GOGOCODE
全网最简单易上手，可读性最强的 AST 处理工具！
Install
npm install gogocode
快速开始
对于下面的代码
1const code = ` 2 const moment = require('moment'); 3 var a = 1; 4 const b = 2; 5 function log (x, y = 'World') { 6 console.log('a') 7 console.log(a, x, y); 8 } 9`;
创建一个 AST 实例
1const $ = require('gogocode'); 2const AST = $(code);
- 小明想将 所有的
a变量名替换为c，只需要
1$(code).replace('a', 'c')
-
小明改主意了，只想把
var a = 1里的变量名改为c，需要两步：- 取变量 a 的定义赋值，
1$(code).find('var a = 1');- 将
a变量名替换为c，并输出整体代码
1$(code) 2 .find('var a = 1') 3 .attr('declarations.0.id.name', 'c') 4 .root() 5 .generate();
这是直接操作AST的方式，有没有更简单的方法呢？有！
1$(code).replace(`var a = 1`, `var c = 1`)
replace确实用起来爽，但当你在分析转换代码时遇到replace覆盖不到的场景时，请用GoGoCode提供的其他api来精准操作AST吧！
- 小明又改主意了，想把所有定义语句的
a都改成c，只需要将目标语句改一下写成：
1$(code).replace(`var a = $_$`, `var c = $_$`)
看到这里，你应该已经理解
find和replace的第一参有点类似‘jquery 选择器’，而这里的选择器是你需要查找的代码片段，无论想要匹配多么复杂的代码都可以匹配到，其中$_$通配符可以匹配任意确定代码，代码选择器及通配符详细介绍 看这里
- 小明想试试将代码里的
var改为let，require改为import，他发现用 GoGoCode 真的可以像字符串的 replace 一样简单！
1$(code) 2.replace('var $_$1 = $_$2', 'let $_$1 = $_$2'); 3.replace('const $_$1 = require($_$2)', 'import $_$1 from $_$2')
关于如何书写选择器，以及replace详解，请见GoGoCode详细文档
API
获取节点
所有的节点获取操作都会返回一个新的AST实例，实例中可能包含多个AST节点路径，如find()、siblings()等，某些api返回的实例只会存在一个AST节点路径，如next()
AST.find(selector, options)
| 入参 | 说明 | 类型 | 默认值 | |
|---|---|---|---|---|
selector | 代码选择器，可以是代码也可以将代码中的部分内容挖空替换为通配符 | string | 无 | |
options | ignoreSequence | 匹配时是否忽略顺序 忽略顺序的情况： {a:$_$}匹配{b:1, a:2}需要严格按照顺序匹配的情况： function($_$, b){} 匹配function(a, b){} | boolean | false |
parseOptions | 同构造函数的parseOptions |
当selector中存在 $_$ 通配符时，返回的AST实例中存在 match 属性，也就是被 $_$ 匹配到的AST节点，按照$_$紧接着的key做聚合
如：$('const a = { key: 1, value: "gogo" }').find('const $_$1 = $_$2')
下图是选择器通过find匹配到的整句代码对应的AST节点：
下图是是 $_$1 和 $_$2 分别匹配到的节点以及对应的输出
.parent(level)
获取某个父节点
| 入参 | 说明 | 类型 | 默认值 |
|---|---|---|---|
level | 自内向外第n层父元素 | number | 0 |
.parents()
获取所有父节
.root()
获取根节点，对于js来说是type为'File'的节点，对于html来说是nodeType为'document'的节点
通常对AST进行操作之后需要获取root元素之后再输出
.siblings()
获取所有兄弟节点
.prev()
获取前一个节点
.prevAll()
获取当前节点之前的同级节点
.next()
获取后一个节点
.nextAll()
获取当前节点之后的同级节点
.each(callback)
以每一个匹配的元素作为上下文来执行一个函数。
| 入参 | 说明 | 类型 | 默认值 |
|---|---|---|---|
callback | 对于每个匹配的元素所要执行的函数 执行函数时，会给函数传递当前节点 node和index | function | 无 |
.eq(index)
获取当前链式操作中第N个AST对象
| 入参 | 说明 | 类型 | 默认值 |
|---|---|---|---|
index | 需要获取的AST对象的位置 | number | 0 |
操作节点
.attr()
获取或修改AST节点的属性，入参可分三种情况：
- 返回属性名称对应的节点或属性值
| 入参 | 说明 | 类型 | 默认值 | 举例 |
|---|---|---|---|---|
attrName | ast节点的属性名称，支持多层属性，通过.连接 | string | 无 | declarations declarations.0.id.name |
- 修改属性名称对应的节点或属性值
| 入参 | 说明 | 类型 | 举例 |
|---|---|---|---|
attrName | ast节点的属性名称，支持多层属性，通过.连接 | string | declarations declarations.0.id.name |
attrValue | 将第一个入参获取到的节点或属性修改为该入参 注意：字符串不会被解析为ast节点而是直接替换原有属性 | node string |
- 修改多个属性名称对应的节点或属性值
| 入参 | 类型 | 默认值 | 举例 | |
|---|---|---|---|---|
attrMap | attrName | string | 无 | declarations declarations.0.id.name |
attrValue | node | string | 无 |
1AST.attr('init', initNode) 2 3AST.attr({ 4 init: initNode, 5 'program.body.0.params.0.name': 'a' 6}) 7 8AST.attr('program.body.0.params.0.name')
.has(selector, options)
判断是否有某个子节点，返回值为boolean类型
入参同.find()
.clone()
返回由当前节点深度复制的新节点
.replace(selector, replacer)
在当前节点内部用replacer替换selector匹配到的代码，返回当前节点
| 入参 | 解释 | 类型 | 例 | |
|---|---|---|---|---|
selector | 代码选择器，可以是代码也可以将代码中的部分内容挖空替换为通配符 | string | var $_$1 = $_$2 | |
replacer | 替换代码，同代码选择器通配符顺序与selector的保持一致 也可以是确定的ast节点 | string | node | |
options | ignoreSequence | 匹配时是否忽略顺序 | object | 无 |
parseOptions | 解析入参 | object | 无 |
1AST.replace(`Component`, `module.exports = Magix.View.extend`); 2 3AST.replace( 4 `export default function calculateData($_$1){$_$2}`, 5 `function calculateData($_$1){$_$2}` 6) 7 8AST.replace( 9 `navigateToOutside({url: $_$})`, 10 `jm.attachUrlParams($_$)`, 11 options: { ignoreSequence: true } 12)
.replaceBy(replacerAST)
用replacerAST替换当前节点，返回新节点
| 入参 | 类型 |
|---|---|
replacerAST | AST node string |
.after(ast)
在当前节点后面插入一个同级别的节点，返回当前节点
| 入参 | 类型 |
|---|---|
ast | AST node string |
.before()
在当前节点前面插入一个同级别的节点，返回当前节点
| 入参 | 类型 |
|---|---|
ast | AST node string |
.append(attr, ast)
在当前节点内部某个数组属性的末尾插入一个子节点，返回当前节点
| 入参 | 类型 |
|---|---|
attr | 当前节点的数组属性名称 |
ast | AST node string |
- 为什么需要传入
attr？
因为某些节点中多个属性都为数组，如函数，存在入参params和函数体body两个数组子节点，必须通过attr来判断插入节点的位置
1AST 2.find('function $_$() {}') 3.append('params', 'b') 4.prepend('body', 'b = b || 1;')
.prepend()
在当前节点内部某个数组属性的首位插入一个子节点，返回当前节点
.empty()
清空当前节点所有子节点，返回当前节点
.remove()
移除当前节点，返回根节点
.generate()
将AST对象输出为代码
