使用node实现歌词滚动输出

使用node实现歌词滚动输出

运用fs,path,iconv三个模块实现歌词滚动打印.
// 动态显示歌词

const fs = require(‘fs’);
const path = require(‘path’);
const iconv = require(‘iconv-lite’);

//获取字幕文件路径
fs.readFile(path.join(__dirname, ‘./../lyrics/血染的风采.lrc’), (error, data) => {
var lines = iconv.decode(data, ‘gbk’).split(‘\n’);
// console.log(lines.length);
var regex = /[(\d{2}):(\d{2}).(\d{2})]\s(.+)/;

var begin = new Date().getTime();
// 遍历
lines.forEach((line) => {
// [00:32.67] 也许我告别 将不再回来
var matches = regex.exec(line);
if (matches) {
var m = parseFloat(matches[1]);
var s = parseFloat(matches[2]);
var f = parseFloat(matches[3]);
var lyric = matches[4]; // 当前行歌词不是立即执行
// 由于下达输出任务的时刻不同
var offset = new Date().getTime() - begin;
setTimeout(() => {
console.log(l
