Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ast) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

使用方法

encodingConversion

const {encodingConversion} = require('ast')
const parser    = require("@babel/parser");
const traverse  = require("@babel/traverse").default;
const generator = require("@babel/generator").default;

let sourceCode = "\u0068\u0061\u006e\u006c\u0069\u006e\u0067"

let ast = parser.parse(sourceCode);
traverse(ast, encodingConversion)

let {code} = generator(ast,opts = {jsescOption:{"minimal":true}});

console.log(code);

output:
hanling

ConstantCalculate

const {ConstantCalculate} = require("ast");

const {parse} = require("@babel/parser");
const traverse = require("@babel/traverse").default;
const generator = require("@babel/generator").default;

let jscode = "var a = 123 + 456;\n" +
    "var b = 456 - 123;\n" +
    "var ab= a + b;\n" +
    "var c = !![];";

let ast = parse(jscode);

traverse(ast, ConstantCalculate);
let {code} = generator(ast);
console.log(code);


output:
var a = 579;
var b = 333;
var ab = 912;
var c = true;

resolveSequence

const {resolveSequence} = require("ast");

const {parse} = require("@babel/parser");
const traverse = require("@babel/traverse").default;
const generator = require("@babel/generator").default;

let jscode =
    `
function func() {
  return a = 1, b = 2, a + b;
}
`
let ast = parse(jscode);

traverse(ast, resolveSequence);
let {code} = generator(ast);
console.log(code);


output:
function func() {
    a = 1;
    b = 2;
    return a + b;
}
