查询节点是否有a标识符的引用

//scope.getBindingIdentifier('a') 获取Identifier 本身

const visitor = {

    //'StringLiteral|FunctionDeclaration'(path){

    // 'CallExpression'(path){

    //     console.log(path+'')

    //     console.log('-----')

    //     console.log(path.scope.path +'')

    //     console.log('------------------------------')

    FunctionDeclaration(path){

        //path.scope.rename("a","b");

        //console.log(path.scope.getAllBindings().a + '');

        console.log(path.scope.getBindingIdentifier("a"));

        console.log(generator(path.scope.getBindingIdentifier("a")).code);

        path.stop()

    }

}

traverse(ast_code,visitor);

//traverse从ast_code的时候要给整个节点（file）

const result_js_code = generator(ast_code);

console.log("=======")

console.log(result_js_code.code)
