Nodejs实现VScode搜索功能，递归读取文件夹匹配内容

阅读更多

VScode搜索功能图示：

 

 

关键点：读取目录文件夹，判断是否文件夹，若是递归继续读取，否则通过正则或普通匹配关键词。

               统计唯一文件名数量，统计总搜索记录数量累加，展示结果。

 

Core code：

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

// const basePath = path.resolve('src');
// const matchFile = /\.(jsx?|css)$/;
const basePath = path.normalize('D:\\Dev\\xxx\\src\\main\\webapp');
const matchFile = /\.(jsp?|css)$/;
const searchWord = /\/assetWithdraw\/.*?\.html/img;
const matchList = {};
let fileCount = 0;

const isDirectory = source => fs.lstatSync(source).isDirectory();
const getDirectories = source =>
  fs.readdirSync(source).map(fileName => {
    const newPath = path.join(source, fileName);
    if (isDirectory(newPath)) {
      getDirectories(newPath);
    } else {
      if (matchFile.test(fileName)) {
        const contents = fs.readFileSync(newPath, 'utf8');
        let matchs = contents.match(searchWord);
        if (matchs) {
          fileCount += 1;
          matchs.map(v => {
            matchList[newPath] = (matchList[newPath] || 0) + 1;
          });
        }
      }
    }
  });

getDirectories(basePath);

const sortList = Object.keys(matchList);
console.log(`Stat: ${Object.values(matchList).reduce((a,b) => a+b, 0)} results in ${fileCount} files (Unique of ${sortList.length})\n`);
console.log(sortList.map((v, i) => `${i+1}, ${v} (${matchList[v]})`).join('\n'));

 

搜索结果print：

Stat: 179 results in 65 files (Unique of 65)
